prometheus 监控jvm（上）

1.setup prom

https://prometheus.io/

https://github.com/prometheus/prometheus/releases/tag/v1.6.2

nohup ./prometheus --config.file=prometheus.yml &

WEB页面访问http://localhost:9090/ ，可以看到Prometheus的graph页面。

 

2 热加载配置

curl -X POST http://localhost:9090/-/reload

 

3 node exporter / mysql exporter client

https://prometheus.io/download/

https://github.com/prometheus

 mysql 还需要编辑：.my.cnf

[client]
host=127.0.0.1
user=fast
password=1qaz@WSX

 nohup ./node_exporter &

nohup ./mysqld_exporter --config.my-cnf=".my.cnf" &

通过localhost:9104，9100 就可以看到exporter导出的数据了：

 

4 server  vi prometheus.yml

 37   - job_name: 'linux'
 38     static_configs:
 39     - targets: ['192.168.57.67:9100']
 40       labels:
 41          instance: db1

 

 31   - job_name: 'mysql'
 32     static_configs:
 33     - targets: ['192.168.57.67:9104']
 34       labels:
 35          instance: db1

 

重启prometheus，点击导航栏中的status->targets可以看到，mysql的exporter已经集成进来了。
