I'm sure someone has figured out how to handle this data. What I am trying to do is index and extract all of the data in the table below. The data is a dump of /proc/user_beancounters and is one of the main places to get performance information for OpenVZ containers. I have a grand idea for generating dashboards with the information once everything is properly extracted.
The information is a touch trixy as one of the most important pieces of info (called the uid in the table, really called veid) specifies what container, or virtual machine the stats are for. That piece of info isn't on every row though, only on the rows that specify a different container from the line before it.
I'm not a regex wizard in this regard, however I know a lot of OpenVZ admins that would love to have this data for alerting, dashboard metrics, etc.
Note this is a dump of listing of approx 50-60 containers. the 0 container is the hardware node, and can be excluded.
