VQE System Messages


This appendix provides information on the Cisco VQE system messages. The VQE software writes these messages to these locations:

VQE-S system messages are written to the /var/log/vqe/vqe.log file.

VQE Client Channel Configuration Delivery Server (VCDS) system messages are also written to the /var/log/vqe/vqe.log file.

Not all system messages indicate problems with VQE. Some messages are purely informational, while others may help diagnose problems with communications links or the operating system (for example, file permission problems). Only critical messages are displayed on the CDE110 console.

For information on VQE-S AMT and VCPT logging output, see the "VQE-S AMT and VCPT Logging and Log Files" section on page 5-2.

System Message Structure

System messages are structured as follows:

FACILITY-SEVERITY-MNEMONIC: Message-text

FACILITY code

The facility code consists of two or more uppercase letters that indicate the facility to which the message refers. Table C-1 lists the VQE facility codes.

Table C-1 VQE Facility Codes  

Code
VQE Facility

STUN_SERVER

STUN Server (VQE-S)

VQES_CP

VQE-S Control Plane

VQES_DP_CLIENT

VQE-S Data Plane Client

VQES_DP

VQE-S Data Plane

VQES_MLB_Client

VQE-S Multicast Load Balancer Client

VQES_MLB

VQE-S Multicast Load Balancer

VQES_PM

VQE-S Process Monitor

VQE_CFGTOOL

VQE Configuration Tool (vqe_cfgtool command)

VQE_CFG

VQE channel configuration

VQE_HASH

VQE hash table

VQE_RPC

VQE-S Remote Procedure Calls

VQE_RTP

VQE Real-Time Transport Protocol
(Many of these messages are related to RTP Control Protocol (RTCP)).

VQE_RTSP

VQE Real Time Streaming Protocol (VCDS related)


SEVERITY level

The severity level is a single-digit code from 0 to 7 that reflects the severity of the condition. The lower the number, the more serious the situation. Table C-2 lists the message severity levels. Messages of severity 7 (Debugging) are not described in this appendix.

Table C-2 Message Severity Levels

Severity Level
Name
Description

0

Emergency

System is unusable.

1

Alert

Immediate action is required.

2

Critical

Critical condition

3

Error

Error condition

4

Warning

Warning condition

5

Notification

Normal but significant condition

6

Informational

Information message only

7

Debugging

Message that appear during debugging only


MNEMONIC code

The combination of the facility code and the mnemonic code uniquely identifies the error message.

Message-text

Message-text is a text string that describes the condition. The text string sometimes contains detailed information about the event, including port numbers and network addresses. Because variable fields change from message to message, they are represented here by short strings enclosed in square brackets ([ ]). A decimal number, for example, is represented as [dec]. Table C-3 lists the variable fields in messages.

Table C-3 Representations of Variable Fields in Messages

Representation
Type of Information

[chars] or [char]

Character string

[dec]

Decimal

[hex]

Hexadecimal integer

[int]

Integer

[num]

Number


System Message Example

The following is an example of a VQE system message:

VQES_CP-3-CP_CHANNEL_DELETE_ERR: Failed to delete a channel due to [chars] 

VQES_CP is the facility code.

3 is the severity level.

CP_CHANNEL_DELETE_ERR is the mnemonic code.

"Failed to delete a channel due to [chars]" is the message text.

Basic Recovery Procedures

In the Recommended Actions of the system messages, certain recovery procedures that VQE users should perform are referred to numerous times. Table C-4 provides references to where you can find more information on these recovery procedures.

Table C-4 Recovery Procedures in Recommended Actions

Recovery Procedure in Recommended Action
Notes and Where to Find Information

Reboot the VQE-S server.

Restarting the System and Verifying System and VQE-S Status, page D-21

Restart the VQE-S application.

Stopping, Starting, and Restarting VQE-S, page 5-16

Restart the VQE-S channels.

In VCPT, use the Force Update button to send the channel information to the VQE Server. See the "Force Update Button" section on page 3-5.

Modify the channel configuration and resend it to the VQE Servers and/or VCDS servers.

Chapter 3, "Using the VQE Channel Provisioning Tool"

Modify vcdb.conf and apply the configuration.

For VQE configuration (vcdb.conf) information, see Chapter 6, "Configuring VQE Server and VQE Tools."

For information on applying a VQE configuration with the -apply option to vqe_cfgtool, see the "Using the VQE Configuration Tool Command-Line Options" section on page 6-16.

Issue the vqereport command to gather data that may help identify the nature of the error.

"Using the vqereport Command" section on page 5-15


VQE System Messages Reference Information

Starting with VQE Release 3.0, reference information for the VQE system messages is listed in HTML format in a file that is available for each release in the VQE software download area on Cisco.com. The system messages file is located with the associated software release.

For each system message, the HTML file contains the message text, an explanation of the message, and a recommended action describing what (if anything) you need to do. For example:

Error Message    STUN_SERVER-2-SS_INIT_FAILURE_CRIT: STUN Server initialization failed 
due to [chars] 

Explanation    A software error has occurred during the initialization of the STUN Server process and the process will not start.

Recommended Action    Restart the VQE-S application. If this message recurs, copy the error message exactly as it appears in the VQE-S system log. Contact your Cisco technical support representative, and provide the representative with the gathered information.


Note The Recommended Action frequently involves a recovery procedure (for example, "Restart the VQE-S application.") that is described in the "Basic Recovery Procedures" section.
