Nagios and Cacti troubleshooting considerations

I. Precautions for Naigos restart

1. Check the configuration file integrity before restarting the nagios Service (perform web page synchronization)

2. Pay attention to the Operation Sequence During master-slave synchronization. Do not worry about the operation sequence. Check the alarm mechanism (enable or disable notification)

3. Check whether the pnp4nagios process is enabled. If an exception occurs

3.1 check whether the ll/usr/local/nagios/var/rw/nagios. cmd permission is 777 if not modified

3.2 chmod 777 nagios. cmd

3.3 manually enable/etc/init. d/npcd start (small Sun flow chart)

3.4 restart httpd/etc/init. d/httpd restart

3.5 manual web page enabling detection time

4. After the device restarts, check whether the nagios process is normal, if an exception occurs, manually enable the nagios process/usr/local/nagios/bin/nagios-d/usr/local/nagios/etc/nagios. cfg

Ii. Cacti follows up on handling alarms

1. View logs and view a large number of alarms. Use commands to clear memory.
