2.5 Stats configuration

-----------------------

snf-cyclades-gtools comes with a collectd plugin to collect CPU and network

stats for Ganeti VMs and an example collectd configuration. snf-stats-app is a

Django (snf-webproject) app that serves the VM stats graphsmm by reading the VM

stats (from RRD files) and serves graphs.

To enable / deploy VM stats collecting and snf-stats-app see the relevant

documentation in the :ref:`admin guide <admin-guide-stats>`.

If you were using collectd to collect VM stats on Debian squeeze and you are

upgrading to Wheezy, you will need to upgrade your RRD files. Follow the

instructions on the collectd v4-to-v5 migration `guide

<https://collectd.org/wiki/index.php/V4_to_v5_migration_guide>`_.

You will proabably just need to run the `migration script

<https://collectd.org/wiki/index.php/V4_to_v5_migration_guide#Migration_script>`_

provided.

If you were using a previous version of snf-stats-app, you should also make

sure to set the ``STATS_BASE_URL`` setting in ``20-snf-stats-app-settings.conf``

to match your deployment and change the graph URL settings in

``20-snf-cyclades-app-api.conf`` accordingly.
