Supported operating systems

See Overview of Azure Monitor agents for a list of Windows versions supported by the Log Analytics agent.

SHA-2 Code Signing Support Requirement

The Windows agent will begin to exclusively use SHA-2 signing on August 17, 2020. This change will impact customers using the Log Analytics agent on a legacy OS as part of any Azure service (Azure Monitor, Azure Automation, Azure Update Management, Azure Change Tracking, Microsoft Defender for Cloud, Microsoft Sentinel, Windows Defender ATP). The change does not require any customer action unless you are running the agent on a legacy OS version (Windows 7, Windows Server 2008 R2 and Windows Server 2008). Customers running on a legacy OS version are required to take the following actions on their machines before August 17, 2020 or their agents will stop sending data to their Log Analytics workspaces:

  1. Install the latest Service Pack for your OS. The required service pack versions are:

    • Windows 7 SP1
    • Windows Server 2008 SP2
    • Windows Server 2008 R2 SP1
  2. Install the SHA-2 signing Windows updates for your OS as described in 2019 SHA-2 Code Signing Support requirement for Windows and WSUS

  3. Update to the latest version of the Windows agent (version 10.20.18029).

  4. Recommended to configure the agent to use TLS 1.2.

Network requirements

Update

See Log Analytics agent overview for the network requirements for the Windows agent.

Configure Agent to use TLS 1.2

TLS 1.2 protocol ensure the security of data in transit for communication between the Windows agent and the Log Analytics service. If you're installing on an operating system without TLS 1.2 enabled by default, then you should configure TLS 1.2 using the steps below.

  1. Locate the following registry subkey: HKEY_LOCAL_MACHINESystemCurrentControlSetControlSecurityProvidersSCHANNELProtocols

  2. Create a subkey under Protocols for TLS 1.2 HKLMSystemCurrentControlSetControlSecurityProvidersSCHANNELProtocolsTLS 1.2

  3. Create a Client subkey under the TLS 1.2 protocol version subkey you created earlier. For example, HKLMSystemCurrentControlSetControlSecurityProvidersSCHANNELProtocolsTLS 1.2Client.

  4. Create the following DWORD values under HKLMSystemCurrentControlSetControlSecurityProvidersSCHANNELProtocolsTLS 1.2Client:

    • Enabled [Value = 1]
    • DisabledByDefault [Value = 0]

Windows 10 Update Agent X64

Configure .NET Framework 4.6 or later to support secure cryptography, as by default it is disabled. The strong cryptography uses more secure network protocols like TLS 1.2, and blocks protocols that are not secure.

  1. Locate the following registry subkey: HKEY_LOCAL_MACHINESOFTWAREMicrosoft.NETFrameworkv4.0.30319.
  2. Create the DWORD value SchUseStrongCrypto under this subkey with a value of 1.
  3. Locate the following registry subkey: HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoft.NETFrameworkv4.0.30319.

  7. On the Azure Log Analytics page, perform the following:
    1. Paste the Workspace ID and Workspace Key (Primary Key) that you copied earlier. If the computer should report to a Log Analytics workspace in Azure Government cloud, select Azure US Government from the Azure Cloud drop-down list.
    2. If the computer needs to communicate through a proxy server to the Log Analytics service, click Advanced and provide the URL and port number of the proxy server. If your proxy server requires authentication, type the username and password to authenticate with the proxy server and then click Next.
  8. Click Next once you have completed providing the necessary configuration settings.
  9. On the Ready to Install page, review your choices and then click Install.
  10. On the Configuration completed successfully page, click Finish.

When complete, the Microsoft Monitoring Agent appears in Control Panel. To confirm it is reporting to Log Analytics, review Verify agent connectivity to Log Analytics.

Install agent using command line

The downloaded file for the agent is a self-contained installation package. The setup program for the agent and supporting files are contained in the package and need to be extracted in order to properly install using the command line shown in the following examples.

Note

If you want to upgrade an agent, you need to use the Log Analytics scripting API. See the topic Managing and maintaining the Log Analytics agent for Windows and Linux for further information.

The following table highlights the specific parameters supported by setup for the agent, including when deployed using Automation DSC.

MMA-specific optionsNotes
NOAPM=1Optional parameter. Installs the agent without .NET Application Performance Monitoring.
ADD_OPINSIGHTS_WORKSPACE1 = Configure the agent to report to a workspace
OPINSIGHTS_WORKSPACE_IDWorkspace ID (guid) for the workspace to add

Install agent using DSC in Azure Automation

You can use the following script example to install the agent using Azure Automation DSC. If you do not have an Automation account, see Get started with Azure Automation to understand requirements and steps for creating an Automation account required before using Automation DSC. If you are not familiar with Automation DSC, review Getting started with Automation DSC.

The following example installs the 64-bit agent, identified by the URI value. You can also use the 32-bit version by replacing the URI value. The URIs for both versions are:

  • Windows 64-bit agent - https://go.microsoft.com/fwlink/?LinkId=828603
  • Windows 32-bit agent - https://go.microsoft.com/fwlink/?LinkId=828604

Note

This procedure and script example does not support upgrading the agent already deployed to a Windows computer.

