Since the daemon doesn't need to startup every time it wants to update the
files it's very fast and easy on the system. Also, the statistics are very
fine grained since the files are updated every 10 seconds.
The C<snmp-probe-host.px> script can be used to automatically generate SNMP
configuration snippets for collectd's snmp plugin (see L<collectd-snmp(5)>).

There are many possible approaches to deal with this issue. The virt plugin supports
All the above combined make it possible for a client to block forever waiting for one QMP
request, if QEMU itself is blocked. The most likely cause of block is I/O, and this is especially
true considering how QEMU is used in a datacenter.

+
+The plugin's configuration consists of a I<Transport> that configures
+communications to the AMQP 1.0 messaging bus and one or more I<Instance>
+corresponding to metric or event publishers to the messaging system.
+
+The address in the I<Transport> block concatenated with the name given in the
+I<Instance> block starting tag will be used as the send-to address for
+communications over the messaging link.
+
+The following options are accepted within each I<Transport> block:
+
+=over 4
+
+=item B<Host> I<Host>
+
+Hostname or IP-address of the AMQP 1.0 intermediary. Defaults to the
+default behavior of the underlying communications library,
+I<libqpid-proton>, which is "localhost".
+
+=item B<Port> I<Port>
+
+Service name or port number on which the AMQP 1.0 intermediary accepts
+connections. This argument must be a string, even if the numeric form
+is used. Defaults to "5672".
+
+=item B<User> I<User>
+
+=item B<Password> I<Password>
+
+Credentials used to authenticate to the AMQP 1.0 intermediary. By
+default "guest"/"guest" is used.

+
+This option specifies the prefix for the send-to value in the message.
+By default, "collectd" will be used.
+
+=item B<RetryDelay> I<RetryDelay>
+
+When the AMQP1 connection is lost, defines the time in seconds to wait
+before attempting to reconnect. Defaults to 1, which implies attempt
+to reconnect at 1 second intervals.
+
+=back
+
+The following options are accepted within each I<Instance> block:
+
+=over 4
+
+=item B<Format> B<Command>|B<JSON>|B<Graphite>
+
+Selects the format in which messages are sent to the intermediary. If set to
+B<Command> (the default), values are sent as C<PUTVAL> commands which are
+identical to the syntax used by the I<Exec> and I<UnixSock plugins>. In this
+case, the C<Content-Type> header field will be set to C<text/collectd>.
+
+If set to B<JSON>, the values are encoded in the I<JavaScript Object Notation>,
+an easy and straight forward exchange format. The C<Content-Type> header field
+will be set to C<application/json>.
+
+If set to B<Graphite>, values are encoded in the I<Graphite> format, which is
+"<metric> <value> <timestamp>\n". The C<Content-Type> header field will be set to
+C<text/graphite>.
+
+A subscribing client I<should> use the C<Content-Type> header field to
+determine how to decode the values.
+
+=item B<PreSettle> B<true>|B<false>
+
+If set to B<false> (the default), the plugin will wait for a message
+acknowledgement from the messaging bus before sending the next
+message. This indicates transfer of ownership to the messaging
+system. If set to B<true>, the plugin will not wait for a message
+acknowledgement and the message may be dropped prior to transfer of
+ownership.
+
+=item B<Notify> B<true>|B<false>
+
+If set to B<false> (the default), the plugin will service the
+instance write call back as a value list. If set to B<true> the
+plugin will service the instance as a write notification callback
+for alert formatting.
+
+=item B<StoreRates> B<true>|B<false>
+
+Determines whether or not C<COUNTER>, C<DERIVE> and C<ABSOLUTE> data sources
+are converted to a I<rate> (i.e. a C<GAUGE> value). If set to B<false> (the
+default), no conversion is performed. Otherwise the conversion is performed

+
+Please note that currently this option is only used if the B<Format> option has
+been set to B<JSON>.
