Collecting Data

HP Integrity Essentials Capacity Advisor works best with a lot of data to generate reports and create scenarios. It is best to collect data on a regular schedule; you can also trigger an up-to-date data collection for reports and profile generation. Collected data is kept on a managed system for 30 days and on the CMS for two years.




	IMPORTANT: The data collection process is purposely designed to consume little resource on the systems from which data is being collected. This means you can feel free to collect data whenever you want. However, the data collection process can take a relatively long time to run to completion when collecting data from a large number of systems.




	NOTE: You can import OVPA data into the historical database; see “Importing OVPA Data” in HP Integrity Essentials Capacity Advisor User's Guide (Part Number T2784-90005) and the capovpaextract(1m) manpage for additional information.Some of the menu items described below are repeated on other menus. Where an item is repeated on multiple menus, any of the duplicate menu items can be used to accomplish the result.

Once you have gathered data using the process described below, you may want to see reports or graphs based on the collected data (see Overview of Graphs and Reports) or build models based on the data to help plan future systems by creating scenarios (see Overview of Working with Scenarios).

First Data Collection

Prerequisites. To gather data for the first time:

You must be logged in to HP Systems Insight Manager (see Accessing Capacity Advisor).

Procedure 4-2 To Gather Data the First Time

Select OptimizeCapacity AdvisorCollect Capacity Advisor Data ALL... from the upper, HP SIM menu-bar.
This will start the wizard for collecting data from all systems licensed for Capacity Advisor.
Click the Schedule button.
The Schedule Task screen will be displayed.
Select Periodically from the list labeled When would you like this task to run?.
In the area labeled Refine Schedule: set the top line to 1 day(s) at 12:01 AM using the interval and time fields. (Use a different time if this is a busy time for your systems.)
Under the list labeled In addition: click the check box labeled Run now.
Click the Done button.
The Task Results screen will be displayed. Once the Status field shows Complete, the collection task is complete. An Exit code that is 0 means complete success; positive values indicates partial or complete failure. For a complete explanation of the error codes, see the capcollect(1m) manpage. The results of the task are presented in the Stdout and Stderr tabs. The messages on the Stdout tab include indications of any errors that occur (see “Error Notification on the Standard Out Tab”, below, for an explanation of the messages). Be sure to check both tabs for a complete understanding of what happened.




	IMPORTANT: If you do not get data on systems you expect to have data from, triggering the license scan can help. To trigger the license scan: Select ToolsVSE Management... from the upper menu bar. The VSE Managment screen will be displayed. Select ToolsVSEMgmt Licenses... from the lower menu bar. The VSE Management: Scan for Licenses screen will be displayed. Click the Scan Systems button.

Updating Collected Data

At times, such as when you are generating reports and developing or refining scenarios, it is desirable to trigger data collection so that your work is based on the most up-to-date data. Some possible cases are:

Bring the collected data on all available systems up to date ( see “Updating Collected Data on All Systems”).
Bring the collected data from some systems up to date (see “Updating Collected Data on Selected Systems”).
Bring the collected data presented in a Profile Viewer report up to date (see “Updating Data Displayed in a Profile Viewer”).
