public class HistogramLogProcessor extends Thread
HistogramLogProcessor will process an input log and
[can] generate two separate log files from a single histogram log file: a
sequential interval log file and a histogram percentile distribution log file.
The sequential interval log file logs a single stats summary line for each reporting interval.
The histogram percentile distribution log file includes a detailed percentiles and fine grained distribution of the entire log file range processed.
HistogramLogProcessor will process an input log file when provided with
the -i <filename> option. When no -i option is provided, standard input
will be processed.
When provided with an output file name <logfile> with the -o option
(e.g. "-o mylog"), HistogramLogProcessor will produce both output files
under the names <logfile> and <logfile>.hgrm (e.g. mylog and mylog.hgrm).
When not provided with an output file name, HistogramLogProcessor will produce [only] the histogram percentile distribution log output to standard output.
By default, HistogramLogProcessor only processes hlog file lines lines with no tag specified [aka "default tagged" lines]. An optional -tag parameter can be used to process lines of a [single] specific tag. The -listtags option can be used to list all the tags found in the input file.
HistogramLogProcessor accepts optional -start and -end time range parameters. When provided, the output will only reflect the portion of the input log with timestamps that fall within the provided start and end time range parameters.
HistogramLogProcessor also accepts and optional -csv parameter, which will cause the output formatting (of both output file forms) to use a CSV file format.
