I have a version of the "Oracle_DB_BlockedSessions" datasource template deployed and set an alert threshold on a complex datapoint that accounts for WAIT_TIME and SECONDS_IN_WAIT. Here is the complex datapoint expression for those curious--- if( eq(if(un(WAIT_TIME),0,WAIT_TIME), 0), if(un(SECONDS_IN_WAIT_RAW),0,SECONDS_IN_WAIT_RAW), 0) If the complex datapoint has a value over 300 seconds, an alert triggers with all the enriched instance-level autoProps from the Active Discovery script. All other aspects of this template mirror the gold-standard version--including enabling the "Automatically Delete Instance" option. Enter Client X, and they are comfortable with a threshold of 900 seconds. How can I set this custom threshold at a resource group for Client X when they don't currently have any blocking sessions? If I do manage to catch and set this Alert Tuning customization when Client X has a blocking session, will this alert tuning get wiped out when the DSIs are removed automatically? I suppose the Active Discovery script could be modified to always output a dummy instance... but that leaves an unpleasant taste in my mouth. Aside from cloning the datasource just for Client X, are there any other alternatives? And no, I do not want to alert off of the "Oracle_DB_BlockedSessionOverview" template because a it doesn't do a good job of discerning between one really long blocking session versus sequential and short-lived sessions that happen to exist at the time of the poll.
