perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi Chad,

There are no plans to add testspec_id to maddash because the owmesh.conf file 
(and thus the spec id) is going away completely in 3.4. You can already 
define multiple maddash "checks" that filter on different test parameters 
though. For example, for throughput you could have two grids with the exact 
same hosts but one is for UDP tests and another is for TCP tests. In the 
maddash check definition you'd just need to define a "command" option in one 
that has "-p tcp" in one and "-p udp". Likewise you would need to update the 
graph URL with whatever extra options it needs to grab the different results 
(iirc, bandwidthBraph.cgi has a "protocol=udp/tcp" GET parameter you could 
set in this example). I think another way to ask the question is what types 
of test parameters do you want to distinguish between tests and are they all 
supported as parameters to the graphs and underlying tools? 

Thanks,
Andy
