This service can be deployed using docker containers.
|
||||
Docker compose file is available in `<project_root>/docker/addons/influxdb-writer/docker-compose.yml`. Besides database
|
||||
and writer service, it contains [Grafana platform](https://grafana.com/) which can be used for database
|
||||
and writer service, it contains InfluxData Web Admin Interface which can be used for database
|
||||
exploration and data visualization and analytics. In order to run Mainflux InfluxDB writer, execute the following command:
|
||||
|
||||
```bash
|
||||
docker-compose -f docker/addons/influxdb-writer/docker-compose.yml up -d
|
||||
```
|
||||
|
||||
And, to use the default .env file, execute the following command:
|
||||
|
||||
```bash
|
||||
docker-compose -f docker/addons/influxdb-writer/docker-compose.yml up --env-file docker/.env -d
|
||||
```
|
||||
|
||||
_Please note that you need to start core services before the additional ones._
|
||||
|
||||
## Usage
|
||||
|
||||
Starting service will start consuming normalized messages in SenML format.

|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work

(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.

2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,

|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|

||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must

||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and

## How To Use
|
||||
|
||||
### Installation
|
||||
**Go 1.17** or later is required.
|
||||
|
||||
#### Go mod project
|
||||
1. Add the latest version of the client package to your project dependencies (go.mod).
|
||||
```sh
|
||||
go get github.com/influxdata/influxdb-client-go/v2
|
||||
```
|
||||
1. Add import `github.com/influxdata/influxdb-client-go/v2` to your source code.
|
||||
#### GOPATH project
|
||||
```sh
|
||||
go get github.com/influxdata/influxdb-client-go
|
||||
```
|
||||
Note: To have _go get_ in the GOPATH mode, the environment variable `GO111MODULE` must have the `off` value.
|
||||
|
||||
### Basic Example
|
||||
The following example demonstrates how to write data to InfluxDB 2 and read them back using the Flux language:
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"context"
|
||||
"fmt"
|
||||
"time"
|
||||
|
||||
"github.com/influxdata/influxdb-client-go/v2"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Create a new client using an InfluxDB server base URL and an authentication token
|
||||
client := influxdb2.NewClient("http://localhost:8086", "my-token")
|
||||
// Use blocking write client for writes to desired bucket
|
||||
writeAPI := client.WriteAPIBlocking("my-org", "my-bucket")
|
||||
// Create point using full params constructor
|
||||
p := influxdb2.NewPoint("stat",
|
||||
map[string]string{"unit": "temperature"},
|
||||
map[string]interface{}{"avg": 24.5, "max": 45.0},
|
||||
time.Now())
|
||||
// write point immediately
|
||||
writeAPI.WritePoint(context.Background(), p)
|
||||
// Create point using fluent style
|
||||
p = influxdb2.NewPointWithMeasurement("stat").
|
||||
AddTag("unit", "temperature").
|
||||
AddField("avg", 23.2).
|
||||
AddField("max", 45.0).
|
||||
SetTime(time.Now())
|
||||
err := writeAPI.WritePoint(context.Background(), p)
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
// Or write directly line protocol
|
||||
line := fmt.Sprintf("stat,unit=temperature avg=%f,max=%f", 23.5, 45.0)
|
||||
err = writeAPI.WriteRecord(context.Background(), line)
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
|
||||
// Get query client
|
||||
queryAPI := client.QueryAPI("my-org")
|
||||
// Get parser flux query result
|
||||
result, err := queryAPI.Query(context.Background(), `from(bucket:"my-bucket")|> range(start: -1h) |> filter(fn: (r) => r._measurement == "stat")`)
|
||||
if err == nil {
|
||||
// Use Next() to iterate over query result lines
|
||||
for result.Next() {
|
||||
// Observe when there is new grouping key producing new table
|
||||
if result.TableChanged() {
|
||||
fmt.Printf("table: %s\n", result.TableMetadata().String())
|
||||
}
|
||||
// read result
|
||||
fmt.Printf("row: %s\n", result.Record().String())
|
||||
}
|
||||
if result.Err() != nil {
|
||||
fmt.Printf("Query error: %s\n", result.Err().Error())
|
||||
}
|
||||
} else {
|
||||
panic(err)
|
||||
}
|
||||
// Ensures background processes finishes
|
||||
client.Close()
|
||||
}
|
||||
```
|
||||
### Options
|
||||
The InfluxDBClient uses set of options to configure behavior. These are available in the [Options](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2#Options) object
|
||||
Creating a client instance using
|
||||
```go
|
||||
client := influxdb2.NewClient("http://localhost:8086", "my-token")
|
||||
```
|
||||
will use the default options.
