79 | |
80 | =head1 DESCRIPTION |
81 | |
82 | The I<dprofpp> command interprets profile data produced by a profiler, such |
83 | as the Devel::DProf profiler. Dprofpp will read the file F<tmon.out> and |
84 | will display the 15 subroutines which are using the most time. By default |
85 | the times for each subroutine are given exclusive of the times of their |
86 | child subroutines. |
87 | |
88 | To profile a Perl script run the perl interpreter with the B<-d> switch. So |
89 | to profile script F<test.pl> with Devel::DProf the following command should |
90 | be used. |
91 | |
92 | $ perl5 -d:DProf test.pl |
93 | |
6fb76034 |
94 | Then run dprofpp to analyze the profile. The output of dprofpp depends |
95 | on the flags to the program and the version of Perl you're using. |
583a019e |
96 | |
97 | $ dprofpp -u |
98 | Total Elapsed Time = 1.67 Seconds |
99 | User Time = 0.61 Seconds |
100 | Exclusive Times |
101 | %Time Seconds #Calls sec/call Name |
102 | 52.4 0.320 2 0.1600 main::foo |
103 | 45.9 0.280 200 0.0014 main::bar |
104 | 0.00 0.000 1 0.0000 DynaLoader::import |
105 | 0.00 0.000 1 0.0000 main::baz |
106 | |
107 | The dprofpp tool can also run the profiler before analyzing the profile |
108 | data. The above two commands can be executed with one dprofpp command. |
109 | |
110 | $ dprofpp -u -p test.pl |
111 | |
112 | Consult L<Devel::DProf/"PROFILE FORMAT"> for a description of the raw profile. |

114 | =head1 OUTPUT |
115 | |
116 | Columns are: |
117 | |
118 | =over 4 |
119 | |
120 | =item %Time |
121 | |
122 | Percentage of time spent in this routine. |
123 | |
124 | =item #Calls |
125 | |
126 | Number of calls to this routine. |
127 | |
128 | =item sec/call |
129 | |
130 | Average number of seconds per call to this routine. |
131 | |
132 | =item Name |
133 | |
134 | Name of routine. |
135 | |
136 | =item CumulS |
137 | |
138 | Time (in seconds) spent in this routine and routines called from it. |
139 | |
140 | =item ExclSec |
141 | |
142 | Time (in seconds) spent in this routine (not including those called |
143 | from it). |
144 | |
145 | =item Csec/c |
146 | |
147 | Average time (in seconds) spent in each call of this routine |
148 | (including those called from it). |
149 | |
150 | =back |
151 | |
583a019e |
152 | =head1 OPTIONS |
153 | |
154 | =over 5 |
155 | |
156 | =item B<-a> |
157 | |
158 | Sort alphabetically by subroutine names. |
159 | |
b331eff5 |
160 | =item B<-d> |
161 | |
162 | Reverse whatever sort is used |
163 | |
583a019e |
164 | =item B<-A> |
165 | |
166 | Count timing for autoloaded subroutine as timing for C<*::AUTOLOAD>. |
167 | Otherwise the time to autoload it is counted as time of the subroutine |
168 | itself (there is no way to separate autoload time from run time). |
169 | |
170 | This is going to be irrelevant with newer Perls. They will inform |
171 | C<Devel::DProf> I<when> the C<AUTOLOAD> switches to actual subroutine, |
172 | so a separate statistics for C<AUTOLOAD> will be collected no matter |
173 | whether this option is set. |
174 | |
175 | =item B<-R> |
176 | |
177 | Count anonymous subroutines defined in the same package separately. |
178 | |
179 | =item B<-E> |
180 | |
181 | (default) Display all subroutine times exclusive of child subroutine times. |
182 | |
183 | =item B<-F> |
184 | |
185 | Force the generation of fake exit timestamps if dprofpp reports that the |
186 | profile is garbled. This is only useful if dprofpp determines that the |
187 | profile is garbled due to missing exit timestamps. You're on your own if |
188 | you do this. Consult the BUGS section. |
189 | |
190 | =item B<-I> |
191 | |
192 | Display all subroutine times inclusive of child subroutine times. |
193 | |
194 | =item B<-l> |
195 | |
196 | Sort by number of calls to the subroutines. This may help identify |
197 | candidates for inlining. |
198 | |
199 | =item B<-O cnt> |
200 | |
201 | Show only I<cnt> subroutines. The default is 15. |
