Products

• CA Performance Management - Usage and Administration
• DX NetOps

Issue/Introduction

Data aggregator was migrated from an old server to the new server as the documentation in the wiki after which the Data aggregator and 
Data collector were showing correct status in NetOps Portal, however, after a restart of the Data aggregator the Data collector status is System health is failed.

Administration/Manage Data Source: all seems OK 
DataCollector: seems to be OK, STATUS green, Collecting Data. Graphs and dashboard seems to be OK. 
But: System health failed. 
If you click on it: Sync Normal, DA Normal, DC: Failed 

Environment

DX NetOps Performance Management all supported releases

Cause

NetOps Portal is polling the wrong Data aggregator to get the status of the Data collectors.



 

Resolution

Following are the steps to check if NetOps Portal is trying to poll the old Data Aggregator for Data collector status.

1. Login to following URL to enable debug on PC Side
   
   http://PC:8181/pc/center/admin/config/logs?listing=all
   
   
2. Change the Debug levels to Trace for the following 
   
   com.ca.im.portal.services.status.impl.DcStatusServiceProvider
om.ca.im.portal.services.status.impl.Utils
   
   
3. In the PCService.log you should see 
   
   ERROR | Status Poller-thread-1   | 2018-05-11 12:06:47,032 | com.ca.im.portal.services.status.impl.Utils
      | Failed in sending REST: http://oldDA:8581/rest/dcms

   If we are seeing the above. Please restart the NetOps Portal Services as per
   
   TechDocs : DX NetOps 23.3 : Restart NetOps Portal
   
   
4. After the Restart the System health should now show the correct status for Data collector.
