Grafana+Prometheus系统监控MySQL

Grafana+Prometheus 不单单是可以监控MySQL，还可以监控服务器，MongoDB等等

首先看架构图

NO.	组件	作用
1	mysql_exporter	MySQL监控数据采集组件
2	node_exporter	服务器机器监控数据采集组件
3	Prometheus	将mysql_exporter和node_exporter收集过来的数监控数据进行汇总和存储
4	Grafana	将Prometheus采集的数据图形化展示
5	Grafana-Dashboards	Grafana需要用到该项目中的JSON文件

2、安装 && 配置各个组件

(1)、部署&&启动 node_exporter

tar xf node_exporter-0.15.2.linux-amd64.tar
mv node_exporter-0.15.2.linux-amd64 node_exporter
cd node_exporter
nohup ./node_exporter &

(2)、部署&&启动 mysqld_exporter

tar xf mysqld_exporter-0.10.0.linux-amd64.tar
mv mysqld_exporter-0.10.0.linux-mv amd64 mysqld_exporter
export DATA_SOURCE_NAME='MySQL用户名:MySQL密码@(MySQL服务器IP:MySQL端口)/'

echo "export DATA_SOURCE_NAME='MySQL用户名:MySQL密码@(MySQL服务器IP:MySQL端口)/'" >> /etc/profile
cd mysqld_exporter
nohup ./mysqld_exporter --collect.info_schema.processlist --collect.info_schema.innodb_tablespaces --collect.info_schema.innodb_metrics --collect.perf_schema.tableiowaits --collect.perf_schema.indexiowaits --collect.perf_schema.tablelocks --collect.engine_innodb_status --collect.perf_schema.file_events  --collect.binlog_size --collect.info_schema.clientstats --collect.perf_schema.eventswaits &

(3) 部署&&启动 prometheus

mkdir /data
tar xvf prometheus-2.1.0.linux-amd64.tar -C /data
cd /data
mv prometheus-2.1.0.linux-amd64 prometheus
cd prometheus
vim prometheus.yml

修改配置文件 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.
    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
  - job_name : 'prometheus'
    static_configs:
      - targets: ['localhost:9090']
  - job_name: 'MySQL'
    static_configs:
      - targets: ['localhost:9104']
  - job_name: 'metrics'
    static_configs:
      - targets: ['localhost:9100']

启动 prometheus

/data/prometheus/prometheus --storage.tsdb.retention=30d &

这里的30d表示监控数据保留30天

浏览器访问效果如下：

(4) 部署&&启动 Grafana

tar xf grafana-4.6.3.linux-x64.tar.gz -C /data/prometheus
cd /data/prometheus
mv grafana-4.6.3 grafana
cd /data/prometheus/grafana
./bin/grafana-server &

此时可以通过浏览器访问3000端口

tar xvf grafana-dashboards-1.6.1.tar.gz
cd grafana-dashboards-1.6.1/dashboards
