Requirements
Goal
Central system for storing statistics and timings
Stored data
What we might want to collect:
- per-stream/global decoded, dropped frames
- per-stream/global packets read/errors
- per-stream/global packets/bytes sent/errors (if sout)
- stats about httpd/vod, per request
Each thing could be stored as average, max, counter, ...
Data access
- Access stats from the GUI (simple)
- Dump HTTP server access data
- Dump some raw access data to output
Design
Data storage
Stats object
Stored as a singleton in p_libvlc
Counters
counter_sample_t
{
value
date
}
counter_elem_t
{
name
type
pp_samples / i_samples
}
- Name contains the originating object id, like "267.frames_displayed" .How to separate by http request ? "httpd_object_id.request_id.XXX" ?
- Type is one of MAX, LAST, COUNTER, DERIVATIVE, ...
Timing
timing_elem_t
{
name
last_time,
total_time,
total_samples,
running,
start_time
}
Reporting
- In GUI:
- Integrated in streams and media information for relevant items (make it available for VLM streams too)
- Where to put global data ?
- Data log:
- Make global options to enable and driver logger module
- Add some logging facility to httpd
- RRD output (muwahahahaha)
