We would like to set the node red when one specific application monitor is red. Right now, when the application monitor is red, the node is yellow. I do not want to set a group red just a single node.
The logic is: You need to alert on a Node, so you can set a custom status.
Because of that you'll need to use a Custom SWQL Alert (Advanced) based around the "Node"
Since the alert is "based" around a node, you can tweak the node's custom status as an alert action.
This should work as written, but I don't have anything handy in my lab on which to test, so test it yourself and tweak the requirements as needed.
Calculate node status in the SolarWinds Platform
The documentation does not appear to describe how to make a single, specific application monitor "down" set the node to red/critical. Using the information in the documentation, I can cause the node to go red for ANY application down status using the "Worst" rollup mode but it does not allow me to choose one specific application monitor. For example, say I have 3 assigned application monitors: A, B, and C. I only want the node to be red when monitor B is down but not A or C. When A or C is down the node should be yellow.
You could manually set the node status based on the component status. It's explained in Manually set a custom status in the SolarWinds Platform.
I appreciate the suggestion. I investigated this approach but receive this error: "action has failed Execution of CustomStatus action with Entity type - Orion.APM.Component failed. CustomStatus alerting action works only with Orion.Nodes."It appears I cannot "alert on" Component, I have to use Node, but then I cannot use a component trigger condition.
