@CarloWakefield I faced same issue so i added console appender after that i can able to see log entries. can you try that ? if it is works for you.

<configuration>
    <appender name="CLOUD" class="com.google.cloud.logging.logback.LoggingAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>DEBUG</level>
        </filter>
    </appender>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
    </appender>
    <root level="debug">
        <appender-ref ref="CLOUD"/>
        <appender-ref ref="STDOUT"/>
    </root>
</configuration>

OK, I will try it.
But should this be necessary? Shouldn't the com.google.cloud.logging.logback.LoggingAppender appender already do the logging?
And if not, why isn't this documented at https://cloud.google.com/logging/docs/setup/java#logback_appender_for?

Facing the same issue as well and confused regarding the proper setup here

Also have this same issue. In my case running a container on Cloud Run.

Same issue here.

For me, the logs are written to Stackdriver, but in an unexpected location.
I see com.google.cloud.logging.logback.LoggingAppender messages in
GKE Container -> application.log

ch.qos.logback.core.ConsoleAppender messages are in the expected location:
Kubernetes Container -> stdout

The GKE Cluster version is 1.15 so logs should be written to Kubernetes not GKE.

[AWinterman]

the documentation does not make clear that the log value in the logback.xml conf is what determines the gcloud logging logName. Might be good to call that out more explicitly.

I am deeply apologies that this issue was neglected for so long. Does anyone still experience a problem to ingest logs into Google Cloud Logging using Logback?

[minherz]

I close the issue due to lack of response. Feel free to reopen it if the describe problem is still relevant.

[sefaYavuz]

I'm facing this issue as well @minherz

[nupur1124N]
