Troubleshooting Signoz Dashboard Metrics and Custom Dashboard

TLDR Div reported issues with the Signoz dashboard, including external call error percentage and a negative operation count. Ankit and Srikanth provided solutions, including upgrading to v0.17.0 and using a custom WHERE clause for the desired service suffix.

Hi Team, we recently pushed Signoz to our production services (was in closed testing) :tada: , getting these metrics in the dashboard, the External call Error percentage is looking like this, also the name to which external call is not mentioned, what to make with this data ?

Div the repeated `External Call Error Percentage` in labels is fixed in v0.17.0 release. There are too many lines because of which the 1 day chart looks like this. Can you upgrade and share screenshot of 1 hr interval?

I am guessing some UI/UX improvements might be helpful

He hasn’t updated I believe. Div when you update to `0.17.0` you will see the which external address has how much error percentage.

another issue I noticed in the dasboard in 1 of the service, the operation count reached to `-10000` , what could be the reason for negative value ?

This is known issue and it happens because of the collector restart. We are fixing this.

Srikanth Thanks, last query of the day :slightly_smiling_face: I am creating custom dashboard in Signoz, where I have service name with suffix as. `service-name:prod`,`service-name:staging` ,`service-name:dev` what should I write in the `WHERE` clause to have services with only `prod` suffix
