Regular expressions in user_alert.conf

I was wondering how fancy I can get with regex in the user_alert.conf file for alerting?


I had this configuration:

alert vip_down "Virtual (.*) has become unavailable" {

email toaddress=""


body="BIGIP: VIP Down"



But I want to ignore a single VIP that has some troublesome nodes. To that end, I changed the match string to this:

"Virtual ((?!\/Common\/VIPNAME).)+ has become unavailable"


I'm by no means a regex wizard but that seems to work based on my testing. However, if I configure that in the user_alert.conf file the alertd service constantly restarts, complaining about this line.
