perfSONAR User Q&A and Other Discussion

Hi Ivan,

I have the pS toolkit v4.0.2 on Debian 1604. But I am trying to use the sls-client tool(http://docs.perfsonar.net/client_tools.html)or the webpage to obtain a list of 10G/100G nodes. It will be even better if it could provide distance or geographical information.

I would like to know if you have any other ways of doing this. Thank you Ivan.

Regards,

Shawn

Hello Shawn,

Could you please first specify the installation type you have, so that I am able to replicate and understand the problem?

Betreff: [perfsonar-user] lookup service client for node discovery

Greetings all,

I am trying to use the pS lookup service client tool to identify all 10G/100G nodes. When I run the command $ sls_report, it returns a sets of stats based on the criteria e.g. bundle version, interface speed etc.

Since it can count all hosts based on interface speed, is there a command that can return a list of hosts with interface speed >10Gbps? Also, can i do that on the lookup webpage with a filter? If not, any other tricks to obtain this information? Appreciate your response!

Below is a part of sls report.

Iface Speed (9):
                                                    count    percent
 10 Gbps                                             1181    44.48 %
 1 Gbps                                              1054     39.7 %
 unknown                                              292     11.0 %
 100 Mbps                                              59     2.22 %
 40 Gbps                                               41     1.54 %
 20 Gbps                                               15     0.56 %
 2 Gbps                                                 6     0.23 %
 undefined                                              5     0.19 %
 10 Mbps                                                2     0.08 %

Thanks,
Shawn
