An application server monitors the activity of threads on which system alarms execute. When a system alarm thread has been active longer than the time defined by the alarm thread monitor threshold, the application server logs the following warning in the system log. This message indicates the name of the thread that is not responding, the length of time that the thread has already been active, and the exception stack of the thread, which identifies the system component.
When you do capacity planning, you need to look at the costs that are involved in running requests and how many requests you process over a set period of time. You can use the SMF Subtype 9 record to monitor which requests are associated with which applications, how many requests you get, and how much resource each request uses. You can also use this record to identify the application involved, and the CPU time that the request consumes. Because a new record is created for each request, you can determine the number of requests that you get over a specific length of time.
