Issue/Introduction

Symptoms:

• How do I delete a Smarts device from M&R APG.
• Removed Smarts device from APG Management Database Metrics but the device still remains.
• After running through the following the standard M&R APG procedure for removing devices,Smarts devices still remain in APG.
• Cannot remove Smarts devices from M&R APG.
  
  

Environment

M&R- 7.x

Cause

This issue can have the following causes:

• Device has not been removed from Smarts: In addition to being removed from APG, the device must also be removed from Smarts.If a collector is still polling for device information, it will create the device even after being removed from APG Management Database Metrics. (Note: make sure the device was removed and not just unmanaged) 
• Import Properties task is not running: If import properties task does not complete successfully needs to be updated manually.

Resolution

• To successfully remove a Smarts device from M&R APG, you must do the following:

• • Remove the device from Smarts.
  • Remove the device from APG.
  • Update the flat table used by Tomcat to read APG data. 

• To remove a device from Smarts, run the following dmctl command against all Smarts domains:

  <SmartsBaseDir>./dmctl -s <APM Domain Name> invoke <class>::<instance> remove
  
  IMPORTANT! The device needs to be removed from all the Smarts domains.

• To remove the device from APG,do the following:

• • • Stop Default Collector Manager Service.

        ./manage-modules.sh service stop collector-manager Default

• • • In M&R GUI, Please go to the below location:

         APG administration > Modules > Management of Database Metrics

• Delete all metrics associated with device. To do this, search for the device name under Filter, select all, then delete.
• Start Default Collector Manager Service. In Windows, use cmd 'run as adminstrator mode' to run the following:
  

  ./manage-modules.sh service start collector-manager Default

• Manually run the import properties task 
  • If you want to see the change to take effect immediately, refresh the database flat table where tomcat reads the APG data from as follows:
  • Navigate to administration/centralized management/scheduled tasks/database.
  • Run :  import properties task
• Restart the Tomcat service:
  

   <APGbase>/bin/apg-tomcat-default restart

Additional Information

Note: If deleting metrics is not working, check import properties and make sure it is running successfully if it did not complete with a code 1, it is likely caused by crashed tables in the database.
