Merge transformation

  • What Grafana version and what operating system are you using?

  • What are you trying to achieve?
    i am trying to use the merge transformation or outer join transformation to join 12 query results in a table. some of the queries is not returning any data. so the entire table is blank even though some of the queries have data. I am trying to figure it out what else I can do to get the data displayed

  • How are you trying to achieve it?
    query 1 - results in table
    query 2 - results in table
    query 3 - results in table

Merge transformation on common field, outerjoin on common field

  • What happened?
    displaying bad gateway

  • What did you expect to happen?

  • Can you copy/paste the configuration(s) that you are having problems with?

  • Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.

  • Did you follow any online instructions? If so, what is the URL?

it is solved, the queries taking longer time and data source post method was able to fix my issue.
