Nagios Support Forum

Hello Raj,

Have you taken a look at this thread? Since you and David.adder had the same issue with rrd's, and then he had a problem with graphs not showing up I thought they may be similar:

Hi,

I have tried the http://assets.nagios.com/downloads/nagi ... ios_XI.pdf steps, i have resolved the rrd does not exist issue. however, i couldnt see the performance graphs on router/switches and other devices. Rest of windows machines and linux machines are showing properly..
i ran the below command found that it was updated on 8th jan 2013, is there any issue on fetching data?? i'm bit confused..

let me know if you need further..
thanks!!

Can you post your process_perfdata.cfg file?
Also for good measure run the following:

Hi,

Please find below npcd.cfg, perfdata.log and npcd.log file for your reference.

After performing the below steps, still the problem persists.
service npcd stop

killall -9 npcd

Please run the following and report back. Also, lets temporarily turn on debug log level in /usr/local/nagios/etc/pnp/process_perfdata.cfg Then wait just a minute and run

After a long exertion, we have finally found out the solution for this.. please find below steps to clear it out..

1. Root cause for this issue might be time, i dont know how this time got changed and not reflected. I have updated the time sync..
2. /usr/local/nagios/share/perfdata/ -- you need to look to those file with time stamps, i can see it was all incorrect time/date.In this location, rrd files are getting stored and accessed. Due to which, we are not able to get the Performance graph properly.

3. i have manually cleared those rrd files which has incorrect date/time, after that it started created newly with current time stamps. After that i can see the performance graphs... Wow thats great!!! hope it will give you some idea...

Regards,
Raj.

This was mentioned that you could do this before in this thread:

How important is the historical information on your installation? I ask because by far the easiest way to remedy the situation would be to delete the old .rrd files and let new ones be created.

Glad to hear it all worked out for you though. It seems like yours and David.Adder's cases were both from the same root cause, a change in time as if the system were in the future then you yanked it back to the current time.
