Issue/Introduction

There is no event generated when the Threshold Violation was met.

Problem is specific to the Response Path Component items.

The affected items are found in the MySql netqosportal DB dst_components table but are not found in the em DB items table. Only items in the em items table are capable of raising Events.

Environment

All supported DX NetOps Performance Management releases

Cause

Unable to determine specific root cause. No log messages are found to indicate why the items are missing from the em DB items table.

Resolution

After multiple Event Manager Data Source Full Synchronization attempts the em DB items table counts for affected component items matched.

Once the items were present in the em DB items table the Events are now raising as expected.

Additional Information

This issue is specific to Response Path Jitter Component items. These items have an ItemSubTypeName in the DB of 'responsepathjitter'.

The following queries were used to determine the counts of items between databases.

1. Open a terminal on the NetOps PC Portal host.
2. Run the following commands.
   • For netqosportal dst_component table item counts:
     • /opt/CA/MySql/bin/mysql -u<USER> -p netqosportal -e "select count(*) from dst_component where ItemSubTypeName='responsepathjitter';"
   • For em items table item counts:
     • /opt/CA/MySql/bin/mysql -u<USER> -p em -e "select count(*) from items where ItemSubTypeName='responsepathjitter';"
