About Dell

Welcome to Foglight

Welcome to Foglight

Dell's Foglight™ solution simplifies application performance monitoring and reduces the skills and effort required to manage applications, the user experience, and the supporting infrastructure.
Unlike other solutions, Foglight uses a single code base, and has a model-driven design that couples fast deployment and accelerated time-to-value. It offers the modular flexibility required to deliver a range of capabilities and sophistication to meet the needs of any organization—from those still focused on technology-centric monitoring to those that have completed the transition to application-centric or transactional monitoring.

Foglight performs equally well in physical, virtual, and mixed infrastructure environments, providing visibility into issues affecting the application and end-user experience. Intuitive workflows help you quickly move from the symptom to the root cause in the application, database, infrastructure, or network to resolve issues, reducing mean time to resolution. Predefined and drag-and-drop dashboards provide insight that is tailored to each stakeholder. By offering comprehensive visibility into your monitored environment, Foglight helps ensure that cross-functional teams collaborate on and prioritize issues that matter most to the business.

Foglight Agent Manager

Foglight agents require the Foglight Agent Manager (FglAM) to manage their life-cycles and centralize communications with the Foglight Management Server.

For information about the supported platforms for the Agent Manager, see the System Requirements and Platform Support Guide.

These Release Notes cover the resolved issues, known issues, workarounds, and other important information about the 5.8.1 release of the Agent Manager. Review all sections before starting the installation.

This release includes the following new features:

• Support for High Availability mode. The Agent Manager supports HA (high availability) mode. In this mode multiple Agent Managers can work together, allowing agent instances to fail over to another Agent Manager, if needed. (FAM-4213)
• Reverse polling. The Agent Manager now accepts connections from the Management Server and enables reverse data polling. This is useful in situations when the Agent Manager cannot connect to the Management Server due to its location. For example, when the Agent Manager is located in the cloud and the Management Server runs on premises, the Agent Manager has no means to connect to the Management Server and pass on the collected data. Another example is when the Agent Manager resides in a demilitarized zone (DMZ), exposed to untrusted networks, and the Management Server is behind a firewall. For more information about this feature, see the Agent Manager Guide. (FAM-4135)
• Secure connections to the Management Server. Due to a sensitive nature of monitored data, externally installed Foglight Agent Managers are now required to use HTTPS connections for communication with the Management Server. You can override this behavior, if needed, as described in FAM-5596. For complete information, see the Agent Manager Guide.
• Low memory detection. If the memory usage exceeds 95%, the Agent Manager logs a message every 30 seconds. (FAM-3970)
• Support bundle enhancements. Agent Manager performance metrics are added to the support bundle in this release. (FAM-3660)
• Certificate management improvements. SSL certificates can be added using the installation and configuration interface, or the command line, instead of the keytool executable. (FAM-3582)

Release Notes for the Agent Manager Development Kit are now provided in a separate document: Foglight Agent Manager 5.8.1 Development Kit Release Notes.
