Class DbFilterStats

java.lang.Object

com.sleepycat.je.util.DbFilterStats

public class DbFilterStats
extends Object

Transform one or more je.stat.csv statistics files and write the output to stdout. A set of column names is used to specify the order and which columns are written to the output. The utility is used to create an output file that is easier to analyze by projecting and ordering only the data that is required. Each user specified column name will either be a exact match of a column in the file or a prefix match. In order to output the "time" and all "Op" group statistics a column list "time,Op" could be used. Multiple input files are processed in the order specified on the command line. Duplicate column headers are suppressed in the output when processing multiple input files.
