Health Monitoring
Hey,
I am looking for healt monitoring software for my centos5.1 box. Nothing
crazy (like nagios), just something that records memory/cpu usage every min
to 5 mins.
I added some vmware stuff and was looking to see when if swap gets used and
cpu spikes.

Hi Evan
Thanks for the email. I had a look at gcc implementation of TBAA and I think
three main steps in implementation of TBAA for LLVM will be this:
April 20 ~ May 23: I will read gcc implementation in depth and play around
with LLVM code.
May 23 ~ July 6: Implementation and test of a simple version of TBAA that
does not work with all aggregate types. I think part of the coding required

Hi Ehsan,
All of the projects you have listed are quite interesting. If I were
to advocate for one, it would be #2. I think the scope of work is
perfect for GSoc.
I'd encourage send out a more concrete proposal when you're ready.
Thanks,
Evan
