CA APM Collectors starts to slow down after few hours.
IntroscopeEnterpriseManager Log contains many of the following informational messages:
[INFO] [PO:WatchedAgentPO Mailman ##] [Manager] TransactionTrace arrival buffer full, discarding trace(s)
CA APM Team Center uses Transaction trace data as the source for the Team Center Map by default. This causes the MOM to retrieve the Transaction Traces Data from Agents, occasionally which slows down the Collectors. However, the data source can be switched to use the Triage map data using the property in IntroscopeEnterpriseManager.properties:introscope.apm.appmap.legacy.data.source = When set to false (default), appmap data derived from transaction traces will be usedWhen set to true, legacy appmap data sent by the agents will be used
Set the below property to true on the MOM and Collectors IntroscopeEnterpriseManager.properties and restart the APM Cluster.
