FYI, Red Hat has made the announcement that CentOS 7 will reach end of life (EOL) on June 30, 2024. Once it's EOL, you will no longer be able to install or upgrade new software versions. Plus, if you want to perform a migration to a newer OS, you won't be able to install CentOS 7 on a test server for proper migration testing. You may want to take this time to upgrade to CentOS Stream/RHEL 8/9 or a newer, supported version of Ubuntu and Debian if you can. (Side note: we'd be happy to help you if you need it).

Hi @makwanapratikp - I'm guessing there's an error in your configuration, but the service output is missing most of the important details. Can you show us the output of the following command?

tail -50 /usr/local/nagios/var/nagios.log
