Java编写监控指标并集成Prometheus、Grafana

标签：opt Java log prometheus module Grafana Prometheus pushgateway SpringBoot

一、Pushgateway

1、上传pushgateway-1.4.3.linux-amd64.tar.gz至/opt/soft/

　　下载地址：https://github.com/prometheus/pushgateway/releases/download/v1.4.3/pushgateway-1.4.3.linux-amd64.tar.gz

2、解压至/opt/module/，并修改目录名称

tar -zxvf /opt/soft/pushgateway-1.4.3.linux-amd64.tar.gz -C /opt/module/
mv /opt/module/pushgateway-1.4.3.linux-amd64/ /opt/module/pushgateway-1.4.3

3、启动pushgateway

nohup /opt/module/pushgateway-1.4.3/pushgateway --web.listen-address 127.0.0.1:9091 >/opt/module/pushgateway-1.4.3/pushgateway.log 2>&1 &

4、查看Web页面

　　http://127.0.0.1:9091

5、设置开机自启

vi /etc/systemd/system/pushgateway.service

　　添加如下内容：

[Unit]
Description=logging pushgateway service

[Service]
Type=simple
User=root
Group=root
ExecStart=/opt/module/pushgateway-1.4.3/pushgateway --web.listen-address 127.0.0.1:9091

Restart=on-failure

[Install]
WantedBy=multi-user.target

6、赋予权限

chmod 777 /etc/systemd/system/pushgateway.service

7、刷新文件

systemctl daemon-reload
systemctl start pushgateway
systemctl enable pushgateway

8、停止

ps -ef | grep pushgateway | grep -v grep | awk '{print $2}' | xargs kill

9、编写重启脚本

vi /opt/module/pushgateway-1.4.3/restart.sh

　　添加如下内容：

#!/bin/bash
process=`ps -ef | grep /opt/module/pushgateway-1.4.3/pushgateway | grep -v grep | awk '{print $2}'`;
echo "process=$process"
if [ "$process" == "" ]; then
echo "$(date "+%Y-%m-%d %H:%M:%S")：pushgateway已经停止";
else
kill -9 $process
echo "$(date "+%Y-%m-%d %H:%M:%S")：pushgateway已被kill";
fi

sleep 3

echo "启动pushgateway"
nohup /opt/module/pushgateway-1.4.3/pushgateway --web.listen-address 127.0.0.1:9091 >/opt/module/pushgateway-1.4.3/pushgateway.log 2>&1 &

10、赋予可执行权限

chmod +x /opt/module/pushgateway-1.4.3/restart.sh

11、定时执行（目的是pushgateway使用时间过久会出现卡死现象，故设置1小时重启一次）

vi /etc/crontab

　　添加如下内容：

36 */1 * * * root cd /opt/module/pushgateway-1.4.3 && sh restart.sh

二、prometheus server

1、上传prometheus-2.38.0.linux-amd64.tar.gz至/opt/soft/

　　下载地址：https://github.com/prometheus/prometheus/releases/download/v2.38.0/prometheus-2.38.0.linux-amd64.tar.gz

2、解压至/opt/module/，并修改目录名称

tar -zxvf /opt/soft/prometheus-2.38.0.linux-amd64.tar.gz -C /opt/module/
mv /opt/module/prometheus-2.38.0.linux-amd64/ /opt/module/prometheus-2.38.0

3、修改配置文件

vi /opt/module/prometheus-2.38.0/prometheus.yml

　　修改如下内容：

# my global config
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).

# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets: ["127.0.0.1:9093"] 

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'
    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
    static_configs:
    - targets: ['127.0.0.1:9090']
    
  # 添加 PushGateway 监控配置
  - job_name: 'pushgateway'
    static_configs:
    - targets: ['127.0.0.1:9091']
      labels:
        instance: pushgateway

4、启动prometheus

nohup /opt/module/prometheus-2.38.0/prometheus --config.file=/opt/module/prometheus-2.38.0/prometheus.yml --web.enable-admin-api > /opt/module/prometheus-2.38.0/prometheus.log 2>&1 &