The 32-bit and 64-bit versions of the agent package have different product codes and new versions released also have a unique value. The product code is a GUID that is the principal identification of an application or product and is represented by the Windows Installer ProductCode property. The ProductId value in the MMAgent.ps1 script has to match the product code from the 32-bit or 64-bit agent installer package.

To retrieve the product code from the agent install package directly, you can use Orca.exe from the Windows SDK Components for Windows Installer Developers that is a component of the Windows Software Development Kit or using PowerShell following an example script written by a Microsoft Valuable Professional (MVP). For either approach, you first need to extract the MOMagent.msi file from the MMASetup installation package. This is shown earlier in the first step under the section Install the agent using the command line.

  1. Import the xPSDesiredStateConfiguration DSC Module from https://www.powershellgallery.com/packages/xPSDesiredStateConfiguration into Azure Automation.
  2. Create Azure Automation variable assets for OPSINSIGHTS_WS_ID and OPSINSIGHTS_WS_KEY. Set OPSINSIGHTS_WS_ID to your Log Analytics workspace ID and set OPSINSIGHTS_WS_KEY to the primary key of your workspace.
  3. Copy the script and save it as MMAgent.ps1.
  1. Update the ProductId value in the script with the product code extracted from the latest version of the agent install package using the methods recommended earlier.
  2. Import the MMAgent.ps1 configuration script into your Automation account.
  3. Assign a Windows computer or node to the configuration. Within 15 minutes, the node checks its configuration and the agent is pushed to the node.

Verify agent connectivity to Azure Monitor

Once installation of the agent is complete, verifying it is successfully connected and reporting can be accomplished in two ways.

From the computer in Control Panel, find the item Microsoft Monitoring Agent. Select it and on the Azure Log Analytics tab, the agent should display a message stating: The Microsoft Monitoring Agent has successfully connected to the Microsoft Operations Management Suite service.

You can also perform a simple log query in the Azure portal.

  1. In the Azure portal, search for and select Monitor.

  2. Select Logs in the menu.

  3. On the Logs pane, in the query field type:

In the search results returned, you should see heartbeat records for the computer indicating it is connected and reporting to the service.

Cache information

Data from the Log Analytics agent is cached on the local machine at C:Program FilesMicrosoft Monitoring AgentAgentHealth Service State before it's sent to Azure Monitor. The agent attempts to upload every 20 seconds. If it fails, it will wait an exponentially increasing length of time until it succeeds. It will wait 30 seconds before the second attempt, 60 seconds before the next, 120 seconds, and so on to a maximum of 8.5 hours between retries until it successfully connects again. This wait time is slightly randomized to avoid all agents simultaneously attempting connection. Oldest data is discarded when the maximum buffer is reached.

The default cache size is 50 MB but can be configured between a minimum of 5 MB and maximum of 1.5 GB. It's stored in the registry key HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesHealthServiceParametersPersistence Cache Maximum. The value represents the number of pages, with 8 KB per page.

Next steps

  • Review Managing and maintaining the Log Analytics agent for Windows and Linux to learn about how to reconfigure, upgrade, or remove the agent from the virtual machine.

  • Review Troubleshooting the Windows agent if you encounter issues while installing or managing the agent.

Windows Update helps keep your computer up-to-date and secure by downloading and installing the latest security and other updates from Microsoft. Windows Update determines which updates apply to your computer.

Microsoft periodically makes software updates available to users of Windows and other Microsoft software. These include updates that improve reliability and performance, updates that provide new protections against malware and other potentially unwanted software, and upgrades to Windows features. To improve the performance or the reliability of hardware components on the computer, Microsoft may also provide updates to device drivers that are supplied by the computer manufacturer.

If you turn on Windows Update, software components that are directly related to Windows Update will have to be updated occasionally on your computer. These updates must be performed before Windows Update can check for required updates or before it can install other updates. These required updates fix errors, provide ongoing improvements, and maintain compatibility with the Microsoft servers that support Windows Update. If you disable Windows Update, you will not receive these updates.

Windows Update is configured to install updates automatically when you select the recommended option during Windows Out Of Box Experience (OOBE) Setup. You can also turn on Windows Update by selecting one of following settings in the Automatic Updates item in Control Panel:

  • Automatic (recommended).
  • Download updates for me, but let me choose when to install them.
  • Notify me, but don't automatically download or install them.

After you turn on Windows Update, the required updates to components of Windows Update will be downloaded and installed automatically without notifying you. This behavior occurs regardless of which setting you use to turn on Windows Update. If you do not want to receive required updates, you can disable automatic updates in Control Panel.

The updates to Windows Update itself typically do the following: Address feedback from customers, improve compatibility, service performance and reliability, and enable new service capabilities. When the Windows Update server is updated, a corresponding client update is typically required. During an agent self-update operation, Windows Update Agent files may be added, modified, or replaced. For example, Windows Update Agent files that help display the user experience or that determine whether updates apply to a particular system may be added. This behavior occurs when a system is set to automatically check for available updates. This does not occur when automatic updates are turned off. For example, this behavior does not occur if you select Never check for updates in Windows Vista and Windows 7 or if you select Turn off Automatic Updates in Windows XP.

Administrators will receive the latest version of the Windows Update Agent for deployment through Windows Server Update Services (WSUS).
