According to the Spring documentation,
By default, the dm Server trace file
is called
$SERVER_HOME/serviceability/logs/dm-server/log_i.log
... The index i varies from 1 to 4, on
a rolling basis, as each log file
exceeds 10Mb.
I'm aware that the default trace file name can be changed in server.config. Is it possible to change the number of log files that are kept before rolling over and/or the maximum log file size? How?
Yes. Edit config/servicability.xml and restart the server. The Virgo (donation of dm Server to Eclipse.org) documentation gives some more detail.
The elements to edit are MaxIndex and MaxFileSize as shown in the extract below:
<appender name="${applicationName}_LOG_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>serviceability/logs/${applicationName}/log.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<FileNamePattern>serviceability/logs/${applicationName}/log_%i.log</FileNamePattern>
<MinIndex>1</MinIndex>
<MaxIndex>4</MaxIndex>
</rollingPolicy>
<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<MaxFileSize>10MB</MaxFileSize>
</triggeringPolicy>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<Pattern>[%d{yyyy-MM-dd HH:mm:ss.SSS}] %-28.28thread %-64.64logger{64} %X{medic.eventCode} %msg %ex%n</Pattern>
</encoder>
</appender>

I'm using imply to handle druid's cluster. But my logs files have increased to hundreds of gigabytes of storage. I'm talking about logs files present in imply/var/sv/ directory in which there are these 7 log files, broker.log, historical.log, middleManager.log zk.log, coordinator.log, imply-ui.log, and overlord.log.
Among them, this particular file called coordinator.log has increased to the really massive size of about 560 GBs in a matter of a few months. I have read all those logs, and they don't bother me much. What I'm concerned about is the size of the file which is eating my entire storage. I have tried finding ways to limit the size of those log files but believe me nothing worked for me.
I read in many places that druid uses log4j2 logger so we can limit the size using its configuration from log4j2.xml file. But again a big confusion there are four log4j2.xml files which one shall I modify?
I tried modifying all of them, but still, it didn't work. I'm kind of a fool while handling it seems like... Well so this is my request if anybody could point me in the right direction in limiting the size of these log files
You can setup a simple cron process to truncate these files periodically using truncate -s 0 imply/var/sv/*.log
The default log level in imply distribution is set to info which generates a lots of logs. If they don't bother you much, you can set the log level to error so that logs will be generated only when there is any error during system runtime. To set that, you need to modify logger level inside conf/druid/_common/log4j2.xml file.
<?xml version="1.0" encoding="UTF-8" ?>
<Configuration status="WARN">
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{ISO8601} %p [%t] %c - %m%n"/>
</Console>
</Appenders>
<Loggers>
<Root level="error">
<AppenderRef ref="Console"/>
</Root>
</Loggers>
</Configuration>
And even after do so, you should periodically truncate log files as #mdeora suggested.
The server.log says "signature_status": "UNVERIFIED". Is this a certificate issue?
Also what are the best ways to read the pingfederate logs in windows machine.
That sounds like an issue with signature verification, which could be the cert itself but is more likely a configuration issue. More information is really needed to know which it is.
I assume the issue you are having with reading logs on windows machines is because the files are large or are moving quickly. If the files are too big you can modify the log4j2.xml config file at appdir/pingfed*/pingfed*/server/default/conf/log4j2.xml to reduce the log size to something easier to read in notepad. Here is an example rolling file appender that should leave you with easily maneageable files.
<RollingFile name="FILE" fileName="${sys:pf.log.dir}/server.log"
filePattern="${sys:pf.log.dir}/server.log.%i" ignoreExceptions="false">
<PatternLayout>
<!-- Uncomment this if you want to use UTF-8 encoding instead
of system's default encoding.
<charset>UTF-8</charset> -->
<pattern>%d %X{trackingid} %-5p [%c] %m%n</pattern>
</PatternLayout>
<Policies>
<SizeBasedTriggeringPolicy
size="20000 KB" />
</Policies>
<DefaultRolloverStrategy max="5" />
</RollingFile>
If you issue is that the files are moving too fast to read then you might consider using something like baretail or Get-Content in powershell now that it has a tail switch.
following is my configration of log4j2:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="trace" name="MyApp" packages="com.swimap.base.launcher.log">
<Appenders>
<RollingFile name="RollingFile" fileName="logs/app-${date:MM-dd-yyyy-HH-mm-ss-SSS}.log"
filePattern="logs/$${date:yyyy-MM}/app-%d{MM-dd-yyyy}-%i.log.gz">
<PatternLayout>
<Pattern>%d %p %c{1.} [%t] %m%n</Pattern>
</PatternLayout>
<Policies>
<SizeBasedTriggeringPolicy size="1 KB"/>
</Policies>
<DefaultRolloverStrategy max="3"/>
</RollingFile>
</Appenders>
<Loggers>
<Root level="trace">
<AppenderRef ref="RollingFile"/>
</Root>
</Loggers>
</Configuration>
the issue is that each time when start up my service, a new log will be created even the old one has not reached the specific size. If the program restart frequently, i will got many log files end with ‘.log’ which never be compressed.
the logs i got like this:
/log4j2/logs
/log4j2/logs/2017-07
/log4j2/logs/2017-07/app-07-18-2017-1.log.gz
/log4j2/logs/2017-07/app-07-18-2017-2.log.gz
/log4j2/logs/2017-07/app-07-18-2017-3.log.gz
/log4j2/logs/app-07-18-2017-20-42-06-173.log
/log4j2/logs/app-07-18-2017-20-42-12-284.log
/log4j2/logs/app-07-18-2017-20-42-16-797.log
/log4j2/logs/app-07-18-2017-20-42-21-269.log
someone can tell me how can i append log to the exists log file when i start up my program? much thanks whether u can help me closer to the answer!!
I suppose that your problem it that you have fileName="logs/app-${date:MM-dd-yyyy-HH-mm-ss-SSS}.log in your log4j2 configuration file.
This fileName template means that log4j2 will create log file with name that contains current date + hours + minutes + seconds + milliseconds in its name.
You should probably remove HH-mm-ss-SSS section and this will allow you to have daily rolling file and to not create new file every app restart.
You can play with template and choose format that you need.
If you want only one log file forever - then create constant fileName, like fileName=app.log
It's not hard to implement this. There is a interface DirectFileRolloverStrategy, implement below method:
public String getCurrentFileName(RollingFileManager manager)
Mybe someone met same problem and this can help him.

