If the performance metrics indicate a performance degradation in Escalation, add worker threads to improve performance. Increasing threads to 10 worker threads is acceptable, but keep in mind that more threads may require additional or more capable CPUs. Be conservative when increasing threads, since this action may reduce the overall resources that are available and affect performance. Increase the value in the ics-default.xml file. The VMware Smart Assurance Service Assurance Manager Configuration Guide provides information on reconfiguring the Global Manager.
Once increased, the number of worker threads cannot be reduced unless the server is restarted.
