[ltt-dev] [UST] ustctl cli

[Nils Carlson]

I've been thinking about the ustctl cli lately. Mostly because I need to 
add trace names to a lot of commands. The current api doesn't really 
provide an obvious way forward. What I'm going to do first is just try 
hack it in.

In the long-term though I'm wondering if we should move to something more 
elegant, more like git or route? What do people think?

Hi again,

Yes!

# ustctl enable <CHANNEL> <MARKER>
# ustctl set-path <NEW_PATH>
...

Although, since tracing session is the next step (actually ongoing), it 
might be good to have something like that ? :

# ustctl trace1_name <OPTIONS> <COMMAND>

(And for the options, I will go with lttctl that I think is better :)
   -o, --option OPTION
         Set options, following operations are supported:
         channel.<channelname>.enable=
         channel.<channelname>.overwrite=
         channel.<channelname>.bufnum=
         channel.<channelname>.bufsize=
         <channelname> can be set to all for all channels
         channel.<channelname>.switch_timer= (timer interval in ms)

In any case, for usability, we should come up with something else then 
long option like --enable-marker, --get-subbuf-size, ...

What do you think? Maybe telling us a bit what's your idea.

David

Yepp, though I would reorder it a bit, maybe more like

ustctl create-trace nils_trace
ustctl enable-marker nils_trace sendmsg_marker
ustctl bufsize nils_trace ust 2MB

or something like that...

But I have to admit I've been working with switches lately which all  
have nice custom CLI's with tab based help and command expansion and  
stuff so I'm a bit spoiled.
