Constructor & Destructor Documentation

__construct()

ProfilerExcimer::__construct

(

array

$params = []

)

Parameters

array

$params

Associative array of parameters: period: The sampling period maxDepth: The maximum stack depth collected cpuProfiler: A pre-started ExcimerProfiler instance for CPU profiling of the entire request including configuration. realProfiler: A pre-started ExcimerProfiler instance for wall clock profiling of the entire request.

Reimplemented from Profiler.

Member Function Documentation

close()

ProfilerExcimer::close

(

)

Close opened profiling sections.

Reimplemented from Profiler.

Definition at line 49 of file ProfilerExcimer.php.

Referenced by getFunctionStats(), and getOutput().

getFunctionStats()

ProfilerExcimer::getFunctionStats

(

)

Get the aggregated inclusive profiling data for each method.

The percent time for each time is based on the current "total" time used is based on all methods so far. This method can therefore be called several times in between several profiling calls without the delays in usage of the profiler skewing the results. A "-total" entry is always included in the results.

When a call chain involves a method invoked within itself, any entries for the cyclic invocation should be be demarked with "@". This makes filtering them out easier and follows the xhprof style.

Returns

array List of method entries arrays, each having:

• name : method name
• calls : the number of invoking calls
• real : real time elapsed (ms)
• real : percent real time
• cpu : CPU time elapsed (ms)
• cpu : percent CPU time
• memory : memory used (bytes)
• memory : percent memory used
• min_real : min real time in a call (ms)
• max_real : max real time in a call (ms)
