Hi ,
I’m trying to add a few windows hosts for monitoring but check mk was not able to detect any services when I do a service discovery . I’m using a custom port for connectivity . Tried checking telnet to the to be monitored host on the port which shows its connected but I dont get a services output which I get when I do a telnet to another hosts which is working fine . Any help will be much appreciated! Thanks !
Check MK version : Enterprise 1.6.0p20
Windows Host server 2008 R2
Agent Output for the one where it works
Trying xx.xx.xx.xxx
Connected to xx.xx.xx.xxx
Escape character is '^]'.

Have a look if you can locally to the custom port. If this differs from remote connection, then it is a firewall topic, either the local firewall or a central one.
If it does not differ, try running the agent manually with the parameter “test”.
Hi Dennis,
Tried running the agent manually with “test” parameter on the windows host and we did get the agent output there . However we are unable to get these services on the check mk console .
Also tried doing a telnet from the command line and got output in both the cases locally and from the check mk host remotely
The problem is obviously the rule ‘Individual program call instead of agent access’. Deactivate it, and try the ruleset ‘TCP port for connection to Checkmk agent’ for configuring the right port.
