Chapter 3 Working with Dynamo Web Sites

Using the Performance Monitor

The Performance Monitor is a Windows NT tool that provides feedback on the performance of the following Dynamo-related items:

Cache Hit Ratio Number of times a document is found in the cache versus the number of times the cache is searched.
Cache Used Percentage of the document cache in use.
Database Queries/Sec Number of queries per second being performed on the database.
Documents in Cache Number of documents currently stored in the cache.
Dynamo Connections Current number of Dynamo connections.
Scripts Run Total number of scripts that have been run.
Scripts/sec Number of scripts being run per second.
Total Database Queries Total number of database queries performed.
Total URL Requests Total number of URL requests processed by Dynamo.
URL Requests/Sec Number of URL requests being processed per second.
User Connections Current number of user connections.

To run the Performance Monitor:

Connect to the Web site you want to monitor. You can monitor multiple Web sites at the same time if they are each connected.
From the NT Desktop, Select Start | Programs | Administrative Tools | Performance Monitor.
From the Performance Monitor select Edit | Add to Chart.
From the Add to Chart dialog window, select PowerDynamo as the Object. The Instance field displays the Web sites to which you are connected. You can display information in the instance field for a maximum of ten connected Web sites.
Select the first counter you want to monitor, and the appropriate Web site from the Instance field. Click Add.

Repeat this step for each counter you wish to display.
