munin.plone 1.2

Plugins

Currently there is 1 plugin available:

• “contentcreation” - reports content creation and modification taken from portal_catalog

How to use it

• First include the package in your buildout instance slot:

  [instance]
  ...
  eggs =
      ...
      munin.plone
  zcml =
      ...
      munin.plone

• To create the pluging helper script you’ll also need to include the following, additional section and extend your parts definition:

  [buildout]
  parts =
      ...
      munin
  
  [munin]
  recipe = zc.recipe.egg
  eggs = munin.plone
  arguments = http_address='${instance:http-address}', user='${instance:user}', plone='plone'

  The arguments option is used to pass configuration values to the generated helper script, which is then used as the actual munin plugin (see below). Any settings for ip-address, http-address, port-base and user given in the instance section should be repeated here, separated by commas.

  Please be aware, that the variable names use underscores instead of dashes here — the following list shows all supported settings and their respective default values:

  • ip_address=’<ip-address>’ [‘localhost’]

  • http_address=<http-address> [8080]

  • port_base=<port-base> [0]

  • user=<user-credentials> [n.a.]

  • plone=<plone-site-id> [‘plone’]

  Either literal values or references to the instance part can be used here, i.e. “http_address=’${instance:http-address}’, user=’${instance:user}’”. Please note that the resulting line will be verbosely copied into the generated bin/munin script, so the extra quoting is required.

• Now you should be able to call the plugins as follow:

  http://localhost:8080/plone/@@munin.plone.plugins/contentcreation

  Where contentcreation is you plugin name. Please note that for security reasons the view requires the View management screens permission.

• Next you need to make symlinks from the helper script inside your buildout’s bin/ to the munin plugin directory. The helper script itself can assist you with this:

  $ bin/munin install /opt/munin/etc/plugins [<prefix>] [<suffix>]

  This will install the necessary symlinks in the given directory using either the provided prefix and suffix or else the hostname and current directory to assemble their names (see below).

  Alternatively, you may also install the desired symlinks yourself:

  $ cd /opt/munin/etc/plugins
  $ ln -s ~/zope/bin/munin company_contentcreation_site1

  Here /opt/munin/etc/plugins is your munin directory, ~/zope/ is the root directory of your buildout, contentcreation the name of the plugin you want to enable, company a placeholder for an arbitrary prefix and site1 the name which will be shown in munin.

• Finally configure the plugin in munin (this step can be skipped if you have correctly set up the arguments option as described in step 2 above):

  $ cd /opt/munin/etc/plugin-conf.d/
  $ vi munin.plone.conf
  ... [company_*_site1]
  ... env.AUTH myuser:myuser
  ... env.URL http://localhost:8080/plone/@@munin.plone
  .plugins/%s

  Here myuser:myuser are your Zope user credentials and localhost:8080 your site url. Please check munin for more information about plugin configuration.
