Hardware System Requirements for Medium Deployment of Aternity on-premise (up to 20,000 devices)

Use this deployment for medium production environments of Aternity to support up to 20,000 monitored devices or virtual desktops, where up to 10% of them (around 2000) are virtual application sessions from up to 90 virtual application servers. It supports two Aternity users updating dashboards simultaneously, and assumes up to five monitored managed application per device which monitor the application's resource usage.

You must also install each server with the required operating system and other software. For details, see the system and software requirements for each server.

Sizing for a Medium Deployment

Contact Customer Services to help you estimate the size of your deployment, by calculating the following values:

Deployment Max # devices and VDIs # virtual sessions # virtual servers PRC WPM AR/min Non-WPM AR/min Discovery AR/min Aternity users

Medium Aternity deployment (see hardware requirements)










  • # devices and VDIs is the maximum number of monitored physical devices and virtual desktop VDIs (not their hypervisors) which report their performance to Aternity at the same time.

  • # virtual sessions is the maximum number of monitored virtual application sessions reporting their performance to Aternity at the same time.

    # virtual servers is the maximum number of virtual application servers (like Citrix XenApp) or RDP servers, which generate the monitored virtual sessions.

  • PRC is the average number of PRC monitors per device, averaged over 24 hours. By default, devices report PRC once an hour.

  • AR/min is the maximum number of activity response times reported per device per minute at peak times. There are two types:

  • Discovery AR/min The average number of applications which are actively in use simultaneously on a device per minute, which report discovery data (like usage time, wait time and UXI).

  • Aternity users The number of users who simultaneously update the display of a dashboard or perform a major administration feature.
