[mrtg] data whel poll is not available

[Steve Shipway]

If the polling fails, then MRTG will get a Unknown value.

 

In MRTG, Unknown is displayed as the previous value.  If you have ‘unknaszero’ option, then it is displayed as zero.

 

If you are using Routers2/RRDTool/MRTG, then Unknown is displayed as a grey bar.  Use ‘unknaszero’ to display unknowns as zero, and ‘unknasprev’ to display unknowns as the previous value (as in native MRTG).

 

You will normally be polling every 5 minutes, and so you would need to refresh your graph every 5 minutes to see the changes.

The unknaszero value show me the last value and if is equal  as example a number of phones registered into the callmanager that remain equal … I think is necessary to have a refresh every example 5 minutes for update the last value.

How I can solve it ?

 

Thank you

Hi Guys, 

 

A quick question, 

 

When I poll a Memory into a cisco router  I receive a correct value , but if there are issues on polling the graph show me always the last value obtained (Iand I can’t understand if there are some problem) , how can I show on the graph a “zero” value based on an error of polling device ?

 

Thank you

 

Massimo
