Обсуждение: PostgreSQL monitoring

Do you guys have any suggestions on monitoring tools for postgresql
that would provide graphing of data & alerts ?
I have looked and tried out hyperic, munin, Nimbus but was hoping to
something better.

Thanks,

To monitor I use the following:

- pg_osmem: http://www.kennygorman.com/wordpress/?p=250
- pg_buffercache (contrib package in Debian)
- pg_top: http://ptop.projects.postgresql.org/
- ps
- pgd: http://www.kennygorman.com/wordpress/?p=260
- iotop: http://guichaz.free.fr/iotop/

And I am in the process of writing a bunch of scripts that the Zabbix
agent will execute to feed the server with information, so that alerts
and graphs can be produced.

Note that you have some plugins :

 * http://bucardo.org/check_postgres/ (plugin for nagios and others)
 * http://muninpgplugins.projects.postgresql.org/ (for munin)


I prefer nagios+munin or nagios+other-graph_tool.

Thanks for these links.  I am trying out the muninpgplugins but I get
"Global symbol "$statscope" requires explicit package name at /etc/munin/plugins//pg_exilog_stat_database line 179".
Execution of /etc/munin/plugins/pg_exilog_stat_database aborted due to compilation errors.


I have the following in /etc/munin/plugin-conf.d/munin-node

[pg_exilog*]
user postgres
env.dbhost localhost
env.dbname exilog
env.dbpass xxxxxxxxxx
env.dbuser exilog

Any idea why I get the error message?

Regards
Johann

Buggy script :-(

I will update the cvs and push a new version very soon.

Cool, I have actually been trying out Zabbiz 1.6.x now since I like it
better than munin.

Of course you would but, honestly, it is not on top of my TODO list. I
will have to do them, eventually, but I don't see it happening in the
next 4 weeks. Feel free to get started with something and I'll
contribute with what I have as soon as I can (quite busy at work at
the moment, sorry). :)

I did something in that way, check_postgres.pl is a good script to start from
(add a zabbix output perhaps).  I stop working on that because zabbix is too
painfull to use (*for me*).

Here some draft note about zabbix+check_postgres...Hope it can help.

Agent side:

zabbix_agentd.conf :

  UserParameter=pgs[*],sudo -u postgres
/usr/local/share/zabbix/check_postgres.pl --output=simple --db=$2 --action=$1 $3
| head -n 1
UserParameter=pgm[*],sudo -u postgres /usr/local/share/zabbix/check_postgres.pl
- --output=mrtg   --db=$2 --action=$1 $3 | head -n 1

sudoers :

Runas_Alias DB = postgres
User_Alias  SUPERVISOR = zabbix
Cmnd_Alias  CHECK_PG = /usr/local/share/zabbix/check_postgres.pl
SUPERVISOR  ALL=(DB) NOPASSWD: CHECK_PG


init checksum :

sudo su -s /bin/bash - zabbix
sudo -u postgres /usr/local/share/zabbix/check_postgres.pl  --db=DBNAME
- --action=settings_checksum --critical=0

Server side:

pgs :
 check_postgres.pl output simple
 pgs[ACTION,DBNAME]
pgm :
 check_postgres.pl output mrtg
 pgs[ACTION,DBNAME,EXTRA]
