Hi, I left my Nagios XI unattended while i was on leave, came back and it had several issues. The disk was full and somebody had done a dirty reboot on it. I increased to disk size and repaired the database and it was up and running again.

I have just noticed that my host graphs have stopped updating. The graphs do display but they are not updating. I *think* that ncpd is responsible for this and have check that it is running, restarted it anyway, what else might it be?

I'm using Nagios XI 2012R2.8c

I checked npcd.cfg, it has not been modified since Jan 2014. The graphs stopped updating at the end of Feb 2015.

Anyone got any ideas what might be causing this?

Thanks

Matt

Update

I just found this on the forum which seemed appropriate

Code: Select all

service npcd stop

cd /usr/local/nagios/var/spool/xidpe

find . -type f -delete

service npcd start

It seems to be collecting data and graphing with it now, i will keep an eye on it but needless to say, i have had to delete all of my historic perf data which is a shame but never mind.

I believe that this has now fixed my issue. I hope that it helps someone else in future.

Sorry for not getting to you sooner - we start right around the time your posted your last post. Glad it worked out for you though!

I'll be closing this thread now, but feel free to open another if you need anything in the future!
