Integrating the appliance and Foglight

The Cartridge for FxM lets you consolidate key metrics gathered by Foglight Experience Monitor, and report them in Foglight with server-side and database metrics. This integration allows you to leverage the alerting and reporting capabilities of Foglight to evaluate the end-user experience by:

SLA enforcement

As a standalone appliance, Foglight Experience Monitor provides the ability to define and monitor various service-level metrics.

Foglight Experience Monitor provides the following metrics:

These service level metrics show the percentage of activity that satisfies the service level threshold that you have defined. For example, assume you are supporting an SAP-lead generation application, and you would like to ensure that 95% of users receive page download times of 2 seconds or better. You can define this application in Foglight Experience Monitor and assign it a Page End-to-End Time Threshold of 2000 milliseconds (or 2 seconds). Foglight Experience Monitor then reports on the percentage of page downloads that satisfy this threshold in the Application Page End-to-End Time Service Level metric for the application. These reports can be viewed in the appliance’s own Foglight Experience Monitor console.

After installing the Cartridge for FxM on the Foglight Management Server, many metrics can be viewed in the Foglight Console. In the figure below, the Foglight Console view shows the overall performance of the FMStocks service, including its ability to maintain its defined service levels; its response time service level affected by high client times, which makes the latter a potential an area for further investigation.

Foglight provides a set of rules that can generate alarms whenever a service level threshold is violated. Foglight allows you to modify rules and define separate sets of events depending on their severity levels (for example, normal, warning, critical or fatal). Typically, you would configure the rule to send an email when a fatal condition occurs. For more information on modifying rules, see the Foglight documentation.

Evaluation of the end user experience

A crucial objective of web-based application management is obtaining an accurate picture of the quality of service your users are experiencing. Ensuring users receive consistent and reliable service is critical for maximizing productivity and achieving end-user satisfaction. Lengthy page downloads or sluggish responsiveness can frustrate users, and lead to interruption or impairment of your organization’s business processes.

To satisfy these requirements, Foglight Experience Monitor provides a variety of metrics that report on the end-user experience from the perspective of web application components, web services, and the enterprise as a whole. With the Cartridge for FxM, you can monitor these metrics from the Foglight Console to evaluate the performance that your end users are receiving.

In Foglight 5, the Service Step Metrics view can be used to determine whether any specific pages that make up a service are incurring excessively larger processing or download times.

Once you detect a potential problem using these views and metrics, you can evaluate your entire application stack using Foglight agents that are reporting from the perspective of each tier: web, application, and database.

Monitoring the appliance health in Foglight 5

The Cartridge for FxM, with Foglight 5, allows you to verify that your appliance is not monitoring more traffic than it can handle. This problem can be manifested through appliance performance, such as CPU or memory utilization. An overloaded appliance can also become evident through failure with processing tasks, such as packet management or database record-writing. Other system-related issues include detected SOAP traffic errors, which is indicative of problems outside of the appliance itself.

Foglight provides you with a summary view of all appliance health metrics.
