监控postgreSQL的方法很多，本文做个简单的比较。
大的方面，监控方法可以分为以下几种
1 直接利用PG提供的性能统计数据
PG的很多性能数据可以通过查询pg_stat_或pg_statio_开头的系统表获取。
比如：
-
postgres=# \x
-
Expanded display is on.
-
postgres=# select * from pg_stat_database where datname='postgres';
-

2 PG专用的监控工具
pgsnap, pgstatspack,pgwatch,pg_statsinfo等。这些工具主要做PG的性能分析，状态查看的。不能做故障通知。
2.1 pgsnap
pgsnap是个PostgreSQL报告工具，不需要在数据库上安装任何东西，可以远程连接到数据库，然后通过PG已有的系统表查询统计数据并生成HTML报告。
使用例：
-
[root@zabbix ~]# tar xfz pgsnap-0.8.0.tar.gz
-
[root@zabbix ~]# cd pgsnap-0.8.0
-
[root@zabbix pgsnap-0.8.0]# ./pgsnap.php -h localhost -p 5432 -U postgres postgres
-

2.2 pgstatspack
前面介绍的pgsnap真的只是个某一时间点的snap采集工具，不能对一段时间内的变化做分析。
pgstatspack稍微进了一步，它把每次采集的snap信息存在数据库里，然后可以对2个snap信息进行比较生成文本的性能报告。
下面是使用的例子：
1）安装pgstatspack
-
[root@zabbix ~]# tar xfz /root/pgstatspack_version_2.3.1.tar.gz
-
[root@zabbix ~]# cd pgstatspack
-
[root@zabbix pgstatspack]# su postgres ./install_pgstats.sh
-
Results for database template1
-
Installing Statistics Package for database template1
-
Results for database zabbix
-
Installing Statistics Package for database zabbix
2）创建snapshot
-
[root@zabbix pgstatspack]# su postgres ./bin/snapshot.sh
-
Results for database zabbix
-
pgstatspack_snap
-
------------------
-
1
-
(1 row)
-
-
[root@zabbix pgstatspack]# su postgres ./bin/snapshot.sh
-
Results for database zabbix
-
pgstatspack_snap
-
------------------
-
2
-
(1 row)
3）生成报告
-
[root@zabbix pgstatspack]# su postgres ./bin/pgstatspack_report.sh
/root/pgstatspack/bin /root/pgstatspack
