Well this is a weird one. I just got word that our performance graphs arent graphing. All of them. I checked my dashboard and sure enough, I have graphs...they are there....but there is no data. Checked the "week" view on several graphs and the graphs drop off after midnight on 5/2! No changes that Im aware of tho I did add some monitoring users around then. Could my logs be full????? I checked drive space and that looks ok. Not sure what else would cause something like this. Lot of posts about missing graphs that didnt seem to pertain to this one. Please advise.............

Lets try restarting your graphing service.

service npcd restart

Also, if your CPU load exceeds 10.0, the graphing service will also stop until CPU load goes down.

Definitely not CPU as it has been like this for 6 days apparently and I have no warnings for anything that high. As for the command, executed it and it did say that NPCD was NOT running and was started. Ill give that a few minutes and see if that does it. What service is that???

npcd is the daemon underneath that processes performance data. The Admin->System Component Status (dashlet) has indicators for each of the subsystem processes. It should indicate of any of the processes underneath are having problems. You can also restart the graphing service from this dashlet.

Graphs are still empty.....

Just to clarify, you ARE seeing graphs, but they have no data in them, correct?


If this issue showed up after an update, see below:


Here's an issue on our wiki that some people have reported that may fix your issue.

* Some users reported that editing the following lines in their /usr/local/nagios/etc/nagios.cfg file fixed their graphing issues:

I DO see graphs...they just do not contain data. I was reluctant to try some of those other issues as they seemed to pertain to the "red x" missing graphs completely. Should I still try the above?

Per the link I tried the update credentials in admin. Restarted service and up came the graphs! We would this just stop working at 1AM????? Easy enough to fix I guess.............

OK, good deal. Our next release has a revised way in which we generate the graphs, and it should eliminate a large number of the issues we have with them, particularly related to permissions.

Cool! Thanks again! You guys are right on top of this stuff!
