Clickhouse Alert error

I have a problem with using Grafana Alerts from Clickhouse.

  1. The requests to Clickhouse are working
  2. The metrics and graphs are working.
  3. The Alerts for Grapite’s data are working

…but when i wanna use Alerts for Clickhouse of dashboards with Timeseries metrics it not working.

Test rule:

conditionEvals:" = true"
error:“tsdb.HandleRequest() error rpc error: code = Unknown desc = … net/http: invalid header field name “””

And the same Execution Error in Alert rules.

Query inspector working correctly and when i use curl with that request i get an right data.

Whats wrong?

Grafana v7.2.0
plugin: ClickHouse (By Vertamedia) - 2.2.3 (latest)

Hi @tuxandr

You should have a much better chance of completing your goal with the new Unified Alerting in Grafana 8, which shipped today.

It’s an entirely new alerting platform with much greater power and ease-of-use. And it includes much greater support for variables in alerts

Check it out, and let us know if your issue persists:

docker run -p 3000:3000 --name=grafana -e "GF_FEATURE_TOGGLES_ENABLE=ngalert" grafana/grafana:8.0.0
