Is there a way to enable the below entry in /usr/local/nagios/etc/nagios.cfg file. I did search using yum and dnf package manager on CentOS Stream release 8 but unable to locate livestatus.o addon or install it. broker_module=/opt/local/livestatus/livestatus.o /tmp/live.sock Any help will be highly appreciable. Please guide/suggest. Thanks in advance. Best Regards, Kaushal
