G'Day,

In the meeting today I'll talk about end use cases of tracing at Netflix.
As something to prompt my own memory, the following is a list of desirable
tracing features I recently created, based on the use cases. Sorry, don't
yet have a complete list of actual use cases, just the solutions to the use
cases! (This is a bit like saying the answer is 42; in the call I'll talk
about what the questions are).

Base features:
- Tracing of kernel tracepoints
- Tracing of kprobes
- Custom filters
- printf() on events
- Maps on events (to allow histograms, summary variables)
- Custom variables within and between events (eg, for saving timestamps and
timing latency)
- Means of doing custom statistics (eg, global integers)
- Means of doing frequency counting (eg, associative array variable type)
- Means of doing histograms (eg, array variable type)
- Access to tracepoint fields (for use in filters, printf, histograms)
- Access to kprobe return rval (" " ")
- Access to kprobe entry arguments (ideally arg1, arg2, ...; else registers)
- Access to kernel stack trace (for printing, or using as a key for
frequency counting)
- Access to user-level stack trace (" ")

Additional features:
- Custom profiling (99 hertz)
- Kernel debuginfo for walking kernel structs, and accessing kprobe entry
args as variables
- Tracing of uprobes
- Tracing of user markers (UST/USDT)
- User debuginfo for user structs and args
- Easy to use language
- Library of scripting features
- Nice one-liner syntax

Brendan
