Do you have root access to the server?
If so, can you run these commands to stop the processes if they are running, remove the lock files and start them up again.

Code: Select all

service nagios stop
service ndo2db stop
rm -rf /usr/local/nagios/var/rw/nagios.cmd
rm -rf /usr/local/nagios/var/nagios.lock
rm -rf /usr/local/nagios/var/ndo.sock
rm -rf /usr/local/nagios/var/ndo2db.lock
service ndo2db start
service nagios start
Then check the status of ndo2db and nagios to see if they are running.

yes, we have access to root and you want to restart the service using root user or nagios?

[HTTP ERROR 500]

Have you tried these KB articles?
https://support.nagios.com/kb/article.php?id=25
https://support.nagios.com/kb/article/n ... n-481.html

A few months ago on one of our customer's SourceGuardian was broken. It was quite hard to find out, but what helped was browsing directly to https://xiserver.fqdn/nagiosxi/login.php and only then Apache error logging was filled with an error that lead to SourceGuardian
[Tue Aug 07 14:00:38 2018] [error] [client 10.0.01] PHP Fatal error: SourceGuardian Loader - Protected script's header is broken. Probably the encoded file was modified. Please install an original unmodified file or contact the author of the script to get the original file. Error code [10] in /usr/local/nagiosxi/html/login.php on line 2
In our case it was solved by running the SourceGuardian step that fullinstall normally invokes. Then error 500 finally disappeared.

First, lets see why Nagios is not running by running a verification.
Run all of the commands as root.

Run this for the verification

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
If you see a configuration error, that is stopping it from running and it will have to be resolved.
FYI, the nagios process creates the nagios.cmd file. If nagios is not running, it will not exist.

Next, run this to restart Apache

Code: Select all

service httpd restart
Then run this tail command to view the Apache error logs.

Code: Select all

tail -f /var/log/httpd/*_log
Then try to login to the XI GUI and post any errors that you see in the screen running the tail command.

Also, get these files from the server and post them here.

Code: Select all

/etc/init.d/nagios
/usr/local/nagios/etc/nagios.cfg

Re: Prerequisites for check_oracle_health plugins

Post by tgriep »

The nagios.lock file location is not pointing to the same location in the init script and the nagios.cfg file and that is causing the wrong nagios status.

Edit the /usr/local/nagios/etc/nagiuos.cfg file and change this line from

Code: Select all

lock_file=/usr/local/nagios/var/nagios.lock
to

Code: Select all

lock_file=/var/run/nagios.lock
Restart nagios by running

Code: Select all

service nagios restart

The Apache errors look like it could be a permission issue or a misconfiguration in the Apache config files.
Can you run the following commands as root and post the /tmp/info.txt time to the ticket?

Code: Select all

ls -lR /usr/local/nagiosxi >/tmp/info.txt
cat /etc/httpd/conf.d/nagiosxi.conf >>/tmp/info.txt
cat /etc/httpd/conf.d/ssl.conf >>/tmp/info.txt