|
||||
|
||||
To set different configuration values, e.g. to set gzip compression and trust all server certificates, get default options
|
||||
and change what is needed:
|
||||
```go
|
||||
client := influxdb2.NewClientWithOptions("http://localhost:8086", "my-token",
|
||||
influxdb2.DefaultOptions().
|
||||
SetUseGZip(true).
|
||||
SetTLSConfig(&tls.Config{
|
||||
InsecureSkipVerify: true,
|
||||
}))
|
||||
```
|
||||
### Writes
|
||||
|
||||
Client offers two ways of writing, non-blocking and blocking.
|
||||
|
||||
### Non-blocking write client
|
||||
Non-blocking write client uses implicit batching. Data are asynchronously
|
||||
written to the underlying buffer and they are automatically sent to a server when the size of the write buffer reaches the batch size, default 5000, or the flush interval, default 1s, times out.
|
||||
Writes are automatically retried on server back pressure.
|
||||
|
||||
This write client also offers synchronous blocking method to ensure that write buffer is flushed and all pending writes are finished,
|
||||
see [Flush()](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2/api#WriteAPI.Flush) method.
|
||||
Always use [Close()](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2#Client.Close) method of the client to stop all background processes.
|
||||
|
||||
Asynchronous write client is recommended for frequent periodic writes.
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"math/rand"
|
||||
"time"
|
||||
|
||||
"github.com/influxdata/influxdb-client-go/v2"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Create a new client using an InfluxDB server base URL and an authentication token
|
||||
// and set batch size to 20
|
||||
client := influxdb2.NewClientWithOptions("http://localhost:8086", "my-token",
|
||||
influxdb2.DefaultOptions().SetBatchSize(20))
|
||||
// Get non-blocking write client
|
||||
writeAPI := client.WriteAPI("my-org","my-bucket")
|
||||
// write some points
|
||||
for i := 0; i <100; i++ {
|
||||
// create point
|
||||
p := influxdb2.NewPoint(
|
||||
"system",
|
||||
map[string]string{
|
||||
"id": fmt.Sprintf("rack_%v", i%10),
|
||||
"vendor": "AWS",
|
||||
"hostname": fmt.Sprintf("host_%v", i%100),
|
||||
},
|
||||
map[string]interface{}{
|
||||
"temperature": rand.Float64() * 80.0,
|
||||
"disk_free": rand.Float64() * 1000.0,
|
||||
"disk_total": (i/10 + 1) * 1000000,
|
||||
"mem_total": (i/100 + 1) * 10000000,
|
||||
"mem_free": rand.Uint64(),
|
||||
},
|
||||
time.Now())
|
||||
// write asynchronously
|
||||
writeAPI.WritePoint(p)
|
||||
}
|
||||
// Force all unwritten data to be sent
|
||||
writeAPI.Flush()
|
||||
// Ensures background processes finishes
|
||||
client.Close()
|
||||
}
|
||||
```
|
||||
### Handling of failed async writes
|
||||
WriteAPI by default continues with retrying of failed writes.
|
||||
Retried are automatically writes that fail on a connection failure or when server returns response HTTP status code >= 429.
|
||||
|
||||
Retrying algorithm uses random exponential strategy to set retry time.
|
||||
The delay for the next retry attempt is a random value in the interval _retryInterval * exponentialBase^(attempts)_ and _retryInterval * exponentialBase^(attempts+1)_.
|
||||
If writes of batch repeatedly fails, WriteAPI continues with retrying until _maxRetries_ is reached or the overall retry time of batch exceeds _maxRetryTime_.
|
||||
|
||||
The defaults parameters (part of the WriteOptions) are:
|
||||
- _retryInterval_=5,000ms
|
||||
- _exponentialBase_=2
|
||||
- _maxRetryDelay_=125,000ms
|
||||
- _maxRetries_=5
|
||||
- _maxRetryTime_=180,000ms
|
||||
|
||||
Retry delays are by default randomly distributed within the ranges:
|
||||
1. 5,000-10,000
|
||||
1. 10,000-20,000
|
||||
1. 20,000-40,000
|
||||
1. 40,000-80,000
|
||||
1. 80,000-125,000
|
||||
|
||||
Setting _retryInterval_ to 0 disables retry strategy and any failed write will discard the batch.
