Hello all,

We have a lot of nodes that flap on SNMP availability due to routing issues. However, graphs can be deceiving as they simply replace any empty zones with a line connecting the two pieces of "real" data on either side.

Is there a good way to replace lost data with zeros, -1's, anything to make it obvious that it's an outage? I was thinking at worst I could add a transformation script, but something smarter would be preferred.

Thanks,
Zach

Hi,

currently it's possible only by replacing normal DCIs with script DCIs (script DCI call SNMPGet and on failure returns something to indicate a failure). I'll add feature request to make this functionality simpler.

Best regards,

Just happen to have implemented some monitoring where the graphs "connecting the dots" as described is an issue as well.
Being able to store a NULL value in case of an error in collection or a node not being available and having the system actually show a gap in a graph based on that would indeed be nice.
