Description:
Agent can reach database but it shows down in the dashboard. The database is up and running.

Two agents running on the server, each monitoring a single instance.

Appears as though there is no <server.reachable> data being sent.

How to repeat:
Not sure how agent got in this state. Appears to come and go after restarts, but not consistent.

Suggested fix:
Database is running, it should be shown as up.
