OpenTelemetry Output Plugin
This plugin sends metrics to OpenTelemetry servers
and agents via gRPC.
Configuration
# Send OpenTelemetry metrics over gRPC
[[outputs.opentelemetry]]
## Override the default (localhost:4317) OpenTelemetry gRPC service
## address:port
# service_address = "localhost:4317"
## Override the default (5s) request timeout
# timeout = "5s"
## Optional TLS Config.
##
## Root certificates for verifying server certificates encoded in PEM format.
# tls_ca = "/etc/telegraf/ca.pem"
## The public and private keypairs for the client encoded in PEM format.
## May contain intermediate certificates.
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Use TLS, but skip TLS chain and host verification.
# insecure_skip_verify = false
## Send the specified TLS server name via SNI.
# tls_server_name = "foo.example.com"
## Override the default (gzip) compression used to send data.
## Supports: "gzip", "none"
# compression = "gzip"
## Additional OpenTelemetry resource attributes
# [outputs.opentelemetry.attributes]
# "service.name" = "demo"
## Additional gRPC request metadata
# [outputs.opentelemetry.headers]
# key1 = "value1"
Schema
The InfluxDB->OpenTelemetry conversion schema and implementation are
hosted on GitHub.
For metrics, two input schemata exist. Line protocol with measurement name
prometheus
is assumed to have a schema matching Prometheus input
plugin when metric_version = 2
. Line
protocol with other measurement names is assumed to have schema matching
Prometheus input plugin when
metric_version = 1
. If both schema assumptions fail, then the line protocol
data is interpreted as:
- Metric type = gauge (or counter, if indicated by the input plugin)
- Metric name =
[measurement]_[field key]
- Metric value = line protocol field value, cast to float
- Metric labels = line protocol tags
