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.
