In NetOps Portal the Data Aggregator status is shown as unknown status. However all is working OK and the Data Aggregator status in the device context page state everything is green.
Release : 20.2, 21.2
Component : PERFORMANCE MANAGEMENT INTEGRATIONS
No reachability metrics are collected for the Data Aggregator
Currently working as designed and this does not impact the product functionality.
The UNKNOWN STATUS is the reachability status noted here:
When you mouse over the Unknown Status it tells you its Reachability status.
To get something other than Unknown Status, discover the Data Aggregator (DA) in the Default Domain using ICMP (no need for SNMP agent, just need ICMP support on DA device).
This way we should see UP when we are collecting ICMP from the DA item.
You will need a Data Collector in the Default Domain to discover the DA using ICMP.
