Issue/Introduction

In CAPC web GUI the Data Collector status was unknown.  Nothing has changed with regards to the CA Performance Management setup. 

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

2020-01-06 19:57:01,196 | ERROR | roxyReg-thread-4 | ributeWriterRegistrationListener | bstractProxyRegistrationListener  108 | 184 - com.ca.im.item-repository.impl - 3.7.0.RELEASE-355 |  | AttributeWriterRegistrationRequest failed for {SourceRegistrationDTO [facetType={http://im.ca.com/certifications/snmp}CiscoRttMonStatsMib, facetPropertyName=null, facetPropertyValue=null, attribute=null]}

The DC processes are up and have not terminated. 

Cause

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

Environment

Release : 3.7

Component : IM Reporting / Admin / Configuration

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.
