Parameters:

interval -

Method Detail

getCommand

public List<String> getCommand()

Generate command to write performance counters on the console.

The sample interval format is -si [hh:[mm:]]ss.

Note: typeperf supports csv, tab, and bin output formats. However specifying tsv (tab delimited) causes it to always write on a file so I am using csv (comma delimited, which is the default in any case).

Specified by:

getCommand in class AbstractProcessCollector

Throws:

IOException

getProcessReader

public AbstractProcessReader getProcessReader()

Specified by:

getProcessReader in class AbstractProcessCollector

getCounters

public CounterSet getCounters()

Declares the performance counters to be collected from the Windows platform.
