安装目录

grafana   /usr/local/grafana

prometheus /usr/local/prometheus

node_exporter /usr/local/prometheus/plugin

postgres_exporter /usr/local/prometheus/plugin/postgres_exporter

软件准备

  • grafana

          https://dl.grafana.com/oss/release/grafana-6.0.1.linux-amd64.tar.gz 

  • Prometheus

          https://github.com/prometheus/prometheus/releases/download/v2.8.0/prometheus-2.8.0.linux-amd64.tar.gz

  • Prometheus agent

  node_exporter

          https://github.com/prometheus/node_exporter/releases/download/v0.17.0/node_exporter-0.17.0.linux-amd64.tar.gz

          postgres_exporter

          https://github.com/wrouesnel/postgres_exporter

          https://github.com/wrouesnel/postgres_exporter/releases

一 安装步骤

1.监控服务器安装Grafana

# tar -zxf grafana-6.0.1.linux-amd64.tar.gz
# mv grafana-6.0.1/* .
# rm -rf grafana-6.0.1*

 修改conf/defaults.ini文件部分参数如下

data = /usr/local/grafana/data
logs = /usr/local/grafana/data/log
plugins = /usr/local/grafana/data/plugins
provisioning = /usr/local/grafana/conf/provisioning

启动grafana

# bin/grafana-server &

 登录查看

默认账号密码admin/admin

Grafana + Prometheus 监控PostgreSQL

2.监控服务器安装prometheus

--web.enable-lifecycle

作用:后期修改参数文件时不需要重启服务,可以通过api重新读取参数文件。

# tar -zxf prometheus-2.8.0.linux-amd64.tar.gz
# mv prometheus-2.8.0.linux-amd64/* .
# rm -rf prometheus-2.8.0.linux-amd64*
# ./prometheus --web.enable-lifecycle --web.enable-admin-api &

 登录查看

3. 各节点安装agent

   node_exporter

# tar -zxf node_exporter-0.17.0.linux-amd64.tar.gz
# mv node_exporter-0.17.0.linux-amd64 node_exporter
# rm -rf node_exporter-0.17.0.linux-amd64.tar.gz
# node_exporter/node_exporter &

postgres_exporter

该插件还未集成prometheus官网,需要从github下载.,分别下载源码文件,注意postgres_exporter二进制执行文件并不在该源码包里,需要单独下载。

源码 https://github.com/wrouesnel/postgres_exporter

二进制执行文件https://github.com/wrouesnel/postgres_exporter/releases

加入我自己定义的部分sql到custom.yaml文件

# cp queries.yaml custom.yaml

pg_stat_connetion:
  query: "select state,count(*) from pg_stat_activity group by state"
  metrics:
    - state:
        usage: "LABEL"
        description: "type of session state"
    - num:
        usage: "GAUGE"
        description: "type of session state"

pg_stat_long:
   query: "SELECT pid, runtime from (select usename, pid, EXTRACT(EPOCH FROM (now() - query_start))::INT as runtime FROM pg_stat_activity) as ss where runtime > 180 order by runtime desc limit 5"
   metrics:
     - pid:
         usage: "LABEL"
         description: "Pid of the client"
     - runtime:
         usage: "GAUGE"
         description: "current transactrion start time"

 启动postgres_exporter

# export DATA_SOURCE_NAME="postgresql://dbadmin:1qax2wse@172.16.101.54:5432/postgres?sslmode=disable"
# export PG_EXPORTER_EXTEND_QUERY_PATH="/usr/local/prometheus/plugin/postgres_exporter/custom.yaml"
# ./postgres_exporter &

 查看postgre_exporter

4. prometheus添加agent节点
