Tools and utilities

Session data query utility

We provide a utility (ctxsdcutil) that you can use to query session data on each Linux VDA. To query the following data of all sessions or a specific session hosted on a VDA, run the/ opt / Citrix/VDA/bin/ctxsdcutil -q [-c]command. The[-c]argument means to query data every second.

• Input Session Bandwidth

• Output Session Bandwidth

• Output Session Line Speed

• Latency - Last Recorded

• Round Trip Time

• Output ThinWire Bandwidth

• Output Audio Bandwidth

• Output Printer Bandwidth

• Input Drive Bandwidth

• Output Drive Bandwidth

ThexdlcollectBash script

ThexdlcollectBash script used to collect logs is integrated into the Linux VDA software and located under/ opt / Citrix/VDA/bin．After you install the Linux VDA, you can run the bash/ opt / Citrix/VDA/bin/xdlcollect.shcommand to collect logs. After the log collection completes, a compressed log file is generated in the same folder as the script. ThexdlcollectBash script can ask you whether to upload the compressed log file to Citrix Insight Services (CIS). If you agree,xdlcollectreturns an upload_ID after the upload completes. The upload does not remove the compressed log file from your local machine. Other users can use the upload_ID to access the log file in CIS.

XDPing

The LinuxXDPingtool is a command-line application. It automates the process of checking for common configuration issues with a Linux VDA environment.

Install the LinuxXDPingtool

Running ctxsetup.sh does not installXDPing．To installXDPing, runsudo /opt/Citrix/VDA/bin/xdping．This command also creates aPython3virtual environment that is required forXDPing．If this command fails to create aPython3virtual environment, create it manually following the instructions atCreate aPython3virtual environment．

To address SSL connection errors that you might encounter when using the pip tool, consider adding the following trusted hosts to the /etc/pip.conf file:

[global]
trusted-host =
pypi.org
files.pythonhosted.org

Tasks that can be done withXDPing

XDPingcomes with the single executable namedxdpingthat is run from the command shell.

The following table describes the various tasks that can be done with the correspondingXDPingcommands:

Individual tests

The LinuxXDPingtool performs over 150 individual tests on the system, which are broadly categorized as follows:

• Check whether Linux VDA system requirements are met.
• Identify and display machine information including the Linux distributions.
• Check the Linux kernel compatibility.
• Check for any known Linux distribution issues that can impact the Linux VDA operation.
• Check the Security-Enhanced Linux (SELinux) mode and compatibility.
• Identify network interfaces and check network settings.
• Check storage partitioning and available disk space.
• Check machine host and domain name configuration.
• Check DNS configuration and perform lookup tests.
• Identify underlying hypervisors and check virtual machine configuration. Support for:
  • Citrix Hypervisor
  • Microsoft HyperV
  • VMware vSphere
• Check time settings and check whether network time synchronization is operational.
• Check whether the PostgreSQL service is properly configured and operational.
• Check whether SQLite is properly configured and operational.
• Check whether the firewall is enabled and the required ports are open.
• Check Kerberos configuration and perform authentication tests.
• Check the LDAP search environment for the group policy service engine.
• Check whether Active Directory integration is set up properly and the current machine is joined to the domain. Support for:
  • Samba Winbind
  • Dell Quest Authentication Services
  • Centrify DirectControl
  • SSSD
• Check the integrity of the Linux computer object in the Active Directory.
• Check Pluggable Authentication Module (PAM) configuration.
• Check the core dump pattern.
• Check whether packages required by the Linux VDA are installed.
• Identify the Linux VDA package and check the integrity of the installation.
• Check the integrity of the PostgreSQL registry database.
• Check whether the Linux VDA services are properly configured and operational.
• Check the integrity of the VDA and HDX configuration.
• Probe each configured Delivery Controller to test that the Broker Service is reachable, operational, and responsive.
• Check whether the machine is registered with the Delivery Controller farm.
• Check the state of each active or disconnected HDX session.
• Scan log files for the Linux VDA related errors and warnings.
• Check whether the version of Xorg is suitable.
• Check whether required dependencies are installed.

Scope of VDA registration status checks

The LinuxXDPingtool also provides an analysis module to help you check and analyze your VDA registration status. For a scope of registration status checks, see the following screen capture:

Backup and comparison of VDA data

Starting with the Linux VDA 2305, theXDPingtool introduces a VDA backup module. This module lets you back up the key data of a VDA at any time, such as the configuration, database, and binary permission data. You can back up the key data of a VDA when it is running properly. In case the VDA fails later, back up another copy of the data and compare the two copies of data to facilitate troubleshooting. The following table describes VDA data backup and comparison with the correspondingXDPingcommands:
