Hi @alexis and welcome back to the community!
Well the symlinking will not help you if you need the check on a different host.
How you go about MKP in general is this:
- Install the MKP
- Activate Changes
- If an agent plugin is necessary make sure it is on the monitored host
- Discover services
The way how the plugin files come to the monitored system depend on your environment. If you have the CEE or CME you can distribute the plugin facilitating the agent bakery. Here it depends on the MKP if you get a nice rule for that plugin in the UI or if you need to deploy the file using the Deploy custom files with agent rule.
If you are running CRE you generally need to distribute the plugin files yourself. Either by copying them manually to the necessary host or by using some kind of automation like Ansible.
