Before installing Foglight for Active Directory, ensure your system meets the following minimum hardware and software requirements:
Note: Foglight for Active Directory only supports to monitor an Active Directory installed on an Azure VM. That is if a domain controller (DC) is an Azure VM instead of on-prem VM, then we can monitor it. However, AD cartridge does not support monitoring Azure AD itself.

Monitored Domain Controllers must be Windows Server® 2008 or newer. Note: If you are using Windows Server 2008 R2, refer to the prerequisites described in the Prerequisites and Troubleshooting sections. Small Business Systems (SBS) versions have not been tested. |
The following prerequisite conditions must be in place in order to successfully initialize an Active Directory agent. Failure to meet these prerequisites may result in missing metrics in Foglight for Active Directory dashboards.
Note: The Remote Access Diagnostics utility, provided with this product, checks the connectivity between the Foglight Agent Manager (FglAM) and Active Directory and Exchange servers that are being monitored. It also tests for the prerequisite conditions that must be met in order to initialize an Active Directory agent. For more information on running the Remote Access Diagnostics utility, see the Remote Access Diagnostics User Guide.
Note: Make sure to give minimum required privilege to your Active Directory® or Certificate Authority agent; otherwise this agent can not start data collection.
An Active Directory account with Administrator permissions (domain or built-in administrators) must be specified in agent properties. This is the account used to run remote scripts. Foglight for Active Directory uses the userPrincipalName in the agent properties, so the sAMAccountName and the account CN must be identical. Also, they must not contain spaces, or LDAP authentication errors may occur.
To run remote scripts, a Certificate Authority agent requires an account with relevant privileges:
Server objects do not appear until at least one piece of data has been collected and recorded. If communication fails completely, you will not see objects.
Configuration steps:
Since Foglight for Active Directory uses an agent-less design, remote execution of scripts must be enabled on all domain controllers. If communication fails completely, you will not see server objects. If partial data is collected, the server object will appear in the UI and the metrics with values will be displayed.
Distributed COM (DCOM) must be enabled on all Domain Controllers (Active Directory Servers) or all Certificate Authority Servers.
To enable Distributed COM (DCOM):
For details about this topic, refer to the "Configuring Windows Remote Management (WinRM)" section in the Foglight Agent Manager Guide.
The Remote Registry service must be running to allow agents remote access to the registry.
The account specified in the agent properties must have Full Control permissions on the registry keys.
Refer to Permissions on registry keys to configure DCOM command shell connection in Foglight Agent Manager Guide for detailed information.
The Extensible Storage Engine (ESE) is the database engine used by Active Directory. Foglight for Active Directory collects metrics and will fire alarms on ESE performance. It is recommended to verify that the Win32_PerfRawData_ESENT_Database WMI class is registered on each monitored domain controller by confirming the 'Database' Performance Object within Performance Monitor (Perfmon) exists. If this class is not registered, ESE queries will fail with 0x80041010 errors.
To check and register the ESENT WMI Class:
This procedure sets registry keys and refreshes the WMI database so it is aware of the change.
The Kerberos configuration file specifies the KDC from which tickets are obtained. Operating systems sometimes have their own Kerberos configuration files. If present, the Agent Manager uses them by default. They can be found in the following locations:
If none of these files are found, the Agent Manager attempts to create its own kerberos configuration file, based on the detected settings. The detection can only be done on Windows, so on Unix, the file is not generated. On Unix platforms, you need to create your own Kerberos configuration files to establish WinRM connections using Negotiate authentication.
The krb5.ini or krb5.conf file should contain the realm info and hostname of the KDC for this realm. For example:
[libdefaults]
default_realm = <REALM_NAME_IN_CAPS>
[realms]
<REALM_NAME_IN_CAPS> = {
kdc = <fully_qualified_kdc_name>
}
[domain_realm]
.<domain_in_lower_case> = <REALM_NAME_IN_CAPS>
