Re: Missing percentdiscards, percenterrors, discards, and errors graphs

Hi,

I also have problems with some of the graphs, looks like a problem with the
visualization backend, because the same counters graph without errors in
Grafana. Also the same counters in OpenNMS sometimes graph sometimes not.
Its strange.

Best regards,

Jose
