Extending Your Monitoring Reach with Foglight Cartridges

Each Foglight® cartridge contains extensions for monitoring a specific environment, such as applications, operating systems, or database management systems. Cartridges are installed on the server. A cartridge can contain one or more agents that are used to collect data from monitored environments.

The Foglight Management Server includes a set of default cartridges that contain models, views and monitoring policies. In addition to these server-specific cartridges, there are other types of cartridges that are distributed separately from the server. They extend the server’s monitoring capabilities, allowing you to monitor specific types of environments, such as operating systems, processes, databases, applications, hosts, and others. These types of cartridges typically include agent packages, agent adapters, monitoring policies, and dashboards.

A cartridge monitoring policy contains settings that help Foglight analyze the data that the agents collect, such as rules, registry variables, schedules, and derived metrics. The items included in the monitoring policy are specific to each cartridge type. The dashboards included with a cartridge allow the information collected by the agents to be displayed in a unified view.

The Management Server includes the Cartridge Inventory dashboard, which contains controls for installing, enabling, disabling, and uninstalling cartridges, and for viewing information about the installed cartridges. To access this dashboard, from the navigation panel, click Dashboards > Administration > Cartridges > Cartridge Inventory.

Some cartridges include additional components, such as agent installers or additional configuration files. After cartridge installation, these components are available for download from the Foglight Management Server using the Components For Download dashboard. To access this dashboard, from the navigation panel, click Dashboards > Administration. On the Administration dashboard, click Component Download in the Cartridges column.

Configuring Foglight Agents for Host Monitoring

Foglight® agents collect data from monitored environments and send it to the Management Server. Each agent type can monitor a specific part of your environment, such as an operating system, application, or server. Foglight cartridges that you install on the server include one or more agent types. Foglight also includes internal agents that monitor Foglight components and services.

Foglight uses the Foglight Agent Manager to communicate with monitored hosts. A server installation includes an embedded Foglight Agent Manager. The embedded Agent Manager starts up and stops with the Foglight Management Server. This embedded instance can be used to monitor the host on which the Management Server is installed. To monitor additional hosts in your environment, most cartridges require an Agent Manager installation on each host computer.

After installing and enabling a cartridge, and downloading remaining cartridge components, deploy its agent package to each host running an Agent Manager that you want to monitor. After deployment, create an agent instance for each monitored host, edit the agent’s properties, and start its data collection. See the Installation and Setup Guide set for information on installing the Agent Manager on the hosts that you want to monitor.

There are two dashboards that allow you to deploy agent packages and create agent instances: Agent Status and Agent Managers. To access the Agent Managers dashboard, from the navigation panel, click Dashboards > Administration > Agents > Agent Managers.

To access the Agent Status dashboard, from the navigation panel, click Dashboards > Administration > Agents > Status.

Editing Agent Properties by Type

When an agent connects to the Foglight® Management Server, it is provided with a set of properties that it uses to configure its correct running state. Foglight stores agent properties on the Management Server.

You can edit the properties of agent types (global properties), or the properties of individual agent instances (private properties). Typically, after creating an agent instance, before its activation, you edit the agent properties. This causes the agent property values to become private. Agent instances with private properties are not affected by any subsequent changes made to its global properties. Changes to global properties are only carried over to new agent instances that are created after those changes.

Another classification of agent properties refers to their format, complexity, and shareability. Primary properties are typically text, number, or Boolean values. These types of values are easily specified and changed. Secondary or shared properties are in list form and contain multiple values organized into rows and columns. They can be easily cloned and modified to suit the needs of individual agent instances. The difference between primary and secondary (shared) properties is that secondary properties can be shared amongst multiple agent instances, meaning that a list can be associated with multiple agent instances of the same type. However, any changes made to a shared list affect all of those agents.

Any passwords that are defined in agent properties are encrypted. This feature is useful in situations when a database password is defined in agent properties, and there are multiple databases in your environment, for example, a Foglight database and a production database. Encrypting database passwords prevents unauthorized database administrators from accessing the database.

Agent properties can be edited using the Agent Properties dashboard. You can use it to edit the properties globally, for all instances of the same type, or only for a specific agent instance. To access this dashboard, from the navigation panel, click Dashboards > Administration > Agents > Agent Properties, or select an agent instance on the Agent Status dashboard and click Edit Properties.

Moving FglAM agents

The Agent Status dashboard allows you to move the FglAM agents within various FglAM hosts, if needed. To access the Agent Status dashboard, from the navigation panel, click Dashboards > Administration > Agents > Status. For the detailed information about the Agent Status dashboard, see Explore the Agent Status dashboard .

To move an FglAM agent:

NOTE: The agent movement function is only applicable for the FglAM agent which type is one of the following: FileLogMonitorAgent, UnixAgentPlus, WindowsEventLogMonitorAgent, MultiHostProcessMonitorAgent, PowerVMHMCAgent, UnixAgent, and WindowsAgent.
On the navigation panel, under Dashboards, click Administration > Agents > Status.
The Agent Status dashboard opens.
The Move selected agents to a different Agent Manager dialog box opens.
Use the group selector to select the target FglAM host from the Select Agent Manager drop-down list, and click Move.

Several Operating System (OS) and environment-specific issues, which include the following, may arise when moving an FglAM agent.

When moving an FglAM agent which ASP configurations include a value of “localhost”, it is strongly recommended that you change the corresponding ASP value to the name or IP address of the local host; otherwise the unexpected result may occur.