202 | |
203 | =item B<-p script> |
204 | |
205 | Tells dprofpp that it should profile the given script and then interpret its |
206 | profile data. See B<-Q>. |
207 | |
208 | =item B<-Q> |
209 | |
210 | Used with B<-p> to tell dprofpp to quit after profiling the script, without |
211 | interpreting the data. |
212 | |
213 | =item B<-q> |
214 | |
215 | Do not display column headers. |
216 | |
217 | =item B<-r> |
218 | |
219 | Display elapsed real times rather than user+system times. |
220 | |
221 | =item B<-s> |
222 | |
223 | Display system times rather than user+system times. |
224 | |
225 | =item B<-T> |
226 | |
227 | Display subroutine call tree to stdout. Subroutine statistics are |
228 | not displayed. |
229 | |
230 | =item B<-t> |
231 | |
232 | Display subroutine call tree to stdout. Subroutine statistics are not |
233 | displayed. When a function is called multiple consecutive times at the same |
234 | calling level then it is displayed once with a repeat count. |
235 | |
236 | =item B<-S> |
237 | |
c1d47b76 |
238 | Display I<merged> subroutine call tree to stdout. Statistics are |
583a019e |
239 | displayed for each branch of the tree. |
240 | |
241 | When a function is called multiple (I<not necessarily consecutive>) |
242 | times in the same branch then all these calls go into one branch of |
243 | the next level. A repeat count is output together with combined |
244 | inclusive, exclusive and kids time. |
245 | |
246 | Branches are sorted w.r.t. inclusive time. |
247 | |
248 | =item B<-U> |
249 | |
250 | Do not sort. Display in the order found in the raw profile. |
251 | |
252 | =item B<-u> |
253 | |
254 | Display user times rather than user+system times. |
255 | |
256 | =item B<-V> |
257 | |
258 | Print dprofpp's version number and exit. If a raw profile is found then its |
259 | XS_VERSION variable will be displayed, too. |
260 | |
261 | =item B<-v> |
262 | |
263 | Sort by average time spent in subroutines during each call. This may help |
264 | identify candidates for inlining. |
265 | |
266 | =item B<-z> |
267 | |
268 | (default) Sort by amount of user+system time used. The first few lines |
269 | should show you which subroutines are using the most time. |
270 | |
271 | =item B<-g> C<subroutine> |
272 | |
273 | Ignore subroutines except C<subroutine> and whatever is called from it. |
274 | |
b331eff5 |
275 | =item B<-G> <regexp> |
276 | |
277 | Aggregate "Group" all calls matching the pattern together. |
278 | For example this can be used to group all calls of a set of packages |
279 | |
280 | -G "(package1::)|(package2::)|(package3::)" |
281 | |
282 | or to group subroutines by name: |
283 | |
284 | -G "getNum" |
285 | |
286 | =item B<-P> |
287 | |
288 | Used with -G to aggregate "Pull" together all calls that did not match -G. |
289 | |
290 | =item B<-f> <regexp> |
291 | |
292 | Filter all calls matching the pattern. |
293 | |
583a019e |
294 | =back |
295 | |
296 | =head1 ENVIRONMENT |
297 | |
298 | The environment variable B<DPROFPP_OPTS> can be set to a string containing |
299 | options for dprofpp. You might use this if you prefer B<-I> over B<-E> or |
300 | if you want B<-F> on all the time. |
301 | |
302 | This was added fairly lazily, so there are some undesirable side effects. |
303 | Options on the commandline should override options in DPROFPP_OPTS--but |
304 | don't count on that in this version. |
305 | |
306 | =head1 BUGS |
307 | |
308 | Applications which call _exit() or exec() from within a subroutine |
309 | will leave an incomplete profile. See the B<-F> option. |
310 | |
311 | Any bugs in Devel::DProf, or any profiler generating the profile data, could |
312 | be visible here. See L<Devel::DProf/BUGS>. |
313 | |
314 | Mail bug reports and feature requests to the perl5-porters mailing list at |
315 | F<E<lt>perl5-porters@perl.orgE<gt>>. Bug reports should include the |
316 | output of the B<-V> option. |
