Diagnostics Messages concerning system status and problems.
General Any message not in the categories above.
Remote Servers
(#1 and #2)
The IPv4 or IPv6 address of the remote server(s) where system logs are stored.
The system log is always saved to local EMG storage. It is retained through EMG unit
reboots for files up to Other Log Size (see below). Saving the system log to a server
that supports remote logging services (see RFC 3164) allows the administrator to save
the complete system log history.
Note: If the EMG is unable resolve the Remote Server hostnames or contact the
Remote Servers to send syslog messages, the syslog messages that cannot be sent to
a Remote Server may appear on the EMG console port.
RPM Log Size The maximum size in Kbytes that RPM logs can grow to before they are pruned. When
the file is pruned, it will be pruned to 50% of the RPM Log Size.
Other Log Size The maximum size in Kbytes that all logs other than the RPM logs can grow to before
they are pruned. When the file is pruned, it will be pruned to 50% of the Other Log Size.
Enable Log Select to save a history of all configuration changes in a circular log. Disabled by
default. The audit log is saved through EMG reboots.
Size The log has a default maximum size of 50 Kbytes (approximately 500 entries). You
can set the maximum size of the log from 1 to 500 Kbytes.
Include CLI
Commands
Select to cause the audit log to include the CLI commands that have been executed.
Disabled by default.
Include In System
Log
If enabled, the contents of the audit log are added to the system log (under the
General/Info category/level). Disabled by default.
Server IP address of your network’s Simple Mail Transfer Protocol (SMTP) relay server. If an
SMTP server is not specified, the EMG module will attempt to look up the MX record
for the domain in the destination email addresses of outgoing emails.
Sender The email address of the sender of outgoing emails. The strings "$host" and "$domain"
can be part of the email address - they will be substituted with the actual hostname and
domain. The default is donotreply@$host.$domain.
Enable Logins Enables or disables SSH logins to the EMG unit to allow users to access the CLI using
SSH. Enabled by default.
This setting does not control SSH access to individual device ports. (See
Device Ports
- Settings (on page 187)
for information on enabling SSH access to individual ports.)
Most system administrators enable SSH logins, which is the preferred method of
accessing the system.
Web SSH Enables or disables the ability to access the EMG command Iine interface or device
ports (connect direct) through the Web SSH window. Disabled by default.
Timeout If you enable SSH logins, you can cause an idle connection to disconnect after a
specified number of minutes. Select Yes and enter a value of from 1 to 30 minutes.
