SADF(1) Linux User's Manual SADF(1)NAMEsadf - Display data collected by sar in multiple formats.
SYNOPSISsadf [ -d | -D | -H | -p | -x ] [ -h ] [ -t ] [ -V ] [ -P { cpu [,...]
| ALL } ] [ -s [ hh:mm:ss ] ] [ -e [ hh:mm:ss ] ] [ -- sar_options ] [
interval [ count ] ] [ datafile ]
DESCRIPTION
The sadf command is used for displaying the contents of data files cre‐
ated by the sar(1) command. But unlike sar, sadf can write its data in
many different formats (CSV, XML, etc.) The default format is one that
can easily be handled by pattern processing commands like awk (see
option -p).
The sadf command extracts and writes to standard output records saved
in the datafile file. This file must have been created by a version of
sar which is compatible with that of sadf. If datafile is omitted,
sadf uses the standard system activity file, the /var/log/sa/sadd file,
where the dd parameter indicates the current day.
The interval and count parameters are used to tell sadf to select count
records at interval seconds apart. If the count parameter is not set,
then all the records saved in the data file will be displayed.
All the activity flags of sar may be entered on the command line to
indicate which activities are to be reported. Before specifying them,
put a pair of dashes (--) on the command line in order not to confuse
the flags with those of sadf. Not specifying any flags selects only
CPU activity.
OPTIONS-D This option is equivalent to option -d below, except that the
timestamp is always expressed in seconds since the epoch
(00:00:00 UTC 01/01/1970).
-d Print the contents of the data file in a format that can easily
be ingested by a relational database system. The output consists
of fields separated by a semicolon. Each record contains the
hostname of the host where the file was created, the interval
value (or -1 if not applicable), the timestamp in a form easily
acceptable by most databases, and additional semicolon separated
data fields as specified by sar_options command line options.
Note that the timestamp is displayed in UTC (Coordinated Univer‐
sal Time) unless option -t is used. In this latter case, the
timestamp is displayed in local time.
-e [ hh:mm:ss ]
Set the ending time of the report, given in local time. The
default ending time is 18:00:00. Hours must be given in 24-hour
format. This option is ignored when option -x is used.
-h When used in conjunction with option -d or -D, all activities
will be displayed horizontally on a single line.
-H Display the header of the data file.
-P { cpu [,...] | ALL }
Tell sadf that processor dependent statistics are to be reported
only for the specified processor or processors. Specifying the
ALL keyword reports statistics for each individual processor,
and globally for all processors. Note that processor 0 is the
first processor.
-p Print the contents of the data file in a format that can easily
be handled by pattern processing commands like awk. The output
consists of fields separated by a tab. Each record contains the
hostname of the host where the file was created, the interval
value (or -1 if not applicable), the timestamp (UTC value -
Coordinated Universal Time) in seconds from the epoch, the
device name (or - if not applicable), the field name and its
value.
-s [ hh:mm:ss ]
Set the starting time of the data (given in local time), causing
the sadf command to extract records time-tagged at, or follow‐
ing, the time specified. The default starting time is 08:00:00.
Hours must be given in 24-hour format. This option is ignored
when option -x is used.
-t When this option is used together with options -d or -x, the
timestamp is displayed in local time instead of UTC (Coordinated
Universal Time). This option is ignored when options -p or -D
are used.
-V Print version number then exit.
-x Print the contents of the data file in XML format. Timestamps
are displayed in UTC (Coordinated Universal Time) unless option
-t is used, in which case they are displayed in local time. The
corresponding DTD (Document Type Definition) and XML Schema are
included in the sysstat source package. They are also available
at http://pagesperso-orange.fr/sebastien.godard/download.html
ENVIRONMENT
The sadf command takes into account the following environment variable:
S_TIME_DEF_TIME
If this variable exists and its value is UTC then sadf will use
UTC time instead of local time to determine the current daily
data file located in the /var/log/sa directory.
EXAMPLESsadf-d /var/log/sa/sa21 -- -r -n DEV
Extract memory, swap space and network statistics from system
activity file 'sa21', and display them in a format that can be
ingested by a database.
sadf-p -P 1
Extract CPU statistics for processor 1 (the second processor)
from current daily data file, and display them in a format that
can easily be handled by a pattern processing command.
FILES
/var/log/sa/sadd
Indicate the daily data file, where the dd parameter is a number
representing the day of the month.
