[lvs-users] ldirectord email features

I'm a fan of ldirectord so I am proposing a possible feature. ldirectord
sends me an email alert when services go down, which sometimes works too
well. A few months ago I was replacing some switches and make a spanning
tree mistake which caused ldirectord to be unable to reach any of my
realservers. It took me a while to find the problem, during which I made
several changes to the network infrastructure. As a result, I got about
2500 text messages on my cell phone from ldirectord. More recently, I
enabled a script that restarts certain services every night, so now I
get 250 text messages on my cell every night!
I wish there was a way to tell ldirectord stuff like this:
1. Don't send alerts during certain time windows
2. Except always send alerts for certain services or hosts, even during
excluded time windows
3. If you find that you are sending a lot of alerts in a short time
frame (say, more than X per second), wait Y seconds and send an email
digest, not separate emails for each alert
That's my Christmas wish list!
