Improving the efficiency of information collection and analysis in widely-used IT applications

HPL-2010-164 (R.1) Improving the efficiency of information collection and analysis in widely-used IT applications - Blagodurov, Sergey; Arlitt, Martin
Keyword(s): efficiency, collection, analysis, DataSeries, Apache, Bro, Web server, Intrusion Detection System
Abstract: Modern IT environments collect and analyze increasingly large volumes of data for a growing number of purposes (e.g., automated management, security, regulatory compliance, etc.). Simultaneously, such environments are challenged by the need to minimize their environmental footprints. A general solut ...

kgmon

KGMON(8)						      System Manager's Manual							  KGMON(8)

NAME

       kgmon - generate a dump of the operating system's profile buffers

SYNOPSIS

       /usr/sbin/kgmon [ -b ] [ -h ] [ -r ] [ -p ] [ system ] [ memory ]

DESCRIPTION

       Kgmon  is  a  tool used when profiling the operating system.  When no arguments are supplied, kgmon indicates the state of operating system
       profiling as running, off, or not configured.  (see config(8)) If the -p flag is specified, kgmon extracts profile data from the  operating
       system and produces a gmon.out file suitable for later analysis by gprof(1).

       The following options may be specified:

       -b     Resume the collection of profile data.

       -h     Stop the collection of profile data.

       -p     Dump the contents of the profile buffers into a gmon.out file.

       -r     Reset all the profile buffers.  If the -p flag is also specified, the gmon.out file is generated before the buffers are reset.

       If  neither -b nor -h is specified, the state of profiling collection remains unchanged.  For example, if the -p flag is specified and pro-
       file data is being collected, profiling will be momentarily suspended, the operating system profile buffers will be dumped,  and  profiling
       will be immediately resumed.

FILES

       /vmunix - the default system
       /dev/kmem - the default memory

SEE ALSO

       gprof(1), config(8)

DIAGNOSTICS

       Users  with only read permission on /dev/kmem cannot change the state of profiling collection.  They can get a gmon.out file with the warn-
       ing that the data may be inconsistent if profiling is in progress.
