   9 =head1 DESCRIPTION
  10
  11 collectd is a daemon that collects various system statistics periodically and
  12 stores them into RRD-files. Which data is collected depends on compile-time
  13 settings. The following features may be available:

 125 Specify an alternative config file. This is the place to go when you wish to
 126 change B<collectd>'s behavior. The path may be relative to the current working
 127 directory.
 128
 129 =item B<-P> I<E<lt>pid-fileE<gt>>
 130
 131 Specify an alternative pid file. This overwrites any settings in the config
 132 file. This is thought for init-scripts that require the PID-file in a certain
 133 directory to work correctly. For everyday-usage use the B<PIDFile>
 134 config-option.
 135
 136 =item B<-f>

 138 Don't fork to the background. I<collectd> will also B<not> close standard file
 139 descriptors, detach from the session nor write a pid file. This is mainly
 140 thought for 'supervisioning' init replacements such as I<runit>.

 147
 148 =head1 MODES
 149
 150 collectd can operate in four different operating modes. The modes are described
 151 below.
 152
 153 The simplest mode is the so called B<local mode>. Data is collected locally and
 154 written in RRD files that reside in I<DataDir>. This is the default mode when
 155 collectd is linked against C<librrd>.
 156
 157 The modes B<client mode> and B<server mode> are used to send data over a
 158 network and receive it again.
 159
 160 In B<client mode> the daemon collects the data locally and sends its results
 161 to one or more network addresses. No RRD files are written locally in this
 162 case. If collectd is not linked against C<librrd> this is the default mode.
 163
 164 If started in B<server mode> the daemon will listen on one or more interfaces
 165 and write the data it receives to RRD files. No data is collected locally.
 166
 167 In the last mode, B<log mode>, data is collected locally and written in
 168 text files that reside in I<DataDir>.
 169
 170 Please refer to L<collectd.conf(5)> for the configuration options and default
 171 values.
 172
 173 =head1 SPECIAL PLUGINS
 174
 175 =head2 apache
 176
 177 This module connects to an Apache or lighttpd webserver and expects the output
 178 produced by B<mod_status.c>. If requires B<libcurl> to set up the HTTP
 179 connection and issue the request(s). The following is a sample config for the
 180 Apache webserver. Under Apache, the use of C<ExtendedStatus on> is mandatory.
 181
 182   ExtendedStatus on
 183   <IfModule mod_status.c>
 184     <Location /mod_status>
 185       SetHandler server-status
 186     </Location>
 187   </IfModule>
 188
 189 This plugin requires further configuration. Please read L<collectd.conf(5)>.
 190
 191 =head2 cpufreq
 192
 193 This module reads F</sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq> (for
 194 the first CPU installed) to get the current CPU frequency. If this file does
 195 not exist make sure B<cpufreqd> (L<http://cpufreqd.sourceforge.net/>) or a
 196 similar tool is installed and an "cpu governor" (that's kernel module) is
 197 loaded.
 198
 199 =head2 email
 200
 201 This plugin collects data indirectly by providing a UNIX socket that external
 202 programs can connect to. A simple line based protocol is used to communicate
 203 with the plugin:
 204
 205 E-Mail type (e.g. "ham", "spam", "virus", ...) and size (bytes):
 206
 207   e:<type>:<size>
 208
 209 If C<size> is less than or equal to zero, C<size> is ignored.
 210
 211 Spam score:
 212
 213   s:<value>
 214
 215 Successful spam checks (e.g. "BAYES_99", "SUBJECT_DRUG_GAP_C", ...):
 216
 217   c:<type1>[,<type2>,...]
 218
 219 Each line is limited to 256 characters (including the newline character).
 220 Longer lines will be ignored.
 221
 222 =head2 exec
 223
 224 The C<exec> plugin forks of an executable and reads back values that it writes
 225 to C<STDOUT>. The executable is forked kind of as L<init> does: It is forked
 226 once and not again until it exits. If it exited, it will be forked again after
 227 at most I<Interval> seconds. It is perfectly legal for the executable to run
 228 for a long time and continuously write values to C<STDOUT>.
 229
 230 The forked executable is expected to print values to C<STDOUT>. The expected
 231 format is as follows:
 232
 233 =over 4
 234
 235 =item
 236
 237 Each line beginning with a C<#> (hash mark) is ignored.
 238
 239 =item
 240
 241 Any other line must be of the form C<I<type>,I<type-instance>,I<value>>, where