|
||||
|
||||
[WriteFailedCallback](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2/api#WriteFailedCallback) allows advanced controlling of retrying.
|
||||
It is synchronously notified in case async write fails.
|
||||
It controls further batch handling by its return value. If it returns `true`, WriteAPI continues with retrying of writes of this batch. Returned `false` means the batch should be discarded.
|
||||
|
||||
### Reading async errors
|
||||
WriteAPI automatically logs write errors. Use [Errors()](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2/api#WriteAPI.Errors) method, which returns the channel for reading errors occuring during async writes, for writing write error to a custom target:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"math/rand"
|
||||
"time"
|
||||
|
||||
"github.com/influxdata/influxdb-client-go/v2"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Create a new client using an InfluxDB server base URL and an authentication token
|
||||
client := influxdb2.NewClient("http://localhost:8086", "my-token")
|
||||
// Get non-blocking write client
|
||||
writeAPI := client.WriteAPI("my-org", "my-bucket")
|
||||
// Get errors channel
|
||||
errorsCh := writeAPI.Errors()
|
||||
// Create go proc for reading and logging errors
|
||||
go func() {
|
||||
for err := range errorsCh {
|
||||
fmt.Printf("write error: %s\n", err.Error())
|
||||
}
|
||||
}()
|
||||
// write some points
|
||||
for i := 0; i < 100; i++ {
|
||||
// create point
|
||||
p := influxdb2.NewPointWithMeasurement("stat").
|
||||
AddTag("id", fmt.Sprintf("rack_%v", i%10)).
|
||||
AddTag("vendor", "AWS").
|
||||
AddTag("hostname", fmt.Sprintf("host_%v", i%100)).
|
||||
AddField("temperature", rand.Float64()*80.0).
|
||||
AddField("disk_free", rand.Float64()*1000.0).
|
||||
AddField("disk_total", (i/10+1)*1000000).
|
||||
AddField("mem_total", (i/100+1)*10000000).
|
||||
AddField("mem_free", rand.Uint64()).
|
||||
SetTime(time.Now())
|
||||
// write asynchronously
|
||||
writeAPI.WritePoint(p)
|
||||
}
|
||||
// Force all unwritten data to be sent
|
||||
writeAPI.Flush()
|
||||
// Ensures background processes finishes
|
||||
client.Close()
|
||||
}
|
||||
```
|
||||
|
||||
### Blocking write client
|
||||
Blocking write client writes given point(s) synchronously. It doesn't do implicit batching. Batch is created from given set of points.
|
||||
Implicit batching can be enabled with `WriteAPIBlocking.EnableBatching()`.
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"context"
|
||||
"fmt"
|
||||
"math/rand"
|
||||
"time"
|
||||
|
||||
"github.com/influxdata/influxdb-client-go/v2"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Create a new client using an InfluxDB server base URL and an authentication token
|
||||
client := influxdb2.NewClient("http://localhost:8086", "my-token")
|
||||
// Get blocking write client
|
||||
writeAPI := client.WriteAPIBlocking("my-org","my-bucket")
|
||||
// write some points
|
||||
for i := 0; i <100; i++ {
|
||||
// create data point
|
||||
p := influxdb2.NewPoint(
|
||||
"system",
|
||||
map[string]string{
|
||||
"id": fmt.Sprintf("rack_%v", i%10),
|
||||
"vendor": "AWS",
|
||||
"hostname": fmt.Sprintf("host_%v", i%100),
|
||||
},
|
||||
map[string]interface{}{
|
||||
"temperature": rand.Float64() * 80.0,
|
||||
"disk_free": rand.Float64() * 1000.0,
|
||||
"disk_total": (i/10 + 1) * 1000000,
|
||||
"mem_total": (i/100 + 1) * 10000000,
|
||||
"mem_free": rand.Uint64(),
|
||||
},
|
||||
time.Now())
|
||||
// write synchronously
|
||||
err := writeAPI.WritePoint(context.Background(), p)
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
}
|
||||
// Ensures background processes finishes
|
||||
client.Close()
|
||||
}
|
||||
```
|
||||
|
||||
### Queries
|
||||
Query client offers retrieving of query results to a parsed representation in a [QueryTableResult](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2/api#QueryTableResult) or to a raw string.
|
||||
|
||||
### QueryTableResult
|
||||
QueryTableResult offers comfortable way how to deal with flux query CSV response. It parses CSV stream into FluxTableMetaData, FluxColumn and FluxRecord objects
|
||||
for easy reading the result.
