Troubleshoot dependency visualization

This article helps you troubleshoot issues with agent-based and agentless dependency analysis, which is only available for VMware servers. Learn more about the types of dependency visualization supported in Azure Migrate.

Visualize dependencies for >1 hour with agentless dependency analysis

With agentless dependency analysis, you can visualize dependencies or export them in a map for a duration of up to 30 days.

Visualize dependencies for >10 servers with agentless dependency analysis

Azure Migrate offers a Power BI template that you can use to visualize network connections of many servers at once, and filter by process and server. Learn more about how to visualize the dependencies for many servers together.

Dependencies export CSV shows "Unknown process" with agentless dependency analysis

In agentless dependency analysis, the process names are captured on a best-effort basis. In certain scenarios, although the source and destination server names and the destination port are captured, it isn't feasible to determine the process names at both ends of the dependency. In such cases, the process is marked as "Unknown process."

Unable to export dependency data in a CSV due to the error "403: This request is not authorized to perform this operation"

If your Azure Migrate project has private endpoint connectivity, the request to export dependency data should be initiated from a client connected to the Azure virtual network over a private network. To resolve this error, open the Azure portal in your on-premises network or on your appliance server and try exporting again.

Export the dependency analysis errors

You can export all the errors and remediations for agentless dependency analysis from the portal by selecting Export notifications. The exported CSV file also contains additional information like the timestamp at which the error was encountered and if it was an error in validation or discovery of dependency data.

Common agentless dependency analysis errors

Azure Migrate supports agentless dependency analysis by using Azure Migrate: Discovery and assessment. Learn more about how to perform agentless dependency analysis.

For VMware VMs, agentless dependency analysis is performed by connecting to the servers via the vCenter Server using the VMware APIs. For Hyper-V VMs and physical servers, agentless dependency analysis is performed by directly connecting to Windows servers using PowerShell remoting on port 5985 (HTTP) and to Linux servers using SSH connectivity on port 22 (TCP).

The table below summarizes all errors encountered when gathering dependency data through VMware APIs or by directly connecting to servers:

Note

The same errors can also be encountered with software inventory because it follows the same methodology as agentless dependency analysis to collect the required data.

Error	Cause	Action
60001:UnableToConnectToPhysicalServer	Either the prerequisites to connect to the server have not been met or there are network issues in connecting to the server, for instance some proxy settings.	- Ensure that the server meets the prerequisites and port access requirements. - Add the IP addresses of the remote machines (discovered servers) to the WinRM TrustedHosts list on the Azure Migrate appliance, and retry the operation. This is to allow remote inbound connections on servers - Windows: WinRM port 5985 (HTTP) and Linux: SSH port 22 (TCP). - Ensure that you have chosen the correct authentication method on the appliance to connect to the server. - If the issue persists, submit a Microsoft support case, providing the appliance machine ID (available in the footer of the appliance configuration manager).
60002:InvalidServerCredentials	Unable to connect to server. Either you have provided incorrect credentials on the appliance or the credentials previously provided have expired.	- Ensure that you have provided the correct credentials for the server on the appliance. You can check that by trying to connect to the server using those credentials. - If the credentials added are incorrect or have expired, edit the credentials on the appliance and revalidate the added servers. If the validation succeeds, the issue is resolved. - If the issue persists, submit a Microsoft support case, providing the appliance machine ID (available in the footer of the appliance configuration manager).
60005:SSHOperationTimeout	The operation took longer than expected either due to network latency issues or due to the lack of latest updates on the server.	- Ensure that the impacted server has the latest kernel and OS updates installed. - Ensure that there is no network latency between the appliance and the server. It is recommended to have the appliance and source server on the same domain to avoid latency issues. - Connect to the impacted server from the appliance and run the commands documented here to check if they return null or empty data. - If the issue persists, submit a Microsoft support case providing the appliance machine ID (available in the footer of the appliance configuration manager).

Error 970: DependencyMapInsufficientPrivilegesException

Cause

The error usually appears for Linux servers when you haven't provided credentials with the required privileges on the appliance.

