IBM Tivoli Performance Analyzer agent has the ability to analyze the historical data collected at the Tivoli Data Warehouse by several agents.
The ITPA currently can analyze historical data from six agents like OS, ITCAM, System P, Oracle, DB2, and VMware. ITPA when configured comes installed with different default tasks for each agent.
These tasks can be either modified or new tasks created making copies of the existing ones and changing the names plus other parameters, to suit the business needs. These tasks can be broadly classified as a) Analytical Linear Trend b) Non-Linear Analytical Trend c) and custom arithmetic tasks.
The Analytical LT( Linear Trend ) and the Arithmetic tasks are valid by default - however, the Non Linear Analytical tasks are only valid if the SPSS add-on component is installed.
Here is a snapshot of OS agent tasks that come installed by default. To view this at your end - you would click on the ITPA configuration button on the TEPS GUI.
A new window opens as shown below:
If you click on the OS Linux - the default tasks shows up as shown below. This lists all the analytical tasks including the a) Linear Trend b) Non-Linear Trend and c) Arithmetic tasks. One can click and modify the task run intervals, Change the trend interval, and look at the Status and Forecast parameters - which I will cover in another blog.
