本文介绍如何解决指示 System Center Operations Manager 2025 不支持 Azure Linux 的错误。

问题：在 System Center Operations Manager 2025 中，尝试发现在 Azure 中运行的 Linux 计算机时可能会遇到错误。

错误消息 - 不支持 Azure Linux 和 Arc Linux 计算机。

错误消息的屏幕截图。

注释

此解决方法仅适用于 System Center Operations Manager 2025。如果在 SCOM 托管实例中遇到此错误，请参阅监视 Linux 计算机，因为 SCOM 托管实例不支持监视 Azure Linux VM。

解决方法：

若要解决此错误，请在 Linux 资源池中的所有管理服务器上执行以下作：

复制以下脚本，并将其替换为位于 UnixAgents 目录中 的 GetOSVersion.sh 文件的内容 - C:\Program Files\Microsoft System Center\Operations Manager\Server\AgentManagement\UnixAgents\。

Hostname=`uname -n`
OSName=`uname -s`
Version=`uname -r`  # Version command for Unix; For Linux we look in /etc/issue
Arch=`uname -m`     # Overridden as uname -p on some platforms
OSAlias="Unknown"   # OSAlias is used by discovery wizard
IsLinux="false"     # Used by the discovery wizard for workflow
ReleaseFile=`echo $PLATFORM_RELEASE_FILE_SCX_INSTALLER_INPUT`
EtcPath="/etc"
