一、簡介
很久之前寫了一篇 《.Net Core 2.0+ InfluxDB+Grafana+App Metrics 實現跨平臺的實時性能監控》關於NetCore性能監控的文章,使用Influxdb+AppMetrics進行項目性能監控,由於技術有限,在正式環境使用一段時間後,莫名的AppMetrics就沒辦法往influxdb中插入數據了,後來我也在App Metrics作者的github上留言了,並且作者也根據我闡述的情況做了測試,沒有復現我的問題,最後這個問題就不了了知了,然後項目性能監控這個事擱置了一段時間,直到2018年參加上海.net線下技術沙龍,在會場首次聽到skywalking,那時候skywalking正在做NetCore的支持,會後回到公司便開始關註skywalking,知道skywalking支持NetCore後,第一時間在公司的項目中運用了skywalking。
二、安裝環境
要想使用skywalking,首先得安裝相關環境。本文以windows為例。
1、安裝java sdk(如果不會配置java環境的話,請參考百度百科:https://jingyan.baidu.com/article/08b6a591bdb18314a80922a0.html)
2、java環境安裝完成後,下載Elasticsearch進行安裝 https://www.elastic.co/downloads/elasticsearch (本文使用skywalking 6.x版本,6.x版本對應使用ES 6.x版本,請自行下載對應版本)
3、下載完Elasticsearch 後將Elasticsearch解壓到安裝位置,以我電腦為例,我安裝在D:\Program Files
4、修改ES配置,進入ES文件下的:\config,找到elasticsearch.yml,打開後修改如下配置:

1 # ======================== Elasticsearch Configuration ========================= 2 # 3 # NOTE: Elasticsearch comes with reasonable defaults for most settings. 4 # Before you set out to tweak and tune the configuration, make sure you 5 # understand what are you trying to accomplish and the consequences. 6 # 7 # The primary way of configuring a node is via this file. This template lists 8 # the most important settings you may want to configure for a production cluster. 9 # 10 # Please consult the documentation for further information on configuration options: 11 # https://www.elastic.co/guide/en/elasticsearch/reference/index.html 12 # 13 # ---------------------------------- Cluster ----------------------------------- 14 # 15 # Use a descriptive name for your cluster: 16 # 17 cluster.name: myskywalking 18 # 19 # ------------------------------------ Node ------------------------------------ 20 # 21 # Use a descriptive name for the node: 22 # 23 node.name: node-1 24 # 25 # Add custom attributes to the node: 26 # 27 #node.attr.rack: r1 28 # 29 # ----------------------------------- Paths ------------------------------------ 30 # 31 # Path to directory where to store the data (separate multiple locations by comma): 32 # 33 path.data: D:/Program Files/elasticsearch-6.6.2/path/to/data 34 # 35 # Path to log files: 36 # 37 path.logs: D:/Program Files/elasticsearch-6.6.2/path/to/logs 38 # 39 # ----------------------------------- Memory ----------------------------------- 40 # 41 # Lock the memory on startup: 42 # 43 bootstrap.memory_lock: false 44 # 45 # Make sure that the heap size is set to about half the memory available 46 # on the system and that the owner of the process is allowed to use this 47 # limit. 48 # 49 # Elasticsearch performs poorly when the system is swapping the memory. 50 # 51 # ---------------------------------- Network ----------------------------------- 52 # 53 # Set the bind address to a specific IP (IPv4 or IPv6): 54 # 55 network.host: 0.0.0.0 56 http.port: 9200 57 http.cors.enabled: true 58 http.cors.allow-origin: "*" 59 http.cors.allow-methods: OPTIONS,HEAD,GET,POST,PUT,DELETE 60 http.cors.allow-headers: "X-Requested-With, Content-Type, Content-Length, X-Users" 61 62 # 63 # For more information, consult the network module documentation. 64 # 65 # --------------------------------- Discovery ---------------------------------- 66 # 67 # Pass an initial list of hosts to perform discovery when new node is started: 68 # The default list of hosts is ["127.0.0.1", "[::1]"] 69 # 70 #discovery.zen.ping.unicast.hosts: ["host1", "host2"] 71 # 72 # Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1): 73 # 74 #discovery.zen.minimum_master_nodes: 75 # 76 # For more information, consult the zen discovery module documentation. 77 # 78 # ---------------------------------- Gateway ----------------------------------- 79 # 80 # Block initial recovery after a full cluster restart until N nodes are started: 81 # 82 #gateway.recover_after_nodes: 3 83 # 84 # For more information, consult the gateway module documentation. 85 # 86 # ---------------------------------- Various ----------------------------------- 87 # 88 # Require explicit names when deleting indices: 89 # 90 #action.destructive_requires_name: trueView Code
修改好elasticsearch.yml文件後,打開cmd命令,進入到D:\Program Files\elasticsearch-6.6.2\bin,bin文件夾下,輸入如下命令: elasticsearch-service.bat install 將ES安裝成windows,這樣就可以方便系統重啟後自動啟動
然後將服務啟動後即可
5、接下來下載skywalking,http://skywalking.apache.org/downloads/
選擇版本為 :6.0.0-GA 的下載
三、配置和效果
1、在本地電腦中創建一個文件夾(註意:本人親自躺過的坑,skywalking服務必須放在無空格的文件夾,比如:Program Files這個文件是絕對不能放的,不然服務運行的時候只會一閃而過,連log日誌都不會生成,切記!切記!切記!)
我在D盤下創建了一個叫skyworkingService文件,路徑如下:D:\skyworkingService
將下好的skywalking解壓到該目錄下,命名為skywalking-apm-GA,路徑如下:D:\skyworkingService\skywalking-apm-GA
接著,打開config文件,找到application.yml文件,修改其配置如下:

