Description of problem: After installing OCP 3.4 I see lots of unhelpful messages being logged in system log, for example this is being logged every 10 seconds (!): Feb 6 10:24:35 infra01 atomic-openshift-node: I0204 10:24:35.999002 4959 conversion.go:133] failed to handle multiple devices for container. Skipping Filesystem stats This comes up also quite often: Feb 6 11:04:13 infra01 systemd: Scope libcontainer-32749-systemd-test-default-dependencies.scope has no PIDs. Refusing. And also: Feb 6 11:07:20 node01 atomic-openshift-node: I0204 11:07:20.453234 23617 reconciler.go:299] MountVolume operation started for volume "kubernetes.io/secret/f427dfb5-eb44-11e6-a750-525400dbbcb2-hawkular-metrics-client-secrets" (spec.Name: "hawkular-metrics-client-secrets") to pod "f427dfb5-eb44-11e6-a750-525400dbbcb2" (UID: "f427dfb5-eb44-11e6-a750-525400dbbcb2"). Volume is already mounted to pod, but remount was requested. And still: Feb 6 11:03:15 infra01 atomic-openshift-node: I0204 11:03:15.030854 23867 node_auth.go:143] Node request attributes: namespace=, user=&user.DefaultInfo{Name:"system:serviceaccount:openshift-infra:heapster", UID:"f67c12c5-eb44-11e6-a750-525400dbbcb2", Groups:[]string{"system:serviceaccounts", "system:serviceaccounts:openshift-infra", "system:authenticated", "system:authenticated"}, Extra:map[string][]string{}}, attrs=authorizer.DefaultAuthorizationAttributes{Verb:"create", APIVersion:"v1", APIGroup:"", Resource:"nodes/stats", ResourceName:"infra01.example.com", RequestAttributes:interface {}(nil), NonResourceURL:false, URL:"/stats/container/"} Feb 6 11:03:15 infra01 atomic-openshift-node: I0204 11:03:15.045958 23867 server.go:971] POST /stats/container/: (15.285129ms) 200 [[Go-http-client/1.1] 10.1.1.4:55070] These probably should not be logged on default log level (debug might be more appropriate) and it might be also considered to use a dedicated log file for these. There might be other cases as well which I didn't come across now, would be great to have OCP logging reviewed and sanitized in general. If done in upstream already, then please consider backporting to RHEL 7 / OCP 3.x. It could be some of the messages, like the systemd one above, are not coming directly from OCP components but a holistic view would helpful here so that after installation an idle system should not log much. Please adjust the BZ Component as needed. Version-Release number of selected component (if applicable): OCP 3.4
