Configuring Network Agent global settings

Use the Settings > Network Agent > Global page to define basic monitoring and logging behavior for all instances of Network Agent connected to the current Policy Server (the Policy Server whose IP address appears in the Web Security toolbar).

The Describe Your Network list identifies the IP addresses that are part of your network in IPv4 or IPv6 format. By default, Network Agent does not monitor the traffic sent between these IP addresses (internal network communications).

Network Agent does not use this list to determine which IP addresses to monitor for Internet requests. That behavior is configured separately for each Network Agent NIC (see Configuring Network Agent NIC settings). This list is used only to exclude internal traffic (like LAN and intranet connections) from monitoring.

An initial set of entries is provided by default. You can add more entries, or edit or delete existing entries.

The Internal Traffic to Monitor list includes any internal IPv4 or IPv6 addresses (encompassed by the “Describe Your Network” list) for which you do want Network Agent to monitor traffic. This might include internal web servers, for example, to help you to track internal connections.

Any request sent from anywhere in the network to the specified internal machines is monitored. By default, this list is blank.

Click Add to add an IPv4 or IPv6 address or range to the appropriate list. See Adding or editing IP addresses during Network Agent configuration for more information.
To edit an entry in the list, click the IP address or range. See Adding or editing IP addresses during Network Agent configuration for more information.
To remove an entry from the list, mark the check box next to an IP address or range, and then click Delete.

The Additional Settings options allow you to determine how often Network Agent calculates bandwidth usage, and whether and how often protocol traffic is logged:

Field	What to do
Bandwidth calculation interval	Enter a number between 1 and 300 to specify how frequently, in seconds, Network Agent should calculate bandwidth usage. An entry of 300, for example, indicates that Network Agent will calculate bandwidth every 5 minutes. The default is 10 seconds.
Log protocol traffic periodically	Mark this option to enable the Logging interval field.
Logging interval	Enter a number between 1 and 300 to specify how frequently, in minutes, Network Agent logs protocols. An entry of 60, for example, indicates that Network Agent will write to the log file every hour. The default is 1 minute.
