How to handle offline nodes that are occassionally online

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


  • What are you trying to achieve?

I have a couple of hosts that, due to mobility, are often offline but once in range are online. I would like to capture metrics (CPU, memory usage) and then be able to visualise them in grafana.

  • How are you trying to achieve it?

Unfortunately I do not know. I’ve looked online and see references to backfilling - but dont know if this is appropriate or even how it is done - as I havent been able to locate an example. Although this isnt a grafana issue I am seeking information about how it can be done.

If this is not an appropriate question to ask this forum then I apologise.

  • What happened?

  • 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?

How is the data from these host scrapped?
