perfSONAR User Q&A and Other Discussion

Hi,

I've been working with a good sized MaDDash grid.  Every other day or 
so, a whole line goes orange on all the grids, like the agent has 
failed.  I find that the agent can still be logged into however. 
Further, a 'systemctl status pscheduler-*' shows all the pscheduler 
services active and green.  The pscheduler-runner.service does seem to 
have a long list of CGroup lines.  A simple 'systemctl restart 
pscheduler-*' has solved the problem in three out of three cases. 
Probably not normal behavior, is it?

My real question is that my throughput grid has more yellows than I'd 
like.  I think the TCP startup may be an issue.  I'd like to add the -O4 
option to the iperf3 command line.  Doing this hasn't been obvious after 
a day of poking around.  I'd hoped that ' 
/etc/pscheduler/tool/iperf3.conf' would be the place to add it.  All but 
one of the lines in the file are commented out, just '[iperf3]' is 
uncommented.   I looked at the python code which consumes this .conf 
file and the variable name to use seems like it might be 'omit = 4' or 
'omit_secs = 4' but neither seems to work.  What and where is the place 
to add options to the throughput tool command line?

Thanks,
Phil
