OneAgent

OneAgent released as BETA functionality for AppMon 2017 May. Please be aware that:

  • Not all features/sensors available in Classic Agent are already available in the OneAgent for AppMon
  • Features/Sensors known from Classic Agent can behave differently

To use OneAgent in AppMon 2017 May you need to install Classic Agents first, and then roll them out to the OneAgent. No additional configuration needed. Before you switch to OneAgent, double check your major requirements with the available feature set.

Warning

You must not use the OneAgent in your production environment. The aim of BETA is to test it in pre-production environment, and see how the new Agent affects your custom dashboards/configurations you use to monitor your production environment.
