ConfigSource for Alert Rules Configuration
There is no way to backup Alert Rules configuration in LogicMonitor so I came up with this ConfigSource for LMConfig to keep track of configuration changes to Alert Rules.
Groovy Script

·9 years ago@Mosh thx for the submission.
Instead of posting the entire source code, so that others need to copy/paste it all, submit it to the LM Exchange and post the locator ID here.
Makes it way easier to share.