5、使用Systemctl管理Prometheus

vi /etc/systemd/system/prometheus.service

　　添加如下内容：

[Unit]
Description=logging prometheus service
Documentation=https://prometheus.io

[Service]
Type=simple
User=root
Group=root
ExecStart=/opt/module/prometheus-2.38.0/prometheus --config.file=/opt/module/prometheus-2.38.0/prometheus.yml --web.enable-admin-api

Restart=on-failure

[Install]
WantedBy=multi-user.target

6、赋予权限

chmod 777 /etc/systemd/system/prometheus.service

7、刷新文件并设置自启

systemctl daemon-reload
systemctl start prometheus
systemctl enable prometheus

8、停止

systemctl stop prometheus
ps -ef |grep -v grep | grep /opt/module/prometheus-2.38.0/prometheus | awk '{print $2}' | xargs kill

9、查看

ps -ef |grep -v grep | grep /opt/module/prometheus-2.38.0/prometheus

10、查看Web页面

　　http://127.0.0.1:9090

三、监控Zookeeper（已停用）

1、修改配置文件

vi /opt/module/prometheus-2.38.0/prometheus.yml

# 添加 zookeeper 监控配置
- job_name: 'zookeeper'
static_configs:
- targets: ['127.0.0.1:7000','127.0.0.1:7000','127.0.0.1:7000']
labels:
instance: zookeeper

2、重启prometheus

systemctl restart prometheus

四、监控集群

1、Idea新建Maven工程

2、修改pom文件

5、添加 application.properties 文件

6、创建SpringBoot启动主类

com.yuange.promethues.YuangePromethuesApplication

package com.yuange.promethues;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @作者：袁工
 * @时间：2023/2/22 14:31
 */
@SpringBootApplication
public class YuangePromethuesApplication {

    public static void main(String[] args) {
        SpringApplication.run(YuangePromethuesApplication.class,args);
    }
    
}

7、后续代码介绍

　　代码过多就不一一说明，码云地址为：https://gitee.com/LzMingYueShanPao/prometheus.git

　　yuange-prometheus模块是一个SpringBoot项目，项目启动后的端口为8999，可在application.properties中配置。

　　此外，controller中的ClusterMetricController.java，编写了接口：/metrics/prdClusterMetric 表示大数据集群监控接口

　　监控的指标数据包括：内存/核心数的使用百分比，Yarn资源的相关指标，NameNode/HiveServer2的HeapMemoryUsage指标，DataNode的心跳数据，Telnet方式监控的IP+端口存活监控等

8、在Idea中使用Maven打包后将Jar包上传至/opt/module/prometheus-2.38.0/java目录

9、编写启停脚本restart.sh

vim /opt/module/prometheus-2.38.0/java/restart.sh

#!/bin/bash

  [ $LOG_LEVEL -le 1  ] && echo -e "\033[32m"  ${content}  "\033[0m"
}
# 信息日志
function log_info(){
  content="[INFO] $(date '+%Y-%m-%d %H:%M:%S') $@"
  [ $LOG_LEVEL -le 2  ] && echo -e "\033[32m"  ${content} "\033[0m"
}
# 警告日志
function log_warn(){
  content="[WARN] $(date '+%Y-%m-%d %H:%M:%S') $@"

}
# 一直都会打印的日志
function log_always(){
   content="[ALWAYS] $(date '+%Y-%m-%d %H:%M:%S') $@"
   [ $LOG_LEVEL -le 5  ] && echo -e  "\033[32m" ${content} "\033[0m"
}

10、赋予权限

chmod +x /opt/module/prometheus-2.38.0/java/restart.sh

11、创建日志文件

mkdir -p /opt/module/prometheus-2.38.0/java/logs/meiyijia-promethues-1
touch /opt/module/prometheus-2.38.0/java/logs/meiyijia-promethues-1/debug.log

