Disable-the-platform-access-logs-and-most-of-service-logs-on-EU8-for-farm-stabilization_686074621

Introduction

The farm is down due to high I/O activity. To work around this issue, disable the platform access and service logs on EU8.

The scenario to be addressed involves a platform high thread issue caused by excessive log writes. This situation will not trigger a platform restart but has the potential to bring down the entire farm as the platform becomes unresponsive due to an accumulation of pending threads.
This is a farm-level task.

It will keep the log level of the following packages as INFO:

com.hp.maas.platform.services.workflow

com.hp.maas.platform.ems

com.hp.maas.platform.services.notification

com.hp.maas.platform.services.notificationhistory

com.hp.maas.platform.services.mail

Required steps

1. Create a patch file named platform-patch.yaml with the following content.

   spec:
     template:
       spec:
         containers:
           - name: itom-xruntime-platform
             startupProbe:
               periodSeconds: 30
               timeoutSeconds: 60
               failureThreshold: 60
               initialDelaySeconds: 120
               exec:
                 command:
                   - sh
                   - -c
                   - |
                     sed -i "5s/value=\"INFO\"/value=\"OFF\"/" /opt/apache-tomcat/webapps/platform-webapp/WEB-INF/classes/logback.xml &&
                     sed -i "s/<Valve className=\"com.microfocus.maas.platform.runtime.CustomAccessLog\"/<\!-- <Valve className=\"com.microfocus.maas.platform.runtime.CustomAccessLog\"/" /opt/apache-tomcat/conf/server*.xml &&
                     sed -i "s/OUTGOING_ITEM_COUNT}r \"\/>/OUTGOING_ITEM_COUNT}r \"\/> -->/" /opt/apache-tomcat/conf/server*.xml &&
                     sed -i "s/<logger level=\"\${logger.defaultThreshold}\" name=\"com.hp.maas.platform.services.workflow\">/<logger level=\"INFO\" name=\"com.hp.maas.platform.services.workflow\">/g"  /opt/apache-tomcat/webapps/platform-webapp/WEB-INF/classes/sync/log-platform-base.xml &&
                     sed -i "s/<logger level=\"\${logger.defaultThreshold}\" name=\"com.hp.maas.platform.ems\">/<logger level=\"INFO\" name=\"com.hp.maas.platform.ems\">/g" /opt/apache-tomcat/webapps/platform-webapp/WEB-INF/classes/sync/log-platform-base.xml &&
                     sed -i "s/<logger level=\"\${logger.defaultThreshold}\" name=\"com.hp.maas.platform.services.notification\">/<logger level=\"INFO\" name=\"com.hp.maas.platform.services.notification\">/g" /opt/apache-tomcat/webapps/platform-webapp/WEB-INF/classes/sync/log-platform-base.xml &&
                     sed -i "s/<logger level=\"\${logger.defaultThreshold}\" name=\"com.hp.maas.platform.services.notificationhistory\">/<logger level=\"INFO\" name=\"com.hp.maas.platform.services.notificationhistory\">/g" /opt/apache-tomcat/webapps/platform-webapp/WEB-INF/classes/sync/log-platform-base.xml &&
                     sed -i "s/<logger level=\"\${logger.defaultThreshold}\" name=\"com.hp.maas.platform.services.mail\">/<logger level=\"INFO\" name=\"com.hp.maas.platform.services.mail\">/g" /opt/apache-tomcat/webapps/platform-webapp/WEB-INF/classes/sync/log-platform-base.xml
   

2. Apply the patch file on the control plane node. kubectl patch deploy itom-xruntime-platform -n <namespace> --patch-file platform-patch.yaml
3. (Optional) If you want to disable the logging file of the platform-offline pod, run this command: kubectl patch deploy itom-xruntime-platform-offline -n <namespace> --patch-file platform-patch.yaml
