(SM) Support Tip: Kubernetes logs use 'glog' - Google Logging Library

When reviewing a log from Kubernetes the following format is seen below. What does this mean?

Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
I0313 22:47:01.240753 21904 sched.cpp:635] Scheduler::statusUpdate took    23007ns
 
And so on....
 
Other entries might look like the following:
 
W0313
E0313
F0313
 
This is a default format of Google Logging Library - aka "glog". Below is how to decipher these types of log entries. The below is a sample:
 
[IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line]
I0313 22:47:01.240753 21904 sched.cpp:635] Scheduler::statusUpdate took    23007ns
 
I -- Level
03 -- month
13 -- 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
