openoffice 2.0 does support the graphs. I could not move them around like in excel but I could definitely see the default view of them.

Always in single-node configurations. The easiest way to communicate the performance of a raid controller to other people was a series of 3d surface plots. Sadly, OpenOffice doesn't have those, so I had to switch to that commercial office package. I tried gnuplot, but frankly.... compare the readability of the final plot with excel and there was no comparison :-/ Perhaps Matlab... What I hoped for was something that also verified that the internal states of glm and the locking subsystem were as they should at every step of the test. Something that could certify that the hardware behaved as GFS expected it to when pushed more than test performance. -- birger -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
