Preview of values (shows max 20)

I have a template which is used to query all the interfaces of a device . But from the grafana i can only see max 20 interfaces,how should i do to obtain all the interfaces

Use the drop down below the dashboard, the variable value selection drop down that you see below the dashboard top navigation(when not in template edit mode)

Correct , i can see all the interfaces now , but it seems that the data is incomplete

you can see that this device has G1/0/25 and G1/0/26 , but i can not find them on the dashboard

Depending in the datasource there is a limit of 1000 items

Hi, I’m new to Grafana and trying to figure out how to show variable values in the dropdown. Basically, trying to do the same thing above (Preview of Values) but not sure how to do it. I’m running Grafana 6.0.0 Beta Version.

I don’t know the answer to your question but have to ask why you are running the Beta version of an old version. The current release is 6.1.6.
