service.failurerate metric not returning values in Dynatrace 176

[grabnerandi]

It seems there is a problem with Dynatrace API returning values for the service.failurerate measure. This problem was introduced in Dynatrace Version 176. Its already known by Dynatrace and it will be fixed.
In case you run into this problem which manifests itself as Pitometer not being able to retrieve values for the service.failurerate measure you can workaround this by using the serivce.serversidefailurerate measure instead. This provides the same metric value
