AppDynamics-How I can alert for missing tiers after application patching

[173022]

Hi Experts,

I have a scenario in which there are 10 tiers associated with an application. After updates/patching, some tiers are missing in the APpDynamics console. So is there any way we can create an alert when this scenario happens?

Is a health rule with adding tiers manually will help to get an alert, as I don't have a real-time scenario to test.

Thanks.

Hi,

you could set up a health rule of type "Tier / Node Health - Hardware" for the respective tiers and test for metric "Agent|App|Availability".

You could either set it up on a node level and test for value != 1 to get alerts for every missing node or you could set it up on a tier level using "< Specific Value" for the expected amount of nodes in that tier. A "< baseline" condition might also work for this use case.

Under Conditions, you should also set Evaluation for "no data" scenarios to Critical or Warning to actually get alerts when no tier/node is reporting because it will not send 0 but instead there will not be any value at all.

Best,
Franz

The updates mentioned in the scenario are application updates/patching. Not related to appdynamics agent upgrades.
