public class LogProfiler
extends java.lang.Object
```
The log profiler is a profiler for the Avalon log-files. The Avalon log-files should be created with at least a DEBUGLEVEL middle (5) to get useful information. The profiler counts the number of method calls and which method is called how many times. The profiler counts the order of used time in the log file. The profiler shows the number of AoExceptions which are available in the log-file. The profiler counts the number of ThreadRegister delay, each time the client request is delayed because there where to many objects waiting for delete of the memory. The profiler evaluates the times of methods (and counts of evaluation): For each method it shows minimum time, average time, maximum time, total time, the linenumber, where the maximum time occurs and the evaluation count. The profiler evaluates the count and total-time-amount of groups of delay times. When the format of the log-file change the profiler must be changed to.
