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=@(

37     $res= get-counter -counter $commandset
38     $index=0

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。
