Prometheus remote write

The prometheusremotewrite data format converts metrics into the Prometheus protobuf exposition format.

Warning: When generating histogram and summary types, output may not be correct if the metric spans multiple batches. This issue can be somewhat, but not fully, mitigated by using outputs that support writing in "batch format". When using histogram and summary types, it is recommended to use only the prometheus_client output.

Configuration

[[outputs.http]]
  ## URL is the address to send metrics to
  url = "https://cortex/api/prom/push"

  ## Optional TLS Config
  tls_ca = "/etc/telegraf/ca.pem"
  tls_cert = "/etc/telegraf/cert.pem"
  tls_key = "/etc/telegraf/key.pem"

  ## Data format to output.
  data_format = "prometheusremotewrite"

  [outputs.http.headers]
     Content-Type = "application/x-protobuf"
     Content-Encoding = "snappy"
     X-Prometheus-Remote-Write-Version = "0.1.0"

Metrics

A Prometheus metric is created for each integer, float, boolean or unsigned field. Boolean values are converted to 1.0 for true and 0.0 for false.

The Prometheus metric names are produced by joining the measurement name with the field key. In the special case where the measurement name is prometheus it is not included in the final metric name.

Prometheus labels are produced for each tag.

Note: String fields are ignored and do not produce Prometheus metrics.
