Monitor Key System Resources

Establish regular monitoring of key system resources, such as space, CPU, I/O, response time, and so on.

Business Value:

By monitoring critical resources, you can anticipate increased demands and avoid unanticipated interruptions in service by preemptively taking corrective action.

Additional Considerations:

You should monitor resources such as database space, index efficiency, response times, CPU, I/O, and buffer utilization. To monitor these resources, periodically capture relevant statistics and review them looking for trends and sudden changes.

CA IDMS provides several monitoring facilities. The following table identifies facilities that can be used to monitor critical resources.
