Missing Data for some Data Sources

Bernett · Post by **Bernett** » Tue Mar 23, 2010 9:31 am

Hello together,

i have a strange behaviour in some graphs. They show only the data of the last 9 hours and all the data before are not visable (empty graph). I have checked the poller and it works fine. This behaviour does not occur in all of my graphs and i cannot find a relation between the broken graphs.

Hote someone can help me!

best regards

Bernd

please read/follow http://forums.cacti.net/viewtopic.php?t=11747

also a graph debug output would be useful.

Looks like you created your own templates? The end=-60 is the cause for the lack of displayed data.

Thanks for your fast reply. Can you please explain me where i can change this End=-60 setting and how it can causes this gaps in my graphs?

best regards

Check that graph template.

Also post an 'rrdtool info' on that 275.rrd file. It's possible your rrd settings are misconfigured.

I have checked the graph template, but i cannot find any misconfigurations. Can you please check my attached graph template?

best regards

I have check other devices which uses the same same graph template and there is no gap in the graph.

May it be a problem of the rra file?

Why are you using a perl script to retrieve windows cpu usage when it's already available via snmp? The cacti script snmp - processor does this for you much faster than perl ever will. then you use the aggregate plugin to put all of the cpus onto one graph.

Ok in the future i will change this from perl to the internal snmp feature, but this is not the reason why some of my graphs have gaps and others not, which are using the same graph template.

Can you explain me the reason for this gaps?

The data template you used is apparently set up for 1 min graphing and your graphs are for 5 min.
