Configuring Percentile Values for Custom Capacity Planning Report

The eG Reporter module offers a wide variety of reports using which one can cross-correlate and time-correlate across thousands of metrics collected from across the environment. Reports generated using trend data particularly can accurately reveal the past load and performance trends, using which future trends in load and usage can be determined. The Avg, Sum, Max, and Min values computed by the eG Enterprise on an hourly basis as part of its trend computations, help a great deal in determining potential sizing inadequacies and planning the future capacity of the environment. However, from a strict capacity planning perspective, Percentile values are deemed as more effective pointers to capacity inadequacies than the avg, sum, max, and min values.

To enable users to effectively plan the capacity of their environment, eG Enterprise allows administrators to configure the trend manager to compute percentile values, and then generate detailed Custom Capacity Planning reports using the computed percentiles.

To configure the minimum and maximum percentile values that the eG trend manager should compute for a measure, do the following:

1. Login to the eG administrative interface as admin.

2. To access this page, click on the icon available in the Admin tab. Then, select the Capacity Planning Report option from the Reporter sub-menu in the Settings tile.

Note:

By default, the Capacity Planning Reports option will not be available in the Reports sub-menu - i.e., users are not allowed to configure/generate capacity planning reports by default. To enable the generation of capacity planning reports, do the following:

• Edit the eg_services.ini file in the \manager\config directory.
• In the [MISC_ARGS] section of the file, you will find a CapacityReportEnabled flag, which is set to false by default. Change this flag to true.
• Save the file.

3. By default, the Configure Percentile Policy tab page will open. If percentile definitions pre-exist, then the list of existing definitions will then appear. By default, a definition named Default will pre-exist, which will be set to a maximum percentile value of 95 and a minimum value of
4. To add a new policy, pick the Add Percentile Policy option from the Percentile Policies list. This will invoke a page that allows the user to configure Percentile Policies. Here, provide a name for the percentile definition in the Percentile policy text box. Specify minimum and maximum percentile values in the Minimum value and Maximum value text boxes. Finally, click the Add button.
5. To view the associate details, click on the Show Associates icon.

To modify a percentile definition, do the following:

1. Click on the Modify icon.
2. The Minimum and Maximum values configured for the chosen percentile policy will then appear.
3. Change the required values and click the Update button to save the changes.

To delete a percentile definition, do the following:

1. Click on the Delete icon.

Note that eG Enterprise will allow the deletion of only those definitions that have not been assigned to any measure yet.

2. A dialogue box appears with the delete confirmation message. Click the Yes button to delete the percentile definition.
