Has anyone done monitoring on Red Hat clusters on versions older than rhel 5? I'm currently having some rhel 4 (and 3 if I remember correctly) clusters and the cluster probe won't work on so old platforms. Neither is it supported.
I'm implementing my own solution, which does have room to improve (and of course, not much time to do so). I would be intrested in hearing what solutions others have found, or if you've somehow managed to get the cluster probe running.
