influxdb sink

The influxdb sink uses the official InfluxDB golang client 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

{
  "<name>": {
    "type": "influxdb",
    "meta_as_tags" : true,
    "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
  }
}

• type: makes the sink an influxdb sink
• meta_as_tags: print all meta information as tags in the output (optional)
• 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

Influx client options:

• 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
