[Lustre-discuss] Announcing new release of collectl

[Mark Seger]

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...
