Linux

The Linux agent allows the inclusion of devices with this operating system in the service consoles, enabling support teams to have complete visibility of all devices in use within the organization. Linux support includes distributions such as Fedora, as well as Debian and its derivative Ubuntu. Both physical and virtual devices on VMware as a hypervisor and VDIs published with Citrix as a broker are supported.

FlexxAgent is composed of a process of the same name, which runs at the system level and obtains all device information: its consumption metrics, performance, and all information visible in the consoles related to the device. FlexxAgent-Session initiates an instance for each user session on the device. It collects session-related information, such as the applications used and their resource consumption, system resource usage by the session, and session delivery times.

Supported versions

Currently, FlexxAgent officially supports the following distributions and versions:

• Fedora 37 or later
• Debian/GNU Linux 11 (bullseye) or later
• Ubuntu 22.04, 24.04

More distributions are periodically validated.

To include any distribution in the supported distributions list, please contact Flexxible.

Requirements

Before installing, updating all system packages is recommended.

The necessary components will be installed, depending on the distribution. The packages are detailed below.

Package dependencies for Fedora and Debian:

• dmidecode
• imvirt
• systemd

Limitations

Certain functionalities are not available for Linux, such as remote assistance, user microservices, or executing flows, as well as collecting data from plug and play peripherals and proxy usage.

On-demand microservice execution from Workspaces supports Bash as the scripting language.
