<![CDATA[Make missing data all zeros?]]>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

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.

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,
Victor
