We have encountered a strange problem; I have recently installed a Nagios XI trail version as we are evaluating monitoring solution for our AWS Cloud.
I was able to successfully add hosts to Nagios Nagios XI using Configure -> Monitoring Wizard. After adding the hosts I see that all the host status is down. However when I see the Services Status everything looks perfect and has OK status.
There is warning message: This plugin must be either run as root or setuid root. But I have confirmed this that all the plugins under /usr/local/nagios/libexec all have their user set as ‘root’.
Can you please let me know what could be the possible causes and resolution for the same?
Service Status Details For All Hosts = OK
Host Status Details For All Host Groups = DOWN
Status Information: Warning: This plugin must be either run as root or setuid root.
Note: I have attached screen shots for your reference

Nagios XI: Host Status DOWN

Re: Nagios XI: Host Status DOWN
Could you go to Configure > Core Config Manager > Monitoring > Hosts
Click on the floppy icon on one of the hosts that is failing and post back the settings.
Also, can you run this command in the server and post it back. You need to capture it to a file and attach it to this post. The screen capture didn't show the full output.

Re: Nagios XI: Host Status DOWN
The "check-host-alive" command runs the "check_icmp" plugin. This plugin requires suid permissions. You screenshot does not show this plugin, so can you check the permissions on it?
Code: Select all
ls -la /usr/local/nagios/libexec/check_icmpFormer Nagios employee
"It is turtles. All. The. Way. Down. . . .and maybe an elephant or two."
