Heh, I never claimed my script was perfect. :) The script works for what we need currently and evolves as we have issues with it. I know the ps isn't sufficent, but as of yet it hasn't been an issue. Once it becomes and issue we'll change it. All the script does is check if the applications are there, not if they're responding properly. We have some other scripts on other boxes that do that, but these applications haven't had those problems yet (knock on wood). Plus the users are quite well educated about what they ought to see, and on the rare occasion that something is really wrong they call my cell. This has happened about 5 times in the last year or two. Of those times, 3 were their proxy server choking, 1 was a real tomcat problem and the other was the raid array getting unpluged.
