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

 1 function waitsec{  
 2     $step=10 #设置间隔  
 3     $add=0 #设置延时  
 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",
14     "\Web Service(*)\Maximum Anonymous Users",
15     "\Web Service(*)\Measured Async I/O Bandwidth Usage",
16     "\Web Service(*)\Total Blocked Async I/O Requests",
17     "\Web Service(*)\Total Get Requests",
18     "\Web Service(*)\Total Method Requests",
19     "\Web Service(*)\Total Method Requests/sec",
20     "\Web Service(*)\Total Post Requests",
21     "\Web Service(*)\Total Put Requests",
22     "\Web Service(*)\Delete Requests/sec",
23     "\Web Service(*)\Get Requests/sec",
24     "\Web Service(*)\Options Requests/sec",
25     "\Web Service(*)\Post Requests/sec",
26     "\Web Service(*)\Put Requests/sec",
27     "\Web Service(*)\Other Request Methods/sec",
28     "\HTTP Service Request Queues(*)\CurrentQueueSize",
29     "\HTTP Service Request Queues(*)\RejectedRequests",
30     "\.NET CLR Exceptions(*)\# of Exceps Thrown / sec",
31     "\Process(w3wp*)\Thread Count",
32     "\Process(w3wp*)\% Processor Time",
33     "\Process(w3wp*)\Working Set - Private",
34     "\Process(w3wp*)\Working Set",
35     "\Process(w3wp*)\Private Bytes"
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     #执行代码  
76     get-date  
77     (GetData)
78     #……  
79     Start-Sleep -s (waitsec)  
80 }

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。
