AzureMetrics 表的查询

  • 项目

有关在 Azure 门户中使用这些查询的信息，请参阅 Log Analytics 教程。 有关 REST API，请参阅查询。

HTTP 响应代码的饼图

过去 12 小时内每个指标的响应代码明细。

AzureMetrics 
| where TimeGenerated > ago(12h)  
| where MetricName in ("Http2xx", "Http3xx", "Http4xx", "Http5xx") 
| summarize sum(Total) by MetricName  
| render piechart

响应时间的折线图

平均响应时间（超过 5 分钟间隔）的时序。

AzureMetrics 
| extend timeBin = bin(TimeGenerated, 5m) 
| summarize ResponseTime = sumif(Average, MetricName=="AverageResponseTime") by timeBin, bin(TimeGenerated, 1h) 
| sort by TimeGenerated desc 
| render timechart

[经典] 在 AzureMetrics 中查找

[经典] 在 AzureMetrics 中查找以在 AzureMetrics 表中搜索特定值。/n请注意，此查询需要更新 <SeachValue> 参数，才能生成结果

// This query requires a parameter to run. Enter value in SearchValue to find in table.
let SearchValue =  "<SearchValue>";//Please update term you would like to find in the table.
AzureMetrics
| where * contains tostring(SearchValue)
| take 1000

最新指标

显示每个报告的指标的最新指标报告。

AzureMetrics 
| summarize arg_max(TimeGenerated, UnitName, Total, Count, Maximum, Minimum, Average) by MetricName

平均 CPU 使用率

按资源名称列出的过去一小时平均 CPU 使用率。

//consistently high averages could indicate a customer needs to move to a larger SKU
AzureMetrics
| where ResourceProvider == "MICROSOFT.SQL" // /DATABASES
| where TimeGenerated >= ago(60min)
| where MetricName in ('cpu_percent') 
| parse _ResourceId with * "/microsoft.sql/servers/" Resource  // subtract Resource name for _ResourceId
| summarize CPU_Maximum_last15mins = max(Maximum), CPU_Minimum_last15mins = min(Minimum), CPU_Average_last15mins = avg(Average) by Resource , MetricName

性能故障排除

可能会在系统上查询或死锁，这可能会导致性能不佳。

//potentially a query or deadlock on the system that could lead to poor performance
AzureMetrics
| where ResourceProvider == "MICROSOFT.SQL"
| where TimeGenerated >=ago(60min)
| where MetricName in ('deadlock')
| parse _ResourceId with * "/microsoft.sql/servers/" Resource // subtract Resource name for _ResourceId
| summarize Deadlock_max_60Mins = max(Maximum) by Resource, MetricName

加载数据

监视过去一小时内的数据加载。

AzureMetrics
| where ResourceProvider == "MICROSOFT.SQL"
| where TimeGenerated >= ago(60min)
| where MetricName in ('log_write_percent')
| parse _ResourceId with * "/microsoft.sql/servers/" Resource// subtract Resource name for _ResourceId
| summarize Log_Maximum_last60mins = max(Maximum), Log_Minimum_last60mins = min(Minimum), Log_Average_last60mins = avg(Average) by Resource, MetricName
