vzstats update

Vzstats, which we introduced at the end of May, turns 4 months today. While it's still a baby, we can already say it is showing some great potential. Current stats are at about 13 000 servers running OpenVZ, with more than 200 000 containers. The amount of newly registered hosts is not going down, so I assume we'll have more than 20K active servers and at least 300K containers by the end of year.

Let's see what an average OpenVZ host looks like. It's an 8 core machine with 16 GB of RAM and 700 GB of disk space on /vz, used less than by 20%. This Joe is hosting only 8 containers, of which 4 are CentOS, 2 Debian, 1 Ubuntu and 1 is something else. Pretty average, eh?

What would be the ultimate OpenVZ host then? This one is a 64 cores monster with 1 TB of RAM and 50 TB of disk space, running about 1000 containers.

You can see much more stats like that at the project server site, http://stats.openvz.org/. The problem, though, is that not all stats can be represented in a meaningful way. For example, with vzstats 0.5.1 we introduced top-ps script, showing top 5 processes in every running container. The idea was to have something similar to Debian's popcon, but taking process names rather than package names into account. We have received lots of data but, frankly speaking, we don't really know how to process all this. I tried a number of various queries and came out with some stats like "60% of all containers run a web server", but all in all, this is not so useful (or interesting) for OpenVZ development. More to say, users raised a concern that such stuff should not be looked into at all. That sounds about right, so we have just released vzstats-0.5.2 with the top-ps script removed.

We would like to thank all users who are participating in vzstats. Please continue to do so, and if you have any concerns, please speak up -- we are listening.

Has the new vzstats package been pushed to the rpm repo? It doesn't show up as an update for me.

Nevermind. Just tried again and it showed up.
