ysjjovo edited a comment on issue #4409: Log lost in method 'KubernetesRestLogSourceStage.readLines' URL: https://github.com/apache/incubator-openwhisk/issues/4409#issuecomment-485694092 You're right,Fetching K8S HTTP Logs with parameter sinceTime may get additional logs,sample debug log below show this. ``` [2019-04-22T10:02:43.648Z] [DEBUG] *** Fetching K8S HTTP Logs w/ Path: /api/v1/namespaces/***/pods/wskinvoker-00-5-log-lost-test/log Query: timestamps=true&sinceTime=2019-04-22T09:55:02.893115523Z [2019-04-22T10:02:43.666Z] [DEBUG] * Read & decoded lines for K8S HTTP: List(2019-04-22T09:55:02.885279349Z stdout:AAAAA, 2019-04-22T09:55:02.893040214Z stdout: XXX_THE_END_OF_A_WHISK_ACTIVATION_XXX, 2019-04-22T09:55:02.893115523Z stdout: XXX_THE_END_OF_A_WHISK_ACTIVATION_XXX) ``` In this situation,field lastTimeStamp will always be set to 2019-04-22T09:55:02.893115523Z,then all invocation will get the same log. So we should filter it manually,but docker json log field don't produce 9 digit nanosecond all the time,this will make this filter filt some normal logs for mistake.
