Hi @yurishkuro , I have modified the scripts to post the exclusion count. Currently I have integrated them with the format which we were already using. I tested all the scripts in the order which they are run in the CI and they are working fine in the local system. I got the output as below screenshot

from scripts/e2e/metrics_summary.sh which is used in CI https://github.com/jaegertracing/jaeger/actions/runs/20369773001/job/58533326928 to generate the summary that is to be posted.
But when I looked at the output of the run it was different from what i am getting as the exclusions are not counted. I am not sure why it is happening as i also inspected the diff artifacts from the E2E test run generated as output of the comparison in https://github.com/jaegertracing/jaeger/actions/runs/20369549009. The diffs are what i am getting while testing locally but the summary is mismatched. I am trying to investigate this.

Can you please have a look and suggest if i am missing something and also if i should change the comment format for exclusions?
Thanks.