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"context"
|
||||
"fmt"
|
||||
|
||||
"github.com/influxdata/influxdb-client-go/v2"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Create a new client using an InfluxDB server base URL and an authentication token
|
||||
client := influxdb2.NewClient("http://localhost:8086", "my-token")
|
||||
// Get query client
|
||||
queryAPI := client.QueryAPI("my-org")
|
||||
// get QueryTableResult
|
||||
result, err := queryAPI.Query(context.Background(), `from(bucket:"my-bucket")|> range(start: -1h) |> filter(fn: (r) => r._measurement == "stat")`)
|
||||
if err == nil {
|
||||
// Iterate over query response
|
||||
for result.Next() {
|
||||
// Notice when group key has changed
|
||||
if result.TableChanged() {
|
||||
fmt.Printf("table: %s\n", result.TableMetadata().String())
|
||||
}
|
||||
// Access data
|
||||
fmt.Printf("value: %v\n", result.Record().Value())
|
||||
}
|
||||
// check for an error
|
||||
if result.Err() != nil {
|
||||
fmt.Printf("query parsing error: %s\n", result.Err().Error())
|
||||
}
|
||||
} else {
|
||||
panic(err)
|
||||
}
|
||||
// Ensures background processes finishes
|
||||
client.Close()
|
||||
}
|
||||
```
|
||||
|
||||
### Raw
|
||||
[QueryRaw()](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2/api#QueryAPI.QueryRaw) returns raw, unparsed, query result string and process it on your own. Returned csv format
|
||||
can be controlled by the third parameter, query dialect.
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"context"
|
||||
"fmt"
|
||||
|
||||
"github.com/influxdata/influxdb-client-go/v2"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Create a new client using an InfluxDB server base URL and an authentication token
|
||||
client := influxdb2.NewClient("http://localhost:8086", "my-token")
|
||||
// Get query client
|
||||
queryAPI := client.QueryAPI("my-org")
|
||||
// Query and get complete result as a string
|
||||
// Use default dialect
|
||||
result, err := queryAPI.QueryRaw(context.Background(), `from(bucket:"my-bucket")|> range(start: -1h) |> filter(fn: (r) => r._measurement == "stat")`, influxdb2.DefaultDialect())
|
||||
if err == nil {
|
||||
fmt.Println("QueryResult:")
|
||||
fmt.Println(result)
|
||||
} else {
|
||||
panic(err)
|
||||
}
|
||||
// Ensures background processes finishes
|
||||
client.Close()
|
||||
}
|
||||
```
|
||||
### Parametrized Queries
|
||||
InfluxDB Cloud supports [Parameterized Queries](https://docs.influxdata.com/influxdb/cloud/query-data/parameterized-queries/)
|
||||
that let you dynamically change values in a query using the InfluxDB API. Parameterized queries make Flux queries more
|
||||
reusable and can also be used to help prevent injection attacks.
|
||||
|
||||
InfluxDB Cloud inserts the params object into the Flux query as a Flux record named `params`. Use dot or bracket
|
||||
notation to access parameters in the `params` record in your Flux query. Parameterized Flux queries support only `int`
|
||||
, `float`, and `string` data types. To convert the supported data types into
|
||||
other [Flux basic data types, use Flux type conversion functions](https://docs.influxdata.com/influxdb/cloud/query-data/parameterized-queries/#supported-parameter-data-types).
|
||||
|
||||
Query parameters can be passed as a struct or map. Param values can be only simple types or `time.Time`.
|
||||
The name of the parameter represented by a struct field can be specified by JSON annotation.
|
||||
|
||||
Parameterized query example:
|
||||
> :warning: Parameterized Queries are supported only in InfluxDB Cloud. There is no support in InfluxDB OSS currently.
