In windows, is there a way to setup dynamic dates on logs filenames monitoring using check_mk_agent’s [logfiles] section?? In linux I know we can use $(date +%Y%m%d), but don’t know if it works on windows.

WATO is especially useful for administrating all of our static Windows and Linux based servers through a GUI once the check_mk agent is installed manually. I wanted to ask what … Read more

And here’s the question: Check_mk supports showing hosts/services based on contact group membership. But I can’t use the Nagios contact groups in check_mk.
