slok/go-http-metrics latency

Latency plugin for slok/go-http-metrics.

Uses the HTTP response histogram to measure the events as good or bad. It counts as error events that don't fall in the provided bucket.

For example if the bucket is 0.25, We will measure as an error, the requests that fall in the buckets greater than 0.25, in other words, that took longer than 250ms .

Options

  • bucket: (Required) The max latency allowed histogram bucket.
  • filter: (Required) A prometheus filter string using concatenated labels (e.g: exported_service="alertmanager-api",service="alertgram")
  • exclude_errors: (Optional) Boolean that will exclude errored requests from valid events when measuring latency requests.
