I need to be able to control site users' bandwidth and diskspace usage.
At this point we are primarily concerned with bandwidth.
I thought I'd get some feedback on how I'm thinking about solving this issue:
- Create a module for Aegir that requires Apache module mod_cband (http://codee.pl/cband.html).
- Module provides a settings panel per site that allows for bandwidth limits to be set.
- Module implements hook_provision_apache_vhost_config which generates vhost config for each site that reflects the bandwidth settings.
And advanced features:
- Provide a Drupal module on the client site so they can monitor their bandwidth usage.
- Settings page to adjust CBandExceededURL (URL site goes to when bandwidth is exceeded)
- Cron job that monitors the bandwidth usage (via /cband-status?xml) and sends email alerts when bandwidth nears limits?
For the diskspace monitoring, I've not thought about it too much, but I'm thinking a drush script that runs du on the sites/site.com/files folder?
Another issue we might like to look at in the future is managing creation of mail & ftp accounts.
Feedback very welcome.
