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 GS |
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 GS |
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. | |

116 | Columns are: | |
117 | ||
118 | =over 4 | |

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 | ||

152 | =head1 OPTIONS |
153 | ||
154 | =over 5 | |
155 | ||
156 | =item B<-a> | |
157 | ||
158 | Sort alphabetically by subroutine names. | |
159 | ||
b331eff5 CE |
160 | =item B<-d> |
161 | ||
162 | Reverse whatever sort is used | |
163 | ||
583a019e GS |
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 GS |
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 CE |
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 GS |
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. | |
