4.4 Monitoring Access Gateway Alerts

The Access Gateway has been programmed to issue events to various types of systems (such as a
®
Novell Audit server or a Syslog server) so that the administrator can be informed when significant
changes occur that modify how the Access Gateway is performing. For information about auditing
and audit events, see
section describes how to use the following types of alerts:
Section 4.4.1, "Reviewing Java Alerts," on page 128
Section 4.4.2, "Configuring Access Gateway Alerts," on page 129

4.4.1 Reviewing Java Alerts

The Alerts page allows you to view information about current Java alerts and to clear them. An alert
is generated whenever the Access Gateway detects a condition that prevents it from performing
normal system services.

low, you might want to configure a pin list. For this and other caching
options, see Chapter 5, "Configuring the Content Settings," on
page 141.
