pgpginbyproc.d(1m)

NAME
pgpginbyproc.d - pages pagedin by process name. Uses DTrace.

SYNOPSIS
pgpginbyproc.d

DESCRIPTION
pgpginbyproc.d is a DTrace OneLiner to a report the number of pages paged in by process name. This may be one way to help identify the process responsible for causing heavy read traffic to the disks. Docs/oneliners.txt and Docs/Examples/oneliners_examples.txt in the DTraceToolkit contain this as a oneliner that can be cut-n-paste to run. Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command.

EXAMPLES

This samples until Ctrl-C is hit.
    # pgpginbyproc.d

FIELDS

first field

second field

DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output.

EXIT
pgpginbyproc.d will sample until Ctrl-C is hit.
