Problem:

No Self Monitoring Metric data is present in the CA Performance Manager System Health Dashboards

 

Configuration:

All CA Performance Manager releases

 

Description:

  • When displaying the out of the box System Health Dashboards receiving "No Data to Display"
  • When displaying customized System Health Dashboards receiving "No Data to Display"
  • When displaying Views to see Data Aggregator monitoring statistics receiving "No Data to Display"
  • When displaying Views to see Data Collector monitoring statistics receiving "No Data to Display"

 

Cause:

A common cause for this problem is the inadvertent deletion of the element in the Data Aggregator that represents the Data Aggregator.

 

Out of the Box Functionality:

  • When the Data Aggregator is first connected as a Data Source in a CA Peformance Manager system, it creates an element that represents itself.
  • This element is then tied to the "DA Health (Fast)", "DA Health (Normal)" and "DA Health (Slow)" Monitoring Profiles
  • Data is gathered (non-SNMP) from the systems to provide a view into system performance, resource usage and general health

 

When the Data Aggregator is inadvertent deleted, it is recreated by the system. When it is recreated it is assigned a new itemID in the database. We are then left with old data tied to a different itemID and a new Data Aggregator element no longer tied to the Monitoring Profiles.

 

Solution:

  1. NEVER delete the Data Aggregator element unless under the direction of CA Support or CA Sustaining Engineering representatives
  2. Once deleted unfortunately the solution is more intensive than simply reassigning Monitoring Profiles.

 

The full solution involves:

  • A REST based CURL command statement issued at the CLI of the Data Aggregator
  • VSQL statement commands on the Data Repository database
  • Data Aggregator restarts
