Resolution:

A few solutions are possible.

  1. Resolve the internal network deficiencies leading to failed short host name communications
  2. Edit the Data Aggregator Data Source in the CA Performance Manager UI from using short host name to using FQDN.
  3. Edit the Data Aggregator Data Source in the CA Performance Manager UI from using short host name to using its IP address.
