Log Screens
19.1 Overview
This chapter provides information on viewing and generating logs on your NWA.
Logs are files that contain recorded network activity over a set period. They are
used by administrators to monitor the health of the computer system(s) they are
managing. Logs enable administrators to effectively monitor events, errors,
progress, and so on. When network problems or system failures occur, the cause
or origin can be traced. Logs are also essential for auditing and keeping track of
changes made by users.
Figure 133 Accessing Logs in the Network
The figure above illustrates three ways to access logs. The user (U) can access
logs directly from the NWA (A) via the Web configurator. Logs can also be located
in an external log server (B) . An email server (C) can also send harvested logs to
the user’s email account.
19.1.1 What You Can Do in the Log Screens
• Use the View Log screen ( Section 19.2 on page 236 ) to display all logs or logs
for a certain category. You can view logs and alert messages in this page. Once
the log entries are all used, old logs will be deleted.
