Note : This scenario was tested on ITM 6.2.3 FP1 and also an example is for "CPU Utilization"
One may use similar configuration for other domains like ITCAM and others that ITPA supports.
If this message appears on the TEPS GUI for a certain task - it means that a) either the Historical Collections was not configured or b ) there was insufficient Historical data to do its' computations.
E.g:
This means that the CPU Utilization for the OS agent was not configured. ( in this case I am testing it on a RHEL 5.8 - Linux )
The message can be either a "FAILED - Not Sufficient Data Points"
or "COMPUTED - Not Sufficient Data Points"
The "Failed" message (as seen above ) means that the historical configuration was not done.
The second error message you could see is "COMPUTED" however,it will show Not Sufficient data -points as seen below. This means that there are not sufficient collections for the Performance Analyzer to do computations on.
To fix this:
Click on the History Collection button :
Go to Linux : and create a new collection for Linux CPU (Superseded.)
Right click on "Linux" and Create a new Collection. ( if not done already )
Basic Tab:
Collection configuration:
Distribution tab: Move your server or the group under "Start Collection on"
Set up the configuration for Warehouse and the Summarization Agent.
Enable the Daily, Weekly, Hourly and also Detailed data on Summarization and Pruning Agent.
Now, setup similarly the History collection on ITPA Domain ( in this case the OS Agent):
Click on the Tivoli Performance Analyzer Domain for OS Agent.
Check that the managed server/Group is configured for collection, under the distribution tab.
Set up History collection settings.
Now, let the analytical task for this agent run,
After the task is run, the TEPS GUI ->Performance Analyzer -> OS - will show a different message.
It did compute - however
Yet, the "Not sufficient Data points" is still showing- because ITPA needs a certain amount of data before it can analyze and predict the trend for this instrument.
Once the data is there - this message should go away.
