postgresql性能分析工具-pgstatpack-2.3.3.1

一、前言
数据库日常运行过程中的性能监控和状态判别，是数据库日常的运行维护工作中重要部分之一。也是我们平时对数据库进行性能问题排查、系统优化的一个重要凭证。
Oracle数据库，通过AWR报告、ASH报告对数据库的某个时间段的运行状态及性能进行信息的收集和统计，然后判断这段时间的数据库运行性能瓶颈。究其根本，Oracle会在每隔1s（默认）收集当前数据库的非空闲等待事件信息、会话信息等，并存放于相关的ASH视图中。AWR报告则是每小时(默认、可设置)，对数据库的运行情况保存一个快照信息，在进行性能分析的时候，则可以通过awr相关视图或者awr报告获取到在一段事件内，数据库的运行情况。在9i前，AWR被称为statpack。在9i后，则被正式命名为awr。
但是对于postgreSQL来讲，目前并没有在其中集成类似于AWR的功能。因此，对于PostgreSQL，我们只能采取选用其他的工具包来实现该功能，从而帮助我们更好的监控、获取一个时间段内postgreSQL数据库的性能。
二、工具下载地址
pgstatpack，则是一个对于PostgreSQL非常好的性能分析工具，其部署简单轻便，使用方便。可以通过启用定时任务的方式，对PostgreSQL数据库保存快照，帮助用户进行比对分析。
目前，我们可以下载到的版本是：pgstatpack-2.3.3
下载地址：
http://www.xenialab.it/meo/web/pub/pgstatspack-2.3.3.zip
但是在使用测试过程中，发现该版本部分内容并不是特别完善，比如表、sql、索引等快照信息并没有收集。
所以，在使用的过程中，为了更贴近实际使用情况，我对该版本的工具包进行了进一步的优化，完善了报告内容、表收集内容、视图收集内容，以及生成快照、删除快照、生成报告的脚本。

(大家可以直接下载下来使用，并根据实际情况进行修改)。
三、工具使用
1）简介
接下来，我对该工具的安装、使用方法等做一个简单的介绍：
在该工具中，核心文件主要是以下几个：
1.文件夹bin中，存放着三个.sh脚本
snapshot.sh
delete_snapshot.sh
pgstatpack_report.sh
其中，
snapshot.sh脚本，是通过linux主机的crontab进行设置，可以定时执行该脚本，为postgresql收集快照，用于记录快照时刻的数据库运行情况；
delete_snapshot.sh脚本，也是通过Linux主机的crontab进行设置，可以定时执行该脚本。为postgresql数据库删除历史快照；
pgstatpack_report.sh脚本，可以直接执行，获取相关快照中的信息，生成两个快照期间的数据库运行情况，类似于oracle的AWR报告。
2.sql文件夹文件夹sql中主要存放了创建各个快照的表信息、视图信息以及创建快照的函数、删除快照的函数、获取工具安装基础信息等。
主要文件如下：
pgstatspack_create_snap.sql，用于创建快照生成函数
pgstatspack_create_tables.sql，用于创建快照相关表、视图，做安装用
pgstatspack_delete_old_stats.sql，用于创建删除快照函数
pgstatspack_remove_tables.sql，用于删除快照表，做卸载用
3.install_pgstats.sh
该脚本主要用于安装工具
4.pgstatspack_stat_explanation.txt
该文本是对各个参数进行说明
2）安装
1.解压包
unzip pgstatspack-2.3.3.1.zip
2.使用具有Postgres数据库superadmin权限的用户执行脚本安装脚本：
sh install_pgstats.sh
输入postgresql端口即可
3）使用
为了方便使用，最开始我们需要把pg_stat_statements插件部署上
指定定时任务，收集快照：
crontab -e
#每分钟执行一次
/1 * * * * sh snapshot.sh
#所有快照保存30天
* 30 * * * * sh delete_snapshot.sh
生成报告：
sh pgstatpack_report.sh
输入数据库名字和数据库端口即可生成报告。
四、示例
安装成功后，可以看到的每个数据库中会存在以下表、视图、序列
