202 | gatherstats - process statistical data from a raw source | |
203 | ||
204 | =head1 SYNOPSIS | |
205 | ||
93c8eae2 | 206 | B<gatherstats> [B<-Vhdt>] [B<-m> I<YYYY-MM> | I<YYYY-MM:YYYY-MM>] [B<-s> I<stats] [B<-c> I<filename template>]] [B<--hierarchy> I<TLH>] [B<--rawdb> I<database table>] [B<-groupsdb> I<database table>] [B<--clientsdb> I<database table>] [B<--hostsdb> I<database table>] |
2832c235 TH |
207 | |
208 | =head1 REQUIREMENTS | |
209 | ||
880c3eb2 | 210 | See L<doc/README>. |
2832c235 TH |
211 | |
212 | =head1 DESCRIPTION | |
213 | ||
214 | This script will extract and process statistical information from a | |
215 | database table which is fed from F<feedlog.pl> for a given time period | |
313610f6 | 216 | and write its results to (an)other database table(s). Entries marked |
880c3eb2 TH |
217 | with I<'disregard'> in the database will be ignored; currently, you |
218 | have to set this flag yourself, using your database management tools. | |
219 | You can exclude erroneous entries that way (e.g. automatic reposts | |
220 | (think of cancels flood and resurrectors); spam; ...). | |
2832c235 TH |
221 | |
222 | The time period to act on defaults to last month; you can assign | |
880c3eb2 TH |
223 | another time period or a single month via the B<--month> option (see |
224 | below). | |
2832c235 TH |
225 | |
226 | By default B<gatherstats> will process all types of information; you | |
880c3eb2 TH |
227 | can change that using the B<--stats> option and assigning the type of |
228 | information to process. Currently that doesn't matter yet as only | |
229 | processing of the number of postings per group per month is | |
230 | implemented anyway. | |
2832c235 TH |
231 | |
232 | Possible information types include: | |
233 | ||
234 | =over 3 | |
235 | ||
236 | =item B<groups> (postings per group per month) | |
237 | ||
238 | B<gatherstats> will examine Newsgroups: headers. Crosspostings will be | |
239 | counted for each single group they appear in. Groups not in I<TLH> | |
240 | will be ignored. | |
241 | ||
242 | B<gatherstats> will also add up the number of postings for each | |
243 | hierarchy level, but only count each posting once. A posting to | |
244 | de.alt.test will be counted for de.alt.test, de.alt.ALL and de.ALL, | |
245 | respectively. A crossposting to de.alt.test and de.alt.admin, on the | |
246 | other hand, will be counted for de.alt.test and de.alt.admin each, but | |
247 | only once for de.alt.ALL and de.ALL. | |
248 | ||
880c3eb2 TH |
249 | Data is written to I<DBTableGrps> (see L<doc/INSTALL>); you can |
250 | override that default through the B<--groupsdb> option. | |
2832c235 TH |
251 | |
252 | =back | |
253 | ||
254 | =head2 Configuration | |
255 | ||
880c3eb2 | 256 | B<gatherstats> will read its configuration from F<newsstats.conf> |
2832c235 TH |
257 | which should be present in the same directory via Config::Auto. |
258 | ||
880c3eb2 | 259 | See L<doc/INSTALL> for an overview of possible configuration options. |
2832c235 | 260 | |
880c3eb2 TH |
261 | You can override configuration options via the B<--hierarchy>, |
262 | B<--rawdb>, B<--groupsdb>, B<--clientsdb> and B<--hostsdb> options, | |
263 | respectively. | |
2832c235 TH |
264 | |
265 | =head1 OPTIONS | |
266 | ||
267 | =over 3 | |
268 | ||
880c3eb2 | 269 | =item B<-V>, B<--version> |
2832c235 | 270 | |
880c3eb2 | 271 | Print out version and copyright information and exit. |
2832c235 | 272 | |
880c3eb2 | 273 | =item B<-h>, B<--help> |
2832c235 TH |
274 | |
275 | Print this man page and exit. | |
276 | ||
880c3eb2 | 277 | =item B<-d>, B<--debug> |
2832c235 TH |
278 | |
279 | Output debugging information to STDOUT while processing (number of | |
280 | postings per group). | |
281 | ||
880c3eb2 | 282 | =item B<-t>, B<--test> |
2832c235 | 283 | |
880c3eb2 TH |
284 | Do not write results to database. You should use B<--debug> in |
285 | conjunction with B<--test> ... everything else seems a bit pointless. | |
2832c235 | 286 | |
880c3eb2 | 287 | =item B<-m>, B<--month> I<YYYY-MM[:YYYY-MM]> |
2832c235 | 288 | |
880c3eb2 TH |
289 | Set processing period to a single month in YYYY-MM format or to a time |
290 | period between two month in YYYY-MM:YYYY-MM format (two month, separated | |
291 | by a colon). | |
2832c235 | 292 | |
2832c235 | 293 | |
880c3eb2 | 294 | =item B<-s>, B<--stats> I<type> |
2832c235 TH |
295 | |
296 | Set processing type to one of I<all> and I<groups>. Defaults to all | |
297 | (and is currently rather pointless as only I<groups> has been | |
298 | implemented). | |
299 | ||
93c8eae2 TH |
300 | =item B<-c>, B<--checkgroups> I<filename template> |
301 | ||
302 | Check each group against a list of valid newsgroups read from a file, | |
303 | one group on each line and ignoring everything after the first | |
304 | whitespace (so you can use a file in checkgroups format or (part of) | |
305 | your INN active file). | |
306 | ||
307 | The filename is taken from I<filename template>, amended by each B<-- | |
308 | month> B<gatherstats> is processing, so that | |
309 | ||
310 | gatherstats -m 2010-01:2010-12 -c checkgroups | |
ad609792 | 311 | |
93c8eae2 TH |
312 | will check against F<checkgroups-2010-01> for January 2010, against |
313 | F<checkgroups-2010-02> for February 2010 and so on. | |
ad609792 | 314 | |
93c8eae2 TH |
315 | Newsgroups not found in the checkgroups file will be dropped (and |
316 | logged to STDERR), and newsgroups found there but having no postings | |
ad609792 TH |
317 | will be added with a count of 0 (and logged to STDERR). |
318 | ||

2832c235 TH |
