AES Node Unavailable Health Alert
When AES is monitoring a node that goes down, it triggers a "node unavailable" alert email. I'm trying to find out the following.
- What is AES using to determine that the node is unavailable? If the server crashes, I'm guessing it won't be guaranteed to be able to send a message to AES via SOAP to tell it it's going down.
- Does AES store the "node unavailable" message in AES pega logs or is it just stored in pega DB tables or is it a runtime decision based on the connection to the node being monitored.

Monitored nodes send AES a health status message (HLTH0001) every two minutes. There is an agent that runs in AES that checks if health status message has been received. The server does not tell AES that it is going down when it is crashing - AES does not receive health status message and assumes the server has gone down.
Health status messages are persisted to class PegaAES-Data-NodeStats. Agent maintains the most recent node health state in class PegaAES-Data-NodeHealth. The AES dashboard data is in class PegaAES-Data-Indicator.
