Snmpcollector stops collecting data for devices that are temporarily unreachable if the snmpcollector profile is rediscovered via the "Force Component Rediscovery" or "Hours between rediscovery" when the device is not reachable. All subsequent rediscoveries after the device is online are successful but metrics are not collected
NOTES:
**The snmpcollector profile is displayed in good standing after the "Force Component Rediscovery" or "Hours between rediscovery" task.
**If the "Reachability" QOS and Alarm are enabled, the snmpcollector stops collecting "Reachability" metrics and alarms are not generated.
**Deactivating/Activating the snmpcollector resolves the issue
