So we have an old application which have been running on production on
Tomcat7 for over 5 years and we tried to use the following configuration to
avoid excessive debug log but it seems not working:
akka {
loggers = ["akka.event.slf4j.Slf4jLogger"]
logging-filter = "akka.event.slf4j.Slf4jLoggingFilter"
loglevel = "DEBUG"
stdout-loglevel = "INFO"
jvm-exit-on-fatal-error = off
log-config-on-start = on
}
play {
akka {
loggers = ["akka.event.slf4j.Slf4jLogger"]
loglevel = "DEBUG"
logging-filter = "akka.event.slf4j.Slf4jLoggingFilter"
stdout-loglevel = "OFF"
}
}
On development, this works correctly but on production, this continue to
log debug hibernate messages to catalina.out which would generate very
large amount of log due to the feature we recently implemented that process
very large number of data at the same time. We also checked and logback
seems to be working correctly on Tomcat7 in production as the
application.log gets the correct log based on configuration below but Akka
somehow continue to send logs to catalina.out or stdout.
The application-logger.xml also contains the necessary codes to supposedly
stop hibernate debug logs from appearing but it seems not working:
<configuration>
<conversionRule conversionWord="coloredLevel"
converterClass="play.api.Logger$ColoredLevel" />
<appender name="FILE" class="ch.qos.logback.core.FileAppender">

The following environment variable are also set which they seem to be
working:
-Dlogback.configurationFile=application-logger.xml
-Dlogger.resource=application-logger.xml
-Dlogback.debug=true
We also checked and one option was to upgrade to Akka 2.4 but is there a
way to get rid of this debug log without having to upgrade first? The
application is quite old and we aren't ready to move to Java 8 yet.
Thanks
