Redirect log4j output from the database

As listed in Log4j files, some log output is directed to both the xferlog file and the database.

If you set any log level to debug or all, SecureTransport produces many log messages which can overload the database. Do not log to the database for log level debug or all.

Note When server log messages are stored in the database, they are displayed in the Server Log page. When you store the log messages in a file, they are not displayed in the Server Log page.

To direct the log messages being stored in the database to a file, modify the ServerLog appender for each relevant file. The example uses FILEDRIVEHOME instead of <FILEDRIVEHOME> to represent the SecureTransport installation directory to avoid confusion with the syntactic use of pointed brackets in XML. Replace the <FILEDRIVEHOME> with the actual installation path to the SecureTransport home folder in the XML configuration file.

Change:

<STDBAppender name="ServerLog" locationInfo="true" maxLoggingEventQueueSize="10000" fallbackLogger="ServerLogFallback" databaseStatusCheckupDelay="60" databaseCheckupTimeout="30" idAreaBegin="-210000000000" idAreaEnd="-110000000000" driverClass="org.mysql.jdbc.Driver" initialPoolSize="30" (for AIX) driverClass="org.mariadb.jdbc.Driver" initialPoolSize="30" (for OS other than AIX)

maxPoolSize="100" minPoolSize="30" acquireIncrement="7" maxStatements="4000">

      <Filters>

         <STLog4JNDCFilter componentName="TM" onMatch="NEUTRAL" onMismatch="DENY"/>

      </Filters>

</STDBAppender>

Note The dataSource settings are different for each configuration file.

To:

<DailyRollingFileAppender name="ServerLog" fileName="FILEDRIVEHOME/var/logs/tm.log" append="true" rotateDirectory="FILEDRIVEHOME/var/db/hist/logs/" datePattern="'.'yyyy-MM-dd">

      <PatternLayout pattern="%d{ISO8601} [%t] %p %c %equals{%x}{[]}{} - %m%n%ex"/> </DailyRollingFileAppender>

Note If the Server log messages are stored in a file (and it is using the DailyRollingFileAppender), rotation will be handled by the log4j files.

For example, if the File option is set to /foo/bar.log and the DatePattern set to '.'yyyy-MM-dd, on 2020-02-16 at midnight, the logging file /foo/bar.log will be copied to /foo/bar.log.2020-02-16 and logging for 2020-02-17 will continue in /foo/bar.log until it rolls over the next day.

In the admin-log4j.xml file there is an additional appender called AuditLogAppender. Change appender from:

<STDBAppender name="AuditLogAppender" locationInfo="true" maxLoggingEventQueueSize="10000" fallbackLogger="ServerLogFallback" databaseStatusCheckupDelay="60" databaseCheckupTimeout="30" idAreaBegin="-40000000000" idAreaEnd="-30000000000" driverClass="org.mysql.jdbc.Driver" initialPoolSize="5" (for AIX) driverClass="org.mariadb.jdbc.Driver" initialPoolSize="5" (for OS other than AIX)

maxPoolSize="25" minPoolSize="5" acquireIncrement="5" maxStatements="4000"

      <Filters>

         <STLog4JNDCFilter componentName="AUDIT" onMatch="NEUTRAL" onMismatch="DENY"/>

      </Filters>

</STDBAppender>

To:

<DailyRollingFileAppender name="AuditLogAppender" fileName="FILEDRIVEHOME/var/logs/admin/audit-menu.log" append="true" rotateDirectory="FILEDRIVEHOME/var/db/hist/logs/admin" datePattern="'.'yyyy-MM-dd">

      <PatternLayout pattern="%d{ISO8601} [%t] %p %c %equals{%x}{[]}{} - %m%n%ex"/>

</DailyRollingFileAppender>
