Hi Members,

 

I wanted to check if we can update any config file so that the SAS Studio mid tier logs are rolled over based on the file size. The log grows at a tremendous pace and would like to ensure that we keep an eye on its size. It is present under

<sas config>/Lev1/Web/Logs/SASServer2*/SASStudioMidTier.log

 

Thanks in advance,

SK

I believe there is no documentation about it in documentation.sas.com ( http://documentation.sas.com/?docsetId=logug&docsetTarget=p0vt6dps7nzkbgn0zntzi3qs3a0d.htm&docsetVer... ), however this system is based on a broadly commonly used Log4J and Apache.

Hello @shirishkamath,

 

not the workspace server logs, but "sas/config/Lev1/Web/Common/LogConfig/SASStudio-log4j.xml"

 

You are looking for to un-comment the rolling appended functions

 

  <!-- A time/date based rolling appender
    <appender class="org.apache.log4j.DailyRollingFileAppender" name="SAS_FILE">
        <param name="datePattern" value="'.'yyyy-MM-dd"/>
        <param name="append" value="true"/>
        <param name="file" value="${config.lev.web.appserver.logs.dir}/SASStudioMidTier3.4.log"/>
        <layout class="com.sas.svcs.logging.CustomPatternLayout">
            <param name="ConversionPattern" value="%d [%t] %-5p [%u] %c - %m%n"/>
        </layout>
    </appender>
    -->

Thanks Juan. This helps. But can you also let me know what changes do I need to make in order to roll over the logs based on size? Looks like this piece will roll over the log based on time stamp?

Hi @JuanS_OCS ,

 

On .../config/Lev1/Web/Common/LogConfig there is a config file for each components on my web server. There is any way to change make this change to all (general config file) or I need to change one by one?