Remediation

You have two options:

• Ensure that you've provided a root user account.
• Ensure that an account has these permissions on /bin/netstat and /bin/ls files:
  • CAP_DAC_READ_SEARCH
  • CAP_SYS_PTRACE

To check if the user account provided on the appliance has the required privileges:

1. Log in to the server where you encountered this error with the same user account as mentioned in the error message.

2. Run the following commands in Azure Shell. You'll get errors if you don't have the required privileges for agentless dependency analysis.

   ps -o pid,cmd | grep -v ]$
   netstat -atnp | awk '{print $4,$5,$7}'
   

3. Set the required permissions on /bin/netstat and /bin/ls files by running the following commands:

   sudo setcap CAP_DAC_READ_SEARCH,CAP_SYS_PTRACE=ep /bin/ls
   sudo setcap CAP_DAC_READ_SEARCH,CAP_SYS_PTRACE=ep /bin/netstat
   

4. You can validate if the preceding commands assigned the required permissions to the user account or not.

   getcap /usr/bin/ls
   getcap /usr/bin/netstat
   

5. Rerun the commands provided in step 2 to get a successful output.

Error 9014: HTTPGetRequestToRetrieveFileFailed

Cause

The issue happens when the VMware discovery agent in appliance tries to download the output file containing dependency data from the server file system through the ESXi host on which the server is hosted.

Remediation

• You can test TCP connectivity to the ESXi host (name provided in the error message) on port 443 (required to be open on ESXi hosts to pull dependency data) from the appliance. Open PowerShell on the appliance server and run the following command:

  Test -NetConnection -ComputeName <Ip address of the ESXi host> -Port 443
  

• If the command returns successful connectivity, go to the Azure Migrate project > Discovery and assessment > Overview > Manage > Appliances, select the appliance name, and select Refresh services.

Error 9018: PowerShellNotFound

Cause

The error usually appears for servers running Windows Server 2008 or lower.

Remediation

Install Windows PowerShell 5.1 at this location on the server. Follow the instructions in Install and Configure WMF 5.1 to install PowerShell in Windows Server.

After you install the required PowerShell version, verify if the error was resolved by following the steps on this website.

Error 9022: GetWMIObjectAccessDenied

Remediation

Make sure that the user account provided in the appliance has access to the WMI namespace and subnamespaces. To set the access:

1. Go to the server that's reporting this error.
2. Search and select Run from the Start menu. In the Run dialog, enter wmimgmt.msc in the Open text box, and select Enter.
3. The wmimgmt console opens where you can find WMI Control (Local) in the left pane. Right-click it, and select Properties from the menu.
4. In the WMI Control (Local) Properties dialog, select the Securities tab.

10. Ensure you grant execute permissions, and select This namespace and subnamespaces in the Applies to dropdown list.
11. Select Apply to save the settings and close all dialogs.

After you get the required access, verify if the error was resolved by following the steps on this website.

Error 9032: InvalidRequest

Cause

There can be multiple reasons for this issue. One reason is when the username provided (server credentials) on the appliance configuration manager has invalid XML characters. Invalid characters cause an error in parsing the SOAP request.

Remediation

• Make sure the username of the server credentials doesn't have invalid XML characters and is in the username@domain.com format. This format is popularly known as the UPN format.
• After you edit the credentials on the appliance, verify if the error was resolved by following the steps on this website.

Error 10002: ScriptExecutionTimedOutOnVm

Cause

• This error occurs when the server is slow or unresponsive and the script executed to pull the dependency data starts timing out.
• After the discovery agent encounters this error on the server, the appliance doesn't attempt agentless dependency analysis on the server thereafter to avoid overloading the unresponsive server.
• You'll continue to see the error until you check the issue with the server and restart the discovery service.

Remediation

1. Log in to the server that's encountering this error.

2. Run the following commands on PowerShell:

   Get-WMIObject win32_operatingsystem;
   Get-WindowsFeature  | Where-Object {$_.InstallState -eq 'Installed' -or ($_.InstallState -eq $null -and $_.Installed -eq 'True')};
   Get-WmiObject Win32_Process;
   netstat -ano -p tcp | select -Skip 4;
   

3. If commands output the result in a few seconds, go to the Azure Migrate project > Discovery and assessment > Overview > Manage > Appliances, select the appliance name, and select Refresh services to restart the discovery service.

4. If the commands are timing out without giving any output, you need to:

   • Figure out which processes are consuming high CPU or memory on the server.
   • Try to provide more cores or memory to that server and run the commands again.

Error 10005: GuestCredentialNotValid

Remediation

• Ensure the validity of credentials (friendly name provided in the error) by selecting Revalidate credentials on the appliance configuration manager.
• Ensure that you can log in to the affected server by using the same credential provided in the appliance.
• You can try using another user account (for the same domain, in case the server is domain joined) for that server instead of the administrator account.
• The issue can happen when Global Catalog <-> Domain Controller communication is broken. Check for this problem by creating a new user account in the domain controller and providing the same in the appliance. You might also need to restart the domain controller.
• After you take the remediation steps, verify if the error was resolved by following the steps on this website.

