Nagios Support Forum

I'm wondering if it might be ok to simply call the command without arguments. I just added this to nrpe.cfg: command[check_disk]=/usr/lib/nagios/plugins/check_disk / On the problem hosts and, now, I'm seeing what's shown in the attached screen-shot. So, transform-staging is the only problem machine ...

I believe I'm getting a clearer sense of how things work. Thanks. Working with a few more services will likely get me to where I'm good on it all. The main problem that I'm seeing, now, is that the line in the attached screen-shot is showing for the monitored host that I'm currently focusing on. Whe...

This is VERY confusing. It looks to me like all the commands are getting defined in /etc/nagios3/conf.d/commands.cfg. Beyond the code that I've added to that file for check_disk, do I also need to add the command[check_disk]=/usr/lib64/nagios/plugins/check_disk $ARG1$ to /etc/nagios/nrpe.cfg? That's...

Oh, I saw your comment after I posted that edit to my last... [root@ip-10-160-23-32 ~]# /usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p / DISK OK - free space: / 5204 MB (65% inode=79%);| /=2777MB;6450;7256;0;8063 So, I just started looking around in /etc/nagios3/conf.d, on the Nagios server. ...

I get:

[nagios@ip-10-160-23-32 ~]$ /usr/lib64/nagios/plugins/check_disk !-w 20% -c 10% -p /
/usr/lib64/nagios/plugins/check_disk which ohai 20% -c 10% -p /
DISK CRITICAL - which is not accessible: No such file or directory

But,

[root@ip-10-160-23-32 ~]# which ohai
/usr/bin/ohai

Yeah, from portal-production (the monitored node), I get: [root@ip-10-160-23-32 ~]# netstat -na | grep 5666 tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN tcp 0 0 :::5666 And from the Nagios server, I get: root@ip-10-244-20-90:~# /usr/lib/nagios/plugins/check_nrpe -H 50.18.168.192 NRPE v2.15

After looking over your last post, I ran this, on the Nagios server: root@ip-10-244-20-90:/etc# grep -R check_nrpe * nagios3/conf.d/commands.cfg: command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c check_nagios -t 20 nagios3/conf.d/commands.cfg: command_name check_nrpe_alive nagios3/conf.d/commands....

No, the only change that I've made, in about 6 months is to add the apt-if-appropriate code, for installing apt only on Debian/Ubuntu VMs. Do you happen to know what steps I would need to follow to get the check_disk command setup? If I can just get that down to a manual process, I'll be able to add...

Yeah, it really looks like something must have changed, but I'm the only person in our organization who knows anything about Chef and it's been many months since I last did an upload of any kind. "portal-production" is a node that's showing the "NRPE: Command 'check_disk' not defined&...

Ok, but I'm not able to determine, from the replies that I've seen on the forum, so far, what my next steps need to be, precisely. I know of no way that changes would have been made to the setup on any of these hosts. Yet, suddenly, a few weeks ago, bogus alerts started coming out related to the &qu...
