Administering an ISP Installation

Measuring Resource Consumption

To measure the amount of resources consumed by the sites in your installation, turn on process accounting. Once you know which site is using too many resources, you can decide whether to limit resources on that customer’s Web site (through process throttling) or whether you should take other actions.

To turn on process accounting

1. On the site’s property sheet, click the Home Directory tab.
2. Configure the Application Settings to High (Isolated).

   These first two steps make all applications on the site run out of process.

3. On the site’s property sheet, click the Web Site tab, and make sure Enable Logging is selected.
4. On the Web Site property sheet, click the logging Properties button, and select Process Accounting.

   The last two steps activate process accounting for that site.

With process accounting activated, you extend logging so that figures for the Job Object counters are recorded. With the information gathered from process accounting, you can then decide whether to upgrade the servers in your installation, to adjust the billing for this particular customer, or to limit the amount of resources the site can consume.

For more information about activating process accounting, see the “Tracking Processor Use” topic in the IIS 5.0 online product documentation.
