Diagnostics tools

The Diagnostics menu contains links to pages with run-time information and functions that may be useful for troubleshooting.


Note


The diagnostic options in the OSD are a subset of those available through the Administrative Web Interface.


Event log message display

The Event Log page lets you view and clear event log messages from the client. The web interface lets you change the log filter setting on the device, which controls which messages are put in the log. When you set the filter to “terse,” the device logs terse messages.

The Event Log page also lets you enable and define syslog as a way of collecting and reporting your events that meets the IETF standard for logging program messages.

Syslog Features

  • Allows separation of the software that generates messages from the system that stores them and the software that reports and analyzes them.
  • Provides devices that would otherwise be unable to communicate a way to notify administrators of problems or performance.
  • Can be used for computer system management and security auditing as well as generalized informational, analysis, and debugging messages.
  • Is supported by a wide variety of devices and receivers across multiple platforms.
  • Can be used to integrate log data from many different types of systems into a central repository.
  • Has messages that:
    • refer to a facility (auth, authpriv, daemon, cron, ftp, lpr, kern, mail, news, syslog, user, uucp, local0, ... , local7 ) .
    • are assigned a priority/level (Emergency, Alert, Critical, Error, Warning, Notice, Info or Debug) by the sender of the message.
  • Lets you direct messages to various local devices (console), files (/var/log/) or remote syslog daemons.

Note


Take care when you update the configuration as omitting or misdirecting message facilities or levels can cause important messages to be ignored by syslog or overlooked by the administrator.

Table 1 Event Log Parameters
Parameter Description
Event log Messages

View: Click to open a browser page that displays the event log messages (with timestamp information) stored on the device. Press F5 to refresh the browser page log information.

Clear: Click to delete all event log messages stored on the device.

Event Log Filter Mode

Click the pull-down menu to filter the event logs. Options include:

  • Verbose (this is the default setting)
  • Terse
Enable Syslog

Enable the syslog standard for your event logs. If syslog is enabled, you must configure the remaining fields (if disabled, they are non-editable).

Identify Syslog Host By

Choose if the syslog host is identified by IP address or by FQDN. If you enter an invalid IP address or DNS name, a message appears to prompt you to correct it. The parameter depends on which method you choose:

  • IP Address: The IP address for the syslog host
  • FQDN: The DNS name of the syslog host
Syslog Host IP Address / Syslog Host DNS Name

If you set the Identify Syslog Host By field to:

  • IP Address: Enter the IP address for the syslog host
  • FQDN: Enter the DNS name for the syslog host
Syslog Host Port Lets you configure the syslog port number.
Syslog Facility

The facility is a number attached to every syslog message used to categorize the source of the syslog messages. The facility is part of the standard syslog header and can be interpreted by all syslog servers.

Enter a facility to suit your logging needs. For example, you could configure:

  • zero clients to use facility 19
  • Cisco routers to use facility 20
  • VMware ESX hosts to use facility 21
Note   

The default facility is set to “19 – local use 3”. Cisco routers default to “23 – local use 7”.

Enhanced logging mode

If you require enhanced logging details in the event log to help troubleshoot a problem with a zero client, select an enhanced logging category, and then click Apply > Continue. (To return to normal logging mode, click Disable, and then Apply > Continue.)

Note   

Enhanced logging may be enabled for only one category at a time. Enhanced logging mode messages can be located in the event log by their Level 3 (LVL:3) designation, which indicates a debug-level message.

Enhanced logging mode categories:

  • Audio: Provides enhanced audio-related details, such as audio compression levels and audio bandwidth. Enable this mode if you are experiencing any problems with audio quality.
  • Management Console: Provides debug-level details for the connection state between the device and the MC. Enable this mode if you are having trouble connecting to or managing the device using the MC.
  • Networking: Provides socket-level details for a device's network connections. Enable this mode for network-related issues, for example, if the device cannot connect to a peer or broker, or if it cannot get an IP address from a DHCP server.
  • OneSign: Provides enhanced logging for connections using Imprivata's OneSign Single Sign-On proximity cards. Enable this mode to see debug-level messages between a device and a OneSign authentication server.
  • Session Negotiation: Provides pre-session messaging details, such as the full feature set advertised by each device. Enable this mode for low-level session negotiation details.
  • SmartCard: Provides debug-level messages for smart cards. Enable this mode if you experience trouble tapping or logging in using a smart card.
  • System: Provides heartbeat details about the device, such as ambient temperature. Enable this mode for system-level problems.
  • USB: Provides details of the traffic between the device and any connected USB devices. Enable this mode if you are experiencing problems with a connected USB device.
  • Video: Displays enhanced image-related logging information. Enable this mode for image problems, monitor problems, or display topology issues.

Audio test tone

The Audio page allows you to generate an audio test tone from the client.


Note


Cisco recommends that you do not wear the headphones during the audio test. Instead, hold them approximately two feet away from your ears because the volume level is loud and cannot be adjusted.


To generate an audio test tone, click Start to start the test tone. Click Stop to stop the test.


Note


The Audio page functionality is only available on a client when the client is not in a PCoIP session.
