This section provides information about problems that you might encounter while monitoring your environment with Foglight for Active Directory, and describes the solutions available to troubleshoot these problems.
Symptom: In some circumstances, DCs on Windows Server 2012/2012 R2 systems may experience high CPU usage when monitored by the Active Directory agent. This issue only appears when using WinRM connections. Using WMI/DCOM connections prevents this issue.
Resolution:
If this issue is encountered, contact Support for assistance.
To troubleshoot this issue directly, use the Windows Task Manager to look for an increasing number of active conhost.exe or svchost.exe processes. If this problem is observed, the problem can be confirmed by adding the optional "Command Line" column to Task Manager (View > Select Columns > [ x ] Command Line). You should then see WinRM commands associated with the conhost.exe or svchost.exe instances.
If many of these processes are observed, increase the WinRM message envelope size from the default size of 500, as follows:
winrm set winrm/config @{MaxEnvelopeSizekb="1000"}
Microsoft® offers a workaround for this issue in the "Svchost.exe uses excessive CPU resources on a single-core Windows Server 2012 domain controller" article (KB 3118385).
The following procedure is a best practice that is recommended for optimal performance.
Do NOT allow the Microsoft® automatic update feature to force an update of the server hosting the Foglight Management Server. This automatic update feature does not allow enough time for the Foglight Management Server to shutdown gracefully, which may leave your agents in a broken state.
Symptom: Cartridge agents will appear to be deactivated on the Agent Status dashboard.
Resolution: Using the Agent Status dashboard, select the deactivated agent and select the Activate button. If you cannot activate the selected agent, delete and reinstall the agent.
Symptoms:
When upgrading to version 6.3.0, you encounter an error message similar to the following message (actual values may vary):
Error deploying package … Cause: The addition of 2097152kb to the negotiated JVM Max heap size would adjust to 2359296kb, which would exceed the total available physical memory of 1780736kb. Rejecting memory request.
Resolution:
This message indicates that the Agent Manager does not have sufficient heap memory to allocate to the requesting Foglight for Active Directory agent package. It is not possible to directly increase the amount of heap memory available to the Agent Manager, as it uses as much memory as the monitoring host can provide to it before issuing this message. The amount of memory available to be allocated to the Agent Manager must be increased, for example by adding more physical memory to the host. If the monitoring host is a virtual machine, more memory may be allocated to the VM.
If this is not possible, consider moving some agents, or the Agent Manager and all agents, to another monitoring host which has more memory capacity.

Foglight includes a licensing capability that restricts access to those features that are defined in the license. Any Management Server installation requires a license that grants access to server-specific parts of the browser interface and the features associated with them. Foglight cartridges are also license-protected. While some cartridges are covered by the base Foglight license (such as Foglight Agent Manager cartridges and the Cartridge for Infrastructure), others may require an additional license. Foglight for Active Directory is covered by the Foglight Evolve Monitor, Operate, and Flex license.
To activate a trial or a purchased commercial license:
The Foglight for Active Directory release package contains the following:
Foglight for Active Directory can be installed as a stand-alone cartridge on a Foglight platform. In this configuration, all Active Directory® metrics are collected as well as basic host metrics from both physical and virtual domain controllers. Before installing the cartridge, ensure that your Foglight Management Server is properly installed and configured. For information on how to install and configure the Foglight Management Server, refer to the Foglight Installation and Setup Guide set.
Foglight for Active Directory can also be installed on a Foglight Evolve or Foglight for Virtualization, Enterprise Edition platform. In this configuration, it is used to gain in-depth insight into the health of the virtual machine, the virtual host, and the virtual environment as a whole. Before installing the cartridge, ensure that Foglight Evolve or Foglight for Virtualization, Enterprise Edition is properly installed and configured. For information on how to install and configure Foglight Evolve or Foglight for Virtualization, Enterprise Edition, refer to the Foglight Installation and Setup Guide set.
You can use one Foglight Agent Manager (FglAM) with the following settings to support 25 to 30 agent instances: 6 GB memory and 2 CPU.
It is recommended that you perform the following steps before you begin the installation procedure:
Foglight for Active Directory is distributed as a .car file: Active-Directory-5_8_3.car. Use the Administration > Cartridges > Cartridge Inventory dashboard to install the cartridge. For full installation instructions, refer to the topic "Installing Foglight Cartridges" in the Foglight Administration and Configuration Help.
In order for Active Directory® data to appear on the Foglight browser interface, once the cartridge has been successfully installed, you need to deploy the agent package, configure the agent properties, create and activate agents, and start the data collection. For detailed information about these procedures, refer to Foglight for Active Directory User and Reference Guide.
