18 The sadf command is used for displaying the contents of data files cre‐
19 ated by the sar(1) command. But unlike sar, sadf can write its data in
20 many different formats (CSV, XML, etc.) The default format is one that
21 can easily be handled by pattern processing commands like awk (see op‐
22 tion -p). The sadf command can also be used to draw graphs for the var‐
23 ious activities collected by sar and display them as SVG (Scalable Vec‐
24 tor Graphics) graphics in your web browser (see option -g).
25 The sadf command extracts and writes to standard output records saved
27 in the datafile file. This file must have been created by a version of
28 sar which is compatible with that of sadf. If datafile is omitted, sadf
29 uses the standard system activity daily data file. It is also possible
30 to enter -1, -2 etc. as an argument to sadf to display data of that
31 days ago. For example, -1 will point at the standard system activity
32 file of yesterday.
33 The standard system activity daily data file is named saDD or saYYYYM‐
35 MDD, where YYYY stands for the current year, MM for the current month
36 and DD for the current day. sadf will look for the most recent of saDD
37 and saYYYYMMDD, and use it. By default it is located in the /var/log/sa
38 directory. Yet it is possible to specify an alternate location for it:
39 If datafile is a directory (instead of a plain file) then it will be
40 considered as the directory where the standard system activity daily
41 data file is located.
42 The interval and count parameters are used to tell sadf to select count
44 records at interval seconds apart. If the count parameter is not set,
45 then all the records saved in the data file will be displayed.
46 All the activity flags of sar may be entered on the command line to in‐
48 dicate which activities are to be reported. Before specifying them, put
49 a pair of dashes (--) on the command line in order not to confuse the
50 flags with those of sadf. Not specifying any flags selects only CPU
51 activity.
52
55 -C Tell sadf to display comments present in file.
56 -c Convert an old system activity binary datafile (version 9.1.6
58 and later) to current up-to-date format. Use the following syn‐
59 tax:
60 sadf -c old_datafile > new_datafile
62 Conversion can be controlled using option -O (see below).
64 -d Print the contents of the data file in a format that can easily
66 be ingested by a relational database system. The output consists
67 of fields separated by a semicolon. Each record contains the
68 hostname of the host where the file was created, the interval
69 value (or -1 if not applicable), the timestamp in a form easily
70 acceptable by most databases, and additional semicolon separated
71 data fields as specified by sar_options command line options.
72 Note that timestamp output can be controlled by options -T, -t
73 and -U.
74 --dev=dev_list
76 Specify the block devices for which statistics are to be dis‐
77 played by sadf. dev_list is a list of comma-separated device
78 names. Useful with option -d from sar.
79 -e [ hh:mm[:ss] ]
81 Set the ending time of the report. The default ending time is
82 18:00:00. Hours must be given in 24-hour format.
83 --fs=fs_list
85 Specify the filesystems for which statistics are to be displayed
86 by sadf. fs_list is a list of comma-separated filesystem names
87 or mountpoints. Useful with option -F from sar.
88 -g Print the contents of the data file in SVG (Scalable Vector
90 Graphics) format. This option enables you to display some fancy
91 graphs in your web browser. Use the following syntax:
92 sadf -g your_datafile [ -- sar_options ] > output.svg
94 and open the resulting SVG file in your favorite web browser.
96 Output can be controlled using option -O (see below).
97 -H Display only the header of the report (when applicable). If no
99 format has been specified, then the header data (metadata) of
100 the data file are displayed.
101 -h When used in conjunction with option -d, all activities will be
103 displayed horizontally on a single line.
104 --iface=iface_list
106 Specify the network interfaces for which statistics are to be
107 displayed by sadf. iface_list is a list of comma-separated in‐
108 terface names. Useful with options -n DEV and -n EDEV from sar.
109 -j Print the contents of the data file in JSON (JavaScript Object
111 Notation) format. Timestamps can be controlled by options -T and
112 -t.
113 -l Export the contents of the data file to a PCP (Performance Co-
115 Pilot) archive. The name of the archive can be specified using
116 the keyword pcparchive= with option -O.
117 -O opts[,...]
119 Use the specified options to control the output of sadf. The
120 following options are used to control SVG output displayed by
121 sadf -g:
122 autoscale
124 Draw all the graphs of a given view as large as possible
125 based on current view's scale. To do this, a factor (10,
126 100, 1000...) is used to enlarge the graph drawing. This
127 option may be interesting when several graphs are drawn
128 on the same view, some with only very small values, and
129 others with high ones, the latter making the former
130 hardly visible.
131 bwcol Use a black and white palette to draw the graphs.
133 customcol
135 Use a customizable color palette instead of the default
136 one to draw the graphs. See environment variable S_COL‐
137 ORS_PALETTE below to know how to customize that palette.
138 debug Add helpful comments in SVG output file.
140 height=value
142 Set SVG canvas height to value.
143 oneday Display graphs data over a period of 24 hours. Note that
145 hours are still printed in UTC by default: You should use
146 option -T to print them in local time and get a time win‐
147 dow starting from midnight.
148 packed Group all views from the same activity (and for the same
150 device) on the same row.
151 showidle
153 Also display %idle state in graphs for CPU statistics.
154 showinfo
156 Display additional information (such as the date and the
157 host name) on each view.
