I'm building dashboards for LAN/WAN/Router/Switch groups, and I've added Alarms as part of the dashboard. we get an error:
"An unexpected error has occurred. Please check the logs for any error messages."
Release : 3.7
Component : IM Reporting / Admin / Configuration
To fix this now, update Performance Management to r3.7.11 or newer. Starting with the r3.7.11 release the timeout being reached in Performance Management has been both raised by default from 100 to 120 seconds, and also is now configurable. If we still see the issue at 120 seconds it can be raised to avoid failure.
This is the entry from the Fixed Issues list that details the change:
Or change the following parameter in http://PC:8181/pc/center/admin/debug/attrs
AlarmView_WebService_Timeout from 120 to 200
SpectrumStatus_WebService_Timeout from 120 to 200
Additionally with the Spectrum r10.4.2 comes a change to the REST calls available for Performance Management to utilize. They resolve the issue with query performance improvements that avoid the timeouts. A future yet to be determined release of Performance Management will then take advantage of the new Spectrum REST calls to utilize them and further avoid the timeout failures.
