Nagios Support Forum

centos 6, 2011R1.7

In my performance graphs, I only see data from several weeks ago. Unlike some others, the graphs do show up. Unfortunately, they are blank

in nagios/share/perfdata/ I see all folders for all my hosts. Within those hosts, I see the xml and rrd files

in /var/lib/mrtg/ I only see mrtg.ok, the perms on that folder are 775 apache:nagios

Here is some strange output that I see in npcd.log

any ideas?

This might be a permissions issue, can you run the following procedure and see if it resolves the issue:

There will be some missing files and error output from this script, which is normal.
http://library.nagios.com/library/produ ... -nagios-xi

I ran that script before and it broke everything. Took me three days to fix.

for instance, that script sets numerous directory to use the group "users", a group which has no members. Please keep in mind that I am running the VM that you guys provided, which makes it even stranger.

Please let me know why it sets the group to "users"

fao,

We've had a bit of problem with this, but I do believe I have a quick and comprehensive fix for you. First lets make sure that the problem is what I think it is. In the following example <rrd file> is some rrd file that you know to exist (preferably one from the /var/lib/mrtg/ directory. Type of the following:
That should return a completely clean value. If it says ANYTHING about errors, then that is definitely the issue. Thankfully, the fix is simple:

hey mguthrie, you are correct that the package 'bc' was missing

I installed it 2 hours ago then restarted nagiosxi, nagios, and npcd

Unfortunately, I still see nothing in the /var/lib/mrtg folder

[root@nagios ~]# ls -al /var/lib/mrtg/
total 8
drwxrwxr-x. 2 apache nagios 4096 Aug 29 15:25 .
drwxr-xr-x. 24 root root 4096 Oct 19 10:45 ..
-rw-r--r--. 1 apache nagios 0 Oct 21 17:00 mrtg.ok

nothing there unfortunately

i look at npcd.log and I see a lot of this

But it is writable and does exist

Any ideas?

Your /var/lib/mrtg/ should be owned and grouped with root.

chown root.root /var/lib/mrtg -R

The ownership on the stats directory should be nagios.nagios,

What are the permissions in your nagios/share/spool/perfdata ?

tks

I do not have a share/spool/perfdata directory. Should I?

the permissions on nagios/var/spool/perfdata are apache.nagios

w/in the perfdata/

some file have the permission nagios.users and others nagios.nagios

I still don't understand why the "users" group keeps popping up when no one belongs to that group.

here is most recent output of npcd.log

alright, now I am getting some basic graphs

chmod -R g+x nagios/share/perfdata

seems to have done the trick

Ok, thanks for the update!
