## `influxdb` sink
|
|
|
|
The `influxdb` sink uses the official [InfluxDB golang client](https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2) to write the metrics to an InfluxDB database in a **blocking** fashion. It provides only support for V2 write endpoints (InfluxDB 1.8.0 or later).
|
|
|
|
### Configuration structure
|
|
|
|
```json
|
|
{
|
|
"<name>": {
|
|
"type": "influxdb",
|
|
"database" : "mymetrics",
|
|
"host": "dbhost.example.com",
|
|
"port": "4222",
|
|
"user": "exampleuser",
|
|
"password" : "examplepw",
|
|
"organization": "myorg",
|
|
"ssl": true,
|
|
"flush_delay" : "1s",
|
|
"batch_size" : 1000,
|
|
"use_gzip": true,
|
|
"precision": "s",
|
|
"process_messages" : {
|
|
"see" : "docs of message processor for valid fields"
|
|
},
|
|
"meta_as_tags" : []
|
|
}
|
|
}
|
|
```
|
|
|
|
- `type`: makes the sink an `influxdb` sink
|
|
- `database`: All metrics are written to this bucket
|
|
- `host`: Hostname of the InfluxDB database server
|
|
- `port`: Port number (as string) of the InfluxDB database server
|
|
- `user`: Username for basic authentication
|
|
- `password`: Password for basic authentication
|
|
- `organization`: Organization in the InfluxDB
|
|
- `ssl`: Use SSL connection
|
|
- `flush_delay`: Group metrics coming in to a single batch
|
|
- `batch_size`: Maximal batch size. If `batch_size` is reached before the end of `flush_delay`, the metrics are sent without further delay
|
|
- `precision`: Precision of the timestamp. Valid values are 's', 'ms', 'us' and 'ns'. (default is 's')
|
|
- `process_messages`: Process messages with given rules before progressing or dropping, see [here](../pkg/messageProcessor/README.md) (optional)
|
|
- `meta_as_tags`: print all meta information as tags in the output (deprecated, optional)
|
|
|
|
Influx client options:
|
|
=======
|
|
- `batch_size`: Maximal batch size
|
|
- `meta_as_tags`: move meta information keys to tags (optional)
|
|
- `http_request_timeout`: HTTP request timeout
|
|
- `retry_interval`: retry interval
|
|
- `max_retry_interval`: maximum delay between each retry attempt
|
|
- `retry_exponential_base`: base for the exponential retry delay
|
|
- `max_retries`: maximum count of retry attempts of failed writes
|
|
- `max_retry_time`: maximum total retry timeout
|
|
- `use_gzip`: Specify whether to use GZip compression in write requests
|
|
|
|
### Using `influxdb` sink for communication with cc-metric-store
|
|
|
|
The cc-metric-store only accepts metrics with a timestamp precision in seconds, so it is required to use `"precision": "s"`. |
