Add TCP utilization and TCP errors reports, from sar -nTCP,ETCP #147

Closed Krysztophe closed 2 years ago

Krysztophe commented 2 years ago

See #141

This adds two reports below System/Network/TCP : TCP utilization and TCP errors.

That would have been useful with a customer whose problem was a lot of retrans/s above a certain network traffic. Errors were not logged at device level, only through sar -n ETCP.

I'm not sure to have found all the places to update, but this seems to work, and with --rotate too.

In the utilization report, I've not found how to put segments (iseg/oseg) both on a 2nd Y axis. As I understand, this is possible only for the last data series. I don't think this is really a problem.

I've left the DEBUG print , these are so useful.

Real life example: TCP util TCP err
