Tactical Overview, Ops Center, Ops Screen Problems

I'm not exactly sure when this started, but it seems like the following screens aren't updating on my system:
Tactical Overview
Operations Center
Operations Screen
When I click directly on Tactical Overview, I get the "Whoops! Error: Could not read object configuration data!" screen. However, I have my home link set to go to the tactical over view screen and I can get to it that way successfully.
Any help would be appreciated.

Have you recently added a ram disk?
Can you output
Code: Select all
cat /usr/local/nagios/etc/nagios.cfg |grep object_cache_file
and then get permissions of the file is shows
Code: Select all
/usr/local/nagios/var/objects.cache
also, is nagios running

I went back through the document for implementing a ram disk as your post gave me somewhere to look. When I check fstab, I see the following:
Code: Select all
/dev/VolGroup00/LogVol00_ROOT / ext3 defaults 1 1
/dev/VolGroup00/LogVol00 /tmp ext3 defaults 1 2
/dev/VolGroup00/LogVol00_VAR /var ext3 defaults 1 2
LABEL=/boot /boot ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
tmpfs /var/nagiosramdisk tmpfs defaults,size=75m 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
/dev/VolGroup00/LogVol01_SWAP swap swap defaults 0 0
10.100.3.220:/kickstart /kickstart nfs defaults 1 2
Would having multiple temp file systems be getting in the way?
I did find that the commands were missing, per the document. I made that change and now I can actually get to the tactical overview screen, however, it's not the right one. It's almost like it's pointing to an old version of it. If I click on the home link and it takes me to the tactical overview screen I have set for it to go to, it is updated and correct.

What does it need to be set to?
Code: Select all
-bash: /var/nagiosramdisk/objects.cache: Permission denied
Code: Select all
-rw-r--r-- 1 nagios nagios 6368693 Feb 26 19:25 objects.cache

How's the free space on that RAM disk?

I came in this am to the following:
Code: Select all
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00_ROOT
48G 28G 18G 61% /

tmpfs 2.0G 0 2.0G 0% /dev/shm
tmpfs 75M 75M 0 100% /var/nagiosramdisk
I'm assuming I need to resize the ramdisk...

Yes, but also check why it was filled up. If you're also using it for the perfdata and checkresult spool, those files can fill up the RAM disk if either the Nagios daemon or NPCD daemon aren't running.
