Response Time Analyzer (RTA) analyzes the response time of IMS transactions and breaks down the response time into the following components:
With ETE the following response times are displayed:
Response time groups can consist of:
Response time is displayed in several ways:
RTA Interval workspaces provide information on three user-defined intervals. The second interval must be a multiple of the first. The third interval must be a multiple of the second. For example, you can define intervals of 10 minutes, 30 minutes, and 60 minutes. When an interval expires, the contents are rolled (added) to the next interval and then cleared. Collection continues with empty buckets. In the previous example, the first set of buckets are cleared every 10 minutes, the second set up buckets cleared every 30 minutes and the third set of buckets cleared every 60 minutes.
Slots represent user-defined intervals (up to 48). The 24 hours that comprise a day are divided into slots; slots may not overlap, but can have gaps. RTA collects response time information into the current slot. Before switching to a new slot, the system clears the new slot. Thus, response time information is collected for almost all of the prior 24 hours.
The IMS RTA Interval Summary and IMS All RTA Interval Summary (for all managed systems that are currently collecting RTA data) workspaces, based on the IMS RTA Interval Summary and IMS RTA All RTA Interval Summary attribute groups, are comprised of a table view and four bar charts (one for each of three intervals and one for elapsed time). The table view contains one row per interval per IMS (three intervals total). Each row contains interval size, interval elapsed time, R0 transaction count, average R0 response time, worst R0 response time, and the input IMS ID. Each interval bar chart displays average R0 response time and worst R0 response time for each IMS. The elapsed time bar chart displays the length of each interval and the elapsed time.
