prometheus

从零开始搭建Prometheus自动监控报警系统 - 雪山飞猪 - 博客园 (cnblogs.com)

--挂在目录设置，以及配置文件

mkdir -p /home/chenqionghe/promethues
mkdir -p /home/chenqionghe/promethues/server
mkdir -p /home/chenqionghe/promethues/client
touch /home/chenqionghe/promethues/server/rules.yml
chmod 777 /home/chenqionghe/promethues/server/rules.yml

mkdir -p /home/chenqionghe/test/prometheus
touch -p /home/chenqionghe/test/prometheus/prometheus.yml
chmod 777 /home/chenqionghe/test/prometheus/prometheus.yml

prometheus.yml对应的内容
global:
scrape_interval: 15s
external_labels:
monitor: 'codelab-monitor'
scrape_configs:
- job_name: 'prometheus'
scrape_interval: 5s
static_configs:
- targets: ['localhost:9090']

--启动容器
docker rm -f prometheus
docker run --name=prometheus -d
-p 9090:9090
-v /home/chenqionghe/promethues/server/prometheus.yml:/etc/prometheus/prometheus.yml
-v /home/chenqionghe/promethues/server/rules.yml:/etc/prometheus/rules.yml
prom/prometheus
--config.file=/etc/prometheus/prometheus.yml
--web.enable-lifecycle

热加载配置文件
调用指令是curl -X POST http://localhost:9090/-/reload

我们配置了9090端口，默认prometheus会抓取自己的/metrics接口
访问http://10.211.55.25:9090/metrics

查看监控节点
http://192.168.226.131:9091/targets

访问http://10.211.55.25:9090

配置influxdb作为存储
remote_write:
- url: "http://127.0.0.1:8086/api/v1/prom/write?db=prometheusdb"
basic_auth:
username: admin
password: admin
remote_read:
- url: "http://127.0.0.1:8086/api/v1/prom/read?db=prometheusdb"
basic_auth:
username: admin
password: admin

--安装pushgateway
mkdir -p /home/chenqionghe/promethues/pushgateway
cd !$
docker run -d -p 9092:9091 --name pushgateway prom/pushgateway

访问 http://192.168.226.131:9092/

配置监控节点
- job_name: pushgateway
scrape_interval: 30s
honor_labels: true
static_configs:
- targets: ['192.168.1.100:9091']
labels:
instance: pushgateway

安装Grafana
docker run -d -p 3000:3000 --name grafana grafana/grafana

--监控物理机程序客户端node-exporter
docker run -d
--name=node-exporter
-p 9100:9100
prom/node-exporter

--修改配置文件， 加入监控节点

--安装docker监听
docker run -d
-v=/:/rootfs:ro
-v=/var/run:/var/run:ro
-v=/sys:/sys:ro
-v=/var/lib/docker/:/var/lib/docker:ro
-v=/dev/disk/:/dev/disk:ro
-p=8081:8080
--name=cadvisor
--restart=always
google/cadvisor

--配置监控文件
- job_name: 'docker'
static_configs:
- targets: ['192.168.31.138:8080']
labels:
instance: docker测试
