Add high-resolution timestamps to log files for debug situations
----------------------------------------------------------------
Key: QPID-3236
URL: https://issues.apache.org/jira/browse/QPID-3236
Project: Qpid
Issue Type: Task
Reporter: Kim van der Riet
Assignee: Kim van der Riet
In some performance-related debug situations, it would be useful to see the
time between logged events (in debug or trace mode). However, the standard log
timestamp has a 1 second resolution, and it does not help matters when hundreds
of events of interest all occur within the same second.
I propose to add a #define in qpid/sys/posix/Time.cpp which would change the
timestamp printed by the outputFormattedNow() method to an unformatted
second/nanosecond output. This define would be uncommented and compiled in when
needed, but remain commented out for normal use. A comment would explain its
use.
I am sure an equivalent change could also be made to the windows version in
qpid/sys/windows/Time.cpp.
