Performance Collection Configuration

On this page, you specify the platforms you want to collect performance metrics from and the date and time at which you want the performance metric gathering to end. By default, the date is set to the current date and the end time to one hour ahead and “Windows-based machines” is selected.

The MAP Toolkit is capable of collecting performance information from both Windows-based and Linux-based machines in the same collection period.  Selecting “Windows-based machines” will enable collection of performance metrics from Windows machines using WMI credentials and selecting “Linux-based machines” will enable collection of performance metrics from Linux machines using SSH credentials. 

The minimum time required is 30 minutes of successful collection. If MAP fails to collect at least 30 minutes of performance data, you will not be able to run any of the wizards that require performance data. Be aware that time spent performing inventory data collection of machines may delay the start of performance data collection; it is therefore recommended that you perform an inventory of the target machines prior to running performance collection.

It is recommended that an initial 30 minute test run is conducted to ensure you are collecting data from the target machines.  Once you are satisfied that MAP is able to collect data from the target machines, a full run can be conducted. When deciding how long to run the performance data collection, we recommend you consider the following:

·         A minimum of 2 days’ worth of data is needed for the statistical calculations to start lining up with real world performance.

·         A run of 7 days or more is recommended in order to capture any variation in the utilization profiles of the targeted machines over the work week plus the weekend.

·         If there is reason to believe that the utilization profiles may vary for some other reason, such as end-of-month activities, then the performance collection should be run during that period of time as well.

·         Be aware that gaps of time between performance collection runs can affect the calculations used for aggregating performance data. It is therefore recommended that you not have long gaps of time, and that you collect from the same set of machines each time.

Performance counters are collected from each computer in five-minute intervals. The number of computers from which the MAP Toolkit can collect performance counter data successfully depends upon factors such as network latency and the responsiveness of servers.

Note: If you have previously gathered performance data, you will be prompted on subsequent performance counter gathering runs to either delete existing data or to append the newly gathered data to what was collected previously. If you split up your target computers to improve performance, select No in the Performance Data Exists dialog box.
