The po command stands for "print object."
The symbol $eax refers to one of the CPU registers. In the case of an exception, this register will contain a pointer to the NSException object. 
Note: $eax only works for the simulator, if you’re debugging on the device you’ll need to use register $r0. 

(lldb) po [$eax class]
You will see something like this:
(id) $2 = 0x01446e84 NSException

You can call any method from NSException on this object. For example:

// Support routines for automatically reporting user timing for common analytics platforms
// Currently supports Google Analytics, Boomerang and SOASTA mPulse
// In the case of boomerang, you will need to map the event names you want reported
// to timer names (for mPulse these need to be custom0, custom1, etc) using a global variable:
// rumMapping = {'aft': 'custom0'};
(function() {
var wtt = function(n, t, b) {
  t = Math.round(t);
  if (t >= 0 && t < 3600000) {
    // Google Analytics
