Issue:
No Events from CA Performance Manager (CAPM) are seen in CA Spectrum after integration was completed.

All other functions of the integration are working.

Threshold Events are raised in CAPM for items synced between the systems but the Events are never seen as Alarms in CA Spectrum.
Environment:
All supported CA Performance Management and Spectrum releases integrated together
Cause:
This error in the Spectrum Tomcat OneClick web server is clue to the cause for this problem.

The '...java:201' line is our key as it indicates Spectrum trying to convert the landscape.getNPCgroupID. The call getNPCgroupID is returning "". This means it doesn't have an ItemID for the Landscape Group. The ItemID of the Landscape Group is synchronized down to Spectrum from CAPM.

We can confirm presence of the landscape and it's ItemID in the MySql DB in CAPM named netqosportal. The following queries shows the values:

select * from t_group where ItemName like '%Spectrum Landscape%'\G;
select * from dst_group where ItemName like '%Spectrum Landscape%'\G;

If an ItemID is seen it shows the value is present in CAPM but missing from CA Spectrum.

When a Landscape moves to DOWN, Spectrum marks the landscape npcitemid to "". Also when a landscape is removed, CAPM will mark it's npcitemid to "". During PUSH in the synchronization cycles is the only time we'll set the npcitemid on the Landscape to a value other than null and "". 
Resolution:
Two options to resolve this:
A: Restart the Spectrum Tomcat OneClick web server services, or reboot the server.
B: Request a Full Synchronization of the CA Spectrum Data Source in CAPM via the Manage Data Sources page.
