NAME    [Toc]    [Back]

     acctcvt - convert accounting data to a different format

SYNOPSIS    [Toc]    [Back]

     acctcvt [options...] [infile]

DESCRIPTION    [Toc]    [Back]

     The acctcvt command is used to convert accounting data from one format to
     another.  The data	can come from a	file or	stdin (such as when used as an
     audit filter) and similarly can be	written	to another file	or stdout.
     Both SGI extended accounting and standard SVR accounting formats are
     supported.

     In	addition, output can be	in ASCII text.	The output can be in the form
     of	human-readable text, either in the format similar to that produced by
     sat_interpret(1M) or by acctcom(1).  The output can also be in the	format
     that can be fed into a post-processing tool like awk(1).

     Some input	formats	may contain data records that are not related to
     accounting	(such as system	audit information in the extended accounting
     formats).	These records will not be contained in the reformatted output.
     However, they can be copied verbatim to stdout in case acctcvt is being
     used together with	other tools that may need that information.  See
     audit_filters(5) and the Examples section below for information on	how
     this might	work with the System Audit Trail.

OPTIONS    [Toc]    [Back]

     -d	  Sets debug mode.

     -i	  Read input data as the second	or later stage in a pipeline of	audit
	  filters.  Equivalent to specifying "--input_source -",
	  "--input_format extacct6.5", and "--input_noheader".

     -o	  Run in "filter" mode:	all input is copied unchanged to stdout, with
	  the exception	that a file header will	be discarded.  This option
	  cannot be specified if "--output_destination -" was also specified.

     -q	  Suppresses warning messages (usually concerning invalid record
	  types) to stderr.

     -v	  When used with the text or text_acctcom output format, this
	  specifies that audit information not related to accounting should be
	  included in the output.  Otherwise, the option is ignored.

     --filter
	  Same as -o.

     --filter_hdr
	  Same as --filter except that a file header (if present) from the
	  input	source will also be copied to stdout.

     --input_format format
	  Specifies the	format of the input data.  Valid values	of format are:

	  extacct6.2	 IRIX 6.2 extended accounting format

	  extacct6.4	 IRIX 6.4 extended accounting format

	  extacct6.5	 IRIX 6.5 extended accounting format

	  svr4		 Standard SVR4 process accounting data

	  The default is extacct6.5.  Note that	for the	SAT/extended
	  accounting input formats, records unrelated to accounting will not
	  be included in the reformatted output.

     --input_header
	  Indicates that the input data	starts with a file header.  This is
	  the default for all input formats except svr4, for which this	option
	  is illegal (the svr4 accounting data format does not define a	file
	  header).

     --input_noheader
	  Indicates that the input data	does not begin with a file header.
	  This would be	useful if acctcvt were being used in a pipeline	of
	  audit	filters	and the	previous stage of the pipe discards the
	  header.  It is also the normal behavior for the svr4 input format.

     [--input_source] {	- | path }
	  Specifies the	source from which input	data should be taken.  If "-"
	  is specified (or the option is not specified at all) data is taken
	  from stdin.  Otherwise, the pathname of a file from which data is to
	  be read should be specified for path.	 Notice	that it	is not
	  strictly necessary to	specify	"--input_source" unless	the input file
	  begins with a	"-" character; the first unrecognized command line
	  argument that	does not begin with a "-" will be taken	as the input
	  source.

     --output_destination { - |	|cmd | path }
	  Specifies the	destination to which reformatted output	should be
	  written.  If "-" is specified	(or the	option is not specified	at
	  all) data is written to stdout.  If the first	character of the
	  destination is the character "|", then the remainder of the
	  destination will be taken as a command line and executed with
	  "/bin/sh -c";	the stdin of this second process will receive the
	  output from acctcvt.	Note that with most shells it will be
	  necessary to enclose cmd in quotes, both to protect the "|"
	  character and	so that	cmd will be treated as a single	argument to
	  acctcvt.  If the destination does not	begin with "|" then it is
	  assumed to be	the name of a file to which the	output data will be
	  written.

     --output_format format
	  Specifies the	format of the output data.  Valid values of format
	  are:

	  extacct6.2	 IRIX 6.2 extended accounting format

	  extacct6.4	 IRIX 6.4 extended accounting format

	  extacct6.5	 IRIX 6.5 extended accounting format

	  svr4		 Standard SVR4 accounting format

	  text		 Human-readable	text in	row format

	  text_acctcom	 Human-readable	text in	acctcom-like format

	  text_awk	 Text in awkable format; can only be specified with
			 extacct input format.

	  The default output format is text.

     --output_header
	  Indicates that a file	header appropriate to the output format	should
	  be written before any	accounting data.  For the extended accounting
	  output formats, this would be	useful when output is being sent to a
	  file that will later be processed by audit tools (such as
	  sat_interpret(1)) or other software that is expecting	standard
	  System Audit Trail data.  This option	cannot be specified along with
	  the svr4 or text_awk output format.

