In that manual we will show you some options to monitor tcp/udp ports with Checkmk
We do provide some active checks to monitor the functionality of applications like DNS/HTML: https://docs.checkmk.com/latest/en/active_checks.html
Agent Plugin "Established TCP/UDP connections"
We do provide a netstat plugin collecting the network statistics. To configure the plugin, you have two ways:
copy the corresponding plugin to the monitored host like described here: https://docs.checkmk.com/latest/en/agent_linux.html#manualplugins
Setup → Agents → Windows, Linux, Solaris, AIX → Agent rules → Established TCP/UDP connections → New rule: Established TCP/UDP connections
- now you will need to configure the corresponding service rule. In that case, it's an enforced service
Setup → Services → Enforced services → Monitor specific TCP/UDP connections and listeners → New rule: Monitor specific TCP/UDP connections and listeners
