2832c235 TH |
268 | |
269 | =head1 REQUIREMENTS | |
270 | ||
edd250f2 | 271 | See L<doc/README>. |
2832c235 TH |
272 | |
273 | =head1 DESCRIPTION | |
274 | ||
275 | This script create reports on newsgroup usage (number of postings per | |
276 | group per month) taken from result tables created by | |
edd250f2 | 277 | B<gatherstats.pl>. |
2832c235 | 278 | |
edd250f2 | 279 | =head2 Features and options |
2832c235 | 280 | |
edd250f2 | 281 | =head3 Time period and newsgroups |
2832c235 | 282 | |
edd250f2 TH |
283 | The time period to act on defaults to last month; you can assign another |
284 | time period or a single month (or drop all time constraints) via the | |
285 | B<--month> option (see below). | |
2832c235 | 286 | |
edd250f2 TH |
287 | B<groupstats> will process all newsgroups by default; you can limit |
288 | processing to only some newsgroups by supplying a list of those groups via | |
289 | B<--newsgroups> option (see below). You can include hierarchy levels in | |
290 | the output by adding the B<--sums> switch (see below). Optionally | |
291 | newsgroups not present in a checkgroups file can be excluded from output, | |
292 | sse B<--checkgroups> below. | |
293 | ||
294 | =head3 Report type | |
295 | ||
296 | You can choose between different B<--report> types: postings per month, | |
297 | average postings per month or all postings summed up; for details, see | |
298 | below. | |
299 | ||
300 | =head3 Upper and lower boundaries | |
301 | ||
302 | Furthermore you can set an upper and/or lower boundary to exclude some | |
303 | results from output via the B<--lower> and B<--upper> options, | |
304 | respectively. By default, all newsgroups with more and/or less postings | |
305 | per month will be excluded from the result set (i.e. not shown and not | |
306 | considered for average and sum reports). You can change the meaning of | |
307 | those boundaries with the B<--boundary> option. For details, please see | |
308 | below. | |
309 | ||
310 | =head3 Sorting and formatting the output | |
311 | ||
312 | By default, all results are grouped by month; you can group results by | |
313 | newsgroup instead via the B<--groupy-by> option. Within those groups, the | |
314 | list of newsgroups (or months) is sorted alphabetically (or | |
315 | chronologically, respectively) ascending. You can change that order (and | |
316 | sort by number of postings) with the B<--order-by> option. For details and | |
317 | exceptions, please see below. | |
318 | ||
319 | The results will be formatted as a kind of table; you can change the | |
320 | output format to a simple list or just a list of newsgroups and number of | |
321 | postings with the B<--format> option. Captions will be added by means of | |
322 | the B<--caption> option; all comments (and captions) can be supressed by | |
323 | using B<--nocomments>. | |
324 | ||
325 | Last but not least you can redirect all output to a number of files, e.g. | |
326 | one for each month, by submitting the B<--filetemplate> option, see below. | |
327 | Captions and comments are automatically disabled in this case. | |
2832c235 TH |
328 | |
329 | =head2 Configuration | |
330 | ||
f2ddfd8a | 331 | B<groupstats> will read its configuration from F<newsstats.conf> |
2832c235 TH |
332 | which should be present in the same directory via Config::Auto. |
333 | ||
334 | See doc/INSTALL for an overview of possible configuration options. | |
335 | ||
edd250f2 | 336 | You can override some configuration options via the B<--groupsdb> option. |
2832c235 TH |
337 | |
338 | =head1 OPTIONS | |
339 | ||
340 | =over 3 | |
341 | ||
edd250f2 | 342 | =item B<-V>, B<--version> |
