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：

  1. postgres=#x
  2. Expanded display is on.
  3. postgres#select*from pg_stat_database where datname='postgres';
  4. -[RECORD1]+-
  5. datid|12896
  6. datname|postgres
  7. numbackends|1
  8. xact_commit|5692
  9. xact_rollback|3
  10. blks_read|155
  11. blks_hit|157853
  12. tup_returned|2566687
  13. tup_fetched|32370
  14. tup_inserted|0
  15. tup_updated|7
  16. tup_deleted|0
  17. conflicts|0
  18. temp_files|0
  19. temp_bytes|0
  20. deadlocks|0
  21. blk_read_time|0
  22. blk_write_time|0
  23. stats_reset|2014-09-23 01:23:12.123612+08
http://www.postgresql.org/docs/current/static/monitoring-stats.html
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。

2.1pgsnap

http://pgsnap.projects.pgfoundry.org/

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
  • #cd pgsnap.0
  • [root@zabbix pgsnap#./pgsnap.php-h localhost-p 5432-U postgres postgres
  • Connecting to postgres database.
  • Adding some HTML files.
  • Getting Misc informations.
  • Getting General informations.
  • sh:pg_config:commandnotfound
  • sh:pg_controldatanotfound
  • Getting Global Informations.
  • pg_buffercache
  • Getting Database Informations.
  • pg_buffercache
  • pgstattuple
  • pgstattuple on indexes
  • Getting Current Activities Informations.
  • Getting Statistical Informations.
  • Getting Tools Informations.
  • pgPool

    • 生成的结果，可参考下面的demo
    http://pgsnap.projects.pgfoundry.org/pgbench_snap_20120930/
    2.2 pgstatspack http://pgfoundry.org/projects/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
    #tar xfz /root/pgstatspack_version_2.3.1#cd pgstatspack
  • [root@zabbix pgstatspack#su postgres/install_pgstats.sh
  • Resultsfordatabase template1
  • Installing Statistics Packagefordatabase template1
  • Resultsfordatabase zabbix
  • Installing Statistics Packagefordatabase zabbix

    • 2）创建snapshot

    /bin/snapshot.sh
  • Resultsfordatabase zabbix
  • pgstatspack_snap
  • -
  • 1
  • (1 row)

  • -
  • 2
  • )

    • 3）生成报告
  • [root@zabbix pgstatspack]# su postgres ./bin/pgstatspack_report.sh /root/pgstatspack/bin /root/pgstatspack Please specify a username: postgres List of available databases: 1 . zabbix Please select
