I wonder if it is a ndo issue... Run the following commands:

Code: Select all

service nagios stop
killall -9 nagios
service ndo2db stop
service ndo2db start
service nagios start

Let us know if this fixed your problem.

I think the problem resides here:

'/usr/local/nagios/bin/ndomod.o' -> /tmp/nebmodVyRc5h

Is there anyway to change this to load to /export/tmp ?

[lmiltchev]

Run the following command:

Code: Select all

chmod 777 /tmp

then restart the services again:

Code: Select all

service nagios stop
service ndo2db stop
service ndo2db start
service nagios start

[Keo]

Our CIS standards wont let things be execute from /tmp. Is there anyway to have this written to another directory and ran from there?

[abrist]

It is actually nagios that is doing it. In fact, all processes fired off by nagios will do that. You can change the default location for the temp directory in:

Code: Select all

/usr/local/nagios/etc/nagios.cfg

Change:

Code: Select all

temp_path=/tmp

To:

Code: Select all

temp_path=/export/tmp

(or where ever you want)
EDIT: Don't forget to restart nagios afterwards:

Code: Select all

service nagios restart

This resolved my problem. I have other issues, but I will open a different thread for those. Thanks for your help
