Using Log4J2 2.8 (via the 1.2 API Bridge) for Tomcat8 Internal Logging - RollingFileAppender does not (cannot?) create new Log File

Ankit Agarwal
Hi,

I’m using Log4J2 (2.8) via the 1.2 API Bridge for Tomcat 8 internal logging.

I followed the instructions here: https://tomcat.apache.org/tomcat-8.0-doc/logging.html#Using_Log4j <https://tomcat.apache.org/tomcat-8.0-doc/logging.html#Using_Log4j>
- With the exception that I also copied the Bridge JAR into the Tomcat8 lib directory

I have configured Log4J2 with this XML file

<?xml version="1.0" encoding="utf-8"?>
<Configuration status="info">
     <Properties>
          <Property name="logDirectory">${sys:catalina.base}/logs</Property>
          <Property name="systemName">CMS</Property>
          <Property name="componentName">Tomcat</Property>
          <Property name="serverIpAddress">${env:PUBLIC_IP_ADDRESS}</Property>
          <!-- <Property name="layout">%d [%t] %-5p %c- %m%n</Property> -->
          <Property name="layout">%d{DATE} "%d{ISO8601}" "${systemName}" "${componentName}" "%X{clientIpAddress}" "%X{clientTcpPort}" "%X{username}" "%X{sessionId}" "%X{sessionAuthenticationId}" "%X{sessionAuthenticationToken}" "${serverIpAddress}" "%T" "%t" "%X{apiName}" "%X{apiSystemActionType}" "%X{apiSystemItemType}" "%x" "%l" "%p" "%m"%n%n</Property>
     </Properties>
     <Appenders>
          <Console name="CONSOLE" target="SYSTEM_OUT">
               <PatternLayout pattern="${layout}"/>
          </Console>
          <RollingFile name="CATALINA" fileName="${logDirectory}/catalina.log" filePattern="${logDirectory}/catalina-%i.log.gz">
               <PatternLayout pattern="${layout}"/>
               <Policies>
                    <SizeBasedTriggeringPolicy size=“100 MB" />
               </Policies>
               <DefaultRolloverStrategy max="20" />
          </RollingFile>
          <RollingFile name="LOCALHOST" fileName="${logDirectory}/localhost.log" filePattern="${logDirectory}/localhost-%i.log.gz">
               <PatternLayout pattern="${layout}"/>
               <Policies>
                    <SizeBasedTriggeringPolicy size="100 MB"/>
               </Policies>
               <DefaultRolloverStrategy max="20" />
          </RollingFile>
          <RollingFile name="MANAGER" fileName="${logDirectory}/manager.log" filePattern="${logDirectory}/manager-%i.log.gz">
               <PatternLayout pattern="${layout}"/>
               <Policies>
                    <SizeBasedTriggeringPolicy size="100 MB"/>
               </Policies>
               <DefaultRolloverStrategy max="20" />
          </RollingFile>
          <RollingFile name="HOST-MANAGER" fileName="${logDirectory}/host-manager.log" filePattern="${logDirectory}/host-manager-%i.log.gz">
               <PatternLayout pattern="${layout}"/>
               <Policies>
                    <SizeBasedTriggeringPolicy size="100 MB"/>
               </Policies>
               <DefaultRolloverStrategy max="20" />
          </RollingFile>
     </Appenders>
     <Loggers>
          <Root level="info">
               <AppenderRef ref="CATALINA"/>
          </Root>
          <Logger name="org.apache.catalina.core.ContainerBase.[Catalina].[localhost]" level="info" additivity="false">
               <AppenderRef ref="LOCALHOST"/>
          </Logger>
          <Logger name="org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager]" level="info" additivity="false">
               <AppenderRef ref="MANAGER"/>
          </Logger>
          <Logger name="org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager]" level="info" additivity="false">
               <AppenderRef ref="HOST-MANAGER"/>
          </Logger>
     </Loggers>
</Configuration>


All 4 RollingFile Appenders are configured identically (except for the log filename).

The problem I’m running into is that when the SizeBasedTriggeringPolicy is executed, the current log file is zipped. However, a new log file is not created.

As a result, the Tomcat8 stops logging.

If I restart Tomcat8, then a new file is created and the Tomcat8 functions normally, but only until this new log file reaches its limit and is zipped up. Then once again, the problem repeats itself.

