This poller will tell you the config sync status of an F5 (high availability pair). I used this in conjunction with NCM to detect and alert on config changes.
1. Its good visibility on config sync status.
2. For us, once Orion detects that the configs are out of sync on the primary node, we get an email, an alert in Orion, and it fires off the real-time config change detection feature of NCM
3. If you know SQL, you can write a SQL query to just email you the status when it changes.
