I am blessed with a router that has the nasty habit of having a (AFAICT) random initial value for its counters when reset. This manifests itself as large spikes on my link speed graph (far above max physically possible). Is there a way of discarding erratic values in zabbix (like saying the maximum possible value for that key is X, so if a read is above that, discard that value as if the read was unsuccessful). MRTG had this option so I would be surprised if Zabbix did not have this.

It is not supported currently. -
Well, it would be nice to haveOriginally posted by Alexei
It is also useful when doing readouts of flaky sensors, or when f.e. a service doesn't handle 64bit numbers properly. Or simply when the service can't encode 'unavailable' and returns 0 (which cause problems just as 0 is not the same as NULL )

I agree, it has to be implemented at some point
