It's not unusual for this warning to be logged.
You could always disable logging from the WebMonitorUtils:
logger.wmu.name = org.apache.flink.runtime.webmonitor.WebMonitorUtils
logger.wmu.level = off

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
<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
<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

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.
