Performance reduction for a specific host due to disabling PubSub over MessageBus

Updated Sept 14, 2016

Overview

A message displays in the notification center that there is a minor performance reduction due to disabling Pub/Sub over MessageBus for specific hosts. If you check your SolarWinds logs on the host computer, the logs have multiple RabbitMQ errors.

 

Environment

Any 32-bit OS or FIPS environment running on Orion Platform 2016.3 or later, which includes the following products:

  • NPM 12.0.1 or later
  • SAM 6.3 or later
  • NCM 7.5.1 or later
  • NTA 4.2.1 or later
  • Patch Manager 2.1.3 or later

 

Cause 

RabbitMQ may not be installed or running on the primary Orion server. Port 5671 is not open between the scalability engine and the primary Orion server.

Resolution

You have two options to resolve this issue: 

  • Ensure the primary Orion server has RabbitMQ running.
  • Disable RabbitMQ messaging.
    • Run configuration wizard, with services checkbox enabled, on the affected scalability engines.
    • Dismiss any RabbitMQ warnings from the notification panel.
