amqp1 Sends JSON-encoded data to an Advanced Message Queuing Protocol (AMQP) 1.0 server, such as Qpid Dispatch Router or Apache Artemis Broker.
csv Write to comma separated values (CSV) files. This needs lots of diskspace but is extremely portable and can be analysed with almost every program that can analyse anything. Even Microsoft's Excel.
grpc Send and receive values over the network using the gRPC framework.
lua It's possible to implement write plugins in Lua using the Lua plugin. See collectd-lua(5) for details.
mqtt Publishes and subscribes to MQTT topics.
network Send the data to a remote host to save the data somehow. This is useful for large setups where the data should be saved by a dedicated machine.
perl Of course the values are propagated to plugins written in Perl, too, so you can easily do weird stuff with the plugins we didn't dare think of ;) See collectd-perl(5).
python It's possible to implement write plugins in Python using the python plugin. See collectd-python(5) for details.
rrdcached
Output to round-robin-database (RRD) files using the RRDtool caching
daemon (RRDcacheD) - see rrdcached(1). That daemon provides a general
implementation of the caching done by the rrdtool plugin.
rrdtool Output to round-robin-database (RRD) files using librrd. See rrdtool(1). This is likely the most popular destination for such values. Since updates to RRD-files are somewhat expensive this plugin can cache updates to the files and write a bunch of updates at once, which lessens system load a lot.
snmp_agent Receives and handles queries from SNMP master agent and returns the data collected by read plugins. Handles requests only for OIDs specified in configuration file. To handle SNMP queries the plugin gets data from collectd and translates requested values from collectd's internal format to SNMP format.
unixsock One can query the values from the unixsock plugin whenever they're needed. Please read collectd-unixsock(5) for a description on how that's done.
write_graphite Sends data to Carbon, the storage layer of Graphite using TCP or UDP. It can be configured to avoid logging send errors (especially useful when using UDP).
write_http Sends the values collected by collectd to a web-server using HTTP POST requests. The transmitted data is either in a form understood by the Exec plugin or formatted in JSON.
write_kafka Sends data to Apache Kafka, a distributed queue.
write_log Writes data to the log
write_mongodb Sends data to MongoDB, a NoSQL database.
write_prometheus Publish values using an embedded HTTP server, in a format compatible with Prometheus' collectd_exporter.
write_redis Sends the values to a Redis key-value database server.
write_riemann Sends data to Riemann, a stream processing and monitoring system.
write_sensu Sends data to Sensu, a stream processing and monitoring system, via the Sensu client local TCP socket.
write_syslog Sends data in syslog format, using TCP, where the message contains the metric in human or JSON format.
write_tsdb Sends data OpenTSDB, a scalable no master, no shared state time series database.
Logging is, as everything in collectd, provided by plugins. The following plugins keep us informed about what's going on:
logfile Writes log messages to a file or STDOUT/STDERR.
perl Log messages are propagated to plugins written in Perl as well. See collectd-perl(5).
python It's possible to implement log plugins in Python using the python plugin. See collectd-python(5) for details.
syslog Logs to the standard UNIX logging mechanism, syslog.
log_logstash Writes log messages formatted as logstash JSON events.
Notifications can be handled by the following plugins:
notify_desktop Send a desktop notification to a notification daemon, as defined in the Desktop Notification Specification. To actually display the notifications, notification-daemon is required. See http://www.galago-project.org/specs/notification/.
notify_email Send an E-mail with the notification message to the configured recipients.
notify_nagios Submit notifications as passive check results to a local nagios instance.
exec Execute a program or script to handle the notification. See collectd-exec(5).
logfile Writes the notification message to a file or STDOUT/STDERR.
network Send the notification to a remote host to handle it somehow.
perl Notifications are propagated to plugins written in Perl as well. See collectd-perl(5).
python It's possible to implement notification plugins in Python using the python plugin. See collectd-python(5) for details.
