Metric shows exit code 137 when the exit code is actually 0

[cherbst]

I experience a lot of alerts regarding the exit code 137 when services are re-deployed. When using docker inspect ... using the container name in container_attributes_name the output shows an exit code of 0 like here:

[

        "Id": "38be06a7263e4b06d9f38186f7425e8ad9ed3df77c7c2973f79fc02979cee3ca",
