Nagios Support Forum

After observing the RHEL 10 nagios instance for some time, I see that there is a subtle error lurking. With selinux non-enforcing, everything works well. With selinux enforcing, a login test that I wrote, using expect, fails. Unfortunately, there is no selinux violation that can be remediated to fix...

I'm happy to report that as of today, my test nagios server on RHEL 10 is successfully running all tests (24 hosts, 133 checks) including the tests which were failing before. Updating the password on the mysql server fixed the mysql problem, and selinux exceptions apparently fixed the rest.

I recently decided to build a new Nagios server based on RHEL 10, and I discovered that epel had no nagios packages for RHEL 10. I built RPM packages from the Nagios 4.5.9 source and installed them. Nagios started up nicely, but then I noticed that 2 of my test indicated failures. The DHCP server te...

I'm trying to replace the nagios check_procs plugin with the native ncpa facility, but it seems to have some limitations. One of them is described thusly: I'm checking for a process called "Autosched.bora9.bsh" - $ ssh drslinap3d ps -ef|grep Autosched.bora9.bsh espbatch 9714 1 0 Apr08 ? 00...

Well, interesting - since you were seeing the snmp-mibs-downloader, I took a look at another 18.04 instance, and that package comes up there. The only difference I can see in the sources.list is that the box where it's working has "multiverse" appended to the first 3 lines. In like manner,...

I've been using nagios open source with great results, so naturally I was interested in taking nagios xi for a spin. I spun up a new ubuntu 18.04 LTS instance, and run a full update. I downloaded xi-5.6.7.tar.gz, untarred it, entered the nagios directory and typed "./fullinstall" Hard fail...

I'd been using nagios on centos 7 for a couple of years and everything worked as expected. Yesterday it updated from 4.3.4 to 4.4.3 and DNS checks all began failing. All of the monitored DNS servers are working fine, but nagios always returns an error of the form: DNS CRITICAL - query type of -query...