2832c235 | 343 | |
edd250f2 | 344 | Print out version and copyright information and exit. |
2832c235 | 345 | |
edd250f2 | 346 | =item B<-h>, B<--help> |
2832c235 TH |
347 | |
348 | Print this man page and exit. | |
349 | ||
edd250f2 | 350 | =item B<-m>, B<--month> I<YYYY-MM[:YYYY-MM]|all> |
2832c235 | 351 | |
edd250f2 TH |
352 | Set processing period to a single month in YYYY-MM format or to a time |
353 | period between two month in YYYY-MM:YYYY-MM format (two month, separated | |
354 | by a colon). By using the keyword I<all> instead, you can set no | |
355 | processing period to process the whole database. | |
2832c235 | 356 | |
edd250f2 | 357 | =item B<-n>, B<--newsgroups> I<newsgroup(s)> |
2832c235 TH |
358 | |
359 | Limit processing to a certain set of newsgroups. I<newsgroup(s)> can | |
360 | be a single newsgroup name (de.alt.test), a newsgroup hierarchy | |
361 | (de.alt.*) or a list of either of these, separated by colons, for | |
362 | example | |
363 | ||
364 | de.test:de.alt.test:de.newusers.* | |
365 | ||
edd250f2 | 366 | =item B<-s>, B<--sums|--nosums> (sum per hierarchy level) |
2832c235 | 367 | |
edd250f2 TH |
368 | Include "virtual" groups for every hierarchy level in output, for |
369 | example: | |
2832c235 | 370 | |
edd250f2 TH |
371 | de.alt.ALL 10 |
372 | de.alt.test 5 | |
373 | de.alt.admin 7 | |
2832c235 | 374 | |
edd250f2 | 375 | See the B<gatherstats> man page for details. |
2832c235 | 376 | |
edd250f2 | 377 | =item B<--checkgroups> I<filename> |
2832c235 | 378 | |
edd250f2 TH |
379 | Restrict output to those newgroups present in a file in checkgroups format |
380 | (one newgroup name per line; everything after the first whitespace on each | |
381 | line is ignored). All other newsgroups will be removed from output. | |
2832c235 | 382 | |
95d9fe2c TH |
383 | Contrary to B<gatherstats>, I<filename> is not a template, but refers to |
384 | a single file in checkgroups format. | |
385 | ||
edd250f2 | 386 | =item B<-r>, B<--report> I<default|average|sums> |
2832c235 | 387 | |
edd250f2 | 388 | Choose the report type: I<default>, I<average> or I<sums> |
2832c235 | 389 | |
edd250f2 TH |
390 | By default, B<groupstats> will report the number of postings for each |
391 | newsgroup in each month. But it can also report the average number of | |
392 | postings per group for all months or the total sum of postings per group | |
393 | for all months. | |
2832c235 | 394 | |

395 | For report types I<average> and I<sums>, the B<group-by> option has no |
396 | meaning and will be silently ignored (see below). | |
2832c235 | 397 | |
edd250f2 | 398 | =item B<-l>, B<--lower> I<lower boundary> |
2832c235 | 399 | |
edd250f2 | 400 | Set the lower boundary. See B<--boundary> below. |
2832c235 | 401 | |
edd250f2 | 402 | =item B<-l>, B<--upper> I<upper boundary> |
2832c235 | 403 | |
edd250f2 | 404 | Set the upper boundary. See B<--boundary> below. |
2832c235 | 405 | |
edd250f2 TH |
406 | =item B<-b>, B<--boundary> I<boundary type> |
407 | ||
408 | Set the boundary type to one of I<default>, I<level>, I<average> or | |
409 | I<sums>. | |
410 | ||
411 | By default, all newsgroups with more postings per month than the upper | |
412 | boundary and/or less postings per month than the lower boundary will be | |
413 | excluded from further processing. For the default report that means each | |
414 | month only newsgroups with a number of postings between the boundaries | |
415 | will be displayed. For the other report types, newsgroups with a number of | |
416 | postings exceeding the boundaries in all (!) months will not be | |
417 | considered. | |
418 | ||
