Hello, On my Nagios web interface I'm getting NRPE: Command 'check_procs' not defined for Total Processes. Current Load, Current Users, and Pings are working and being displayed correctly. Nagios host is running CentOS 7. From Nagios host I can enter /usr/lib64/nagios/plugins/check_procs -w 150 -c 2...

Ubuntu host is up. Not exactly sure what I did but I do remember entering sudo /etc/init.d/nagios-nrpe-server restart and then going to Nagios server and entering check_nrpe -H Ubuntu-IP-Address and received output NRPE v2.15. I then looked at Nagios web interface and Ubunut is working. Thank you @c...

When I login to Ubuntu nrpe server. There is no directory for /usr/local/nagios/libexec . If I go to /usr/lib/nagios/plugins I do see many check_xxxx commands but not check_nrpe!

Thank you for your time and assistance @cdienger.

Hi,

I ran nmap command and Ubuntu port 5666 does appear to be open. I attached pic.

I wonder what is causing this issue. My Windows machines are being monitored but none of my Linux servers aren't working. Then again nrpe isn't installed on Windows servers. I'm using NSCLient for Windows.

Hi @cdienger, The way I installed nrpe agent from nagios server I entered yum --enablerepo=epel -y install nagios-plugins-nrpe . In the past I've installed nrpe agent in this way and it has worked with no issues. If nrpe is the reason why nagios monitroing service is not working then I will uninstal...

I installed Nagios core 4.4.3 on Centos 7. I used yum --enablerepo=epel to install Nagios and Nagios plugins. On target host Ubuntu, I installed nrpe and nagios-plugins. On Ubuntu host nrpe.cfg file, I added Nagios server IP address and added a 1 for dont_blame_nrpe. When I log into Nagios server an...

I uninstalled Nagios using yum remove nagios. I then installed Nagios 4.4.3 from Source. I can log into Nagios web interface and view localhost and see services are being monitored. when I try to monitor a Windows machine the host does not appear in Nagios web interface. I followed Nagios core web d...

Hi there @scottwilkerson, I ran yum --enablerepo=epel update nagios , then a systemctl status nagios.service and Nagios failed load. Nagios is down again. When I run nagios -v /etc/nagios/nagios.cfg it tells me config file 'etc/nagios/server/windows.cfg' has an issue on line number. When I go and co...

Hello @scottwilkerson, That's correct my CGI location is different and I verified that by going to vi /etc/nagios/cgi.cfg and noticed Nagios version is 4.3.2 . But when I go to /usr/local/nagios/etc/nagios and I vi cgi.cfg I see Nagios version 4.4.3 . Also when I access Nagios web interface by enter...
