Max Grouped URLs Per Measure Period
This parameter will appear only if the ADVANCED SETTINGS flag is set to ‘true’. This test groups URLs according to the MAX URL SEGMENTS specification. These grouped URLs will be the descriptors of the test. For each grouped URL, response time metrics will be aggregated across all transaction URLs in that group and reported.
When monitoring web sites/web applications to which the transaction volume is normally high, this test may report metrics for hundreds of descriptors. If all these descriptors are listed in the Layers tab page of the eG monitoring console, it will certainly clutter the display. To avoid this, by default, the test displays metrics for a maximum of 50 descriptors – i.e., 50 grouped URLs alone – in the eG monitoring console, during every measure period. This is why, the MAX GROUPED URLS PER MEASURE PERIOD parameter is set to 50 by default.
To determine which 50 grouped URLs should be displayed in the eG monitoring console, the eG BTM follows the below-mentioned logic:
- Top priority is reserved for URL groups with error transactions. This means that eG BTM first scans URL groups for error transactions. If error transactions are found in 50 URL groups, then eG BTM computes the aggregated response time of each of the 50 groups, sorts the error groups in the descending order of their response time, and displays all these 50 groups alone as the descriptors of this test, in the sorted order.
On the other hand, if error transactions are found in only one / a few URL groups – say, only 20 URL groups – then, eG BTM will first arrange these 20 grouped URLs in the descending order of their response time. It will then compute the aggregated response time of the transactions in each of the other groups (i.e., the error-free groups) that were auto-discovered during the same measure period. These other groups are then arranged in the descending order of the aggregated response time of their transactions. Once this is done, eG BTM will then pick the top-30 grouped URLs from this sorted list.
In this case, when displaying the descriptors of this test in the Layers tab page, the 20 error groups are first displayed (in the descending order of their response time), followed by the 30 ‘error-free’ groups (also in the descending order of their response time).
At any given point in time, you can increase/decrease the maximum number of descriptors this test should support by modifying the value of the MAX GROUPED URLS PER MEASURE PERIOD parameter.
