Hello, I am trying to manage logs better with flink, but I would need some help. I think the information on the docs is a bit scarce in terms of logging as there is not much information on how to configure the different environments. Currently I am trying to add proper logging to my tests. I am running flink 1.13.2
By going to github, I copy/pasted the approach used in flink-tests. In my test/resource I have created a file named log4j2-test.properties and put the contents copy/pasted from here: https://github.com/apache/flink/blob/release-1.13/flink-tests/src/test/resources/log4j2-test.properties The only thing I have changed is "rootLogger.level = OFF" to "rootLogger.level = WARN" as I'd like to see WARN (and above) log messages. In my tests I use the MiniClusterWithClientResource as a @ClassRule as described here: https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/dev/datastream/testing/#testing-flink-jobs My tests work fine and so does the logging, but I also see this a lot in my logs: 2298 [main] WARN org.apache.flink.runtime.webmonitor.WebMonitorUtils [] - Log file environment variable 'log.file' is not set. 2302 [main] WARN org.apache.flink.runtime.webmonitor.WebMonitorUtils [] - JobManager log files are unavailable in the web dashboard. Log file location not found in environment variable 'log.file' or configuration key 'web.log.path'. 2533 [main] WARN org.apache.flink.runtime.webmonitor.WebMonitorUtils [] - Log file environment variable 'log.file' is not set. 2533 [main] WARN org.apache.flink.runtime.webmonitor.WebMonitorUtils [] - JobManager log files are unavailable in the web dashboard. Log file location not found in environment variable 'log.file' or configuration key 'web.log.path'. which obviously is not ideal since it bloats the logging console. How can I prevent this message being logged for every test? I can also provide a SSCCE if needed. Regards , Nikola
