Monitoring activities of Db2 Connect gateways and connections of DCS applications

You can monitor the activities of DB2 Connect servers (DB2® subsystem) that serve as Db2 Connect gateways. You can also monitor the connections of Database Connection Services (DCS) applications within the Distributed Relational Database Architecture™ (DRDA) of DB2. You can use the information that you obtain through these monitoring activities to evaluate the health of a Db2 Connect gateway and to make changes necessary to tune the system.

To monitor the activities of a Db2 Connect gateway and the connections of DCS applications, your system must meet the following criteria:
  • Performance Expert Agent for DB2 Connect Monitoring is installed on the system, on which the Db2 Connect gateway runs, and is configured.
  • At least one OMEGAMON® Collector is registered for a Performance Expert Agent for DB2 Connect Monitoring.
  • Performance Expert Agent for DB2 Connect Monitoring and the OMEGAMON Collector are started.

Refer to Configuration and Customization for information about how to install, configure, and start Performance Expert Agent for DB2 Connect Monitoring and to register the OMEGAMON Collector.

Performance Expert Agent for DB2 Connect Monitoring periodically collects snapshots of performance-related information about the Db2 Connect gateway and the connections of DCS applications and sends them to the OMEGAMON Collector. One Performance Expert Agent for DB2 Connect Monitoring can send data to one or more OMEGAMON Collectors, and one OMEGAMON Collector can receive data from one or more Performance Expert Agents for DB2 Connect Monitoring. The collected data is stored in the DB2PM database of the OMEGAMON Collector.

Figure 1 provides an overview of how the activities of Db2 Connect gateways and the DCS connections are monitored.

Performance Expert Client enables you to view the collected data from various perspectives. You can view:
  • A list of all Db2 Connect gateways that are connected to a specific DB2 subsystem. You can also view Statistics details on them.
  • Statistics details on a specific Db2 Connect gateway, independent of any DB2 subsystem
  • A list of all DCS applications that are connected to any DB2 subsystem and view details on them
  • Information about the DCS application that is related to a specific thread
