- total number of errors, conflicts and unresolved conflicts
- activity
- total number of object loads, stores and total number of database connections
- cacheconnections
- number of active and total objects for each connection
- cachetotals

- dbsize
- size of the database in megabyte
Configure Nagios
Put a line like this in your nagios plugin configuration to make the plugin available:
command[check_zope]=/path/to/check_zope.py -H $ARG1$ -p $ARG2$ -d $ARG3$ -r $ARG4$ -a $ARG5$
Put a line like this in your nagios host configuration to use the:
service[maggie]=Zope;0;24x7;10;5;5;gocept;10;24x7;1;1;1;;check_zope!localhost!8080!50000000!10000!admin:password
Configure Nagios
To get the correct command configuration for "check_zope", copy the zope.cfg into your plugin config directory (debian: /usr/share/nagios/pluginconfig) or the commands.cfg in /etc/nagios/.
Then you can make use of the check_zope command for services:
define service{
use generic-service
host_name thezopehost
service_description Zope
check_command check_zope!thezopehost!8080!1000000000!500000!admin:password
}
Configure Munin
Symlink Plugins
Create symlinks in /etc/munin/plugins/
plugins using munin_client.py are named like:
/etc/munin/plugins/zope_<graph>_<server-index>[_<dbname>] eg: /etc/munin/plugins/zope_uptime_instance1 /etc/munin/plugins/zope_uptime_instance2 /etc/munin/plugins/zope_activity_instance1_db2
plugins using zeo_munin.py are named like:
/etc/munin/plugins/zeo_<graph>_<server-index>[_<storage>]
- graph
- see Munin data for a list of available graphs
- server-index
- host and port are looked up in the configuration MUNIN_ZEO_HOST|PORT_<server-index>
- storage
- name of the storage, optional, defaults to 1
examples:
/etc/munin/plugins/zeo_clients_ZEO1 /etc/munin/plugins/zeo_clients_ZEO1_1 /etc/munin/plugins/zeo_loadstores_ZEO1_temp
Configure Plugins
Add a configuration file to vim /etc/munin/plugin-conf.d/zope to tell the plugins how to connect to zeo server/clients:
[zope_*] user root env.MUNIN_ZOPE_HOST_instance1 http://localhost:8401/Control_Panel/munin env.MUNIN_ZOPE_AUTHENTICATE_instance1 admin:admin env.MUNIN_ZOPE_HOST_instance2 http://localhost:8402/Control_Panel/munin env.MUNIN_ZOPE_AUTHENTICATE_instance2 admin:admin [zeo_*] user root env.MUNIN_ZEO_HOST_ZEO1 localhost env.MUNIN_ZEO_PORT_ZEO1 8502
