Please follow the below step: -

1. Increase the heartbeat interval from 10 to 30 seconds. In order to do so please open the spectrumgtw.cfg file and change the the key 'heartbeat_interval = 10000' to 30000.

2. Restart the Spectrumgtw probe

Additional Information

The alarm count increase that you see in USM is not updating in Spectrum. If you need to have an accurate picture you should look at the Time Origin in the alarm subconcole of the UIM Infrastructure Management. The Time Origin should be the same you see in Spectrum.
