VNA ACI Console Not Showing Health Scores in Performance Management

Issue/Introduction

VNA ACI Console Views are missing Health Scores

 

Cause

VNA and CAMM metrics for devices and their components are dropped after using the Stop and then Start Polling actions. 

Environment

Performance Management and VNA r3.6.8 and r3.7.3 or older releases

Resolution

Resolved via defect DE426041 in the r3.6.9 and r3.7.4 releases via code change in the Data Aggregator.

When the new code is in place, after a restart we need to force it to re-evaluate the SDN Polling Configurations on the devices that are missing them. This command will issue a re-evaluation on all devices that support the SDN protocol, and should make it so that we can again start processing ACI Health Scores. Issue the following POST via REST using the URL:

• http://<DA_HOST>:8581/action/polling-configuration/SDN/reevaluate

No body content is needed. Leave it empty.

The REST output will look similar to this:

• Successfully sent EvaluatePollingConfigProtocolAction to ( 8 ) devices for Polling Protocol: SDN - See DA Logs for details

The DA Logs will show the following (default paths specified):

Additional Information

Fixed Issues list for this issue will show the following:

• Symptom: VNA and CAMM metrics for devices and their components are dropped after using the Stop and then Start Polling actions. 
• Resolution: We will now correctly recreate the SDN and EMS Polling Configurations when the Start Polling action is sent to a device.
