默认配置文件
$ cat 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']
scrape_configs 配置段中，通过静态配置方式指定从localhost:9090/metrics拉取指标信息，其中9090是prometheus server启动后监听的端口
通过访问 http://localhost:9090/metrics，可以观察prometheus自身提供的各种监控指标
通过界面访问
将Promethues配置成系统服务，随系统启动
编辑启动文件
$ cat > /etc/systemd/system/prometheus.service<< EOF

Promethues提供了很多的命令行配置选项，可通过./prometheus -h进行查看
通过systemctl启动prometheus
$ systemctl daemon-reload
$ systemctl start prometheus
$ systemctl enable prometheus
前提是服务器上已经装上了docker环境
下载镜像
$ docker pull prom/prometheus:v2.16.0
启动镜像
$ docker run -p 9090:9090 prom/prometheus:v2.16.0
通过挂载方式将配置文件挂载到容器内来自定义配置项
docker run -p 9090:9090 -v /tmp/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus:v2.16.0
或者将配置目录直接挂载进去
docker run -p 9090:9090 -v /path/to/config:/etc/prometheus prom/prometheus:v2.16.0
如果监控目标以及rule等信息都稳定下来，可以基于prometheus的镜像，将配置文件等信息追加到容器中,Dockerfile如下
FROM prom/prometheus:v2.16.0
ADD prometheus.yml /etc/prometheus/
