This is a default format of glog libraray

 [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line]

For example 

I0909 22:47:01.240753 21904 sched.cpp:635] Scheduler::statusUpdate took    23007ns
  • I -- Level
  • 09 -- month
  • 09 -- date
  • 22 -- hour
  • 47 -- minute
  • 01 -- second
  • 240753 -- micro second
  • 21904 -- thread id
  • sched.cpp -- source file
  • 635 -- source file line
  • Scheduler::statusUpdate took 23007ns -- message

Now, @haosdent has already provided the concrete answer. Just for the sake of completeness, we're using glog in Apache Mesos for logging.
