In the dashboard I can see a succeeded deploy from aplication GLE in environment PROD
But in the deployment by environment report that succeded deploy doesn't exists
I chose all the environments and all the processes of the application
We make statistics and metrics based on that report and now it seems that it was not reliable.
What could be the reason why some deploys do not appear?
I checked the behavior in house, but I could not reproduce your situation which succeeded deployment was counted as failure.
However, the counter of both success/fail was reset when the deployment was failed, despite only succeeded deployments can be counted properly. I guessed the counter is missing if deployment is duplicated with same application, process and environment.
So, I think it is unexpected behavior.
I recommend to open a support case to investigate further.
On the other hand, I'm not sure, but you may be able to find the expected data in statistics_counters table in database as work around.