158 showtoc
160 Add a table of contents at the beginning of the SVG out‐
161 put, consisting of links pointing at the first graph of
162 each activity.
163 skipempty
165 Do not display views where all graphs have only zero val‐
166 ues.
167 The following option may be used when converting an old system
169 activity binary datafile to current up-to-date format:
170 hz=value
172 Specify the number of ticks per second for the machine
173 where the old datafile has been created.
174 The following option may be used when data are exported to a PCP
176 archive:
177 pcparchive=name
179 Specify the name of the PCP archive to create.
180 The following option is used to control raw output displayed by
182 sadf -r:
183 debug Display additional information, mainly useful for debug‐
185 ging purpose.
186 -P { cpu_list | ALL }
188 Tell sadf that processor dependent statistics are to be reported
189 only for the specified processor or processors. cpu_list is a
190 list of comma-separated values or range of values (e.g.,
191 0,2,4-7,12-). Note that processor 0 is the first processor, and
192 processor all is the global average among all processors. Speci‐
193 fying the ALL keyword reports statistics for each individual
194 processor, and globally for all processors.
195 -p Print the contents of the data file in a format that can easily
197 be handled by pattern processing commands like awk. The output
198 consists of fields separated by a tab. Each record contains the
199 hostname of the host where the file was created, the interval
200 value (or -1 if not applicable), the timestamp, the device name
201 (or - if not applicable), the field name and its value. Note
202 that timestamp output can be controlled by options -T, -t and
203 -U.
204 -r Print the raw contents of the data file. With this format, the
206 values for all the counters are displayed as read from the ker‐
207 nel, which means e.g., that no average values are calculated
208 over the elapsed time interval. Output can be controlled using
209 option -O (see above).
210 -s [ hh:mm[:ss] ]
212 Set the starting time of the data, causing the sadf command to
213 extract records time-tagged at, or following, the time speci‐
214 fied. The default starting time is 08:00:00. Hours must be
215 given in 24-hour format.
216 -T Display timestamp in local time instead of UTC (Coordinated Uni‐
218 versal Time).
219 -t Display timestamp in the original local time of the data file
221 creator instead of UTC (Coordinated Universal Time).
222 -U Display timestamp (UTC - Coordinated Universal Time) in seconds
224 from the epoch.
225 -V Print version number then exit.
227 -x Print the contents of the data file in XML format. Timestamps
229 can be controlled by options -T and -t. The corresponding DTD
230 (Document Type Definition) and XML Schema are included in the
231 sysstat source package. They are also available at http://pages‐
232 perso-orange.fr/sebastien.godard/download.html.
233
236 The sadf command takes into account the following environment vari‐
237 ables:
238 S_COLORS_PALETTE
240 Specify the colors used by sadf -g to render the SVG output.
241 This environment variable is taken into account only when the
242 custom color palette has been selected with the option customcol
243 (see option -O). Its value is a colon-separated list of capa‐
244 bilities associated with six-digit, three-byte hexadecimal num‐
245 bers (hex triplets) representing colors that defaults to
246 0=000000:1=1a1aff:2=1affb2:3=b21aff:
248 4=1ab2ff:5=ff1a1a:6=ffb31a:7=b2ff1a:
249 8=efefef:9=000000:A=1a1aff:B=1affb2:
250 C=b21aff:D=1ab2ff:E=ff1a1a:F=ffb31a:
251 G=bebebe:H=000000:I=000000:K=ffffff:
252 L=000000:T=000000:W=000000:X=000000
253 Capabilities consisting of an hexadecimal digit (0 through F)
255 are used to specify the first sixteen colors in the palette
256 (these colors are used to draw the graphs), e.g., 3=ffffff would
257 indicate that the third color in the palette is white
258 (0xffffff).
259 Other capabilities are:
260 G= Specify the color used to draw the grid lines.
262 H= Specify the color used to display the report header.
264 I= Specify the color used to display additional information
266 (e.g., date, hostname...)
267 K= Specify the color used for the graphs background.
269 L= Specify the default color (which is for example used to
271 display the table of contents).
272 T= Specify the color used to display the graphs title.
274 W= Specify the color used to display warning and error mes‐
276 sages.
277 X= Specify the color used to draw the axes and display the
279 graduations.
280 S_TIME_DEF_TIME
282 If this variable exists and its value is UTC then sadf will use
283 UTC time instead of local time to determine the current daily
284 data file located in the /var/log/sa directory.
285
288 sadf -d /var/log/sa/sa21 -- -r -n DEV
289 Extract memory and network statistics from system activity file
290 sa21, and display them in a format that can be ingested by a
291 database.
292 sadf -p -P 1
294 Extract CPU statistics for processor 1 (the second processor)
295 from current daily data file, and display them in a format that
296 can easily be handled by a pattern processing command.
297
300 SVG output (as created by option -g) is fully compliant with SVG 1.1
301 standard. Graphics have been successfully displayed in various web
302 browsers, including Firefox, Chrome and Opera. Yet SVG rendering is
303 broken on Microsoft browsers (tested on Internet Explorer 11 and Edge
304 13.1): So please don't use them.
305
308 /var/log/sa/saDD
309 /var/log/sa/saYYYYMMDD
310 The standard system activity daily data files and their default
311 location. YYYY stands for the current year, MM for the current
312 month and DD for the current day.
