upgle commented on issue #4768: Update kamon-core, instrumentations and reporters to 2.0.x. URL: https://github.com/apache/openwhisk/pull/4768#issuecomment-569208515 I've found the reason. The [host metrics module](https://kamon.io/docs/latest/instrumentation/system/host-metrics/#available-metrics) was not explicitly disabled in the 2.x version. ### Legacy configuration (1.x) The following configuration is no longer supported. It should be removed https://github.com/apache/openwhisk/blob/b26101b8dc0d7a2f48995cd81f12d5b2db10be46/common/scala/src/main/resources/application.conf#L84 ``` system-metrics { # disable the host metrics as we are only interested in JVM metrics host.enabled = false } ``` ### Latest version configuration (2.0.x) To disable host metrics in the latest version, below configuration should be added ``` kamon.modules { host-metrics { enabled = no } } ``` #### Reference https://kamon.io/docs/latest/instrumentation/system/host-metrics/#disabling-the-module
