下载搭建node_exporter(采集机器的负载情况)

tar zxvf node_exporter-1.3.1.linux-386.tar.gz

创建启动命令

cd node_exporter-1.3.1.linux-386/
touch start_node_exporter.sh
vim start_node_exporter.sh
nohup ./node_exporter> nodeout.file 2>&1 &

授权

chmod +x start_node_exporter.sh

验证

http://:9100/

mtail下载搭建(应用日志监控)

tar zxvf mtail_3.0.0-rc47_Linux_x86_64.tar.gz

此版本是可执行二进制文件，将其重命名为mtail，移动至/usr/local/sbin下即可使用

mv mtail /usr/local/sbin

验证

mtail -version

创建 配置文件路径

mkdir mtail_files
cd mtail_files/
touch qianlan-server.mtail
vim qianlan-server.mtail

counter login_success
/登录成功/ {
login_success++
}

赋权

chmod +x *

启动命令脚本

touch start_mtail.sh
vim start_mtail.sh
nohup mtail -port 3903 -logtostderr -progs /opt/mtail_files/qianlan-server.mtail -logs '/home/kuma/logs/prod/qianlan-/-127.0.0.1.log' 2>&1 &

验证

http://:3903/

查看进程是否启动成功

ps -ef | grep mtail

下载安装prometheus

tar zxvf prometheus-2.32.0-rc.0.linux-amd64.tar.gz

修改配置文件prometheus.yml添加node_exporter和matail 的采集路径

cd prometheus-2.32.0-rc.0.linux-amd64/
vim prometheus.yml

scrape_configs:

The job name is added as a label job=<job_name> to any timeseries scraped from this config.

  • job_name: 'prometheus'
    static_configs:

    • targets: ['localhost:9090']

  • job_name: 'node_exporter'
    static_configs:

    • targets: [':9100']

  • job_name: '73_node_exporter'
    static_configs:

    • targets: [':9100']

  • job_name: 'mtail'
    static_configs:

    • targets: [':3903']

  • job_name: 'grafana'
    static_configs:

    • targets: ['localhost:3000']

以下内容为jmx-exporter应用配置

  • job_name: 'student-jmx-exporter'
    scrape_interval: 10s
    metrics_path: '/metrics'
    static_configs:

    • targets: [ ':1000' ]
      labels:
      appname: 'student-jmx-exporter'

  • job_name: 'student-jmx-exporter'
    static_configs:
    - targets: [':1000']

  • job_name: 'mng-jmx-exporter'
    static_configs:
    - targets: [':1001']

touch start_promtool.sh

vim start_promtool.sh
nohup ./prometheus --config.file=prometheus.yml > prometheus.file 2>&1 &

http://:9090/graph

ps -ef |grep prometheus

grafana(图像展示)

wget https://dl.grafana.com/enterprise/release/grafana-enterprise-8.3.1.linux-amd64.tar.gz
tar -zxvf grafana-enterprise-8.3.1.linux-amd64.tar.gz
cd grafana-8.3.1/
touch start_grafana.sh
vim start_grafana.sh
nohup ./bin/grafana-server start > grafana.file 2>&1 &
chmod +x start_grafana.sh
ps -ef |grep grafana

http://:3000

配置数据源 prometheus

grafana添加 node_exporter 的Dashboard
导入id 8919 的桌面

jmx_exporter + Prometheus 监控jmx
简单说一下启动，官方给出的 jmx_exporter启动命令是：

java -javaagent:./jmx_prometheus_javaagent-0.13.0.jar=8080:config.yaml -jar yourJar.jar

wget https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.12.0/jmx_prometheus_javaagent-0.12.0.jar

进入java服务中创建配置文件

cd /opt/qianlan-student/config
touch jmx_exporter.yml
chmod +x jmx_exporter.yml
vim jmx_exporter.yml

jar 的方式启动

java -javaagent:/opt/lib/jmx_exporter/jmx_prometheus_javaagent-0.12.0.jar=1000:/opt/lib/jmx_exporter/jmx_exporter.yml -Dspring.config.location=def.properties -Dserver.port=1000 -jar

nohup ${JAVA_EXE} -Denv=${PROJECT_ENV} -Dapp.id=${APP_ID} -javaagent:/opt/lib/jmx_exporter/jmx_prometheus_javaagent-0.12.0.jar=1000:/opt/lib/jmx_exporter/jmx_exporter.yml -Dspring.config.location=def.properties -Dserver.port=10001
-jar ${PROJECT_HOME}/${PROJECT_JAR}
--spring.config.location=${PROJECT_CONFIG}
--logging.config=${PROJECT_CONFIG}/logback-spring.xml > /dev/null 2>&1 &

进入prometheus 检查配置是否生效

使用id为8563进行 grafana 配置。
修改 job 和 prometheus保持一致
