Python-script every time you want to read a value with the C<exec plugin> (see
L<collectd-exec(5)>) and provides a lot more functionality, too.
-The minimum required Python version is I<2.3>.
+The minimum required Python version is I<2.6>.
=head1 CONFIGURATION
=item *
-B<2.> collectd will block I<SIGINT>. Pressing I<Ctrl+C> will usually cause
+B<2.> Python will be handling I<SIGINT>. Pressing I<Ctrl+C> will usually cause
collectd to shut down. This would be problematic in an interactive session,
-therefore this signal will be blocked. You can still use it to interrupt
-syscalls like sleep and pause but it won't generate a I<KeyboardInterrupt>
-exception either.
+therefore Python will be handling it in interactive sessions. This allows you
+to use I<Ctrl+C> to interrupt Python code without killing collectd. This also
+means you can catch I<KeyboardInterrupt> exceptions which does not work during
+normal operation.
To quit collectd send I<EOF> (press I<Ctrl+D> at the beginning of a new line).
A very simple read function might look like:
+ import random
+
def read(data=None):
vl = collectd.Values(type='gauge')
vl.plugin='python.spam'
To register those functions with collectd:
- collectd.register_read(read);
- collectd.register_write(write);
+ collectd.register_read(read)
+ collectd.register_write(write)
See the section L<"CLASSES"> above for a complete documentation of the data
types used by the read, write and match functions.

-Please feel free to send in new plugins to collectd's mailing list at
-E<lt>collectdE<nbsp>atE<nbsp>collectd.orgE<gt> for review and, possibly,
-inclusion in the main distribution. In the latter case, we will take care of
-keeping the plugin up to date and adapting it to new versions of collectd.

+=head2 Plugin C<cpusleep>
+
+This plugin doesn't have any options. It reads CLOCK_BOOTTIME and
+CLOCK_MONOTONIC and reports the difference between these clocks. Since
+BOOTTIME clock increments while device is suspended and MONOTONIC
+clock does not, the derivative of the difference between these clocks
+gives the relative amount of time the device has spent in suspend
+state. The recorded value is in milliseconds of sleep per seconds of
+wall clock.

+The C<gps plugin> connects to gpsd on the host machine.
+The host, port, timeout and pause are configurable.
+
+This is useful if you run an NTP server using a GPS for source and you want to
+monitor it.
+
+Mind your GPS must send $--GSA for having the data reported!

+The following elements are collected:

+The GPS data stream is fetch by the plugin form the daemon.
+It waits for data to be available, if none arrives it times out
+and loop for another reading.
+Mind to put a low value gpsd expects value in the micro-seconds area
+(recommended is 500 us) since the waiting function is blocking.
+Value must be between 500 us and 5 sec., if outside that range the
+default value is applied.
+
+This only applies from gpsd release-2.95.
