Subject: [logback-user] migration from log4j to logback. help with specific
 log4j.xml property (CronTriggerPolicy>
Message-ID: <CADML7kduYkhP=MQXz_jgJTs9NMX2B-PYSFzYRAUat4WbPPstOQ@mail.gmail.com>

Hello
 I am trying to migrate a application form log4j to logback. I do have the
following property defined in the existing log4j2.xml file, I do not see
any such equivalent in the logback.xml.
*How do I specify something like a CronTriggerPolicy as shown below?*
Any help would be appreciated.

log4j2.xml

<RollingFile name="myLog" fileName="app.log"
filePattern"app.log.%d{yyyyMMdd_HHmmzz}Z.log>
<Policies>
*     <CronTiggerPolicy schedule="0 0 * * 1 ?" evaluateOnStartup="true">*
    <SizeBasedTriggerPolicy size="10MB"/>
</Policies>
</RollingFile>


Best regards
Ani

Hi Ani,

Logback does not support cron-like triggering. However, it supports
triggering based on a date pattern, e.g "yyyy-MM-dd"

The schedule "0 0 * * 1 ?" corresponds to first day of the week at
midnight. The pattern "yyyy-ww" corresponds to the same triggering
schedule.

The link below provides more details:

I hope this helps,

Hello
 Thanks for the answer. I am still a bit confused.
If the logback FileNamePattern is "app.log.%d{yyyyMMdd_HHmmss}Z.log", would
this by default mean its going to rollover every second? In other words ,
does the fileNamePattern define the rollover schedule?

You mention using "yyyy-ww"  to trigger a weekly Rollover, would this mean
the fileName pattern should be made
"app.log%d{yyyy-ww}Z.log" ?

Is it possible to decouple the Name of the Rolled over log file and the
tiriggering of RollOver ?  What if  Iwant a rollover every week , but the
name of the Rolled Over file to have hhmmss as part of it? I Sorry if I
have caused confusion here

Best Regards
Ani

That is correct, the fileNamePattern defines the rollover schedule.

Yes. However, automatic file compression is enabled if the value of the
fileNamePattern option ends with .gz or .zip but not Z.

Complete decoupling is not possible however you can have multiple %d
specifiers. See the link provided earlier.

Subject: [logback-user] Xml to Java code, logstash encoder
Message-ID: <CALCJffXaJow7m0KveKN5NRnmx_1WKBwz3X1fDZzicxqoscuatw@mail.gmail.com>

Hello Guys


I want to create the logstash encoder you see in xml with Java code.  But
there is no method to set the pattern.  Which method should I do?

<appender name="STASH"
class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>logback/uptLog.log</file>
    <rollingPolicy
class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>logback/uptLog.%d{yyyy-MM-dd}.log</fileNamePattern>
    </rollingPolicy>
    <encoder class="net.logstash.logback.encoder.LogstashEncoder">
        <charset>UTF-8</charset>
        <pattern>
            %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %-5level %logger{36} -
%X{requestId} %msg%n%exception{full}
        </pattern>
    </encoder>
</appender>



net.logstash.logback.encoder.LogstashEncoder logstashEncoder = new
LogstashEncoder();
logstashEncoder.setContext(loggerContext);
logstashEncoder.start();

Subject: [logback-user] Help with FileName and FilePAttern syntax:
Message-ID: <CADML7kdXpi3+ajzR4xi853deYDHTFdU4ZwPwzv-v7Ovm5vF1YA@mail.gmail.com>

Hello
 I am trying to migrate from log4j2 to logback. I am trying to find
equivalent syntax for filename and filepatterns in this case

log4j2.xml
<RollingFile name="myLOg"
*fileName="/log/${env1}-{{*myEnv|||@mydir@*}}-app.log"*  .../>

When i use something like this I get an exception saying invalid Repition.
I m not sure what the above code was intended to do.

1. How can i convert this fileName to a valid one in logback ?
2. I do understand it will resolve ${env1} properly from environment
variables. The "myENv" is being defined in a .properties file being loaded
by the application. I have seens examples in logback.xml like

<RollingFile name="myLOg" *fileName="/log/${env1}-:[myEnv]-app.log"*  .../>

what* does the :[myEnv] do here ? Would it resolve to a property set in a .*
properties* file?*

*ALso not sure what the @ symbol means in the log4j, and if it has any
equivalent here?*

thanks for any pointers

Best Regards
Ani