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"context"
|
||||
"fmt"
|
||||
|
||||
"github.com/influxdata/influxdb-client-go/v2"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Create a new client using an InfluxDB server base URL and an authentication token
|
||||
client := influxdb2.NewClient("http://localhost:8086", "my-token")
|
||||
// Get query client
|
||||
queryAPI := client.QueryAPI("my-org")
|
||||
// Define parameters
|
||||
parameters := struct {
|
||||
Start string `json:"start"`
|
||||
Field string `json:"field"`
|
||||
Value float64 `json:"value"`
|
||||
}{
|
||||
"-1h",
|
||||
"temperature",
|
||||
25,
|
||||
}
|
||||
// Query with parameters
|
||||
query := `from(bucket:"my-bucket")
|
||||
|> range(start: duration(params.start))
|
||||
|> filter(fn: (r) => r._measurement == "stat")
|
||||
|> filter(fn: (r) => r._field == params.field)
|
||||
|> filter(fn: (r) => r._value > params.value)`
|
||||
|
||||
// Get result
|
||||
result, err := queryAPI.QueryWithParams(context.Background(), query, parameters)
|
||||
if err == nil {
|
||||
// Iterate over query response
|
||||
for result.Next() {
|
||||
// Notice when group key has changed
|
||||
if result.TableChanged() {
|
||||
fmt.Printf("table: %s\n", result.TableMetadata().String())
|
||||
}
|
||||
// Access data
|
||||
fmt.Printf("value: %v\n", result.Record().Value())
|
||||
}
|
||||
// check for an error
|
||||
if result.Err() != nil {
|
||||
fmt.Printf("query parsing error: %s\n", result.Err().Error())
|
||||
}
|
||||
} else {
|
||||
panic(err)
|
||||
}
|
||||
// Ensures background processes finishes
|
||||
client.Close()
|
||||
}
|
||||
```
|
||||
|
||||
### Concurrency
|
||||
InfluxDB Go Client can be used in a concurrent environment. All its functions are thread-safe.
|
||||
|
||||
The best practise is to use a single `Client` instance per server URL. This ensures optimized resources usage,
|
||||
most importantly reusing HTTP connections.
|
||||
|
||||
For efficient reuse of HTTP resources among multiple clients, create an HTTP client and use `Options.SetHTTPClient()` for setting it to all clients:
|
||||
```go
|
||||
// Create HTTP client
|
||||
httpClient := &http.Client{
|
||||
Timeout: time.Second * time.Duration(60),
|
||||
Transport: &http.Transport{
|
||||
DialContext: (&net.Dialer{
|
||||
Timeout: 5 * time.Second,
|
||||
}).DialContext,
|
||||
TLSHandshakeTimeout: 5 * time.Second,
|
||||
TLSClientConfig: &tls.Config{
|
||||
InsecureSkipVerify: true,
|
||||
},
|
||||
MaxIdleConns: 100,
|
||||
MaxIdleConnsPerHost: 100,
|
||||
IdleConnTimeout: 90 * time.Second,
|
||||
},
|
||||
}
|
||||
// Client for server 1
|
||||
client1 := influxdb2.NewClientWithOptions("https://server:8086", "my-token", influxdb2.DefaultOptions().SetHTTPClient(httpClient))
|
||||
// Client for server 2
|
||||
client2 := influxdb2.NewClientWithOptions("https://server:9999", "my-token2", influxdb2.DefaultOptions().SetHTTPClient(httpClient))
|
||||
```
|
||||
|
||||
Client ensures that there is a single instance of each server API sub-client for the specific area. E.g. a single `WriteAPI` instance for each org/bucket pair,
|
||||
a single `QueryAPI` for each org.
