Modifying the Test Configuration

Once the code snippet is inserted into a web page, every time a user loads that page onto his/her browser – i.e., accesses that page via a browser – the browser will run the code snippet, which in turn will download and execute the egrum.js Java script. The script will capture the load time of the page and Java script errors that the page encounters. The browser will then send these user experience metrics to the RUM collector.

To gather the metrics reported to the RUM collector, the eG agent periodically runs tests on the data collector. By default, these tests are pre-configured with the following:

• Test frequency;
• Proxy server details
• How many page views are to be tracked?
• URL and Javascript error patterns that are to be excluded from monitoring;
• Slow transaction cut off
• The depth of metrics to be collected as part of detailed diagnosis

If required, you can fine-tune the test configuration to suit your needs. For instance, you can change the test frequency, increase the number of page views you want tracked, exclude more URLs from monitoring, etc. For this purpose, you will have to reconfigure the tests.

To reconfigure a test, follow the steps below:

1. Select the Specific Configuration option from the Tests menu in the Agents tile.

2. Select Real User Monitor as the Component type and pick the RUM component being managed from the Component name drop-down.

3. Then, from the CONFIGURED TESTS list, select the test to be modified and click the Reconfigure button.

4. The parameters of the chosen test will then appear. You can make the changes you require, and click the Update button to save the changes. Detailed explanation for each of the parameters and how to modify them is available in Monitoring using the eG Real User Monitor.
