Stefan Sauer d9901e7019 stats: fix cpu stats printing 
Only print them if we have them. Also scale them by 10.0 as the are in
per-mille now.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 5e2770566f tracers: eliminate var_args 
Register tracer hooks as GCallback. Use macros for hook dispatch and cast the
hook functions back to the appropriate type.

Stefan Sauer f09dd66cf6 stats: don't warn on ".class" log lines 2015-10-05 20:59:39 +02:00
Stefan Sauer b10b10cf1e tracers: code cleanups 
Move static variables to instance variables. Add finalize methods. Remove code
that is commented out. Cleanup locking code.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 4881d1c16c tracer: use GQuark or strings for the hook id 
This way one can define new tracing probes without changing the core. We are
using our own quark table, as 1) we only want to initialize them if we're
tracing, 2) we want to share them with the tracers.

Stefan Sauer 1a3e218b89 tracer: simplify hook api 
Instead of a single invoke() function and a 'mask', register to individual
hooks. This avoids one level of indirection and allows us to remove the
hook enums. The message enms are now renamed to hook enums.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 7b24d76260 tracer: drop the HookId hid from the invoke method 
The MessageId is more detailed and anyway needed to interpret the varargs.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 4ab1e6e3f7 stats: fixup doc name and remove commented code 2015-10-05 20:59:39 +02:00
Stefan Sauer 4f6f8cb811 tracers: add metadata for the logged values 2015-10-05 20:59:39 +02:00
Stefan Sauer 3baaa4ba6f rusage: improve cpu load meassurements 
Get the number of cpus and scale process cpu-load accordingly. Switch the
cpuload to be per-mille to get smoother graphs. Add a bit more logging and use
the _OBJECT variant.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 2ef32c8840 tracer: remove commented code 2015-10-05 20:59:39 +02:00
Stefan Sauer 77fd813760 design: update tracer design 
Update the tracer event classes section. Add a performance section.
 2015-10-05 20:59:39 +02:00
Stefan Sauer d7acb27dee tracer: use GST_PTR_FORMAT to log the structure 
This way we only expand the structure when we're logging. This allows us to
meassure the pure tracing seperately from the logging.
Also add some comments on further improvements.
 2015-10-05 20:59:39 +02:00
Stefan Sauer dbb1897e9b rusage: implement windowing of cpuload 
Add a local help to the rusage plugin that supports windowing of values. We want
to generalize this for use in other plugins.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 018858980b rusage: announce the data format 
Rusage will now announce what is meassures and how it is logged. Use the new format in stats.
Cleanup the the code and naming.
 2015-10-05 20:59:39 +02:00
Stefan Sauer c13ee1f2e9 stats: improve cpu load meassurements 
Rename variables for clarity. Handle the initial disparity between debug time
and the time already spent in the proc and main thread.

Stefan Sauer c500372f5a design: update tracer design 2015-10-05 20:59:39 +02:00
Stefan Sauer b92ea7a0bc quarks: revert the quark changes, we not using them anymore 2015-10-05 20:59:39 +02:00
Stefan Sauer 46ea9729df tracer: split into tracer and tracerutils 
Keep tracer base class in tracer and move core support into the utils module.
Add a unstable-api guard to the tracer.h so that external modules would need to
acknowledge the status by setting GST_USE_UNSTABLE_API.

Stefan Sauer 757d3400cd latency: take stop time when buffer is handled