修改完成後,進入到bin文件中,右鍵單擊startup.bat,以管理員許可權運行,即可看到如下彈框
彈出這兩個框說明服務已經啟動了
這個時候訪問http://localhost:8080,即可看到如下界面:
預設賬號admin,密碼admin,登錄後看看到想要的監控數據和各服務直接的拓撲圖,因為我的服務跑了一段時間,所以下麵的界面是有數據的:
2、由於啟動skywalking後會彈出兩個命令視窗,所以如果運維人員不小心關了視窗的話服務自然就停掉了,所以為了避免這種問題,我們還可以將bin文件夾下的oapService.bat和webappService.bat進行配置,如下:

其實只是將文件里的java改成了javaw,這樣就可以在後臺運行了,保存後再次運行startup.bat文件,這個時候界面上會有個cmd命令界面一閃而過,不要慌,我們打開資源管理器看看,會發現進程中多了兩個名為“javaw.exe”的進程
這個時候訪問:http://localhost:8080 一樣可以看到上面的ui界面!
至此,skywalking的所有環境皆搭建完畢,接下來,在我們項目中添加skywalking的探針,方便skywalking收集我們項目中的數據
四、項目引用skywalking探針
新建一個NetCore的webapi,然後在引用中引用 SkyWalking.AspNetCore(已過期)SkyAPM.Agent.AspNetCore 0.8.0 如圖:
項目引用後,在項目中添加環境變數,可以使用skywalking 官網使用說明書中的命令,進入項目文件夾,給項目配置環境變數並運行
(
set ASPNETCORE_HOSTINGSTARTUPASSEMBLIES=SkyAPM.Agent.AspNetCore set SKYWALKING__SERVICENAME=sample_app dotnet run
)
也可以自己手動給項目添加環境變數,本文以給項目添加環境變數為例:
在項目的Properties下找到launchSettings.json,按上圖所示,在environmentVariables節點下分別添加一下環境變數:
"ASPNETCORE_HOSTINGSTARTUPASSEMBLIES": "SkyAPM.Agent.AspNetCore",
"SKYWALKING__SERVICENAME": "sample_app"
添加完環境變數後,打開cmd,進入到項目根目錄(比如我項目是在F:\NEW_TMS\OtherProject\V1.0\XiangYu.AreaModules\WebApi.AreaServer 這個目錄下,切記一定要進入到項目根目錄,不然配置文件就生成到別的地方去了)
運行一下代碼 安裝SkyAPM.Dotnet.CLI:
dotnet tool install -g SkyAPM.DotNet.CLI
然使用skyapm生成配置文件,命令如下:
dotnet skyapm config sample_app 192.168.0.1:11800
其中192.168.0.1:11800是上面我們安裝完成的skywalking服務端里配置的,將這個ip改成上面伺服器的ip即可
執行完上面的命令後,項目下會生成一個名為skyapm.json的文件,其中的代碼如下:

{ "SkyWalking": { "ServiceName": "sample_app", "Namespace": "", "HeaderVersions": [ "sw6" ], "Sampling": { "SamplePer3Secs": -1, "Percentage": -1.0 }, "Logging": { "Level": "Information", "FilePath": "logs\\skyapm-{Date}.log" }, "Transport": { "Interval": 3000, "ProtocolVersion": "v6", "QueueSize": 30000, "BatchSize": 3000, "gRPC": { "Servers": "192.168.0.1:11800", "Timeout": 10000, "ConnectTimeout": 10000, "ReportTimeout": 600000 } } } }View Code
skyapm.json文件不一定要使用命令生成,也可自己在項目中創建一個名為skyapm.json的文件,然後將上面代碼複製進去,修改其ip即可
在vs中右鍵單擊skyapm.json,選擇屬性——》複製到輸出目錄——》如果較新則複製
然後選擇控制台運行項目即可
運行代碼後,控制台內每隔幾秒就會有以下信息輸出
證明skywalking探針已經成功,接下來請求一下你的介面,然後進入skywalking的ui中看看你的成果吧!
