Also Zopkio depends of Naarad, that can parse a CSV file and create metrics and SLA over those metrics, plot graphs and so on. Pretty nice tool!!! > > I'm wondering if we could start to test something and maybe show it at AsiaBSDCon and BSDCon(Canada) next year? What do you think? > What I need right now would be a list of tests that we want to perform as well as what parameters we would like to take as metrics to compare.\ For tests, we can start with this list: https://github.com/dlangille/zfs_benchmarks/issues <https://github.com/dlangille/zfs_benchmarks/issues>; We can start as soon as I figure out how to provide access to the testers. See above re serial connection. I want to provide access, but I want to keep access restricted to only this box and not to the rest of my home LAN. I plan to do this via a VLAN. I could fire up a Rasperberry Pi and allow ssh into that. Will that be enough power for what you need to do? — Dan Langille http://langille <http://langille/>.org/ [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org iQJ8BAEBCgBmBQJWS3ywXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ1MTE2RjM0ODIzRDdERDM4OTY0OUJBNzdF QjIxNTlERUU5NzI3MzlGAAoJEOshWd7pcnOfO/4P+gOuILl+TjKn3E8fpTvF0Y/D rHT5EjCYZ3KANMXfSDCUk9kceA/0nKLcjLagVYirzl2VzgpPhfPcdb6C1AfBHCUT 7NvHUh/aMJf9qn1I9nGQflRdyJm6zHTBjM8WtsXaYj7Tqr5frOzBMLsfQl+UUTx5 HS9WumFMFY7QI55CG5kFkDuJpgd8u+hy8ytz7mZ6CDPjr9hGEDu8U35+983XqAo0 TnBXk/TbRSyGoGfTgaAY5SujJBMiu1iZkVi/zpm5qSgvVmj1OqaWoo8JpqchSCSZ gDDprvq6tskVgnVWkjeakQgm+4hAUkJRuUcRgOU/ZG0WahPsqT/77B6ftLMqK5fu 4hBZYVjq3aIteebUE2rcf9/GSnUtRAHBu+EbqmaQwgrPW1Z4V7/uWtL85W5sB7HK vP6MR2OPWizEOb95bJl85e+N46RoqXejvYNu4Co6l+9T8UldYm1FF72cVzIjMEXz xc22WQPTiNym1yOFYdn1+UUJ9w7I5O0LdufTqsnqdlaWpTNog2yC31o9/FJUDTJG /xKmpv8sUoYdDz6qI1xrgr/MdLlfsl4IwlEn0WOebAyU6yrUGFMA0MEpCWQwgXd/ aIceqrgsjDHTKPUbrJeXq505F3uUSFO76ZmJ7/sH/fcwjuFjKA85ANsP3z3R/gcH Mwe96Kbl3BDeD4hjYpZU =ohCS -----END PGP SIGNATURE-----
