Issue/Introduction

In NetOps Portal GUI the Data Collector status was unknown.  Nothing has changed with regards to the NetOps Performance Management setup. 

When reviewing the file karaf.log from the Data Collector, it has the following entries around the time we started the DC:

The DC processes are up and have not terminated. 

Environment

DX NetOps Performance Management 

Cause

The root cause in this scenario was down to not having the correct ports enabled for communication between Data Aggregator and the Data Collector.  

Resolution

Not all the correct ports were enabled (using unsecured).  Once the correct ports were opened, almost immediately the status changed to collecting data (green).   Regarding ports the following must be enabled: 

TCP 8581	Enables the simplified upgrade for Data Collectors. For more information, see Upgrade the Data Collectors.
TCP/AMQ 61616	Enables only ActiveMQ traffic between the Data Collector and Data Aggregator.
TCP/AMQ 61618	Enables poll response delivery traffic between the Data Collector and Data Aggregator.
TCP/AMQ 61620	Enables distributed IREP traffic between the Data Collector and Data Aggregator.
TCP/AMQ 61622	Enables large data transfers between the data collector and the data aggregator
