Configure Logging

GigaVUE HC Series nodes provide comprehensive logging capabilities to keep track of system events. Logging is particularly useful for troubleshooting system issues, as well as maintaining an audit trail. You can specify what types of events are logged, view logged events by priority, date, or name, and upload log files to a remote host for troubleshooting.

Logged events are always written to the local log file (syslog.log). You can optionally specify an external syslog server as a destination for the GigaVUE HC Series node’s logging output. When an external syslog server is specified, the GigaVUE HC Series node will send logged events through UDP, TCP, or SSH to the specified destination.

To configure a syslog server as destination for logging in GigaVUE-FM, do the following:

1.

Using administrator user credentials, log in to GigaVUE-FM.

2.

On the left navigation pane, click , and then select Physical>Nodes. Select the required node or cluster.

3.

Select Settings > Global Settings > Logging.

4.

Click New Server. The Add Log Server page appears.

5.

Select the required hosts.

6.

Select the logging protocol: UDP or TCP

For UDP, do the following:

a.

Enter the external server’s IP address in the Server Address field.

b.

Port Number for UDP is 514, which is selected by default.

c.

Select the logging level from the Log Level list. For a description of the logging levels, refer to Table 1: Logging Levels.

For TCP, do the following:

a.

Enter the external server’s IP address in the Server Address field.

IPv6 addresses are supported; for example, 2001:db8:a0b:12f0::82. Also, hostnames are supported; for example, syslog.ipv6.

Note: IPv6 must be enabled before you can configure an IPv6 syslog server. To enable the IPv6, use the CLI command enable ipv6.

b.

Select the logging level from the Log Level list. For a description of the logging levels, refer to Table 1: Logging Levels.

c.

Enter the port number in the Port Number field.

For SSH, do the following:

a.

Use the Toggle option to enable SSH.

b.

Enter the user name for logging in to the SSH server in the Username field.