|
||||
|
||||
Such a single API sub-client instance can be used concurrently:
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"math/rand"
|
||||
"sync"
|
||||
"time"
|
||||
|
||||
influxdb2 "github.com/influxdata/influxdb-client-go"
|
||||
"github.com/influxdata/influxdb-client-go/v2/api/write"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Create client
|
||||
client := influxdb2.NewClient("http://localhost:8086", "my-token")
|
||||
// Ensure closing the client
|
||||
defer client.Close()
|
||||
|
||||
// Get write client
|
||||
writeApi := client.WriteAPI("my-org", "my-bucket")
|
||||
|
||||
// Create channel for points feeding
|
||||
pointsCh := make(chan *write.Point, 200)
|
||||
|
||||
threads := 5
|
||||
|
||||
var wg sync.WaitGroup
|
||||
go func(points int) {
|
||||
for i := 0; i < points; i++ {
|
||||
p := influxdb2.NewPoint("meas",
|
||||
map[string]string{"tag": "tagvalue"},
|
||||
map[string]interface{}{"val1": rand.Int63n(1000), "val2": rand.Float64()*100.0 - 50.0},
|
||||
time.Now())
|
||||
pointsCh <- p
|
||||
}
|
||||
close(pointsCh)
|
||||
}(1000000)
|
||||
|
||||
// Launch write routines
|
||||
for t := 0; t < threads; t++ {
|
||||
wg.Add(1)
|
||||
go func() {
|
||||
for p := range pointsCh {
|
||||
writeApi.WritePoint(p)
|
||||
}
|
||||
wg.Done()
|
||||
}()
|
||||
}
|
||||
// Wait for writes complete
|
||||
wg.Wait()
|
||||
}
|
||||
```
|
||||
|
||||
### Proxy and redirects
|
||||
You can configure InfluxDB Go client behind a proxy in two ways:
|
||||
1. Using environment variable
|
||||
Set environment variable `HTTP_PROXY` (or `HTTPS_PROXY` based on the scheme of your server url).
|
||||
e.g. (linux) `export HTTP_PROXY=http://my-proxy:8080` or in Go code `os.Setenv("HTTP_PROXY","http://my-proxy:8080")`
|
||||
|
||||
1. Configure `http.Client` to use proxy<br>
|
||||
Create a custom `http.Client` with a proxy configuration:
|
||||
```go
|
||||
proxyUrl, err := url.Parse("http://my-proxy:8080")
|
||||
httpClient := &http.Client{
|
||||
Transport: &http.Transport{
|
||||
Proxy: http.ProxyURL(proxyUrl)
|
||||
}
|
||||
}
|
||||
client := influxdb2.NewClientWithOptions("http://localhost:8086", token, influxdb2.DefaultOptions().SetHTTPClient(httpClient))
|
||||
```
|
||||
|
||||
Client automatically follows HTTP redirects. The default redirect policy is to follow up to 10 consecutive requests.
|
||||
Due to a security reason _Authorization_ header is not forwarded when redirect leads to a different domain.
|
||||
To overcome this limitation you have to set a custom redirect handler:
|
||||
```go
|
||||
token := "my-token"
|
||||
|
||||
httpClient := &http.Client{
|
||||
CheckRedirect: func(req *http.Request, via []*http.Request) error {
|
||||
req.Header.Add("Authorization","Token " + token)
|
||||
return nil
|
||||
},
|
||||
}
|
||||
client := influxdb2.NewClientWithOptions("http://localhost:8086", token, influxdb2.DefaultOptions().SetHTTPClient(httpClient))
|
||||
```
|
||||
|
||||
### Checking Server State
|
||||
There are three functions for checking whether a server is up and ready for communication:
|
||||
|
||||
| Function| Description | Availability |
|
||||
|:----------|:----------|:----------|
|
||||
| [Health()](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2#Client.Health) | Detailed info about the server status, along with version string | OSS |
|
||||
| [Ready()](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2#Client.Ready) | Server uptime info | OSS |
|
||||
| [Ping()](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2#Client.Ping) | Whether a server is up | OSS, Cloud |
|
||||
|
||||
Only the [Ping()](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2#Client.Ping) function works in InfluxDB Cloud server.
|
||||
|
||||
## InfluxDB 1.8 API compatibility
|
||||
|
||||
[InfluxDB 1.8.0 introduced forward compatibility APIs](https://docs.influxdata.com/influxdb/latest/tools/api/#influxdb-2-0-api-compatibility-endpoints) for InfluxDB 2.0. This allow you to easily move from InfluxDB 1.x to InfluxDB 2.0 Cloud or open source.
|
||||
|
||||
Client API usage differences summary:
|
||||
1. Use the form `username:password` for an **authentication token**. Example: `my-user:my-password`. Use an empty string (`""`) if the server doesn't require authentication.
|
||||
1. The organization parameter is not used. Use an empty string (`""`) where necessary.
|
||||
1. Use the form `database/retention-policy` where a **bucket** is required. Skip retention policy if the default retention policy should be used. Examples: `telegraf/autogen`, `telegraf`.
