Sumo Logic Web Application

To check the version of the Collector: 

  1. Log in to Sumo Logic, then go to Manage > Collection.

Collector logs

To check the version of the Collector:

  2. View the collector.out.log file.
  3. You will find a Sumo Logic banner that contains the version number, as shown.
