So does anyone still wonder why we have so few women in our field?

Real nice, Töma.

@moderators, can we have a comment from you please about the acceptability

Could you describe the problem again? I’m interested, but I’m not sure that I 
quite understand what you want to do :-) were the last two addresses supposed 
to have 112 in the third octet?

Actually the sflow standard is flexible, and there are many fields widely 
available, including input interface and output interface, vlan/vxlan/mpls 
headers, etc. The sending device just needs to support the fields.

To give you an idea of some of the fields you can query from a TS server for 
example, here’s a description of one of the tables in the database: 
https://inmon.com/sentinel_help/8.0/help/en/report/api_view_traffic.shtml

Browse sflow.org for more fun info, including ideas for running sflow agents on 
your hypervisors (for eg correlating CPU and RAM usage per VM) etc :-)

I’ve had good results using Traffic Sentinel from Inmon. It’s got a nice 
queriable database backend and you don’t have to do much manual setup to get 
good results. The UI feels a bit 1995, but it works, and the API is practical 
and useful. It’s quite fast, too.

They can probably give you trial licenses to see if it works for you.

Completely agree, Alfie.
