Nagios Support Forum

For those who read this... Apparently there is a REGULAR EXPRESSION MATCHING value in nagios.cfg I have just changed use_regexp_matching=1 to use_regexp_matching=0 And it now seems to be working. This is very frustrating when the values host_name values do NOT match, so the matching should not need ...

The only other reference for generic-host I can find is in
/usr/local/nagios/etc/objects/templates.cfg and /usr/local/nagios/etc/config/templates.cfg

# Linux host definition template - This is NOT a real host, just a template! define host{ name linux-server ; The name of this host template use generic-host ; This template inherits other values from the generic-host template check_period 24x7 ; By default, Linux hosts are checked round the clock ...

This has not been resolved as there is obviously a bug/flaw where it ignores the host_name field in the .cfg files. The only 'fix' that I can get to work is by removing .host.name from the host_name field. I should be able to use the full name of 'web-backups.host.name' and 'monitor.host.name' witho...

Don't lock the thread as it is NOT resolved!

I have one host group: define hostgroup{ hostgroup_name Servers - Linux members centos,host.name,monitor.host.name,web-backups.host.name, (plus a few other non related servers) } The only other references to linux-server are in the default /config/templates.cfg and /objects/templates.cfg files. It d...

Sure... [user@centos ~]# grep -R monitor.host.name /usr/local/nagios/etc/ /usr/local/nagios/etc/config/web-monitor.cfg: host_name monitor.host.name /usr/local/nagios/etc/config/web-monitor.cfg: host_name monitor.host.name /usr/local/nagios/etc/config/web-monitor.cfg: host_name monitor.host.name /usr...

When I change the host_names back to monitor.host.name and web-backups.host.name I get the warning back in /usr/local/nagios/var/nagios.log. [1570539439] Warning: Duplicate definition found for service 'Uptime' on host 'monitor.host.name' (config file '/usr/local/nagios/etc/config/web-website.cfg', ...

Figured it out. Badly written software... My new host's host_name was web-backups.host.name running Ubuntu. I had another host called monitor.host.name running CentOS plus another call just host.name, also on CentOS. It appears Nagios ignores anything before host.name so the results I was being show...
