SDT for Services and Devices
I have multiple sites running our system. I have a device group for each site consisting of all devices (db, web etc) and a corresponding Services group (same name) for monitoring the web site.
If I need to take down the site for maintenance, I need to update both the devices and services with the downtime.
My suggestion: Add rules on a device level of which services to take down when the device goes to SDT.
Examples:
1. if I have a test machine (single machine running test.domain.com), I can tell the rules that when the machine goes to SDT put down the service monitoring of test.domain.com
2. I have 3 machines running a load balanced site (site.domain.com), I can tell the rules that if all machines running this site are going to SDT put the service to SDT
3. I have an external site (external.domain.com) which is hosted elsewhere, because of that it will not be put down when any of the devices go into SDT
