As we make the rounds and our clients see the benefits of Watchman, we will then usually push it out with ARD to all of the machines on their network.
I just did this a few minutes ago for a client who runs their business on a Mac mini Server using FileMaker Server, and Watchman emailed me almost instantaneously about a degraded RAID on the mini.
Upon further investigation, I discovered that one drive is down completely. I'm sure we would have found this problem "eventually", but with so much else going on it's hard to be proactive sometimes and actually take the time to check the status of so many machines.
Watchman makes it painless. Thanks Allen, thanks Watchman!
