简介
Prometheus
Prometheus,是一个开源的系统监控和告警的工具包,其采用Pull方式采集时间序列的度量数据(也支持push方式),通过Http协议传输。它的工作方式是被监控的服务需要公开一个Prometheus端点,这端点是一个HTTP接口,该接口公开了度量的列表和当前的值,然后Prometheus应用从此接口定时拉取数据,一般可以存放在时序数据库中,然后通过可视化的Dashboard(e.g.Grafana)进行数据展示。
支持的prometheus metrics
Counter,Gauge,Histogram,Summary,untyped等等。需要注意的是counter只能增不能减,适用于服务请求量,用户访问数等统计,但是如果需要统计有增有减的指标需要用Gauge。
exporter
支持的 exporter 很多,可以方便的监控很多应用,同时也可以自定义开发非官方提供的exporter。
grafana
grafana,是一个开源的dashboard展示工具,可以支持很多主流数据源,包括时序性的和非时序性的。其提供的展示配置以及可扩展性能满足绝大部分时间序列数据展示需求,是一个比较优秀的工具。
支持的数据源
prometheus,inflexdb,elasticsearch,mysql,postgreSQL,openTSDB等,更多数据源:https://grafana.com/grafana/plugins/?type=datasource

Prometheus安装
下载地址:https://prometheus.io/download/

修改配置:
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'.
#暴露路径
metrics_path: /actuator/prometheus
static_configs:
#SpringBoot的ip和端口号
- targets: ['localhost:8080']
