asp.net 网站监控方案

前言：监控web网站方法有很多种，这篇文章说一下对windows服务器 asp.net网站的监控

采用的方案，Powershell + Influxdb + Grafana

1、PowerShell + Influxdb

PowerShell用来收集IIS指标，10秒采集一次，然后写入Influxdb,主要代码如下：需要注意PowerShell需要升级到5.0才能支持influxdb

标签分别是：Server主机名 ,AppName是网站名称

 function waitsec{
     $step= #设置间隔
     $add= #设置延时
     $t=(get-date)
     $step-(($t.Hour*+$t.Minute*+$t.Second)%$step)+$add
 }
 function GetData($cluster,$dept,$group,$project,$type)
 {
     $commandSet=@(
     "\Web Service(*)\Current Anonymous Users",
     "\Web Service(*)\Current Connections",
     "\Web Service(*)\Current NonAnonymous Users",
     "\Web Service(*)\Current Blocked Async I/O Requests",
     "\Web Service(*)\Maximum Anonymous Users",
     "\Web Service(*)\Measured Async I/O Bandwidth Usage",
     "\Web Service(*)\Total Blocked Async I/O Requests",
     "\Web Service(*)\Total Get Requests",
     "\Web Service(*)\Total Method Requests",
     "\Web Service(*)\Total Method Requests/sec",
     "\Web Service(*)\Total Post Requests",
     "\Web Service(*)\Total Put Requests",
     "\Web Service(*)\Delete Requests/sec",
     "\Web Service(*)\Get Requests/sec",
     "\Web Service(*)\Options Requests/sec",
     "\Web Service(*)\Post Requests/sec",
     "\Web Service(*)\Put Requests/sec",
     "\Web Service(*)\Other Request Methods/sec",
     "\HTTP Service Request Queues(*)\CurrentQueueSize",
     "\HTTP Service Request Queues(*)\RejectedRequests",
     "\.NET CLR Exceptions(*)\# of Exceps Thrown / sec",
     "\Process(w3wp*)\Thread Count",
     "\Process(w3wp*)\% Processor Time",
     "\Process(w3wp*)\Working Set - Private",
     "\Process(w3wp*)\Working Set",
     "\Process(w3wp*)\Private Bytes"
     )
     $res= get-counter -counter $commandSet
     $index=
     $metricAppName=""
     $timestamp=[int] (Get-Date (Get-Date).ToUniversalTime() -uformat "%s")
     $host_name = hostname
     $table_name=""
     while($res.countersamples[$index])
     {
         $Metrics1=@{}
         $value= $res.countersamples[$index].cookedvalue
         $metric=$res.countersamples[$index].path
         $metricAppName=$res.countersamples[$index].InstanceName
         $tempArray=$metric.replace("\\","").split("\")
         $metric=$tempArray[]
         $Metrics1.$metric = $value
         if($tempArray[].startswith('web service'))
         {
             $table_name = "iis_web_service"
         }
         Elseif($tempArray[].startswith('http service'))
         {
             $table_name = "iis_http_service"
         }
         Elseif($tempArray[].startswith('.net clr exceptions'))
         {
             $table_name = "iis_net_clr_exceptions"
         }
         Elseif($tempArray[].startswith('process(w3wp'))
         {
             $table_name = "iis_process"
         }
            Write-Influx -Measure $table_name -Tags @{Server = $host_name;  AppName = $metricAppName;} -Metrics $Metrics1 -Database monitor -Server http://influxdb:9096
         $index = $index +
     }
 }
 write-host "running...... please wait" (waitsec)"S"
 Start-Sleep -s (waitsec)
 while(){
     #执行代码
     get-date
     (GetData)
     #……
     Start-Sleep -s (waitsec)
 }

写入influxdb后的iis_http_service表的数据格式：

2、Grafana 配置展示

这里主要对webapi展示了当前连接数，当前排队数，和请求速率。

整体效果：

还可以在grafana告警里面设置一个WebHook，进行处理告警后的逻辑，比如：当这台机器压力比较大时可以对其进行从负载均衡移除 等等。
