This receiver accepts metrics data as InfluxDB Line Protocol.

Write endpoints exist at /write (InfluxDB 1.x compatibility) and /api/v2/write (InfluxDB 2.x compatibility). Write query parameters db/rp (InfluxDB 1.x) and org/bucket (InfluxDB 2.x) are ignored. Write query parameter precision is optional, defaults to ns.

Write responses:

• 204: success, no further response needed (no content)
• 400: permanent failure; check response body for details
• 500: retryable error; check response body for details

Configuration

The following configuration options are supported:

• endpoint (default = 0.0.0.0:8086) HTTP service endpoint for the line protocol receiver

The full list of settings exposed for this receiver are documented in config.go.

Example:

receivers:
  influxdb:
    endpoint: 0.0.0.0:8080

Definitions

InfluxDB is an open-source time series database.

Telegraf is an open-source metrics agent, similar to the OpenTelemetry Collector. Telegraf has hundreds of plugins.

Line protocol is a textual HTTP payload format used to move metrics between Telegraf agents and InfluxDB instances.

Schema

The InfluxDB->OpenTelemetry conversion schema and implementation are hosted at https://github.com/influxdata/influxdb-observability . This receiver automatically detects schema at parse time.

Example: Metrics - prometheus-v1
