NAME

       otfaux - otfaux

DESCRIPTION

	      otfaux - append snapshots and statistics to existing otf traces

	      at given 'break' time stamps.

       otfaux [Options] <file name>

	      Options:

       -h, --help
	      show this help message

       -V     show OTF version

       -b <size>
	      buffer size for read and write operations

       -n <n> number of breaks (distributed regularly) if -p and -t are not set, the default for -n is 200 breaks

       -p <p> create break every 'p' ticks (if both, -n and -p are specified the one producing more breaks wins)

       -t <t> define (additional) break at given time stamp

       -F     force overwrite old snapshots and statistics

       -R     delete existing snapshots and statistics only

       -f <n> max number of filehandles output

       --funcgroups
	      create functiongroup summaries instead of function summaries

       --filegroups
	      create file group summaries instead of file summaries

       -v     verbose mode, print break time stamps

       -a     show advancing progress during operation

       --snapshots
	      write ONLY snapshots but NO statistics

       --statistics
	      write ONLY statistics but NO snapshots

       -s a[,b]*
	      regard  given  streams only when computing statistics.  expects a single token or comma separated list.  this implies the '--statis-
	      tics' option!

       -l     list existing stream tokens

CTLSTAT(8)						    BSD System Manager's Manual 						CTLSTAT(8)

NAME

     ctlstat -- CAM Target Layer statistics utility

SYNOPSIS

     ctlstat [-t] [-c count] [-C] [-d] [-D] [-j] [-l lun] [-n numdevs] [-w wait]

DESCRIPTION

     The ctlstat utility provides statistics information for the CAM Target Layer.  The first display (except for dump and JSON modes) shows aver-
     age statistics since system startup.  Subsequent displays show average statistics during the measurement interval.

     The options are as follows:

     -t 	 Total mode.  This displays separate columns with the total CTL read and write output, and a combined total column that also
		 includes non I/O operations.

     -c count	 Display statistics this many times.

     -C 	 Disable display of CPU statistics.

     -d 	 Display DMA operation time (latency) instead of overall I/O time (latency).

     -D 	 Text dump mode.  Dump all available statistics every 30 seconds in a text format suitable for parsing.  No statistics are com-
		 puted in this mode, only raw numbers are displayed.

     -h 	 Suppress display of the header.

     -j 	 JSON dump mode.  Dump all available statistics every 30 seconds in JavaScript Object Notation (JSON) format.  No statistics are
		 computed in this mode, only raw numbers are displayed.

     -l lun	 Request statistics for the specified LUN.  This option is incompatible with total (-t) mode.

     -n numdevs  Display statistics for this many devices.

     -w wait	 Wait this many seconds in between displays.  If this option is not specified, ctlstat defaults to a 1 second interval.

EXAMPLES

	   ctlstat -t

     Display total statistics for the system with a one second interval.

	   ctlstat -d -l 5 -C

     Display average DMA time for LUN 5 and omit CPU utilization.

	   ctlstat -n 7 -w 10

     Display statistics for the first 7 LUNs, and display average statistics every 10 seconds.