419 | For example, lets take a list of newsgroups like this: | |
420 | ||
421 | ----- 2012-01: | |
422 | de.comp.datenbanken.misc 6 | |
423 | de.comp.datenbanken.ms-access 84 | |
424 | de.comp.datenbanken.mysql 88 | |
425 | ----- 2012-02: | |
426 | de.comp.datenbanken.misc 8 | |
427 | de.comp.datenbanken.ms-access 126 | |
428 | de.comp.datenbanken.mysql 21 | |
429 | ----- 2012-03: | |
430 | de.comp.datenbanken.misc 24 | |
431 | de.comp.datenbanken.ms-access 83 | |
432 | de.comp.datenbanken.mysql 36 | |
433 | ||
434 | With C<groupstats --month 2012-01:2012-03 --lower 25 --report sums>, | |
435 | you'll get the following result: | |
2832c235 | 436 | |
edd250f2 TH |
437 | ----- All months: |
438 | de.comp.datenbanken.ms-access 293 | |
439 | de.comp.datenbanken.mysql 124 | |
2832c235 | 440 | |
edd250f2 TH |
441 | de.comp.datenbanken.misc has not been considered even though it has 38 |
442 | postings in total, because it has less than 25 postings in every single | |
95d9fe2c TH |
443 | month. If you want to list all newsgroups with more than 25 postings |
444 | I<in total>, you'll have to set the boundary type to I<sum>, see below. | |
628a183c | 445 | |
edd250f2 TH |
446 | A boundary type of I<level> will show only those newsgroups - at all - |
447 | that satisfy the boundaries in each and every single month. With the above | |
448 | list of newsgroups and | |
449 | C<groupstats --month 2012-01:2012-03 --lower 25 --boundary level --report sums>, | |
450 | you'll get this result: | |
2832c235 | 451 | |
edd250f2 TH |
452 | ----- All months: |
453 | de.comp.datenbanken.ms-access 293 | |
2832c235 | 454 | |
edd250f2 | 455 | de.comp.datenbanken.mysql has not been considered because it had less than |
95d9fe2c | 456 | 25 postings in 2012-02 (only). |
2832c235 | 457 | |
edd250f2 | 458 | You can use that to get a list of newsgroups that have more (or less) then |
95d9fe2c | 459 | x postings in every month during the whole reporting period. |
2832c235 | 460 | |
edd250f2 TH |
461 | A boundary type of I<average> will show only those newsgroups - at all -that |
462 | satisfy the boundaries on average. With the above list of newsgroups and | |
463 | C<groupstats --month 2012-01:2012-03 --lower 25 --boundary avg --report sums>, | |
464 | you'll get this result: | |
78389b28 | 465 | |
edd250f2 TH |
466 | ----- All months: |
467 | de.comp.datenbanken.ms-access 293 | |
468 | de.comp.datenbanken.mysql 145 | |
2832c235 | 469 | |
edd250f2 | 470 | The average number of postings in the three groups is: |
2832c235 | 471 | |
edd250f2 TH |
472 | de.comp.datenbanken.misc 12.67 |
473 | de.comp.datenbanken.ms-access 97.67 | |
474 | de.comp.datenbanken.mysql 48.33 | |
2832c235 | 475 | |
edd250f2 TH |
476 | Last but not least, a boundary type of I<sums> will show only those |
477 | newsgroups - at all - that satisfy the boundaries with the total sum of | |
478 | all postings during the reporting period. With the above list of | |
479 | newsgroups and | |
480 | C<groupstats --month 2012-01:2012-03 --lower 25 --boundary sum --report sums>, | |
481 | you'll finally get this result: | |
2832c235 | 482 | |
edd250f2 TH |
483 | ----- All months: |
484 | de.comp.datenbanken.misc 38 | |
485 | de.comp.datenbanken.ms-access 293 | |
486 | de.comp.datenbanken.mysql 145 | |
2832c235 | 487 | |
2832c235 | 488 | |
edd250f2 | 489 | =item B<-g>, B<--group-by> I<month[-desc]|newsgroups[-desc]> |
2832c235 | 490 | |
edd250f2 TH |
491 | By default, all results are grouped by month, sorted chronologically in |
492 | ascending order, like this: | |
78389b28 | 493 | |
edd250f2 TH |
494 | ----- 2012-01: |
495 | de.comp.datenbanken.ms-access 84 | |
