如何用PowerShell解析Prometheus prom格式并转为PowerShell对象？

我一直在寻找如何使用PowerShell解析Prometheus的prom格式响应，将已发布的Windows系统性能指标转换为PowerShell对象。

示例prom格式内容 #

# HELP CPU_Total Total CPU load in percent of all processors combined.
# TYPE CPU_Total gauge
CPU_Total{Instance="_total"} 1.29915
# HELP Disk_Avg_Bytes_Read Average number of bytes transfered from the disk during read operations.
# TYPE Disk_Avg_Bytes_Read gauge
Disk_Avg_Bytes_Read{Instance="harddiskvolume2"} 0
# HELP Disk_Avg_Bytes_Read Average number of bytes transfered from the disk during read operations.
# TYPE Disk_Avg_Bytes_Read gauge
Disk_Avg_Bytes_Read{Instance="c"} 0
# HELP Disk_Avg_Bytes_Read Average number of bytes transfered from the disk during read operations.
# TYPE Disk_Avg_Bytes_Read gauge
Disk_Avg_Bytes_Read{Instance="_total"} 0
# HELP Disk_Avg_Bytes_Write Average number of bytes transfered to the disk during write operations.
# TYPE Disk_Avg_Bytes_Write gauge
Disk_Avg_Bytes_Write{Instance="harddiskvolume2"} 0
# HELP Disk_Avg_Bytes_Write Average number of bytes transfered to the disk during write operations.
# TYPE Disk_Avg_Bytes_Write gauge
Disk_Avg_Bytes_Write{Instance="c"} 8192
# HELP Disk_Avg_Bytes_Write Average number of bytes transfered to the disk during write operations.
# TYPE Disk_Avg_Bytes_Write gauge
Disk_Avg_Bytes_Write{Instance="_total"} 8192
# HELP Disk_sec_per_Read Average time, in seconds, of a read of data from the disk.
# TYPE Disk_sec_per_Read gauge
Disk_sec_per_Read{Instance="harddiskvolume2"} 0

尝试情况说明 #

• 已有Go、C#等语言的解析示例，多基于Google ProtoBuf库，但我不熟悉C#编写，PowerShell调用.NET版ProtoBuf公开方法难度大，还需借助DLL浏览器查找可用调用名称。
• 尝试用Install-Package安装.NET版ProtoBuf及依赖时，出现如下错误：

  Install-Package: Dependency loop detected for package 'protobuf-net'
  

  但使用choco install protoc可成功安装。
• Prometheus已不再支持JSON格式，对应的proto文件也不再维护（未来可能恢复维护）。
• 后续尝试：
  • 转而使用Chocolatey安装相关库
  • 发现ProtoBuf库实际是带有命令行参数的protoc.exe文件
  • 找到Prometheus的ebnf规范
  • 补充了上述prom格式示例内容

请问是否有基于prom文件在PowerShell中构建解析器的简便方法？
