# OpenTelemetry Input Plugin
|
||||
|
||||
This plugin receives traces, metrics and logs from
|
||||
[OpenTelemetry](https://opentelemetry.io) clients and agents via gRPC.
|
||||
|
||||
## Service Input <!-- @/docs/includes/service_input.md -->
|
||||
|
||||
This plugin is a service input. Normal plugins gather metrics determined by the
|
||||
interval setting. Service plugins start a service to listen and wait for
|
||||
metrics or events to occur. Service plugins have two key differences from
|
||||
normal plugins:
|
||||
|
||||
1. The global or plugin specific `interval` setting may not apply
|
||||
2. The CLI options of `--test`, `--test-wait`, and `--once` may not produce
|
||||
output for this plugin
|
||||
|
||||
## Global configuration options <!-- @/docs/includes/plugin_config.md -->
|
||||
|
||||
In addition to the plugin-specific configuration settings, plugins support
|
||||
additional global and plugin configuration settings. These settings are used to
|
||||
modify metrics, tags, and field or create aliases and configure ordering, etc.
|
||||
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.
|
||||
|
||||
[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins
|
||||
|
||||
## Configuration
|
||||
|
||||
```toml @sample.conf
|
||||
# Receive OpenTelemetry traces, metrics, and logs over gRPC
|
||||
[[inputs.opentelemetry]]
|
||||
## Override the default (0.0.0.0:4317) destination OpenTelemetry gRPC service
|
||||
## address:port
|
||||
# service_address = "0.0.0.0:4317"
|
||||
|
||||
## Override the default (5s) new connection timeout
|
||||
# timeout = "5s"
|
||||
|
||||
## gRPC Maximum Message Size
|
||||
# max_msg_size = "4MB"
|
||||
|
||||
## Override the default span attributes to be used as line protocol tags.
|
||||
## These are always included as tags:
|
||||
## - trace ID
|
||||
## - span ID
|
||||
## Common attributes can be found here:
|
||||
## - https://github.com/open-telemetry/opentelemetry-collector/tree/main/semconv
|
||||
# span_dimensions = ["service.name", "span.name"]
|
||||
|
||||
## Override the default log record attributes to be used as line protocol tags.
|
||||
## These are always included as tags, if available:
|
||||
## - trace ID
|
||||
## - span ID
|
||||
## Common attributes can be found here:
|
||||
## - https://github.com/open-telemetry/opentelemetry-collector/tree/main/semconv
|
||||
## When using InfluxDB for both logs and traces, be certain that log_record_dimensions
|
||||
## matches the span_dimensions value.
|
||||
# log_record_dimensions = ["service.name"]
|
||||
|
||||
## Override the default profile attributes to be used as line protocol tags.
|
||||
## These are always included as tags, if available:
|
||||
## - profile_id
|
||||
## - address
|
||||
## - sample
|
||||
## - sample_name
|
||||
## - sample_unit
|
||||
## - sample_type
|
||||
## - sample_type_unit
|
||||
## Common attributes can be found here:
|
||||
## - https://github.com/open-telemetry/opentelemetry-collector/tree/main/semconv
|
||||
# profile_dimensions = []
|
||||
|
||||
## Override the default (prometheus-v1) metrics schema.
|
||||
## Supports: "prometheus-v1", "prometheus-v2"
|
||||
## For more information about the alternatives, read the Prometheus input
|
||||
## plugin notes.
|
||||
# metrics_schema = "prometheus-v1"
|
||||
|
||||
## Optional TLS Config.
|
||||
## For advanced options: https://github.com/influxdata/telegraf/blob/v1.18.3/docs/TLS.md
|
||||
##
|
||||
## Set one or more allowed client CA certificate file names to
|
||||
## enable mutually authenticated TLS connections.
|
||||
# tls_allowed_cacerts = ["/etc/telegraf/clientca.pem"]
|
||||
## Add service certificate and key.
|
||||
# tls_cert = "/etc/telegraf/cert.pem"
|
||||
# tls_key = "/etc/telegraf/key.pem"
|
||||
```
|
||||
|
||||
### Schema
|
||||
|
||||
The OpenTelemetry->InfluxDB conversion [schema][1] and [implementation][2] are
|
||||
hosted at <https://github.com/influxdata/influxdb-observability> .
|
||||
|
||||
Spans are stored in measurement `spans`.
|
||||
Logs are stored in measurement `logs`.
|
||||
|
||||
For metrics, two output schemata exist. Metrics received with
|
||||
`metrics_schema=prometheus-v1` are assigned measurement from the OTel field
|
||||
`Metric.name`. Metrics received with `metrics_schema=prometheus-v2` are stored
|
||||
in measurement `prometheus`.
|
||||
|
||||
Also see the OpenTelemetry output plugin for Telegraf.
