.net - Why use ETW over EventLog and vice versa? -

-

why should use event tracing windows (etw) on standard .net eventlog class, , vice versa? knowing we'll using quite few performance counters impact decision?

what know far:

  1. etw should perform better.
  2. etw more work integrate (e.g. .net event tracing windows)
  3. by selecting 1 of standard channels in etw (e.g. application, system), same information available in event log.

etw has many advantages.

first, in .net 4.5, far simpler use. eventsource class in 4.5 dramatically simplifies creating events within code.

however, without this, etw has huge advantages, though typically work differently, and, such, serve different purpose eventlog.

eventlog designed logging. etw, on other hand, allows trace application's progress in context of system whole. when start collecting etw events, collect them on system basis, lets not trace application, see what's happening in relation system it's running. using tool perfview, can see how specific portions of application operate while simultaneously seeing what's happening framework , windows whole.

i need duration of audio file series of voice announcements need play app. have added audio files resources , play fine. sample code below works perfect intended purpose: return duration of audio files. here code: float getdurationofaudioresource(locationenum loc, context context){ float duration = 0; try { mediaplayer mp; mp = mediaplayer.create(context, getaudioresource(loc)); duration = mp.getduration(); mp.release(); mp = null; } catch (illegalstateexception e) {e.printstacktrace(); logerror(25, "testdescitem:fault::could not open mediaplayer object audio resource.");} return duration; } here's weird thing. code called in main activity prepares set of audio instructions given test. there no errors within activity. second activity called, long string of errors on logcat. 03-07 13:23:43.820: i/actionlogger(21435): gentest_info_test #0 created. 03-07 13:23:43.830: i/actionlogger(21435): gente
