57 | dprofpp - display perl profile data | |
58 | ||
59 | =head1 SYNOPSIS | |
60 | ||
61 | dprofpp [B<-a>|B<-z>|B<-l>|B<-v>|B<-U>] [B<-s>|B<-r>|B<-u>] [B<-q>] [B<-F>] [B<-I|-E>] [B<-O cnt>] [B<-A>] [B<-R>] [B<-S>] [B<-g subroutine>] [profile] | |
62 | ||
63 | dprofpp B<-T> [B<-F>] [B<-g subroutine>] [profile] | |
64 | ||
65 | dprofpp B<-t> [B<-F>] [B<-g subroutine>] [profile] | |
66 | ||
67 | dprofpp B<-p script> [B<-Q>] [other opts] | |
68 | ||
69 | dprofpp B<-V> [profile] | |
70 | ||
71 | =head1 DESCRIPTION | |
72 | ||
73 | The I<dprofpp> command interprets profile data produced by a profiler, such | |
74 | as the Devel::DProf profiler. Dprofpp will read the file F<tmon.out> and | |
75 | will display the 15 subroutines which are using the most time. By default | |
76 | the times for each subroutine are given exclusive of the times of their | |
77 | child subroutines. | |
78 | ||
79 | To profile a Perl script run the perl interpreter with the B<-d> switch. So | |
80 | to profile script F<test.pl> with Devel::DProf the following command should | |
81 | be used. | |
82 | ||
83 | $ perl5 -d:DProf test.pl | |
84 | ||
6fb76034 GS |
85 | Then run dprofpp to analyze the profile. The output of dprofpp depends |
86 | on the flags to the program and the version of Perl you're using. | |
583a019e GS |
87 | |
88 | $ dprofpp -u | |
89 | Total Elapsed Time = 1.67 Seconds | |
90 | User Time = 0.61 Seconds | |
91 | Exclusive Times | |
92 | %Time Seconds #Calls sec/call Name | |
93 | 52.4 0.320 2 0.1600 main::foo | |
94 | 45.9 0.280 200 0.0014 main::bar | |
95 | 0.00 0.000 1 0.0000 DynaLoader::import | |
96 | 0.00 0.000 1 0.0000 main::baz | |
97 | ||
98 | The dprofpp tool can also run the profiler before analyzing the profile | |
99 | data. The above two commands can be executed with one dprofpp command. | |
100 | ||
101 | $ dprofpp -u -p test.pl | |
102 | ||
103 | Consult L<Devel::DProf/"PROFILE FORMAT"> for a description of the raw profile. | |

106 | ||
107 | Columns are: | |
108 | ||
109 | =over 4 | |
110 | ||
111 | =item %Time | |
112 | ||
113 | Percentage of time spent in this routine. | |
114 | ||
115 | =item #Calls | |
116 | ||
117 | Number of calls to this routine. | |
118 | ||
119 | =item sec/call | |
120 | ||
121 | Average number of seconds per call to this routine. | |
122 | ||
123 | =item Name | |
124 | ||
125 | Name of routine. | |
126 | ||
127 | =item CumulS | |
128 | ||
129 | Time (in seconds) spent in this routine and routines called from it. | |
130 | ||
131 | =item ExclSec | |
132 | ||
133 | Time (in seconds) spent in this routine (not including those called | |
134 | from it). | |
135 | ||
136 | =item Csec/c | |
137 | ||
138 | Average time (in seconds) spent in each call of this routine | |
139 | (including those called from it). | |
140 | ||
141 | =back | |

583a019e GS |
143 | =head1 OPTIONS |
144 | ||
145 | =over 5 | |
146 | ||
147 | =item B<-a> | |
148 | ||
149 | Sort alphabetically by subroutine names. | |
150 | ||
151 | =item B<-A> | |
152 | ||
153 | Count timing for autoloaded subroutine as timing for C<*::AUTOLOAD>. | |
154 | Otherwise the time to autoload it is counted as time of the subroutine | |
155 | itself (there is no way to separate autoload time from run time). | |
156 | ||
157 | This is going to be irrelevant with newer Perls. They will inform | |
158 | C<Devel::DProf> I<when> the C<AUTOLOAD> switches to actual subroutine, | |
159 | so a separate statistics for C<AUTOLOAD> will be collected no matter | |
160 | whether this option is set. | |
161 | ||
162 | =item B<-R> | |
163 | ||
164 | Count anonymous subroutines defined in the same package separately. | |
165 | ||
166 | =item B<-E> | |
167 | ||
168 | (default) Display all subroutine times exclusive of child subroutine times. | |
169 | ||
170 | =item B<-F> | |
171 | ||
172 | Force the generation of fake exit timestamps if dprofpp reports that the | |
173 | profile is garbled. This is only useful if dprofpp determines that the | |
