Spectrum data source sync is showing busy status, global sync not running.
This seems to go away after a while and then Spectrum syncs and the global sync runs.
Spectrum is doing backups around this time.
Performance Management
If any landscape in a Spectrum environment is offline or in a failed-over state, the Performance Management data source will not synch.
This is functioning as designed.
Spectrum will return a busy status when any landscape is offline or in a fail over state.
This is what will cause the Spectrum data source to show the "Busy" Status in the NetOps Portal UI.
Make sure that all landscapes are online and running on the primary SpectroServer.
