Host Status not Updating

[jwessels]

Hi Support,

I have the following problem; none of the host checks are updating and are stuck on the 1 May. There are no active checks in the queue or in the

I am receiving alerts via email and can see the checks in /var/log/messages, but not in the event log.

Thank you!

Can you Click Admin > Monitoring Engine Status and make sure Active Checks are enabled?
Can you provide a screen shot that too?

Hi,

As requested here is the screen shot, everything is running

Can you tail the last 40 or so lines of /usr/local/nagios/var/nagios.log and show us that?

Here is the last 40 lines

It looks like your ndomod connection may be broken - it's possible that your nagios user expired. Please check the age of the 'nagios' user to ensure that's not the case:

Code: Select all

chage -l nagios

Otherwise, we'll want to turn on ndo2db debugging and restart ndo2db:

Code: Select all

sed -i 's/debug_level=0/debug_level=-1/g' /usr/local/nagios/etc/ndo2db.cfg

Code: Select all

service ndo2db restart

Check on the logs we've enabled:

Code: Select all

tail -n50 /usr/local/nagios/var/ndo2db.debug

Code: Select all

head /usr/local/nagios/var/ndo2db.debug

Here is the output;
password seems fine but,

Code: Select all

[root@tsamarnagios ~]# chage -l nagios

ndo2db seems a bit broken

Code: Select all

[root@tsamarnagios ~]# service ndo2db restart
ndo2db was not running... could not stop
Starting ndo2db:Could not bind socket: Address already in use
 done.
[root@tsamarnagios ~]# service ndo2db status
