1.思路

Tongweb嵌入式最终是把依赖打入到java应用（也就是jar包里），然后启动jar包进行测试，所以我们需要考虑的是，启动jar包的时候，怎么获取到监控数据。

根据Prometheus+Grafana 监控Tongweb7来看，监控数据是通过jmx_prometheus_javaagent-0.19.0.jar和config.yaml这两个关键文件来获取的，但是这里用的是企业版的部署方式（类似于部署了tomcat然后在tomcat的webapps里部署应用的方式一样）。

所以我们可以通过启动参数的形式，启动应用jar包的同时，使用jmx_prometheus_javaagent来配置JMX指标的暴露端口为38061，并指定配置文件为config.yaml，也就是这样的指令来启动jar包，从而方便Prometheus拉取监控数据：

java -javaagent:jmx_prometheus_javaagent-0.19.0.jar=39081:config.yaml -jar spring-boot-accesslog-2.x-0.0.1.jar

在这里插入图片描述

其中config.yaml是相关配置文件，jmx_prometheus_javaagent-0.19.0.jar是拉取监控数据用的jar包，spring-boot-accesslog-2.x-0.0.1.jar是测试用的jar包（已经导入tongweb嵌入式的依赖并打包了），39081是绑定的监听端口（可以自己设置一个没有占用的端口）。

之后访问服务器ip:39081/metrics,如下图所示就说明获取成功了：

获取成功之后，再部署prometheus和grafana，修改对应配置，配置grafana的数据源和仪表盘即可。

2.部署准备

本次参考：Prometheus监控Tongweb容器

1.使用虚拟机ip：192.168.10.51（tongweb），192.168.10.52（Prometheus），192.168.10.8(Grafana ),其中51服务器确保9060，39081端口没有被占用,52服务器确保9090端口没有被占用，8服务器确保3000端口没有被占用，三台虚拟机均关闭防火墙。

2.使用的jar包：jmx_prometheus_javaagent-0.19.0.jar:jmx_prometheus_javaagent-0.19.0.jar下载链接

在这里插入图片描述

3.使用的jdk环境：jdk1.8(需配置jdk环境变量)

在这里插入图片描述
4.下载Grafana使用的仪表盘json文件：
TongWeb 面板，使用JMX Exporter采集数据

也可以新建一个json文件，复制粘贴以下内容：

      "description": "tomcat_requestcount_total是Tomcat服务器的一个请求计数器，它记录了所有已处理的请求总数。 在Tomcat服务器中，每个客户端请求都会被处理为一个请求，在处理请求期间，服务器会从连接中读取数据、解析数据、执行应用逻辑，并返回响应。每当Tomcat服务器成功处理一个请求时，其tomcat_requestcount_total指标就会相应地增加。监控和分析该指标可以帮助管理员和开发人员更好地了解Tomcat服务器的整体负载情况和活动水平，对于性能优化和故障排除都具有一定的价值。此外，该指标也可以通过与其他指标如tomcat_bytesreceived_total和tomcat_bytessent_total等结合使用，来监测网络流量和请求响应时间等性能指标，以进一步优化Tomcat服务器的配置和性能。",

也可以自行下载跟tomcat8.5相关的json文件仪表盘，这个自行百度。

5.tw7的安装包和授权，其中tw7使用的安装包为TongWeb7.0.4.9_M3_Enterprise_Linux.tar.gz。

3.应用jar包修改配置和导入tw嵌入式的依赖（参考）

本次示范用的是TongWeb7.0.E.6_P5下的spring-boot-accesslog-2.x：在这里插入图片描述
请在本地开发环境配置好mavernhome，配置教程如下：
maven环境变量配置（超详细！）

在这里插入图片描述
在这里插入图片描述
配置后，window下，使用 installAll-{n} 脚本，解压 TongWeb 嵌入式版资源包，将 lib 目录中的 jar 包安装到本地 maven 仓库。

在这里插入图片描述
配置以下依赖到pom文件里（这一步可以参考手册：TongWeb V7.0 嵌入式版_JavaEE标准容器用户指南，记得去掉tomcat的依赖）：

   <!--TongWeb 嵌入式版提供的与springboot集成的starter。 -->
        <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-websocket</artifactId>
        </dependency>
        <dependency>
          <groupId>com.tongweb.springboot</groupId>
            <artifactId>tongweb-spring-boot-websocket-2.x</artifactId>
           <version>7.0.E.6_P5</version>
        </dependency>
        <dependency>
           <groupId>com.tongweb.springboot</groupId>
           <artifactId>tongweb-spring-boot-starter-2.x</artifactId>
           <version>7.0.E.6_P5</version>
        </dependency>
        <dependency>
           <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
           <exclusions>
          <exclusion>
           <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
          </exclusion>
       </exclusions>
        </dependency>
        <!-- jsp支持-->
        <dependency>
            <groupId>com.tongweb</groupId>
            <artifactId>tongweb-jsp</artifactId>
            <version>7.0.E.6_P5</version>
        </dependency>

