二 nacos暴露metric数据
2.1 修改application.properties文件
~# grep management.endpoints.web.exposure.include /usr/local/nacos/conf/application.properties
#management.endpoints.web.exposure.include=*
~# sed -i 's@#management.endpoints.web.exposure.include@management.endpoints.web.exposure.include@g' /usr/local/nacos/conf/application.properties
~# grep management.endpoints.web.exposure.include /usr/local/nacos/conf/application.properties
management.endpoints.web.exposure.include=*2.2 重启nacos服务
~# systemctl restart nacos2.3 验证nacos web界面
http://192.168.174.103:8848/nacos/actuator/prometheus
三 Prometheus监控nacos
3.1 修改Prometheus.yml文件
~# cat /usr/local/prometheus/prometheus.yml
- job_name: "nacos"
metrics_path: '/nacos/actuator/prometheus'
static_configs:
- targets:
- "192.168.174.103:8848"
- "192.168.174.104:8848"
- "192.168.174.105:8848"3.2 重启Prometheus服务
~# systemctl restart prometheus3.3 验证Prometheus web界面
3.4 验证Prometheus 数据