496 | de.comp.datenbanken.mysql 88 | |
497 | ----- 2012-02: | |
498 | de.comp.datenbanken.ms-access 126 | |
499 | de.comp.datenbanken.mysql 21 | |
78389b28 | 500 | |
edd250f2 TH |
501 | The results can be grouped by newsgroups instead via |
502 | B<--group-by> I<newsgroup>: | |
503 | ||
504 | ----- de.comp.datenbanken.ms-access: | |
505 | 2012-01 84 | |
506 | 2012-02 126 | |
507 | ----- de.comp.datenbanken.mysql: | |
508 | 2012-01 88 | |
509 | 2012-02 21 | |
510 | ||
511 | By appending I<-desc> to the group-by option parameter, you can reverse | |
512 | the sort order - e.g. B<--group-by> I<month-desc> will give: | |
513 | ||
514 | ----- 2012-02: | |
515 | de.comp.datenbanken.ms-access 126 | |
516 | de.comp.datenbanken.mysql 21 | |
517 | ----- 2012-01: | |
518 | de.comp.datenbanken.ms-access 84 | |
519 | de.comp.datenbanken.mysql 88 | |
520 | ||
521 | Average and sums reports (see above) will always be grouped by months; | |
522 | this option will therefore be ignored. | |
523 | ||
524 | =item B<-o>, B<--order-by> I<default[-desc]|postings[-desc]> | |
525 | ||
526 | Within each group (a single month or single newsgroup, see above), the | |
527 | report will be sorted by newsgroup names in ascending alphabetical order | |
528 | by default. You can change the sort order to descending or sort by number | |
529 | of postings instead. | |
530 | ||
531 | =item B<-f>, B<--format> I<pretty|list|dump> | |
532 | ||
533 | Select the output format, I<pretty> being the default: | |
534 | ||
535 | ----- 2012-01: | |
536 | de.comp.datenbanken.ms-access 84 | |
537 | de.comp.datenbanken.mysql 88 | |
538 | ----- 2012-02: | |
539 | de.comp.datenbanken.ms-access 126 | |
540 | de.comp.datenbanken.mysql 21 | |
541 | ||
542 | I<list> format looks like this: | |
543 | ||
544 | 2012-01 de.comp.datenbanken.ms-access 84 | |
545 | 2012-01 de.comp.datenbanken.mysql 88 | |
546 | 2012-02 de.comp.datenbanken.ms-access 126 | |
547 | 2012-02 de.comp.datenbanken.mysql 21 | |
548 | ||
549 | And I<dump> format looks like this: | |
550 | ||
551 | # 2012-01: | |
552 | de.comp.datenbanken.ms-access 84 | |
553 | de.comp.datenbanken.mysql 88 | |

555 | de.comp.datenbanken.ms-access 126 | |
556 | de.comp.datenbanken.mysql 21 | |
557 | ||
558 | You can remove the comments by using B<--nocomments>, see below. | |
559 | ||
560 | =item B<-c>, B<--captions|--nocaptions> | |
561 | ||
562 | Add captions to output, like this: | |
563 | ||
564 | ----- Report for 2012-01 to 2012-02 (number of postings for each month) | |
565 | ----- Newsgroups: de.comp.datenbanken.* | |
566 | ----- Threshold: 10 => x <= 20 (on average) | |
567 | ----- Grouped by Newsgroups (ascending), sorted by number of postings descending | |
568 | ||
569 | False by default. | |
570 | ||
571 | =item B<--comments|--nocomments> | |
572 | ||
573 | Add comments (group headers) to I<dump> and I<pretty> output. True by default. | |
574 | ||
575 | Use I<--nocomments> to suppress anything except newsgroup names/months and | |
576 | numbers of postings. This is enforced when using B<--filetemplate>, see below. | |
577 | ||
578 | =item B<--filetemplate> I<filename template> | |
579 | ||
580 | Save output to file(s) instead of dumping it to STDOUT. B<groupstats> will | |
581 | create one file for each month (or each newsgroup, accordant to the | |
582 | setting of B<--group-by>, see above), with filenames composed by adding | |
583 | year and month (or newsgroup names) to the I<filename template>, for | |
584 | example with B<--filetemplate> I<stats>: | |
585 | ||
586 | stats-2012-01 | |
587 | stats-2012-02 | |
78389b28 TH |
588 | ... and so on |