Does the 1.2 API Bridge not support the SizeBasedTriggeringPolicy?

Do I have any options other than restarting the Tomcat8? Will the TimeBasedTriggeringPolicy work and is that my only option?

Since the Log4J2 being used in Tomcat8 has no problem creating the required files on restart, I don’t think its a permissions issue.

I’d appreciate any thoughts and pointers.

Thanks,
Ankit

If you enable internal Log4j2 logging with <Configuration status ="trace"> at the top of your configuration, then you should see internal Log4j2 logging on the console.
It should show details of what happens during a rollover. Can you post that output?

My original hypothesis was wrong. The problem does not arise during a rollover.

Here is what I have found so far. I see this behavior on my development machine.
I did not use the Tomcat 8 installation for the entire weekend, i.e., 2 days or so. Did not use means that I did not visit my web application via a browser, did not deploy a new WAR, did not restart Tomcat, etc. I just left it running as is.
Sometime during the weekend, Tomcat zipped up my log files - catalina.out, localhost.log, manager.log, and even my web applications own log file which is written to a sub-directory of "/var/log/tomcat8".
From the zip file timestamps it looks like this was approximately 24 hours after I last used Tomcat.
Once the zip files were created, replacement log files were not created.
Now, when I visit the web application via a browser, no logs are written (as there is no log file). No error is added to "catalina.out" either. It is 0 bytes since the last catalina.out file was zipped up.
If I try to redeploy my WAR, it fails and there is no error in the Tomcat Admin Manager UI - this is because the localhost.log file has been zipped and a new one has not been created. If I restart the Tomcat, this problem will go away.

Interestingly, the catalina.log file does not have this problem, and I believe it is because I have the TRACE level logging enabled as you had suggested. So Tomcat is writing logs to catalina.log every second (even when it is idle).
Given all this, the only logs I have are from the catalina.log file and they are of this type:
18 Apr 2017 16:35:23,472 "2017-04-18T16:35:23,472" "CMS" "Tomcat" "" "" "" "" "" "" "52.25.59.238" "59" "http-nio-443-ClientPoller-1" "" "" "" "[]" "org.apache.tomcat.util.net.NioEndpoint$Poller.timeout(NioEndpoint.java:1318)" "TRACE" "timeout completed: keys processed=0; now=1492558523472; nextExpiration=1492558523471; keyCount=0; hasEvents=false; eval=false"
18 Apr 2017 16:35:23,904 "2017-04-18T16:35:23,904" "CMS" "Tomcat" "" "" "" "" "" "" "52.25.59.238" "54" "ContainerBackgroundProcessor[StandardEngine[Catalina]]" "" "" "" "[]" "org.apache.catalina.startup.HostConfig.checkResources(HostConfig.java:1249)" "DEBUG" "Checking context[] redeploy resource /var/lib/tomcat8/webapps/ROOT.war"

It seems that Tomcat (or Log4J/Log4J2) automatically zips up log files after inactivity of 24 hours or so and fails to create replacement log files.

Any thoughts on this? Has you seen this kind of behavior before?

Thanks,Ankit

Re: Using Log4J2 2.8 (via the 1.2 API Bridge) for Tomcat8 Internal Logging - RollingFileAppender does not (cannot?) create new Log File

I didn't think it was possible to use Log4j2 for tomcat container logging. I thought they implemented a custom extension of Java util logging to prevent application logging issues to interfere with the container. But I could be wrong.

>> All 4 RollingFile Appenders are configured identically (except for the log filename).
>>
>> The problem I’m running into is that when the SizeBasedTriggeringPolicy is executed, the current log file is zipped. However, a new log file is not created.
>>
>> As a result, the Tomcat8 stops logging.
>>
>> If I restart Tomcat8, then a new file is created and the Tomcat8 functions normally, but only until this new log file reaches its limit and is zipped up. Then once again, the problem repeats itself.
>>
>> Does the 1.2 API Bridge not support the SizeBasedTriggeringPolicy?
>>
>> Do I have any options other than restarting the Tomcat8? Will the TimeBasedTriggeringPolicy work and is that my only option?
>>
>> Since the Log4J2 being used in Tomcat8 has no problem creating the required files on restart, I don’t think its a permissions issue.
>>
>> I’d appreciate any thoughts and pointers.

>> Thanks,
