prometheus + grafana对 springboot 项目进行监控
1.prometheus接入springboot
prometheus安装后,在安装目录有一个默认的配置文件prometheus.yml
# 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:
# - alertmanager: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: ["localhost:9090"]
默认配置了一个job_name,监控prometheus本身。需要增加一个监控springboot项目
- job_name: "custom_spring_boot"
metrics_path: '/actuator/prometheus'
static_configs:
- targets: ["localhost:9595"]

-
metrics_path 默认采集metrics的路径是 /metrics
;需要改成/actuator/prometheus
-
scheme 默认是http;如果是https需要自定义配置 -
targets 获取metrics的地址和端口列表
2.访问prometheus
http://127.0.0.1:9090/

出现自定义需要监控的springboot端点列表

在首页,可以查询各种不同的指标
比如查询custom_http_request_time_seconds_count
指标

3.grafana接入prometheus
访问
http://127.0.0.1:3000/
配置数据源

添加一个数据

选择prometheus

设置名称和prometheus服务地址


4.配置仪表盘

点击Add a new panel
;新建一个Panel

平均时间查询
sum by(api) (rate(custom_http_request_time_seconds_count{job="custom_spring_boot", api="/order"}[5m]))

保存,最终显示
