77 | ||
78 | dprofpp B<-V> [profile] | |
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 | |
b65c400d | 84 | display the 15 subroutines which are using the most time. By default |
583a019e GS |
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 | |
b65c400d | 89 | to profile script F<test.pl> with Devel::DProf use the following: |
583a019e GS |
90 | |
91 | $ perl5 -d:DProf test.pl | |
92 | ||
6fb76034 GS |
93 | Then run dprofpp to analyze the profile. The output of dprofpp depends |
94 | on the flags to the program and the version of Perl you're using. | |
583a019e GS |
95 | |
96 | $ dprofpp -u | |
97 | Total Elapsed Time = 1.67 Seconds | |
98 | User Time = 0.61 Seconds | |
99 | Exclusive Times | |
100 | %Time Seconds #Calls sec/call Name | |
101 | 52.4 0.320 2 0.1600 main::foo | |
102 | 45.9 0.280 200 0.0014 main::bar | |
103 | 0.00 0.000 1 0.0000 DynaLoader::import | |
104 | 0.00 0.000 1 0.0000 main::baz | |
105 | ||
106 | The dprofpp tool can also run the profiler before analyzing the profile | |
107 | data. The above two commands can be executed with one dprofpp command. | |
108 | ||
109 | $ dprofpp -u -p test.pl | |
110 | ||
111 | Consult L<Devel::DProf/"PROFILE FORMAT"> for a description of the raw profile. | |

114 | ||
115 | Columns are: | |
116 | ||
117 | =over 4 | |
118 | ||
119 | =item %Time | |
120 | ||
121 | Percentage of time spent in this routine. | |
122 | ||
123 | =item #Calls | |
124 | ||
125 | Number of calls to this routine. | |
126 | ||
127 | =item sec/call | |
128 | ||
129 | Average number of seconds per call to this routine. | |
130 | ||
131 | =item Name | |
132 | ||
133 | Name of routine. | |
134 | ||
135 | =item CumulS | |
136 | ||
137 | Time (in seconds) spent in this routine and routines called from it. | |
138 | ||
139 | =item ExclSec | |
140 | ||
141 | Time (in seconds) spent in this routine (not including those called | |
142 | from it). | |
143 | ||
144 | =item Csec/c | |
145 | ||
146 | Average time (in seconds) spent in each call of this routine | |
147 | (including those called from it). | |
148 | ||
149 | =back | |

