Hellow everyone. I'm wondering if in dashboards I can use the variables for PromQL?

Yes, it would be something like this

{service_name="{{.service_name}}"}

I've defined a uri value "/klt/api/v1/transactions" and tried to use it in PromQL like this:

sum(rate(http_server_requests_seconds_count{uri=~{{.uri}}}[1m]))

And I'm getting the error:

Error: API responded with 400 - encountered multiple errors: error in query-A: parse error at char 50: unexpected character inside braces: '/'

I understand that is because the the var needs to be inside "". So no the question is how can I escape the quotes? I've tried

\"

You don’t need to escape the quotes around the variable. Doesn’t this work for you ``sum(rate(http_server_requests_seconds_count{uri=~"{{.uri}}"}[1m]))``?

No:

No Data

But there is data, If I put "/klt/api/v1/transactions" I get results

Did you select the variable with the value? If you don’t make a selection from the dropdown current state will be none, and no results are shown.

@Srikanth Chekuri not sure I understand you. Where should I select the value. In the PromQL I only have a textfield for the query

Save the query and then go to the dashboard and make sure the variable has the value

/klt/api/v1/transactions

Query saved...

It doesn’t require a browser refresh. Did you try the refresh button at the top right?
