asp.net 網站監控方案

  前言：監控web網站方法有很多種，這篇文章說一下對windows伺服器 asp.net網站的監控

 採用的方案，Powershell + Influxdb + Grafana

1、PowerShell + Influxdb

 PowerShell用來收集IIS指標，10秒採集一次，然後寫入Influxdb,主要代碼如下：需要註意PowerShell需要升級到5.0才能支持influxdb

 標簽分別是：Server主機名 ,AppName是網站名稱

 1 function waitsec{  
 2     $step=10 #設置間隔  
 3     $add=0 #設置延時  
 4     $t=(get-date)  
 5     $step-(($t.Hour*3600+$t.Minute*60+$t.Second)%$step)+$add  
 6 }  
 7 function GetData($cluster,$dept,$group,$project,$type)
 8 {
 9     $commandSet=@(
10     "\Web Service(*)\Current Anonymous Users",
11     "\Web Service(*)\Current Connections",
12     "\Web Service(*)\Current NonAnonymous Users",
13     "\Web Service(*)\Current Blocked Async I/O Requests",

36     )
37     $res= get-counter -counter $commandSet
38     $index=0
39     $metricAppName=""
40     $timestamp=[int] (Get-Date (Get-Date).ToUniversalTime() -uformat "%s")
41     $host_name = hostname
42     $table_name=""
43     while($res.countersamples[$index])
44     { 
45         $Metrics1=@{}
46         $value= $res.countersamples[$index].cookedvalue  
47         $metric=$res.countersamples[$index].path 
48         $metricAppName=$res.countersamples[$index].InstanceName
49         $tempArray=$metric.replace("\\","").split("\")
50         $metric=$tempArray[2]
51         $Metrics1.$metric = $value
52         if($tempArray[1].startswith('web service'))
53         {   
54             $table_name = "iis_web_service"
55         }
56         Elseif($tempArray[1].startswith('http service'))
57         {
58             $table_name = "iis_http_service"
59         }
60         Elseif($tempArray[1].startswith('.net clr exceptions'))
61         {
62             $table_name = "iis_net_clr_exceptions"
63         }
64         Elseif($tempArray[1].startswith('process(w3wp'))
65         {
66             $table_name = "iis_process"
67         }
68            Write-Influx -Measure $table_name -Tags @{Server = $host_name;  AppName = $metricAppName;} -Metrics $Metrics1 -Database monitor -Server http://influxdb:9096
69         $index = $index + 1
70     }
71 }
72 write-host "running...... please wait" (waitsec)"S"
73 Start-Sleep -s (waitsec) 
74 while(1){  
75     #執行代碼  
76     get-date  
77     (GetData)
78     #……  
79     Start-Sleep -s (waitsec)  
80 }

寫入influxdb後的iis_http_service表的數據格式：

2、Grafana 配置展示

這裡主要對webapi展示了當前連接數，當前排隊數，和請求速率。

整體效果：

還可以在grafana告警裡面設置一個WebHook，進行處理告警後的邏輯，比如：當這台機器壓力比較大時可以對其進行從負載均衡移除 等等。