I see next message for log record (in EventLog Analyzer):
local7:[13:32:45,763,SendingPool] Sending pool task executed. Pool size is [0
In WildFly 8.2.1 I have next configuration for handler:
<syslog-handler name="SYSLOG">
<level name="DEBUG"/>
<server-address value="localhost"/>
<facility value="local-use-7"/>
</syslog-handler>
Message:
1 2016-07-08T13:30:34.943+03:00 - java 910 com.mycompany.component.p - Sending pool task executed. Pool size is [0
How I can change message format for syslog?
Unfortunately there isn't a way using the syslog-handler to format the message. This was an oversight when it was created and there is a long standing JIRA to fix this.
However you can use a custom-handler and use a formatter.
/subsystem=logging/pattern-formatter=syslog-formatter:add(pattern="local7: [%d{hh:mm:ss,SSS},%c{1}] %s")
/subsystem=logging/custom-handler=syslog:add(class=org.jboss.logmanager.handlers.SyslogHandler, module=org.jboss.logmanager, named-formatter=syslog-formatter, properties={hostname="localhost", facility="LOCAL_USE_7", protocol="TCP", useCountingFraming=true})
/subsystem=logging/root-logger=ROOT:add-handler(name=syslog)
Note if you want the local7: to be printed that needs to be part of the format. There is not way to prepend the facility name to the message.
Looking at:
1 2016-07-08T13:30:34.943+03:00 - java 910 com.mycompany.component.p - Sending pool task executed. Pool size is [0
That looks like the raw message minus the priority. By default the syslog handler will use the RFC 5424 format. If you want to use RFC 3164 add syslogType=RFC3163 to the properties attribute in the above custom-handler add operation and remove the useCountingFraming=true. Note the useCountingFraming=true may need to removed anyway. It depends on your syslog server setup.
I have a small test in which I am trying to chalk out the time taken by Infinispan in a local cache and then in a local cache with a write behind.
Surprisingly, the time taken in a local cache to put 8M entries is around 27 sec and to do a get it is 1 millisec. That is good. However, as soon as I enable the write behind the does not even end in 30 minutes. I am sure there is something which is terribly wrong with the configuration.
I have used 5.3.0 Final and 5.2.7 final.
The configurations are pasted here
<namedCache name="LocalWithWriteBehind">
<loaders shared="false">
<loader class="org.infinispan.loaders.file.FileCacheStore"
fetchPersistentState="true" ignoreModifications="false"
purgeOnStartup="false">
<properties>
<property name="location" value="${java.io.tmpdir}" />
</properties>
<!-- write-behind configuration starts here -->
<async enabled="true" threadPoolSize="500" />
<!-- write-behind configuration ends here -->
</loader>
</loaders>
</namedCache>

The file cache store before Infinispan 6.0 was very slow. Please upgrade to Infinispan 6.0.0.Final, and enable the single file cache store as indicated here.
