About Us

Welcome to Foglight

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 Development Kit

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

The Agent Manager Development Kit enables developers to create and manage custom Foglight agents.

These Release Notes cover the resolved issues, known issues, workarounds, and other important information about the 6.1.0 release of the Agent Manager Development Kit. Review all sections before starting the installation.

For information about issues resolved in the Agent Manager 6.1.0 release, see the Foglight Agent Manager 6.1.0 Release Notes.

The Agent harness shows topology property updates multiple times in message trees.


A verified submission status is never updated.


First verified submission is always lost.


The Agent harness reports the following error on debug level 1: java.lang.IndexOutOfBoundsException: Index: 10, Size: 10


A NullPointerException is thrown while an agent instance created by the AgentControlService is displayed under the Agent Type node in the tree.


Adding additional agent instances of the same type can cause a null pointer exception as a result of a call to the JTree.updateUI().


The ASP string editor in the Agent harness interprets "\n" as a new line.


Setting a label on an enum type property in the agent-definition.xml can cause a fatal error.


The Agent harness cannot write some configuration files to the state directory.


A core dump occurs while generating a heap dump from the Agent Harness menu on a Red Hat Enterprise Linux 6.x OS virtual machine.


Defect ID

Resolved Issue


An old agent running with a newer cartridge on the Management Server with an updated and incompatible ASP schema causes a NullPointerException in the agent's generated property wrappers.


Up-to-date check for topology wrappers is invalid.


TopologyValidator should ignore user-defined topology types that are only referenced from dynamic properties.


Core properties of a topology type that is a subtype of the TopologyObject type are being overridden.


Third party known issues

This release of the Foglight Agent Manager Development Kit does not include any third party known issues.


Upgrade and compatibility

The 6.1.x Foglight Agent Manager cartridge requires Foglight Management Server 5.9.2 or later. The cartridge is compatible with all previously released versions of the Agent Manager client application.

Agent Manager upgrades from a 5.5.4.x legacy release require an intermediary upgrade to 5.6.7 prior to upgrading to 5.8.5 or later. To complete this intermediary upgrade, install one or more of the Agent Manager 5.6.7 platform-specific cartridges (as required), and upgrade the legacy hosts to this release before deploying the 6.1.x Agent Manager cartridge or upgrading the Foglight Management Server to version 6.1. After all of the legacy hosts are running version 5.6.7, and the Foglight Management Server is upgraded to version 5.9.2 or later, you can start upgrading your hosts to version 6.1.x.


For more information about upgrading the Management Server and the Agent Manager, see the Foglight Upgrade Guide.