151 | =head1 OPTIONS |
152 | ||
153 | =over 5 | |
154 | ||
155 | =item B<-a> | |
156 | ||
157 | Sort alphabetically by subroutine names. | |
158 | ||
b331eff5 CE |
159 | =item B<-d> |
160 | ||
161 | Reverse whatever sort is used | |
162 | ||
583a019e GS |
163 | =item B<-A> |
164 | ||
165 | Count timing for autoloaded subroutine as timing for C<*::AUTOLOAD>. | |
166 | Otherwise the time to autoload it is counted as time of the subroutine | |
167 | itself (there is no way to separate autoload time from run time). | |
168 | ||
169 | This is going to be irrelevant with newer Perls. They will inform | |
170 | C<Devel::DProf> I<when> the C<AUTOLOAD> switches to actual subroutine, | |
171 | so a separate statistics for C<AUTOLOAD> will be collected no matter | |
172 | whether this option is set. | |
173 | ||
174 | =item B<-R> | |
175 | ||
176 | Count anonymous subroutines defined in the same package separately. | |
177 | ||
178 | =item B<-E> | |
179 | ||
180 | (default) Display all subroutine times exclusive of child subroutine times. | |
181 | ||
182 | =item B<-F> | |
183 | ||
184 | Force the generation of fake exit timestamps if dprofpp reports that the | |
185 | profile is garbled. This is only useful if dprofpp determines that the | |
186 | profile is garbled due to missing exit timestamps. You're on your own if | |
187 | you do this. Consult the BUGS section. | |
188 | ||
189 | =item B<-I> | |
190 | ||
191 | Display all subroutine times inclusive of child subroutine times. | |
192 | ||
193 | =item B<-l> | |
194 | ||
195 | Sort by number of calls to the subroutines. This may help identify | |
196 | candidates for inlining. | |
197 | ||
198 | =item B<-O cnt> | |
199 | ||
200 | Show only I<cnt> subroutines. The default is 15. | |
201 | ||
202 | =item B<-p script> | |
203 | ||
204 | Tells dprofpp that it should profile the given script and then interpret its | |
205 | profile data. See B<-Q>. | |
206 | ||
207 | =item B<-Q> | |
208 | ||
209 | Used with B<-p> to tell dprofpp to quit after profiling the script, without | |
210 | interpreting the data. | |
211 | ||
212 | =item B<-q> | |
213 | ||
214 | Do not display column headers. | |
215 | ||
216 | =item B<-r> | |
217 | ||
218 | Display elapsed real times rather than user+system times. | |
219 | ||
220 | =item B<-s> | |
221 | ||
222 | Display system times rather than user+system times. | |
223 | ||
224 | =item B<-T> | |
225 | ||
226 | Display subroutine call tree to stdout. Subroutine statistics are | |
227 | not displayed. | |
228 | ||
229 | =item B<-t> | |
230 | ||
231 | Display subroutine call tree to stdout. Subroutine statistics are not | |
232 | displayed. When a function is called multiple consecutive times at the same | |
233 | calling level then it is displayed once with a repeat count. | |
234 | ||
235 | =item B<-S> | |
236 | ||
c1d47b76 | 237 | Display I<merged> subroutine call tree to stdout. Statistics are |
583a019e GS |
238 | displayed for each branch of the tree. |
239 | ||
240 | When a function is called multiple (I<not necessarily consecutive>) | |
241 | times in the same branch then all these calls go into one branch of | |
242 | the next level. A repeat count is output together with combined | |
243 | inclusive, exclusive and kids time. | |
244 | ||
b65c400d | 245 | Branches are sorted with regard to inclusive time. |
583a019e GS |
246 | |
247 | =item B<-U> | |
248 | ||
249 | Do not sort. Display in the order found in the raw profile. | |
250 | ||
251 | =item B<-u> | |
252 | ||
253 | Display user times rather than user+system times. | |
254 | ||
255 | =item B<-V> | |
256 | ||
257 | Print dprofpp's version number and exit. If a raw profile is found then its | |
258 | XS_VERSION variable will be displayed, too. | |
259 | ||
260 | =item B<-v> | |
261 | ||
262 | Sort by average time spent in subroutines during each call. This may help | |
263 | identify candidates for inlining. | |
264 | ||
265 | =item B<-z> | |
266 | ||
267 | (default) Sort by amount of user+system time used. The first few lines | |
268 | should show you which subroutines are using the most time. | |
269 | ||
270 | =item B<-g> C<subroutine> | |
271 | ||
272 | Ignore subroutines except C<subroutine> and whatever is called from it. | |
273 | ||
b331eff5 CE |
274 | =item B<-G> <regexp> |
275 | ||
276 | Aggregate "Group" all calls matching the pattern together. | |
277 | For example this can be used to group all calls of a set of packages | |
278 | ||
279 | -G "(package1::)|(package2::)|(package3::)" | |
280 | ||
281 | or to group subroutines by name: | |
282 | ||
283 | -G "getNum" | |
284 | ||
285 | =item B<-P> | |
286 | ||
b65c400d | 287 | Used with -G to aggregate "Pull" together all calls that did not match -G. |
b331eff5 CE |
288 | |
289 | =item B<-f> <regexp> | |
290 | ||
291 | Filter all calls matching the pattern. | |
292 | ||
b65c400d AL |
293 | =item B<-h> |
294 | ||
295 | Display brief help and exit. | |
296 | ||
297 | =item B<-H> | |
298 | ||
299 | Display long help and exit. | |
300 | ||

302 | ||
303 | =head1 ENVIRONMENT | |
304 | ||
305 | The environment variable B<DPROFPP_OPTS> can be set to a string containing | |
306 | options for dprofpp. You might use this if you prefer B<-I> over B<-E> or | |
307 | if you want B<-F> on all the time. | |
308 | ||
309 | This was added fairly lazily, so there are some undesirable side effects. | |
310 | Options on the commandline should override options in DPROFPP_OPTS--but | |
311 | don't count on that in this version. | |
312 | ||
313 | =head1 BUGS | |
314 | ||
315 | Applications which call _exit() or exec() from within a subroutine | |
316 | will leave an incomplete profile. See the B<-F> option. | |
317 | ||
318 | Any bugs in Devel::DProf, or any profiler generating the profile data, could | |
319 | be visible here. See L<Devel::DProf/BUGS>. | |
320 | ||
321 | Mail bug reports and feature requests to the perl5-porters mailing list at | |
322 | F<E<lt>perl5-porters@perl.orgE<gt>>. Bug reports should include the | |
323 | output of the B<-V> option. | |
