About Logging

The VCS provides a logging facility for troubleshooting and auditing purposes. The event log contains information about such things as calls, registrations, and messages sent and received.

The VCS logging facility allows you to:

specify the amount of information that is logged by changing the event log level,

specify an external server to which a copy of the log is written.

About Remote Logging

The event log is stored locally on the VCS. However, it is often convenient to collect copies of all event logs from various systems in a single location. A computer running

a BSD-style syslog server, as defined in

Logging Overview

About Event Log Levels

All events have an associated level in the range 1-3, with level 1 events considered the most important. The table below gives an overview of the levels assigned to different events.

See Events Logged at Level 1, Events Logged at Level 2 and Events Logged at Level 3 for complete tables of the events logged at each level.

Assigned Events

Level 1

High-level events such as registration requests and call attempts. Easily

(Protocol Verbose)

keepalives are also logged.

Setting the Event Log Level

You can control which events are logged by the VCS by setting the log level. All events with a level numerically equal to and lower than the specified logging level are recorded in the event log.

To set the log level:

System Configuration > Logging.

System Configuration > Logging.

You will be taken to the Logging page.
