Monitoring IMS

You can monitor IMS by using various IMS commands, utilities, tools, and user exits.

Monitoring the system
In order to gather problem determination and performance information, you need to monitor the status of the system on a regular schedule. For example, to determine if you should start an extra message region, you might monitor the status of the queues during peak load.
Candidate subsystem messages for monitoring
Certain messages that are issued by IMS and its component subsystems can be critical to detecting problems early and identifying their root cause.
Monitoring IMS Connect connections
IMS manages TCP/IP connections through IMS Connect, which serves as the TCP/IP gateway to IMS. The IMS Connect function can also be viewed as a TCP/IP socket server.
IMS system log utilities
The system log data sets are a basic source for statistics about the processing performed by the online system. Individual log record types contain data that can be analyzed in many ways. For example, you can select and format all activity pertaining to a specified user ID, or about IMS pools.
Gathering performance-related data
IMS provides the DB Monitor and the IMS Monitor that gather and format IMS performance-related data and record this data on a statistics log.
