In rare cases, scatterplot data points for two different metrics can "overlap". The Catchpoint scatterplot chart currently does not have millisecond granularity. As a result, it will perform data aggregation & average the statistics from two runs, which can result in identical values for different metrics.
For example, consider the following hypothetical test data:
Run #1
- DNS - 4ms
- Connect - 2ms
- SSL - 22ms
Run #2
- DNS - 0ms
- Connect - 2ms
- SSL - 89ms
In this situation, the resulting scatterplot will average the runs, resulting in the following averaged values:
- DNS - 2ms
- Connect - 2ms
- SSL – 55ms
As stated, this should only occur in rare cases. If this is happening consistently in your Catchpoint performance charting, please contact Catchpoint support.
