Is there a way to collect custom metrics (e.g. a /metrics endpoint serving metrics in Prometheus format) from docker containers? I'm currently running https://github.com/SumoLogic/sumologic-collector-docker but I can't seem to find a way to instruct it to collect metrics

Do I have to resort to using hosted collectors https://help.sumologic.com/03Send-Data/Sources/02Sources-for-Hosted-Collectors/HTTP-Source/Upload-Metrics-to-an-HTTP-Source

  Not currently through the installed Collector. Collecting Prometheus metrics will require a Hosted Collector and HTTP(S) Source and the following script.

  Hi Jacob,

  I note that a more recent check-in to the Docker collector does add support for Prometheus format See https://github.com/SumoLogic/sumologic-collector-docker/releases/tag/v19.227-19

  The installed collection method relies on a stream over TCP or UDP, with setup instructions detailed here: 

  https://help.sumologic.com/03Send-Data/Sources/01Sources-for-Installed-Collectors/Streaming-Metrics-Source#Configure_a_streaming_metrics_source

  If you're using JSON configuration and streaming over TCP port 2003 for example, the source might look something like this

  {
  "api.version":"v1",
  "source":{
  "name":"MySteamMetrics",
  "category":"metrics/prometheus/test",
  "automaticDateParsing":true,
  "multilineProcessingEnabled":false,
  "useAutolineMatching":false,
  "contentType":"Prometheus",
  "forceTimeZone":false,
  "filters":[],
  "cutoffTimestamp":0,
  "encoding":"UTF-8",
  "protocol":"TCP",
  "port":2003,
  "sourceType":"StreamingMetrics"
  }
  }
