Issue/Introduction

Modifying the daemon.log to have 5 rollover logs instead of 10 which is by default.

Environment

All NCM versions

Resolution

**Please note in doing this change it will require a restart of all the services (systemctl restart vcmaster) on the Application Server. Please cancel or stop all jobs before making the changes.**

1. Log into the CLI of the Application Server with 'root' access. 

2. Run the below to set environmental variable:

 source /etc/voyence.conf 

 
3. Make a backup copy of the log4j.xml file as below:

cp $VOYENCE_HOME/cm/daemon/conf/log4j.xml $VOYENCE_HOME/cm/daemon/conf/bkup_log4j.xml

4. Edit the file:

vi $VOYENCE_HOME/cm/daemon/conf/log4j.xml

5. Search for the following section:

<appender name="FILE" class="org.apache.log4j.RollingFileAppender">
        <param name="File" value="$VOYENCE_HOME/logs/daemon.log"/>
        <param name="Append" value="true"/>
        <param name="MaxBackupIndex" value="10"/>

6. In the line <param name="MaxBackupIndex" value="10"/> change the value="10" to value="5"

7. Save and close the file.

8. Perform a service restart:

systemctl restart vcmaster

 

NOTE: Earlier created daemon logs 6 thru 10 (daemon.6.log thur daemon.10.log) will still be available under $VOYENCE_HOME/logs directory, but NCM won't be creating or writing to them. Delete them manually to clear up the disk space.
