Summary

This article describes how to enable debug logging (also known as ETL tracing) for Microsoft Azure Site Recovery (ASR) in Hyper-V Site to Azure protection scenarios running on a Windows Server 2012 R2 Hyper-V server. You may use the steps in this article for ASR configured using the Setup Recovery Between an on-premises Hyper-V site and Azure option in the Azure Management Portal. ASR installations that use Microsoft System Center 2012 R2 Virtual Machine Manager (SC 2012 R2 VMM) should enable VMM Debug Logging instead.

Note

This functionality is enabled by default in the Support Diagnostic Package (SDP) for ASR in Hyper-V. The tool can be downloaded from this link.

More information

To enable debug logging for the ASR Provider, use the following steps:

  1. Open an elevated PowerShell Window and then run the following commands to create your trace definition:

    logman create trace ASRDebug -v mmddhhmm -o C:\temp\asr.etl -cnf 01:00:00 -nb 10 250 -bs 16 -ow -y
logman update ASRDebug -p "Microsoft-Azure Site Recovery-Provider" 0x8000000000000000 0x5
logman update ASRDebug -p "MicrosoftAzureRecoveryServices" 0xC000000000000000 0x5

    Note

    The default location specified above is C:\temp. You may safely change this value if needed. The folder will be created if it does not exist.

  2. Start the trace by typing the following command in the elevated Windows PowerShell window:

    logman start ASRDebug

  3. Reproduce your issue.

  4. As soon as you reproduce your issue, stop the trace by running the following command:

    logman stop ASRDebug

  5. Convert the trace to readable text, run the following command:

    netsh trace convert <filename>

    Note

    In this command, the placeholder < filename > represents the name of the ETL that you found in step 5. The converted trace file will have a name in the format < filename >.txt.

  6. Collect debug logs from the folder <installation folder>\Temp. The default location will be C:\Program Files\Microsoft Azure Recovery Services Agent\Temp.

  7. Use these steps to collect SRS logs from the Azure Site Recovery portal:

    1. Log on to the Azure portal.
    2. Select Recovery Services vaults.
    3. Select the vault that hosts your ASR data.
    4. Select Site Recovery jobs.
    5. Select Export Jobs to begin the export process.
    6. Specify a file location, and then click Save to export the job details to an .xlsx file.

  8. Run the following command:

    wevtutil el | findstr /i microsoftazurerecoveryservices-replication | % { wevtutil qe $_ /f:text}

  9. Run the following PowerShell command to collect Hyper-V logs:

    wevtutil el | findstr /i hyper-v-vmms | % { wevtutil qe $_ /f:text}

  10. Run the following PowerShell command to collect Hyper-V logs:

    wevtutil el | findstr /i "microsoft-azure site recovery-provider" | % { wevtutil qe $_ /f:text}
