Nagios Support Forum

Running XI 5.4.8 on CentOS instance in AWS.

I started to install cacti on our XI server (installed cacti and php-pear-Net-SNMP). I then added the cacti table to the DB. When I got to the SNMP configuration I saw that cacti does not support SNMPv3 (which is mandatory in our environment), so I uninstalled cacti and php-pear-Net-SNMP.

Since then most of the links on the CCM page do not work. The links in Quick Tools and a few in Tools work, but none of the links in Monitoring, Alerting, Templates, Commands, Advances, or CCM Admin work. When I click a dead link the page goes blank and it does not even seem like it is going out to get the page.

All the links on the other pages seems to be working (Home, Views, etc) , and I can see in the Home page that it is still monitoring all our hosts, but I cannot do any configuration.

When I cut and paste a non-working link from the menu (E.G.: Monitoring -> Services) I get the following error in the browser:
"This page isn’t working
REDACTED is currently unable to handle this request.
HTTP ERROR 500"

I need some help - I am not sure what to do to resolve this.

Do you still have the cacti configuration in the httpd config directory? This could be causing problems. Remove file and restart httpd I would also check to see if there is any info in the httpd error log

What is the name of the file to remove and where is it?

I went to /etc/httpd/conf.d/ and there is no cacti.conf file or anything similar.

That would be the one. Did you restart httpd after you removed it?

There was not cacti.conf file to remove - it was not there to begin with.

I did restart httpd.conf more than once.

I went back in and double-checked. There are no cacti files on my whole system.

I restarted httpd and nagios as well. There are no errors in the log file either.

I really need some help here. I cannot make any monitoring or alerting changes at all.

I wound up backing up my instance and re-installing Nagios, which resolved my problem. It is not the best solution, but you can close this out because I can't spend more time on it.

Was just going to ask for your httpd configs, but I'm glad you got it working form a backup.
