[Ganglia-developers] mod_load on 3.0.0

[Matt M. <massie@CS.Berkeley.EDU>]

i just uploaded a new snapshot of 3.0.0 to
http://matt-massie.com/ganglia/

this snapshot has a real working module (mod_load) that collects
load statistics from a host using libmetrics.

mod_load is in the ./modules directory of the tarball.  you can take a
look at the source if you want to see how it works.  i think you'll that
./modules/mod_load/mod_load.c is very simple and self-explanatory.

mod_load just adds the directory and entries

/load/one
/load/five
/load/fifteen

wherever it is bound (in this example it's /ganglia/).  it will
be trivial to make a mod_mem and mod_disk and mod_net and etc etc..
using the metrics in libmetrics.=20

to run the demo
% gunzip < ganglia-3.0.0*.tar.gz | tar -xvf -
% cd ganglia-3.0.0
% ./configure
% make
% export GANGLIA_MODULE_PATH=3D"`pwd`/modules/mod_load/.libs"
% cd gangliad
% ./gangliad

open up a web browser to http://<demohostname>:8666/

or just run something like

while true; do curl http://localhost:8666/; done

to slam it.

i have 3.0.0. compiling just fine on windows now.. i just need to work
out a little dll magic since libtool is only making static libraries
right now.
