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 |
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 |
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. |

105 | =head1 OUTPUT |
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 |
142 | |
583a019e |
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. |
