It's spring, and even though UConn just lost their first NCAA tournament opening round since 1979, it felt like the time was right for a new release of collectl especially since this one supports Lustre 1.6.4.3. If you're not familiar with collectl check it out at http://collectl.sourceforge.net/ and the main reason you should care is it's the one tool that lets you monitor lustre stats along side of virtually any other system metrics you may care to look at. It's also low overhead which means interactive one second monitoring intervals are no big deal. If you want to run it as a daemon it will collect samples every 10 seconds for a pretty accurate longer term view of the world. If you want to get an idea of what collectl can actually do, have a look at the short tutorial complete with screen shots at http://collectl.sourceforge.net/.
One key feature of collectl, at least as far as lustre is concerned, is that it dynamically looks for and responds to configuration changes! In other words if OSTs or file systems are added or removed, collectl recognizes and reacts. Anyhow, don't just take my word for it , check it out... -mark _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
