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 $commandSet38 $index=039 $metricAppName=""40 $timestamp=[int] (Get-Date (Get-Date).ToUniversalTime() -uformat "%s")41 $host_name = hostname42 $table_name=""43 while($res.countersamples[$index])44 { 45 $Metrics1=@{}46 $value= $res.countersamples[$index].cookedvalue 47 $metric=$res.countersamples[$index].path 48 $metricAppName=$res.countersamples[$index].InstanceName49 $tempArray=$metric.replace("\\","").split("\")50 $metric=$tempArray[2]51 $Metrics1.$metric = $value52 if($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:909669 $index = $index + 170 }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。