12、启动Java程序

cd /opt/module/prometheus-2.38.0/java/
sh restart.sh meiyijia-promethues-1.0-SNAPSHOT.jar start

　　查看接口地址：http://127.0.0.1:8999/metrics/prdClusterMetric

13、修改promethues配置

vi /opt/module/prometheus-2.38.0/prometheus.yml

添加如下内容：

# 添加自定义集群监控配置
- job_name: 'prdClusterMetric'
metrics_path: '/metrics/prdClusterMetric'
static_configs:
- targets: ['127.0.0.1:8999']
labels:
instance: prdClusterMetric

14、重启promethues

systemctl restart prometheus

15、查看状态

systemctl status prometheus

　　http://127.0.0.1:9090/targets?search=

五、安装和配置Grafana

1、下载安装包

wget https://repo.huaweicloud.com/grafana/7.4.3/grafana-7.4.3-1.x86_64.rpm -P /opt/soft

2、依赖安装

yum install -y /sbin/service fontconfig freetype urw-fonts

3、安装

rpm -ivh /opt/soft/grafana-7.4.3-1.x86_64.rpm

4、刷新

systemctl daemon-reload

5、启动

systemctl start grafana-server.service

6、开机自启

systemctl enable grafana-server.service

7、查看状态

systemctl status grafana-server.service

8、配置域名访问

vim /usr/share/grafana/conf/defaults.ini

　　在[server]下添加如下内容：

[server]
domain = grafana-yuange.yuange.com.cn

　　并修改如下内容：

root_url = %(protocol)s://%(domain)s:%(http_port)s/

　　为：

root_url = %(protocol)s://%(domain)s/

9、访问Web（账号：admin 密码：admin）

http://127.0.0.1:3000/login

https://grafana-yuange.yuange.com.cn/

10、添加Promethues数据源

11、Grafana配置相应指标监控

（1）对于IP端口监控示例

sum(ACTIVESTATE{instance="prdClusterMetric",name="NameNode",type="prdActive"})

（2）对于NumStaleDataNodes指标（DataNode节点进入State状态监控）

ACTIVESTATE{instance="prdClusterMetric",name="NumStaleDataNodes"}

（3）对于yarn_unhealthynodes指标（Yarn不良节点数监控）

yarn_unhealthynodes{instance="prdClusterMetric"}

（4）对于HeapMemoryUsage、NonHeapMemoryUsage指标（堆内存监控）

abs(delta(ACTIVESTATE{instance="prdClusterMetric",name="HeapMemoryUsage",ip="127.0.0.1",port="9870"}[10m]))

abs(delta(ACTIVESTATE{instance="prdClusterMetric",name="NonHeapMemoryUsage",ip="127.0.0.1",port="9870"}[10m]))

（5）对于HeartbeatsTotalNumOps指标（DataNode节点心跳监控）

increase(ACTIVESTATE{instance="prdClusterMetric",name="HeartbeatsTotalNumOps",ip="127.0.0.1"}[1m])

（6）对于yarn_reservedmb指标（yarn申请中的内存）

yarn_reservedmb{instance="prdClusterMetric"}

（7）对于yarn_reservedvirtualcores指标（yarn申请中的核心）

yarn_reservedvirtualcores{instance="prdClusterMetric"}

（8）对于yarn_activenodes指标（集群运行中的节点数）

yarn_activenodes{instance="prdClusterMetric"}

（9）对于yarn_allocatedmb指标（集群已使用的总内存）

yarn_allocatedmb{instance="prdClusterMetric"}

（10）对于memory_percentage指标（集群中的各队列中的内存使用百分率）

memory_percentage{instance="prdClusterMetric"}

（11）对于vcores_percentage指标（集群中的各队列中的CPU核数使用百分率）

vcores_percentage{instance="prdClusterMetric"}

12、监控告警（集成飞书、企业微信）模版

13、告警内容模版

报！监控到生产集群中NameNode挂掉超过5分钟！请主公定夺！
<#list root as c>
指标：${c.metric}  告警值：${c.value}
</#list>
