Defining custom error-detection rules and notifications on the Analyzer
A web application can encounter a variety of problems. Most of them are handled by the default system error-detection rules in BMC Real End User Experience Monitoring Software Edition. However, you can extend this capability with up to 100 custom error-detection rules that reflect specific needs of your web application.
Typical use case
Many application environments have their own error pages that handle problems gracefully.
There is two ways to detect this error:
You might only care about a 404 Page Not Found error only if it affects a container or a document but not a component of a page.
Turn off the system default "not found" error-detection rule and replace it with a more detailed one that looks for "not found" errors on certain types of objects.
Subjective or performance errors
If a PDF file takes more than 2 minutes to download, you might consider this a problem.
Create a custom rule that is triggered when objects ending with .pdf have an end-to-end time longer than 2 minutes.
Interesting events in your web traffic
You might consider a particular user's logging on to be important.
Define an error-detection rule that contains an informational condition to watch for this.
In the Administration > Thresholds and problem detection > Error detection rules page of a Real User Analyzer, you can perform the following operations:
- Edit email alert settings for all the rules
- Edit rules
- Copy rules (to create a rule with similar settings to another rule)
- Delete rules
- Change severity for the rules (Error or Informational condition)
- Change categories for the rules:
- Network error
- Client error
- Server error
- Application error
- Content error
- Custom error
- Change priorities for the rules (the order of rules firing)
- Performing bulk operations to the selected rules (turn on of off, enable or disable alerting for a rule, etc.)
