日志分析查询特定磁盘（LUN）

发布于 2025-02-07 15:40:35 字数 349 浏览 3 评论 0原文

嗨，我正在尝试查询特定的磁盘吞吐量，但找不到必须输入的特定值才能从该特定磁盘中获取吞吐量图。那甚至可能吗？

这就是我到目前为止所拥有的：

Perf
 | where ObjectName == "LogicalDisk"
 | where CounterName == "Disk Bytes/sec"
 | where Computer contains "computername"
 | summarize ThroughputInMBs = (max(CounterValue)/1024/1024) by Computer, bin(TimeGenerated, 5m)
 | render timechart

原文

Hi I'm trying to query a specific disk Throughput but cannot find the specific value that has to be input to get the throughput chart from that specific disk. Is that even possible?

This is what I have until now:

Perf
 | where ObjectName == "LogicalDisk"
 | where CounterName == "Disk Bytes/sec"
 | where Computer contains "computername"
 | summarize ThroughputInMBs = (max(CounterValue)/1024/1024) by Computer, bin(TimeGenerated, 5m)
 | render timechart

您可以在查询中添加以下行以过滤特定的VM。

| where Computer == "<Your Disk Name>"

中获取特定磁盘详细信息的最终查询

Perf
 | where Computer == "VM1"
 | where ObjectName == "LogicalDisk"
 | where CounterName == "Disk Bytes/sec"
 | summarize ThroughputInMBs = (avg(CounterValue)/1024/1024) by Computer, bin(TimeGenerated, 5m)
 | render timechart

在日志分析工作空间结果

You can add the below line in your query to filter the specific VM.

| where Computer == "<Your Disk Name>"

Final Query to fetch specific Disk details in a Log Analytic Workspace

Perf
 | where Computer == "VM1"
 | where ObjectName == "LogicalDisk"
 | where CounterName == "Disk Bytes/sec"
 | summarize ThroughputInMBs = (avg(CounterValue)/1024/1024) by Computer, bin(TimeGenerated, 5m)
 | render timechart
