A Munin plugin for Magento platforms.

This plugin allows you to monitor various statistics over time from Munin, such as:

• The number of customers
• The number of orders (last hour and total)
• The number of products and their types
• The biggest tables in your DB
• The biggest log files

Only a few sample monitors are provided with this package. You are encouraged to implement more in order to gather more data into your Munin server.

This plugin supports multiple Magento instances on the same node (see Configuration).

SCREENSHOTS OF GENERATED GRAPHS ARE NOT YET AVAILABLE, SORRY FOR THE INCONVENIENCE :(

• Magento CE 1.4+ or Magento EE 1.9+
• Munin-node (on the Magento server)
• Munin (on the central Munin server)
• PHP CLI
• awk

1. Create a link to the munin plugin provided in src/shell/arrakis/munin_plugin/magento_ into your munin-node plugins directory (generally /etc/munin/plugins). Don't forget to make it executable. You may copy this file instead of linking it.
2. Install the Magento module by copying the content of the directory src into your Magento instance. You need to flush the cache to apply the changes. Even if the module is extremely light (no setups, no observers, no rewrites, etc.) you should validate that the module is not generating side-effects on your platform before pushing it into a production environment.
3. Copy the plugin configuration file from src/shell/arrakis/munin_plugin/conf/magento into the directory /etc/munin/plugin-conf.d.

Edit the file /etc/munin/plugin-conf.d/magento you just copied and define the different local Magento instances you want to monitor.

The available directives are as follow ({id} here is the ID of the Magento instance, and should be incremented for each one):

env.mageInstance{id} (Magento instance's root dir)

env.mageinstance{id}_label (Magento instance's label)

env.mageinstance{id}_name (Magento instance's name - ONLY LETTERS/NUMBERS/UNDERSCORES)

Example:

env.mageinstance1 /var/www/html/magento
env.mageinstance1_label My Magento Shop
env.mageinstance1_name my_magento_shop

You can enable each monitor provided by the module indivually. To list the available monitors, run the following command as a privileged user:

root@myhost:~# munin-run magento_ suggest

magento_catalog_productcountbytype
magento_catalog_productcountbywebsite
magento_db_biggesttables
magento_log_biggestfiles
magento_sales_ordercountbystate
magento_sales_recentordercount

If you're satisfied with the results, you can create the links to different monitors with the following command (from Munin plugins dir):

root@myhost:/etc/munin/plugins# for p in $(munin-run magento_ suggest); do ln -s magento_ $p; done

Limitation: Currently monitors are enabled once for all local instances.
