Use of templating variables in grafana with ntop datasource

[simonemainardi]

Hi,

I've been triying to use variables to have templating dashboard to be able to visualize ntop graphs for different hosts, but i have notice that i can not use variables in the metrics when configuring the panel graph in grafana with ntop datasource.. so i would like to know if it is possible to use templating variables when using grafana with ntop datasource (create a different graph panel for each host will take me so much time).

Thanks.

Hi, Daniel from the Grafana team here.

For the dropdown, you have to allow custom text - the backend looks like it doing template variable substitution already. If custom text is not enabled, then the user is not able to write a template variable ($ntophots in this case) in to the input field.

You just need to add allow-custom="true" to:

Here is an example: https://github.com/grafana/azure-monitor-datasource/blob/master/src/partials/query.editor.html#L28

How exactly did you get all these hosts in one diagram?
I can't even see all hosts that are visible in ntopng let alone get all hosts into one diagram :/
