Table Panel along with Google Cloud Monitoring is failing to show data

Grafana Table Panel
,
1

Hello,

So this issue is around use of “Table” Panel along with “Google Cloud Monitoring” Datasource.

We’ve noticed that Table is unable to populate data if there’s only 1 record in the Metric. However, TimeSeries show us the event captured.

Table unable to populate Metric:

As soon as all the transformation is disabled - and chart is changed to Time Series we see a spike of data

When i debug into the individual Transformation “working” vs “non working”

In Working state: Input get’s transformed into “Metric”

Non Working state: It seems transformation is not getting applied on Input, As it does not convert to Metric - Output of Transformation is same as Input of Transformation

Can anyone suggest how we can fix this?

Hi @Rohan,

Thanks for opening this post.

I think that you might caught a bug but need to check it with my team.

Can you please provide the step-by-step instructions so that the community can also try to reproduce it on a test machine?

Thanks.

Hi @usman.ahmad,

Apologies for late response.

Step by Step Instructions will be as follows:

  1. Create a Log Based Metric in Google Cloud
  2. Generate 1 Log
  3. Create a Table in Grafana Datasource being Google Coud Monitoring and Metric will be that specific Log Based Metric.
  4. Apply Transformation - As soon as Series to Row is applied it simply does not detect any data.
  5. Confirming if Log is there? Change Transformation back to Time Series - you will see a Log being populated from Log Based Metric.

Hi @Rohan

I do not have used this plugin. However, on

play.grafana.com website, this plugin is available so you can reproduce it by creating a new dashboard.

One limitation is that you cannot save the dashboard. So I will propose that you try to reproduce it and share like screencast of it and paste it here.

This way I will duplicate it and will try to find more information if it a know issue or etc.
