Advanced configuration options

The appliance supports a variety of advanced configuration options that allow you to fine-tune how it monitors network traffic and generates reports. The following sections outline some of the advanced configuration options that are available.

For more information, see these topics:

Appliance management

Alarm Email Notification—you can configure groups of email addresses that will receive notifications when an alarm is triggered. For more information, see Email groups and Mail server.
User Account Management—you can create user accounts for each person you would like to have access to the appliance. Each account gives the user their own set of predefined reports and the ability to create additional customized reports. For more information, see User account management.
Security Profile—for organizations that required enhanced security for user account management, you can implement a security profile that separates user account management and access privileges between users of the web console and network or system administrators. For more information, see Increasing security for user account management and access privileges.

Data monitoring

Data Collection Policy—configure the appliance to apply a set of rules (or transformations) to the URLs that it is monitoring. This ensures that the Pages and Hits categories contain the level of granularity appropriate for your site. For more information, see Transforming monitored URLs.
Secure HTTP—if any of your monitored servers use SSL, and you did not provide the keys to the appliance during the Setup Wizard, this step can be performed using the web console.
For more information, see Configuring SSL keys.
Server Service Levels—the appliance provides the ability to define service level thresholds for the processing time consumed by each server. These thresholds can be modified to match the service levels desired by your organization. For more information, see Changing monitored servers service levels.
SOAP—the appliance can monitor SOAP activity that utilizes HTTP or HTTPS as transport protocols. A sequence of SOAP operations can be defined to form a transaction. For more information, see Monitoring SOAP applications and Configuring enterprise-wide service levels.
Services—a service, a sequence of web pages, can be defined and monitored by the appliance. For more information, see Managing services definitions.
User Sessions—appliance administrators can define how individual user sessions are identified by indicating end-user points of entry for web applications that are being monitored. For more information, see Identifying user sessions.
Application Components—web-based applications can be defined and monitored as a single entity by the appliance. For more information, see Managing application components.
Installing and configuring and Managing applications explain all of these configuration options in detail.

Foglight Experience Monitor and Ixia Net Tool Optimizers

The Ixia® Net Tool Optimizer (NTO) portfolio of smart taps provides aggregation, advanced filtering, load balancing, complex routing, and de-duplication of network traffic for monitoring devices like Foglight Experience Monitor.

Some NTO devices also provide a feature known as “hardware timestamping”, that can help improve the overall accuracy of metrics reported by Foglight Experience Monitor. When the hardware timestamping advanced feature is enabled, NTO devices append a trailer containing a timestamp to each packet.

The timestamping feature can use either a local time source or a Network Time Protocol (NTP) server. It is highly recommended that you use the NTP option with the same NTP server that is configured on your Foglight Experience Monitor system.

Make sure to enable the hardware timestamping for each port on the Ixia device that is feeding traffic to Foglight Experience Monitor.

Consult your local Ixia sales representative to determine which NTO device would be best for your environment.

For a description of how to enable the appliance to use hardware timestamps, see Configuring server options.