|
||||
|
||||
The following forward compatible APIs are available:
|
||||
|
||||
| API | Endpoint | Description |
|
||||
|:----------|:----------|:----------|
|
||||
| [WriteAPI](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2/api#WriteAPI) (also [WriteAPIBlocking](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2/api#WriteAPIBlocking))| [/api/v2/write](https://docs.influxdata.com/influxdb/v2.0/write-data/developer-tools/api/) | Write data to InfluxDB 1.8.0+ using the InfluxDB 2.0 API |
|
||||
| [QueryAPI](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2/api#QueryAPI) | [/api/v2/query](https://docs.influxdata.com/influxdb/v2.0/query-data/execute-queries/influx-api/) | Query data in InfluxDB 1.8.0+ using the InfluxDB 2.0 API and [Flux](https://docs.influxdata.com/flux/latest/) endpoint should be enabled by the [`flux-enabled` option](https://docs.influxdata.com/influxdb/v1.8/administration/config/#flux-enabled-false)
|
||||
| [Health()](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2#Client.Health) | [/health](https://docs.influxdata.com/influxdb/v2.0/api/#tag/Health) | Check the health of your InfluxDB instance |
|
||||

# line-protocol
|
||||
|
||||
This is an encoder for the influx [line protocol.](https://docs.influxdata.com/influxdb/latest/write_protocols/line_protocol_reference/)
|
||||
|
||||
It has an interface similar to the standard library's `json.Encoder`.
|
||||
|
||||
|
||||
### some caveats.
|
||||
- It is not concurrency-safe. If you want to make multiple calls to `Encoder.Encode` concurrently you have to manage the concurrency yourself.
|
||||
- It can only encode values that are uint64, int64, int, float32, float64, string, or bool.
|
||||
- Ints are converted to int64, float32's to float64.
|
||||
- If UintSupport is not set, uint64s are converted to int64's and if they are larger than the max int64, they get truncated to the max int64 instead of overflowing.
|
||||
|
||||
|
||||
### Example:
|
||||
```go
|
||||
buf := &bytes.Buffer{}
|
||||
serializer := protocol.NewEncoder(buf)
|
||||
serializer.SetMaxLineBytes(1024)
|
||||
serializer.SetFieldTypeSupport(UintSupport)
|
||||
serializer.Encode(e) // where e is something that implements the protocol.Metric interface

// Package publicsuffix provides a public suffix list based on data from

|

// A public suffix is one under which Internet users can directly register

// names. It is related to, but different from, a TLD (top level domain).
|
||||
//
|
||||
// "com" is a TLD (top level domain). Top level means it has no dots.
|
||||
//
|
||||
// "com" is also a public suffix. Amazon and Google have registered different
|
||||
// siblings under that domain: "amazon.com" and "google.com".
|
||||
//
|
||||
// "au" is another TLD, again because it has no dots. But it's not "amazon.au".
|
||||
// Instead, it's "amazon.com.au".
|
||||
//
|
||||
// "com.au" isn't an actual TLD, because it's not at the top level (it has
|
||||
// dots). But it is an eTLD (effective TLD), because that's the branching point
|
||||
// for domain name registrars.
|
||||
//
|
||||
// Another name for "an eTLD" is "a public suffix". Often, what's more of
|
||||
// interest is the eTLD+1, or one more label than the public suffix. For
|
||||
// example, browsers partition read/write access to HTTP cookies according to
|
||||
// the eTLD+1. Web pages served from "amazon.com.au" can't read cookies from
|
||||
// "google.com.au", but web pages served from "maps.google.com" can share
|
||||
// cookies from "www.google.com", so you don't have to sign into Google Maps
|
||||
// separately from signing into Google Web Search. Note that all four of those
|
||||
// domains have 3 labels and 2 dots. The first two domains are each an eTLD+1,
|
||||
// the last two are not (but share the same eTLD+1: "google.com").
|
||||
//
|
||||
// All of these domains have the same eTLD+1:
|
||||
// - "www.books.amazon.co.uk"
|
||||
// - "books.amazon.co.uk"
|
||||
// - "amazon.co.uk"
|
||||
//
|
||||
// Specifically, the eTLD+1 is "amazon.co.uk", because the eTLD is "co.uk".
