# 背景
## 系统监控
- SkyWalking
- Zabbix
## 业务监控(APM)
- Pinpoint
- Prometheus
# Prometheus
## 安装启动
### Linux安装
```shell
# 下载
wget https://github.com/prometheus/prometheus/releases/download/v2.35.0-rc1/prometheus-2.35.0-rc1.linux-amd64.tar.gz
# 解压
tar -zxvf prometheus-2.35.0-rc1.linux-amd64.tar.gz
mv prometheus-2.35.0-rc1.linux-amd64 prometheus
# 启动
./prometheus --config.file=./prometheus.yml --web.enable-lifecycle
# --config.file=./prometheus.yml 指定配置
# --web.enable-lifecycle这个参数的主要目的是为了运行时重载配置
```
### Docker安装
```shell
# 启动prometheus
docker run -d --name=prometheus -p 9090:9090 \
-v /home/soft/monitor/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml \
-v /etc/localtime:/etc/localtime:ro \
prom/prometheus
```
### 测试
http://localhost:9090/targets
## Node Exporter
据说最好安装在linux上。
### 下载安装
```shell
# 启动node_exporter
nohup ./node_exporter --web.listen-address 172.16.1.167:8081 &
# 访问地址http://172.16.1.167:8081/metrics
```
### 配置方式
```yaml
- job_name: node
static_configs:
- targets: ['localhost:9100']
```
### 监控模板
https://grafana.com/grafana/dashboards/1860
https://grafana.com/grafana/dashboards/9276
## cAdvisor
### Docker安装
Docker部署cAdvisor用于监控docker的容器的运行指标。
```shell
# 启动cAdvisor
docker run -d \
volume=/:/rootfs:ro \
volume=/var/run:/var/run:ro \
volume=/sys:/sys:ro \
volume=/var/lib/docker/:/var/lib/docker:ro \
volume=/dev/disk/:/dev/disk:ro \
-v /etc/localtime:/etc/localtime:ro \
publish=8080:8080 \
detach=true \
name=cadvisor \
google/cadvisor:latest
```
访问方法192.168.200.137:8080 可以看到cAdvisor是否启动
访问http://192.168.200.137:8080/metrics有数据就说明cAdvisor是启动好了的
### 加入配置
```yaml
- job_name: 'docker'
static_configs:
- targets: ['192.168.200.137:8080']
labels:
instance: docker
```
### 监控模板
https://grafana.com/grafana/dashboards/193
## spring-boot-admin
监控springboot。
### 依赖包
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<!--prometheus监控 https://prometheus.io/docs/introduction/overview/-->
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-prometheus</artifactId>
</dependency>
```
### 配置信息
```yaml
scrape_configs:
- job_name: 'demo-server-monitor'
metrics_path: '/actuator/prometheus'
scrape_interval: 2s
static_configs:
- targets: ['localhost:8080']
```

# Grafana
## 安装启动
### Docker安装
```shell
# 启动grafana
docker run -d -p 3000:3000 --name=grafana \
-v /home/soft/monitor/grafana/Grafana-storage:/var/lib/Grafana \
-v /etc/localtime:/etc/localtime:ro \
grafana/grafana
```
## 使用方式
- 第一步添加数据源prometheus
- 第二步导入或创建Dashboard
# Sentry
# SkyWalking
