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 like Fedora, 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 gathers information about the session, such as the applications in use and their consumption, system resource usage by the session, and session delivery times.

Supported versions

FlexxAgent 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 regularly validated.

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

Requirements

Before installing, updating all system packages is recommended. The necessary components will be installed, depending on the distribution.

Package dependencies for Fedora and Debian:

• dmidecode
• imvirt
• systemd

Limitations

Certain functionalities are unavailable for Linux, such as remote assistance, user microservices, flow execution, the collection of plug-and-play peripheral data, and proxy use.

The on-demand execution of microservices from Workspaces supports Bash as a scripting language.

Proxy Configuration

FlexxAgent for Linux supports communication through authenticated and unauthenticated proxies. The proxy information must be provided to Flexxible to include it in the configuration file mentioned in the next point.

Required data:

• For unauthenticated proxy, it will be necessary to provide URL and Port.
• For authenticated proxies, User and Password must be added to the above.

Download and installation

To install FlexxAgent, you must run the installation script using a preset configuration file.
