36 Chapter 2 Status and logging
NN46110-602
Most events are sent to the event log first. Significant events from the event log are
sent to the system log. (Not all data that the system log saves comes from the
event log.) From the system log, the VPN Router filters security entries for the
security log and configuration entries for the configuration log. You can use the
different log options to write specific event levels to the log files and view them,
including:
• Normal
• Urgent
• Detailed
• All
Sessions
You can monitor which users are tunneled into the VPN Router, when they logged
in, and the number of bytes and packets they transmitted or received. Additionally,
you can see selected session details, and you can log off users.
Once a session is connected, detailed information about the connection is
available from the Status
> Sessions window. This window lists all connected
sessions, including administrative sessions. As well as statistics, this information
contains what encryption was negotiated and the SOIs of the security associations.
Click the appropriate buttons beside each session to either log out of the session or
view detailed information about it.
Reports
Use the Status > Reports window to view system and performance data in text or
graphical format. You generate reports in an on-screen tabular format, and you can
import the reports into a spreadsheet or database through the comma-delimited
format.
At midnight (12:00 a.m.), the data collection task performs summary calculations
and rewrites history files, along with other management and cleanup functions. To
perform this task, leave the VPN Router running overnight. The VPN Router must
be running at midnight to generate a historical graph for the day.