174 | profile is garbled due to missing exit timestamps. You're on your own if | |
175 | you do this. Consult the BUGS section. | |
176 | ||
177 | =item B<-I> | |
178 | ||
179 | Display all subroutine times inclusive of child subroutine times. | |
180 | ||
181 | =item B<-l> | |
182 | ||
183 | Sort by number of calls to the subroutines. This may help identify | |
184 | candidates for inlining. | |
185 | ||
186 | =item B<-O cnt> | |
187 | ||
188 | Show only I<cnt> subroutines. The default is 15. | |
189 | ||
190 | =item B<-p script> | |
191 | ||
192 | Tells dprofpp that it should profile the given script and then interpret its | |
193 | profile data. See B<-Q>. | |
194 | ||
195 | =item B<-Q> | |
196 | ||
197 | Used with B<-p> to tell dprofpp to quit after profiling the script, without | |
198 | interpreting the data. | |
199 | ||
200 | =item B<-q> | |
201 | ||
202 | Do not display column headers. | |
203 | ||
204 | =item B<-r> | |
205 | ||
206 | Display elapsed real times rather than user+system times. | |
207 | ||
208 | =item B<-s> | |
209 | ||
210 | Display system times rather than user+system times. | |
211 | ||
212 | =item B<-T> | |
213 | ||
214 | Display subroutine call tree to stdout. Subroutine statistics are | |
215 | not displayed. | |
216 | ||
217 | =item B<-t> | |
218 | ||
219 | Display subroutine call tree to stdout. Subroutine statistics are not | |
220 | displayed. When a function is called multiple consecutive times at the same | |
221 | calling level then it is displayed once with a repeat count. | |
222 | ||
223 | =item B<-S> | |
224 | ||
225 | Display I<merged> subroutine call tree to stdout. Statistics is | |
226 | displayed for each branch of the tree. | |
227 | ||
228 | When a function is called multiple (I<not necessarily consecutive>) | |
229 | times in the same branch then all these calls go into one branch of | |
230 | the next level. A repeat count is output together with combined | |
231 | inclusive, exclusive and kids time. | |
232 | ||
233 | Branches are sorted w.r.t. inclusive time. | |
234 | ||
235 | =item B<-U> | |
236 | ||
237 | Do not sort. Display in the order found in the raw profile. | |
238 | ||
239 | =item B<-u> | |
240 | ||
241 | Display user times rather than user+system times. | |
242 | ||
243 | =item B<-V> | |
244 | ||
245 | Print dprofpp's version number and exit. If a raw profile is found then its | |
246 | XS_VERSION variable will be displayed, too. | |
247 | ||
248 | =item B<-v> | |
249 | ||
250 | Sort by average time spent in subroutines during each call. This may help | |
251 | identify candidates for inlining. | |
252 | ||
253 | =item B<-z> | |
254 | ||
255 | (default) Sort by amount of user+system time used. The first few lines | |
256 | should show you which subroutines are using the most time. | |
257 | ||
258 | =item B<-g> C<subroutine> | |
259 | ||
260 | Ignore subroutines except C<subroutine> and whatever is called from it. | |
261 | ||
262 | =back | |
263 | ||
264 | =head1 ENVIRONMENT | |
265 | ||
266 | The environment variable B<DPROFPP_OPTS> can be set to a string containing | |
267 | options for dprofpp. You might use this if you prefer B<-I> over B<-E> or | |
268 | if you want B<-F> on all the time. | |
269 | ||
270 | This was added fairly lazily, so there are some undesirable side effects. | |
271 | Options on the commandline should override options in DPROFPP_OPTS--but | |
272 | don't count on that in this version. | |
273 | ||
274 | =head1 BUGS | |
275 | ||
276 | Applications which call _exit() or exec() from within a subroutine | |
277 | will leave an incomplete profile. See the B<-F> option. | |
278 | ||
279 | Any bugs in Devel::DProf, or any profiler generating the profile data, could | |
280 | be visible here. See L<Devel::DProf/BUGS>. | |
281 | ||
282 | Mail bug reports and feature requests to the perl5-porters mailing list at | |
283 | F<E<lt>perl5-porters@perl.orgE<gt>>. Bug reports should include the | |
284 | output of the B<-V> option. | |