 242 I<type> is either B<counter> or B<gauge>, I<type-instance> may not contain
 243 C<,> (comma), C</> (slash) and C<\0> (null byte) and I<value> is either an
 244 integer (if I<type> is B<counter>) or a floating-point number (if I<type> is
 245 B<gauge>).
 246
 247 =back
 248
 249 The values are always considered to be "fresh", i.E<nbsp>e. the time is set to
 250 "now".
 251
 252 When collectd exits it sends a B<SIGTERM> to all still running
 253 child-processes upon which they have to quit.
 254
 255 =head2 mysql
 256
 257 Requires B<mysqlclient> to be installed. It connects to the database when
 258 started and keeps the connection up as long as possible. When the connection is
 259 interrupted for whatever reason it will try to re-connect. The syslog will
 260 contain loud complaints in case anything goes wrong.
 261
 262 This plugin issues C<SHOW STATUS> and evaluates C<Bytes_{received,sent}>,
 263 C<Com_*> and C<Handler_*> which correspond to F<traffic-mysql.rrd>,
 264 F<mysql_commands-*.rrd> and F<mysql_handler-*.rrd>. Also, the values of
 265 C<Qcache_*> are put in F<mysql_qcache.rrd> and values of C<Threads_*> are put
 266 in F<mysql_threads.rrd>. Please refer to the B<MySQL reference manual>,
 267 I<5.2.4. Server Status Variables> for an explanation of these values.
 268
 269 =head2 sensors
 270
 271 The B<sensors> module uses lm_sensors to retrieve sensor-values. This means
 272 that all the needed modules have to be loaded and lm_sensors has to be
 273 configured (most likely by editing F</etc/sensors.conf>. Read
 274 L<sensors.conf(5)> for details.
 275
 276 The B<lm_sensors> homepage can be found at
 277 L<http://secure.netroedge.com/~lm78/>.
 278
 279 =head2 mbmon
 280
 281 The B<mbmon> module uses mbmon to retrieve temperature, voltage, etc.
 282
 283 collectd connects to B<localhost> (127.0.0.1), port B<411/tcp>.
 284 The B<Host> and B<Port> options can be used to change these
 285 default values. See L<collectd.conf(5)> for details. C<mbmon> has to be
 286 running to work correctly. If C<mbmon> is not running timeouts may appear
 287 which may interfere with other statistics..
 288
 289 C<mbmon> must be run with the -r option ("print TAG and Value format");
 290 Debian's /etc/init.d/mbmon script already does this, other people
 291 will need to ensure that this is the case.
 292
 293 =head2 hddtemp
 294
 295 To get values from B<hddtemp> collectd connects to B<localhost> (127.0.0.1),
 296 port B<7634/tcp>. The B<Host> and B<Port> options can be used to change these
 297 default values. See L<collectd.conf(5)> for details. C<hddtemp> has to be
 298 running to work correctly. If C<hddtemp> is not running timeouts may appear
 299 which may interfere with other statistics..
 300
 301 The B<hddtemp> homepage can be found at
 302 L<http://www.guzu.net/linux/hddtemp.php>.
 303
 304 =head2 vserver
 305
 306 B<VServer> support is only available for Linux. It cannot yet be found in a
 307 vanilla kernel, though. To make use of this plugin you need a kernel that has
 308 B<VServer> support built in, i.e. you need to apply the patches and compile
 309 your own kernel, which will then provide the /proc/virtual filesystem that is
 310 required by this plugin.
 311
 312 The B<VServer> homepage can be found at L<http://linux-vserver.org/>.
 313
 314 =head1 RRD FILES
 315
 316 The RRD files are created automatically. The size of the RRAs depend on the
 317 compile time settings of I<step> and I<width>. With the default values (I<step>
 318 = B<10>, I<width> = B<1200>) the following RRAs are created:
 319
 320   RRA:AVERAGE:0.1:1:8640
 321   RRA:AVERAGE:0.1:50:1210
 322   RRA:AVERAGE:0.1:223:1202
 323   RRA:AVERAGE:0.1:2635:1201
 324   RRA:MIN:0.1:1:8640
 325   RRA:MIN:0.1:50:1210
 326   RRA:MIN:0.1:223:1202
 327   RRA:MIN:0.1:2635:1201
 328   RRA:MAX:0.1:1:8640
 329   RRA:MAX:0.1:50:1210
 330   RRA:MAX:0.1:223:1202
 331   RRA:MAX:0.1:2635:1201
 332
 333 By default collectd uses a 10 second I<step>. Thus the RRAs contain the
 334 following timespans. If you've changed the I<step> at compile time you will
 335 have calculate resolution and timespan yourself.
 336
 337   PDP per CDP |  Resolution  | Data points | Timespan
 338   ------------+--------------+-------------+---------
 339             1 | 10.0 seconds !        8640 ! 1 day
 340            50 |  8.3 minutes |        1210 | 1 week
 341           223 | 37.2 minutes |        1202 | 1 month
 342          2635 |  7.3 hours   |        1201 | 1 year
