RPI4 Monitoring, total bytes received

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

Grafana 8.3.3 on Raspbian 11

  • What are you trying to achieve?

Get a panel with total bytes received (in MB), for a monitoring dashboard of my RP4

  • How are you trying to achieve it?

SELECT mean(“bytes_recv”) FROM “net” WHERE time >= now() - 5m and time <= now() GROUP BY time(200ms) fill(null)

  • What happened?

Amount shown is not accurate

  • What did you expect to happen?

select bytes_recv from net limit 10
name: net
time bytes_recv

—> I assume 764987662 is the total number of bytes received. This translates into 764 MB, which i was expecting.
The value in the panel should be 764MB and not 70.5MB as shown.

see this screenshot:

in other words:

I’d like to have the last value of the series diesplayed as total MB.
