CProfileLogRoute

system.logging
继承 class CProfileLogRoute » CWebLogRoute » CLogRoute » CComponent
可用自 1.0
源码 framework/logging/CProfileLogRoute.php
CProfileLogRoute displays the profiling results in Web page.

The profiling is done by calling YiiBase::beginProfile() and YiiBase::endProfile(), which marks the begin and end of a code block.

CProfileLogRoute supports two types of report by setting the report property:
  • summary: list the execution time of every marked code block
  • callstack: list the mark code blocks in a hierarchical view reflecting their calling sequence.
