I think the most straightforward thing to do would be to use Google Analytics. It has an API now (and Drupal module<http://drupal.org/project/google_analytics_api>) that you could use to pull in data and build custom reports. The biggest downside I know is that you're prohibited per terms of use on tracking individual users so all data is aggregate. --Kyle Mathews kyle.mathews2000.com/blog http://twitter.com/kylemathews On Wed, Apr 28, 2010 at 8:53 AM, Ken Winters <kwinters@coalmarch.com> wrote:
I'm going to be writing an OG analytics package for a medium sized non-profit and contributing it back to the community, and would like some guidance on specific technologies.
First, some background. The site traffic is almost entirely OG-based and requires a login to access. There are a few dozen public pages as well. Other than a lot of custom content types, the OG install is similar to GDO. The site is currently D5, with plans to upgrade to D7 in the fall (yes, I realize D5 is going to be a lot of extra work).
The goal priorities are (in descending order of importance):
* Capable of providing the needed metrics * Quality reports and graphing * Expandable with later module integrations (not just OG) * Scalable * Reasonably installable * Compatible with shared hosting (requiring SSH access is probably fine)
Metrics desired:
* Session length * Nodes viewed (aggregated by content type) * Searches made (query and number of results returned) * Eventually also taxonomy integration
Each would be stored with uids, and each Group would provide an aggregate total based on group membership.
In addition to data collection and processing, I'm also going to need a reporting framework that will provide results as HTML and CSV export of table results (one day resolution).
There have been many posts on the subject, but nothing that provides an obvious starting point:
* http://groups.drupal.org/node/20452 * http://groups.drupal.org/node/20889 * http://groups.drupal.org/node/21563 * http://drupal.org/project/nagios
The underlying technologies I've seen thrown around are Google Analytics, Cacti, Munin, RRDtool, and Nagios. Open source is desirable but not at the expense of critical features.
If anyone can provide guidance about approaches or eliminate some of the technologies, it would be greatly appreciated. I want to avoid a solution that is great for a small number of people but won't ever reach wide adoption.
Thanks,
