Two things you need to know about Charles:
1. He is one of the best resources on Unix/Linux monitoring with SCOM outside of Kris Bash & and the PG.
2. He has an awesome new MP he just released that fixes the age old problem of Monitor based alerts being closed while the monitor is still unhealthy. I have seen customers solve this in the past with Green Machine, but the problem with Green Machine is unless it is applied carefully it becomes a state churn monster in your environment. Sky Blue has some slick PowerShell filtering logic to go only after those pesky monitors/alerts that need it while leaving the rest alone.
