How to remove unnecessary dashboards at "status panel"

We build heatmap status panel to monitor 200 servers. But we are having some servers, which it won’t send the data.
Those are unwanted servers for us. How to remove those panels?.
In below image, we are showing the unwanted servers, which doesn’t show any data.

Thank you…

You have to remove them from your tsdb, or filter them out in the variable query

Hi @torkel

Can you please advise me, how to filter them out in the variable query with an example ?.

Thank you…

Most datasources do not support that, what datasource are you using?

I am using InfluxDB datasource.

Influxdb metric exploration query api does not support removing tag values based on no data present

Is any other way to achieve this? or else should we need to delete some panels manually ?.