Error 10012: CredentialNotProvided

Cause

This error occurs when you've provided a domain credential with the wrong domain name on the appliance configuration manager. For example, if you've provided domain credentials with the username user@abc.com but provided the domain name as def.com, those credentials won't be attempted if the server is connected to def.com and you'll get this error message.

Remediation

• Go to the appliance configuration manager to add a server credential or edit an existing one as explained in the cause.
• After you take the remediation steps, verify if the error was resolved by following the steps on this website.

Mitigation verification

After you use the mitigation steps for the preceding errors, verify if the mitigation worked by running a few PowerCLI commands from the appliance server. If the commands succeed, it means that the issue is resolved. Otherwise, check and follow the remediation steps again.

My Log Analytics workspace isn't listed when you try to configure the workspace in Azure Migrate for agent-based dependency analysis

Azure Migrate currently supports creation of OMS workspace in East US, Southeast Asia, and West Europe regions. If the workspace is created outside of Azure Migrate in any other region, it currently can't be associated with a project.

Agent-based dependency visualization in Azure Government

Agent-based dependency analysis isn't supported in Azure Government. Use agentless dependency analysis, which is only available for VMware servers.

Agent-based dependencies don't show after agent installation

After you've installed the dependency visualization agents on on-premises VMs, Azure Migrate typically takes 15 to 30 minutes to display the dependencies in the portal. If you've waited for more than 30 minutes, make sure that the Microsoft Monitoring Agent (MMA) can connect to the Log Analytics workspace.

For Windows VMs:

1. In the Control Panel, start MMA.

2. In Microsoft Monitoring Agent properties > Azure Log Analytics (OMS), make sure that the Status for the workspace is green.

3. If the status isn't green, try removing the workspace and adding it again to MMA.

   

For Linux VMs, make sure that the installation commands for MMA and the dependency agent succeeded. Refer to more troubleshooting guidance on this website.

Supported operating systems for agent-based dependency analysis

• MMS agent: The supported Windows and Linux operating systems.
• Dependency agent: The supported Windows and Linux operating systems.

Visualize dependencies for >1 hour with agent-based dependency analysis

With agent-based dependency analysis, although Azure Migrate allows you to go back to a particular date in the last month, the maximum duration for which you can visualize the dependencies is one hour. For example, you can use the time duration functionality in the dependency map to view dependencies for yesterday, but you can view them for a one-hour period only. You can use Azure Monitor logs to query the dependency data over a longer duration.

Visualize dependencies for >10 servers with agent-based dependency analysis

In Azure Migrate, with agent-based dependency analysis, you can visualize dependencies for groups with up to 10 VMs. For larger groups, split the VMs into smaller groups to visualize dependencies.

Servers show "Install agent" for agent-based dependency analysis

After you migrate servers with dependency visualization enabled to Azure, servers might show the Install agent action instead of View dependencies because of the following behavior:

• After migration to Azure, on-premises servers are turned off and equivalent VMs are spun up in Azure. These servers acquire a different MAC address.
• Servers might also have a different IP address, based on whether you've retained the on-premises IP address or not.
• If both MAC and IP addresses are different from on-premises, Azure Migrate doesn't associate the on-premises servers with any Service Map dependency data. In this case, it shows the option to install the agent rather than to view dependencies.
• After a test migration to Azure, on-premises servers remain turned on as expected. Equivalent servers spun up in Azure acquire different MAC addresses and might acquire different IP addresses. Unless you block outgoing Azure Monitor log traffic from these servers, Azure Migrate won't associate the on-premises servers with any Service Map dependency data. In this case, it shows the option to install agents rather than to view dependencies.

Capture network traffic

To collect network traffic logs:

1. Sign in to the Azure portal.
2. Select F12 to start Developer Tools. If needed, clear the Clear entries on navigation setting.
3. Select the Network tab, and start capturing network traffic:
   • In Chrome, select Preserve log. The recording should start automatically. A red circle indicates that traffic is being captured. If the red circle doesn't appear, select the black circle to start.
   • In Microsoft Edge and Internet Explorer, the recording should start automatically. If it doesn't, select the green play button.
4. Try to reproduce the error.
5. After you encounter the error while recording, stop recording, and save a copy of the recorded activity:
   • In Chrome, right-click and select Save as HAR with content. This action compresses and exports the logs as an HTTP Archive (har) file.
   • In Microsoft Edge or Internet Explorer, select the Export captured traffic option. This action compresses and exports the log.
6. Select the Console tab to check for any warnings or errors. To save the console log:
   • In Chrome, right-click anywhere in the console log. Select Save as to export, and zip the log.
   • In Microsoft Edge or Internet Explorer, right-click the errors and select Copy all.
7. Close Developer Tools.
