keptn_app_deploymentinterval: 9.223372036854776e+09

Hi!

In my DORA grafana dashboard I get this huge number which skews my whole panel.

Checking more closely on keptn.svc.something:2222/metrics I find this

keptn_app_deploymentinterval{keptn_deployment_app_name="my-app",keptn_deployment_app_namespace="my-app",keptn_deployment_app_previousversion="2449103969",keptn_deployment_app_version="924330662",otel_scope_name="keptn/task",otel_scope_version=""} 9.223372036854776e+09

The number 9.2233... is the same as 2^63 which makes me think there is some kind of integer overflow? Not sure what caused this, but I believe I reverted to a previous deployment and when looking at the calculation between the versions it became 292 years.

For now I just exclude numbers bigger than "1000000000 seconds".

By changing the dashboard from

"expr": "avg by(keptn_deployment_app_previousversion, keptn_deployment_app_version) (keptn_app_deploymentinterval{keptn_deployment_app_name=\"$Application\"})",

to

"expr": "avg by(keptn_deployment_app_previousversion, keptn_deployment_app_version) (keptn_app_deploymentinterval{keptn_deployment_app_name=\"$Application\"} < 1000000000)",

Thanks! I'll use the same condition for now