刷新maven，然后看看tongweb的依赖是否已经导入到项目里
在这里插入图片描述
授权文件放入到resource目录下，propeities配置文件配置：

server.tongweb.license.path=classpath:license.dat

在这里插入图片描述
如果用的不是propeities文件，配置参考如下：

server:
  tongweb:
    license:
      path: classpath:license.dat

之后进行打包，打包看看有没有报错，有的话看看报错信息，如果是依赖冲突，可以使用mavenhelp，参考：
maven解决包冲突简单方式(插件maven helper | maven指令)
在这里插入图片描述

在这里插入图片描述

在这里插入图片描述
打包后最好在本地跑一次看看有没有问题，没有的话和已经下载好的jmx.xxxjar放入到服务器，下面是我放入服务器的目录截图：

在这里插入图片描述
自己新建一个config.yaml,以下是配置内容：

wercaseOutputLabelNames: true
lowercaseOutputName: true
whitelistObjectNames: ["java.lang:type=OperatingSystem", "TONGWEB:*","config:*"]
blacklistObjectNames: []
rules:
  - pattern: ".*"

执行指令启动应用

java -javaagent:jmx_prometheus_javaagent-0.19.0.jar=39081:config.yaml -jar spring-boot-accesslog-2.x-0.0.1.jar

访问服务器ip:39081/metrics

在这里插入图片描述
这一部分在第一节已经有详细说明。

4.Prometheus部署

参考：一篇文章搞定Prometheus普罗米修斯监控系统的部署

5.Prometheus配置

配置prometheus.yml：

在这里插入图片描述

在这里插入图片描述

配置参考（注意缩进，192.168.10.51和39081分别对应的是tongweb这边的端口和ip）：


    static_configs:
      - targets: ["localhost:9090"]
        - job_name: tongweb
    static_configs:
      - targets: ['192.168.10.51:39081']
        labels:
          instance: 192.168.10.51

下面是我本地的配置文件，自行删除不需要的部分：

global:
  scrape_interval: 15s        # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s    # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

alerting:
  alertmanagers:
    - static_configs:
        - targets:
          # - alertmanager:9093

rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

scrape_configs:
  - job_name: "prometheus"
    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
    static_configs:
      - targets: ["localhost:9090"]

  - job_name: 'Prometheus19'
    metrics_path: /metrics
    static_configs:
      - targets:
        - rds
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: 192.168.10.19:9098

  - job_name: 'Prometheus20'
    metrics_path: /metrics
    static_configs:
      - targets:
        - rds
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: 192.168.10.20:9098

  - job_name: "tongweb"
    static_configs:
      - targets: ['192.168.10.51:39081']
        labels:
          instance: 192.168.10.51

修改完启动Prometheus

cd /usr/local/promethues/

./prometheus --config.file="/usr/local/promethues/prometheus.yml" &

ps ef |grep promethues

访问服务器ip:9090/targets?search=,点击status，target，就可以看到我们配置的信息：
在这里插入图片描述

6.安装和配置Grafana

Grafana下载地址

在这里插入图片描述
上图的话，安装后用 systemctl start grafana-server 启动，会方便一些。

或者用这个也行，这个的话后面启动要用脚本启动（本文使用这种方式）。
在这里插入图片描述
解压一下安装包

tar -vxf grafana-enterprise-10.3.1.linux-amd64.tar.gz

启动：
cd 到安装目录bin目录，执行./grafana-server,然后访问服务器ip:3000

注意：默认账号密码为：
账号：admin
密码：admin



如果你想卸载，可以关闭服务（直接pkill grafana-server也行），直接删除安装目录，然后删除对应配置

```xml
sudo rm -rf /var/lib/grafana
sudo rm -rf /var/log/grafana
sudo rm -rf /etc/grafana
sudo rm -rf /etc/grafana/grafana.ini
sudo rm -rf  /var/lib/grafana/grafana.db

在这里插入图片描述

通常情况下，Grafana 服务的配置文件位于 /etc/grafana/grafana.ini，日志通常存储在 /var/log/grafana，而数据库默认位于 /var/lib/grafana/grafana.db。您可能需要查看这些文件以进行故障排查或者进行配置更改。记得在修改配置文件之后重启 Grafana 服务使更改生效。

Grafana只用于展示数据，需要配置Prometheus数据源。

在这里插入图片描述

在这里插入图片描述
写你的prometheus的url，带上端口号9090：
在这里插入图片描述

点击下方的sava&test，有下图的提示说明成功：
在这里插入图片描述
然后回到home，找到Create your first dashboard：
在这里插入图片描述
点击import a dashboard：
在这里插入图片描述
上传之前下载的json文件在这里插入图片描述
上传后选择一下prometheus：

然后点击import，仪表盘就出现了：