     --output_noheader
	  Indicates that no file header	should be included with	the
	  reformatted output.  This is the default behavior.

     -A	ash
	  Selects only processes that have an array session handle that
	  matches the ash argument.

     -C	sec
	  Selects only processes with total CPU	time (system plus user time)
	  exceeding sec	seconds.

     -I	chars
	  Selects only processes that transfer more characters than the	cutoff
	  number given by chars.

     -M	kbytes
	  Selects only processes with mean core	size exceeding kbytes KB.

     -n	pattern
	  Selects only commands	matching pattern that may be a regular
	  expression, as in ed(1), except that a + symbol indicates one	or



									Page 3






acctcvt(1)							    acctcvt(1)



	  more occurrences.

     -O	sec
	  Selects only processes with CPU system time exceeding	sec seconds.


     There are several "shorthand" versions of some of the longer option
     names.  These are:

	  short	  full option name

	  -f	  --output_destination
	  -i	  --input_format extacct6.5 --input_noheader --input_source -
	  -i62	  --input_format extacct6.2
	  -i62nh  --input_format extacct6.2 --input_noheader
	  -i64	  --input_format extacct6.4
	  -i64nh  --input_format extacct6.4 --input_noheader
	  -i65	  --input_format extacct6.5
	  -i65nh  --input_format extacct6.5 --input_noheader
	  -isvr4  --input_format svr4
	  -o	  --filter
	  -oh	  --filter_hdr
	  -o62	  --output_format extacct6.2
	  -o62nh  --output_format extacct6.2 --output_noheader
	  -o64	  --output_format extacct6.4
	  -o64nh  --output_format extacct6.4 --output_noheader
	  -o65	  --output_format extacct6.5
	  -o65nh  --output_format extacct6.5 --output_noheader
	  -osvr4  --output_format svr4
	  -otext  --output_format text
	  -oacctcom  --output_format text_acctcom
	  -oawk	 --output_format text_awk


     The following options only	apply to the text_acctcom output format:

     -a	  Prints array session handle; can only	be specified with extacct
	  input	format.

     -c	  Prints the number of logical I/O requests; can only be specified
	  with extacct input format.

     -e	  Prints the system exit status; can only be specified with svr4 input
	  format.

     -g	  Prints group ID.

     -h	  Excludes column headings from	the output.  Options -h	and -H are
	  mutually exclusive.

acctcvt(1)							    acctcvt(1)



     -H	  Prints column	headings on every page.

     -io  Prints columns containing the	I/O counts.

     -k	  Instead of memory size, prints total kcore-minutes, which is the
	  average resident set size of the process (in KB) if its execution
	  time is normalized to	one minute.  This is computed by keeping a
	  cumulative sum of the	process's resident set size (the process's
	  current resident set size is added to	the sum	HZ times a second).
	  This sum is converted	to KB and then divided by 60*HZ	to yield
	  kcore-minutes.

     -l	  Prints the tty information.

     -m	  Prints mean core size.  This is average resident set size of the
	  process (in KB) during its execution.	 It is computed	by taking the
	  cumulative resident set size (as computed for	the -k option) and
	  dividing it by the sum of the	system and user	CPU times.

	  This is the default print option.  If	you do not specify any other
	  print	options, -m is selected.  If you do specify other print
	  options and you want mean core size to print,	you must specify -m.

     -p	  Prints process ID and	parent process ID; can only be specified with
	  extacct input	format.

     -P	  Prints project ID; can only be specified with	extacct	input format.

     -r	rppage
	  Sets the number of records per page to rppage; must be specified
	  with the -H option.  The default is 75.

     -s	  Prints the service provider information (SPI)	for array session
	  records; can only be specified with extacct input format.

     -t	  Prints separate system and user CPU times.

     -V	  Combines some	I/O fields; must be specified with the -c, -io,	or -w
	  option; can only be specified	with extacct input format.

     -w	  Prints wait times; can only be specified with	extacct	input format.


     The following option only applies to the text_awk output format:

     -fs fsep
	  Sets the field separator to fsep.  The default is a blank.


     The text_awk output format	prints the following fields separated by a
     delimiter:
	  Command name

EXAMPLES    [Toc]    [Back]

   Converting IRIX 6.5 Extended	Accounting Records
     The format	of the SAT (System Audit Trail)	data stream used by extended
     accounting	changed	between	IRIX 6.2, IRIX 6.4 and IRIX 6.5.  If it	is
     necessary to read accounting data from one	version	of IRIX	using tools
     from a different release of IRIX, acctcvt can be used to convert the data
     from the format used by the one release of	IRIX to	the other.  For
     example, if the file "auditdata" contains IRIX 6.5	data, it can be
     converted to IRIX 6.2 format and written to the file "acctdata" with the
     following command:

	 acctcvt --input_format	extacct6.5 --input_source auditdata
		  --output_format extacct6.2 --output_destination acctdata

     This can also be done more	tersely	by taking advantage of the default
     option settings and shorthand option names:

	 acctcvt -o62 <	auditdata > acctdata

     The file "acctdata" can now be used with other tools that may be
     expecting the IRIX	6.2 extended accounting	format.

