You can uncheck the "[field]owner = [value]db" property in the alert when that group is doing work on their servers.However, as you mentioned, you'd still have the problem managing alerts when one group is used in multiple alerts.
any info on the best way to organize alerts?
I would like to supress a alert after acknowledged so that the alert does not keep firing off while bringing the link up and down for maint or testing. In detail, there are several nodes that are listed and I need to supress the alert for the individual node that is in maint or testing.
