Tivoli Performance Viewer functionality

Depending on which aspects of performance are being measured, you can use the Tivoli Performance Viewer to accomplish the following tasks: View data in real time or view historical data from log files. View data in chart form, allowing comparisons of one or more statistical values for a given resource on the same chart. In addition, different units of measurement can be scaled to enable meaningful graphic displays. Record current performance data in a log and replay performance data from previous sessions. Compare data for a single resource to an aggregate (group) of resources on a single node.

Given all this data, the Tivoli Performance Viewer can be used to do the following types of analysis: Monitor real-time performance, such as response times for servlet requests or enterprise bean methods. Detect trends by analyzing logs of data over short periods of time. Determine the efficiency of a configuration of resources (such as the amount of allocated memory, the size of database connection pools, and the size of a cache for enterprise bean objects). Gauge the load on appservers and the average response time for clients.
