Method Detail

main

public static void main(String[] args)
                 throws Exception

Runs the httpd server. When the optional file(s) are given, they will be read into a CounterSet on startup. This is useful for post-mortem analysis. The usage is

 [-p port] [-d {debug,info,warn,error,fatal}] [-filter filter]* [-regex regex]* [-events file] file(s)
 

where

-p

The port at which httpd server will answer queries

-filter

Each instance of this argument specifies a string to be matched and is used to generate a Pattern which will filter the counters read from the file(s). If there are multiple instances they are combined together by an OR.

-regex

Each instance of this argument specifies a regular expression to be matched and is used to generate a Pattern which will filter the counters read from the file(s). If there are multiple instances they are combined together by an OR.

-events

An optional file of Event s logged in a tab-delimited format

-events

An optional file of Event s logged in a tab-delimited format

file(s)

XML representations of logged CounterSets

Parameters:
