Products

• VMware Smart Assurance
• Network Observability

Issue/Introduction

• Live notification are not updated in MnR notification console while Smarts SAM shows several notifications.
• How can notification be synchronized between 2 products. 

Environment

Watch4Net/MnR - 7.x
Smarts - 10.1.x/24.3.10

Resolution

There are two options to synchronize SAM and the Notification cache: Stopping the SAM publisher to clear the Notification cache or stopping SAM to clear the Notification cache.

Stopping the SAM publisher to clear the Notification cache:

This method of clearing the Notification cache has less impact on the system as only SAM publisher is stopped.
Steps to implement:

• Stop the publisher as $SAM_Base/bin# dmctl -s <PRES-SAM_Domain> invoke SM_AMQPNotificationPublisher::SM-AMQPNotificationPublisher stop
• Clear the Notifications cache by typing these commands:
  • $SAM_Basedir/bin# sm_service stop smarts-elasticsearch
  • $SAM_Basedir/bin# sm_service stop smarts-rabbitmq
  • $SAM_Basedir/bin# sm_service stop smarts-tomcat
  • $SAM_Basedir# rm -rf local/repos/elasticsearch/nodes
  • $SAM_Basedir# rm -rf local/repos/rmq
  • $SAM_Basedir/bin# sm_service start smarts-elasticsearch
  • $SAM_Basedir/bin# sm_service start smarts-rabbitmq
  • $SAM_Basedir/bin# sm_service start smarts-tomcat
• Start the publisher: $SAM_Basedir/bin# dmctl -s <PRES-SAM_Domain> invoke SM_AMQPNotificationPublisher::SM-AMQPNotificationPublisher start

Stopping SAM to clear the Notification cache:

This method of clearing the Notification cache has a substantial impact on the system, as SAM domain needs to be stopped.
Steps to implement:

 

• Stop the SAM service as $SAM_Basedir/bin# sm_service stop ic-sam-pres
• Clear the Notifications cache by typing these commands:
  • $SAM_Basedir/bin# sm_service stop smarts-elasticsearch
  • $SAM_Basedir/bin# sm_service stop smarts-rabbitmq
  • $SAM_Basedir/bin# sm_service stop smarts-tomcat
  • $SAM_Basedir# rm -rf local/repos/elasticsearch/nodes
  • $SAM_Basedir# rm -rf local/repos/rmq
  • $SAM_Basedir/bin# sm_service start smarts-elasticsearch
  • $SAM_Basedir/bin# sm_service start smarts-rabbitmq
  • $SAM_Basedir/bin# sm_service start smarts-tomcat
• Start the SAM service as $SAM_Basedir/bin# sm_service start ic-sam-pres
