Enhancement Request - show errors on link about ostinato HOT 9 CLOSED

Srivats,

Hope all is well and HAPPY NEW YEAR to you.  Just curious - since it looks like 
you are "looking for things to add" - do you think getting a link error 
indication (Issue 28) might be in the cards for a future release?  I would 
think this shouldn't be too hard to implement (at least on Linux) since the 
info should be available.
Aside from this, and scripting support ;-) (to allow Ostinato to be a "canned" 
operation", something I can have anyone setup) this has most everything I need.

Much appreciate all your hard work and support.

Regards,
 Werner H. 

@werner: Thanks for your wishes! Would the errors from the output of 'cat 
/proc/net/dev' work for you? Not sure if they are the same that 'ethtool -s' 
reports.

btw scripting support is not in the near future - I need to do some major 
refactoring and rearchitect parts of the code before I can start supporting 
scripting - but it's definitely in the plan.

Srivats,

Sorry it took me a while to respond - I've been off at a conference. 

Yes - I think the error info from 'cat /proc/net/dev' would work fine.  The RX 
errs would be the primary one, but indicating RX drops and maybe fifo & frame 
would be good too.  Again - when you clear the Ostinato display, you want these 
statistics cleared also (at least on the Ostinato display).

I see that /proc/net/dev also has a column for TX errs - but don't know how 
that will ever show anything (I understand RX error, but not TX error?).

No worries on the scripting (we'd all love to have it, but realize that's a 
heavy lift).  Hopefully something like adding these errors isn't too big a 
change.

Regards,
 Werner

@werner: I just pushed in a changeset to support rx error stats on Linux. Build 
from source and give it a shot. If you see any issues, let me know - I haven't 
had a chance to test it thoroughly

For now the Linux error stats are from /proc/net/dev (similar to the rx/tx 
stats), but in future this will be changed to use netlink and retrieve more 
detailed stats as well as link state.

Srivats,

Great Job!!!  I just downloaded the updates and the Port Drops, errors ..etc 
now get displayed.  I disconnected my cable briefly and errors were nicely 
shown.  As requested, these get "zero'd" out when clearing the statistics - 
just like I wanted.

Well done!

Many thanks,
 Werner

This issue was updated by revision 09dd87336e34.

revision b781e68848cd added support for stats using netlink for Linux - link 
state info is now available

Marking this issue as closed - any new error stats related enhancements should 
be raised as a new issue
