The product I work on has many docker microservices in addition to docker Zookeeper v3.6.2
The envops team has a logstash parser which requires a specific date/time format (and a couple other items) that requires me to modify the ConversionPattern in the log4j.properites file. My question is if changing the pattern will cause issues in the future if I need to open a Jira zookeeper item and attach the logs for diagnosing the issue? Below are my change to the ConversionPattern for the date/time format and the ZK server ID along with an example log message from the Linux /var/log/docker-containers.log file: /conf/log4j.properties Before my changes: log4j.appender.CONSOLE.layout.ConversionPattern=*%d{ISO8601} [myid:%X{myid}]* - %-5p [%t:%C{1}@%L] - %m%n Feb 5 23:00:06 ng02wdc01azoo01 [docker][8abd469f1349][zookeeper_zoo1_1][docker-registry.ite.idng.ibmcloudsecurity.com:5000/zookeeper:Rel_127][1208]: *2021-02-05 23:00:06,200 [myid:1]* - INFO [CommitProcessor:1:LearnerSessionTracker@116] - Committing global session 0x1005c0d69644a60 After my changes: log4j.appender.CONSOLE.layout.ConversionPattern=*[%d{MM/dd/yyyy HH:mm:ss:SSS} UTC] myid-%X{myid}* - %-5p [%t:%C{1}@%L] - %m%n Feb 5 22:58:00 ng10wdc01azoo01 [docker][e704c73ec8b0][zookeeper_zoo1_1][docker-registry.dev.idng.ibmcloudsecurity.com:5000/zookeeper:Dev_357][1204]: *[02/05/2021 22:58:00:708 UTC] myid1* - INFO [CommitProcessor:1:LeaderSessionTracker@104] - Committing global session 0x30040af98ec1bde -- Sent from: http://zookeeper-user.578899.n2.nabble.com/
