> #### Changing WebSpeed Broker controls

> This section describes how to change WebSpeed broker controls.

> To start or stop the WebSpeed broker and to change its property settings:

> 1. Display the WebSpeed main page for the broker you want to start. See the "Accessing OpenEdge resource information" section for the detailed steps.
> 2. Click Broker Control in the Command and control section to display the Broker Control page as shown:

> This table highlights the controls that you can change:

> To... | Then...
> --- | ---
> Change the current setting of the Enabled property. Note: A checkmark displays to indicate that the Enabled property is set. To clear this option, click the checkmark in the box associated in the option; the checkmark is deleted to indicate that the option is no longer set. | Click Edit. Then select or deselect the Enabled property to add or remove the checkmark. You must also restart the WebSpeed broker so that the property change is recognized.
> Change the current setting of the Broker statistics available property displayed in the Broker Summary section of the Broker Control page. | See the "Data collection details" section.
> Toggle between stopping and starting the WebSpeed broker, depending on the current value displayed in the Status field. For example, if the broker status currently displays ACTIVE, the button label will read Stop WebSpeed. You can click this button to stop the WebSpeed broker; Fathom stops this broker and updates the value in the Status field to display Not Running. | Click Stop WebSpeed or Start WebSpeed.
> Exit this page without changing any values and redisplay the WebSpeed main page. | Click Cancel.

> ##### Data collection details

> Data collection ensures that broker-related performance statistics can be trended to the FathomTrendDatabase. Options and conditions available on the Broker Control page and the WebSpeed broker resource monitoring plan must be fulfilled to successfully implement data collection.

> On the Broker Control page, these conditions include:

> - Selecting the Collect Statistics check box to enter a check mark.
> - Starting, or stopping and restarting the WebSpeed broker; you must explicitly perform this step on the Broker Control page to effect this change.
> - The value TRUE displayed in the Broker statistics available field. (Fathom automatically updates this field when it detects that the Collect Statistics option is enabled after you have started, or stopped and re-started, the WebSpeed broker.)

> On the WebSpeed broker resource monitoring plan, you must also check the Trend Performance Data option.

> Note: You are not required to use trending with the data collection activity. However, without the Trend Performance Data option selected, you cannot trend data. Data trended to the FathomTrendDatabase is required for WebSpeed-related rule evaluation, graphical displays, and report generation.

> For information about the Trend Performance Data option and monitoring plans for WebSpeed broker resources, see Chapter 6, "Monitoring Plans and Rules for OpenEdge Server Resources."

> Note: Using data collection might cause the Web Speed broker to exhibit some level of performance degradation, memory degradation, or both.

> To set the options to perform data collection in a WebSpeed broker:

> 1. Check the current setting of the Collect Statistics field in the Properties section of the Broker Control page; it must be checked to indicate that this property is set.
> If the Collect Statistics field is not checked, then click Edit. In the Collect Statistics field, click in the check box to type a check mark. Click Save.

> 2. Stop and restart the WebSpeed broker you want to update.
> Caution: You cannot interactively change a running process. Therefore, you must restart the WebSpeed broker after you change the setting of the Collect Statistics field.

> The Broker statistics available field in the Broker summary section will display TRUE if the broker re-started successfully. The TRUE value indicates that you have successfully set data collection and that broker statistical data is now available to be stored in the FathomTrendDatabase.

> 3. Check the current setting of the Trend field in the Properties section of the Broker Control page; it must be checked to indicate that this property is set. See the "Default polling and trend values" section and the "Default monitoring plan details" section for details about this field.