   Converting Accounting Data With Audit Filters    [Toc]    [Back]
     Some accounting software may read extended	accounting records directly
     from the System Audit Trail (SAT) using "audit filters" (see



									Page 6






acctcvt(1)							    acctcvt(1)



     audit_filters(5) for more details on this technique).  Software that does
     this and that was designed	for an earlier release of IRIX may in many
     cases still be able to run	on more	recent releases	of IRIX	by using
     acctcvt as	an audit filter.  For example, suppose a program that was used
     to	process	IRIX 6.2 extended accounting records was invoked by placing
     its command line in the file /etc/config/satd.filter-1.  In IRIX 6.5 this
     same software could be used in the	same way by adding acctcvt as an
     additional	filter that occurs before the accounting software.  To do so,
     the file /etc/config/satd.filter-0	could be created, containing:

	 acctcvt --output_format extacct6.2

     If	the accounting software	did not	expect to see a	SAT file header, the
     --output_noheader option should be	used as	well:

	 acctcvt --output_format extacct6.2 --output_noheader


   Using acctcvt With Other Audit Filters
     If	the system audit facility is being used	for conventional audit
     purposes in addition to collecting	accounting data, it may	be necessary
     to	pass unmodified	audit data on to other filters via stdout as well as
     writing reformatted data to a separate output file	or accounting program.
     acctcvt provides the -o and -f options (or	their long forms, --filter and
     --output_destination) for handling	this situation.	 The -o	option
     instructs acctcvt to copy all input data (except a	file header, if
     present) to stdout, where it can be read by a subsequent audit filter.
     The -f option instructs acctcvt to	write the converted accounting data to
     a specified file or command.  Thus, a sample satd.filter-*	file that
     causes IRIX 6.2 accounting	records	to be written to the file
     /var/adm/acctdata while passing unmodified	audit records along to stdout
     would look	like this:

	 acctcvt -o -f /var/adm/acctdata -o62

     If	it is necessary	to pass	the reformatted	data along to another program
     rather than a file, acctcvt can create a "tee" in the audit filter
     pipeline by starting a second command to which it passes the converted
     data while	still copying the unmodified audit data	to stdout.  To do
     this, use the -f option as	before,	but specify the	command	preceded by
     the character "|" instead of a filename.  For example, if the
     satd.filter-* file	contained this:

	 acctcvt -o -f '|/usr/bin/myacct -i -dir /acct'	-o62

     then the command "/usr/bin/myacct -i -dir /acct" would be started in a
     second process and	it would receive IRIX 6.2-style	extended accounting
     records from acctcvt via stdin.  In the meantime, acctcvt would still
     continue to copy unmodified IRIX 6.5 audit	records	to stdout for use by
     other filters.  Notice that the command is	enclosed in single quotes to
     protect it	from interpretation by the shell.  In more complicated cases
     it	may be helpful to write	a simple wrapper script	for the	second command



									Page 7

     to	avoid confusion.

   Handling SVR4 Accounting Data    [Toc]    [Back]
     In	addition to converting between different audit formats,	acctcvt	can
     also convert accounting data to or	from the older SVR4 "pacct" format.
     The following command could be used to convert IRIX 6.5 extended
     accounting	records	into SVR4 format, which	could then be passed along to
     SVR4 accounting tools like	acctcom(1):

	 acctcvt -osvr4	-f /var/adm/pacct < /var/adm/sat_9707201833

     Conversely, SVR4 accounting data could be converted into SAT format for
     use with tools which expect extended accounting format data (although
     much of the extended accounting information will be missing):

	 acctcvt -isvr4	-o65 -f	/usr/tmp/satacct < /var/adm/pacct


   Outputting in Text Format    [Toc]    [Back]
     The following command can be used to print	IRIX 6.5 extended accounting
     data in text_acctcom format.  The output includes the I/O counts and wait
     times.

	 acctcvt -oacctcom -io -w /var/adm/sat_9707201833

     The following command can be used to print	IRIX 6.5 extended accounting
     data in text_awk format, with the field separator being ",".

	 acctcvt -oawk -fs , /var/adm/sat_9707201833

NOTES    [Toc]    [Back]

     The SVR4 accounting format	contains considerably less data	than SGI
     extended accounting formats.  When	converting extended accounting data to
     SVR4 format, metrics not supported	by SVR4	will be	discarded silently.
     When converting SVR4 data to an extended accounting format, metrics not
     supported by SVR4 will be reported	as 0.  In addition, SVR4 does not
     split I/O metrics into separate counts for	units read or units written.
     When converting SVR4 data to extended accounting format, these combined
     I/O counts	will be	reported simply	as "read" data and the write counts
     will be 0.
