Hi Andy,

It is great to know the webpage can do this. But my main goal is to be able to find them in CLI. for example, how can I get a list of 100G nodes hosted in US with the lookup tool(or any other tool)?

Thanks,

Shawn

Hi,

On the stats.es.net web page you can query an exact speed by entering "nicspeed:100G" in search bar. Below is direct links to results for 40G and 100G:

40G hosts: http://stats.es.net/ServicesDirectory/#search=nicspeed%3A40G

100G hosts: http://stats.es.net/ServicesDirectory/#search=nicspeed%3A100G

If you want true greater than, then you will need to do some custom analysis by querying all the interfaces and finding the ones with the "interface-capacity" field above 10G. The lookup service by default only supports equality tests (no greater than or less than). I can talk you through that if going through the web page is not enough.

Thanks,

Andy

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.

Thanks,
