Configure an SNMP trap server to collect information on the average latency between the Primary and Standby server.
When Address Manager database replication is configured, the database of the Primary server is replicated to the Standby server. Monitoring the database latency between the Primary and Standby servers provides insight as to how far behind the Standby server is compared to the Primary server.
- Load on the Primary server
- Load on the Secondary server
- Network capacity and utilization between the Primary and Standby server
When configuring SNMP polling for the database replication latency value, BlueCat recommends capturing values over an interval to establish a baseline for normal replication latency in your environment.
To monitor the database replication latency, you must first configure the SNMP service on Address Manager from the BlueCat Address Manager System page of the Address Manager user interface by navigating to . Once you have configured the SNMP service on Address Manager, you must configure the SNMP monitor or trap to poll for the .replicationAverageLatency MIB.
For more information on configuring the SNMP service on Address Manager, refer to Configuring SNMP on Address Manager. For more information on the MIB definitions, refer to SNMP Manager setup and BlueCat MIB files.
