traces to logs integration

Open hagen1778 opened this issue 9 months ago • 7 comments

Grafana Tempo supports Traces to Logs integration between Tempo datasource and limited list of logs datasources:

  • 'loki',
  • 'elasticsearch',
  • 'grafana-splunk-datasource', // external
  • 'grafana-opensearch-datasource', // external
  • 'grafana-falconlogscale-datasource', // external
  • 'googlecloud-logging-datasource', // external

It would be great to check if VictoriaLogs could fit the requirements for such an integration and file a PullRequest to Grafana to support VictoriaLogs as one of the available backends.

@hagen1778 @Loori-R There two place, that we need to modify, to get it works. Datasource config, as mentioned in Issue, and one some "smelling" piece of code here Probably, they will not accept any PR for this, without refactor SpanLinks mechanics

I experimented with this, for local grafana installation, and get it works, but... It's realy smells

Seems to me like it'd be worth a try! This would be a really great feature. 🤞

p.s.: Im terrible at writing queries for VictoriaLogs, so the formatting of the tags may not be correct

@090809 Do you mind trying to open a PR on grafana?

@archef2000 I assume it needs more work. Unit tests and such

Quick update: we're waiting for a new Grafana release that will include this integration. Once it is out and everything is working fine - we'll be closing this issue.
