I really like Dell's OMSA utility for remotely checking the health of my servers. My only complaint is that they don't make it easy to configure pro-active email alerts. On a Linux system this should be trivial, and yet the designers of OMSA didn't add a global notification setting so you have to edit every possible notification separately. On top of that, the suggested command line in the help system sends a very generic message.
So, I wrote a OMSA log parser that can send a specified email address the last X entries in the log when OMSA detects an event.
