Graph time series data without collector

Good afternoon! I have a query to bring:

  • Value of a count of computers
  • Metric to group the computers in a Online/Offline state
  • Current time

Is there anyway I can graph the state of the computers over the time only using some sort of “snapshot” o “trigger” available in Grafana without having to collect the data in table over the time?

For example: The query executes every 15min. to graph the count in an entire day.

Thanks!

Grafana does not store data. It displays data from a back-end data store of
your choice:

You have to put the measurements you want to be displayed into one of those
data stores, otherwise Grafana has nothing to show.