Value processing can be controlled using the "filter chain" infrastructure and "matches" and "targets". The following plugins are available:
match_empty_counter Match counter values which are currently zero.
match_hashed Match values using a hash function of the hostname.
match_regex Match values by their identifier based on regular expressions.
match_timediff Match values with an invalid timestamp.
match_value Select values by their data sources' values.
target_notification Create and dispatch a notification.
target_replace Replace parts of an identifier using regular expressions.
target_scale Scale (multiply) values by an arbitrary value.
target_set Set (overwrite) entire parts of an identifier.
Miscellaneous plugins:
aggregation Selects multiple value lists based on patterns or regular expressions and creates new aggregated values lists from those.
threshold Checks values against configured thresholds and creates notifications if values are out of bounds. See collectd-threshold(5) for details.
uuid Sets the hostname to a unique identifier. This is meant for setups where each client may migrate to another physical host, possibly going through one or more name changes in the process.
Performance: Since collectd is running as a daemon it doesn't spend much time starting up again and again. With the exception of the exec plugin no processes are forked. Caching in output plugins, such as the rrdtool and network plugins, makes sure your resources are used efficiently. Also, since collectd is programmed multithreaded it benefits from hyper-threading and multicore processors and makes sure that the daemon isn't idle if only one plugin waits for an IO-operation to complete.
Once set up, hardly any maintenance is necessary. Setup is kept as easy as possible and the default values should be okay for most users.
collectd's configuration file can be found at sysconfdir/collectd.conf.
Run collectd -h for a list of built-in defaults. See collectd.conf(5)
for a list of options and a syntax description.
When the csv or rrdtool plugins are loaded they'll write the values to
files. The usual place for these files is beneath /var/lib/collectd.
When using some of the plugins, collectd needs to run as user root, since only root can do certain things, such as craft ICMP packages needed to ping other hosts. collectd should NOT be installed setuid root since it can be used to overwrite valuable files!
Sample scripts to generate graphs reside in contrib/ in the source
package or somewhere near /usr/share/doc/collectd in most distributions.
Please be aware that those script are meant as a starting point for your
own experiments. Some of them require the RRDs Perl module.
(librrds-perl on Debian) If you have written a more sophisticated
solution please share it with us.
The RRAs of the automatically created RRD files depend on the step
and heartbeat settings given. If change these settings you may need to
re-create the files, losing all data. Please be aware of that when changing
the values and read the rrdtool(1) manpage thoroughly.
If you are using the dns plugin, chkrootkit(1) will report collectd as a
packet sniffer (<iface>: PACKET SNIFFER(/usr/sbin/collectd[<pid>])). The
plugin captures all UDP packets on port 53 to analyze the DNS traffic. In
this case, collectd is a legitimate sniffer and the report should be
considered to be a false positive. However, you might want to check that
this really is collectd and not some other, illegitimate sniffer.
To compile collectd from source you will need:
Usual suspects: C compiler, linker, preprocessor, make, ...
collectd makes use of some common C99 features, e.g. compound literals and mixed declarations, and therefore requires a C99 compatible compiler.
On Debian and Ubuntu, the "build-essential" package should pull in everything that's necessary.
A POSIX-threads (pthread) implementation. Since gathering some statistics is slow (network connections, slow devices, etc) collectd is parallelized. The POSIX threads interface is being used and should be found in various implementations for hopefully all platforms.
When building from the Git repository, flex (tokenizer) and bison (parser generator) are required. Release tarballs include the generated files – you don't need these packages in that case.

https://github.com/algernon/riemann-c-client
To configure, build and install collectd with the default settings, run
./configure && make && make install. For a complete list of configure
options and their description, run ./configure --help.
By default, the configure script will check for all build dependencies and
disable all plugins whose requirements cannot be fulfilled (any other plugin
will be enabled). To enable a plugin, install missing dependencies (see
section Prerequisites above) and rerun configure. If you specify the
--enable-<plugin> configure option, the script will fail if the depen-
dencies for the specified plugin are not met. In that case you can force the
plugin to be built using the --enable-<plugin>=force configure option.
This will most likely fail though unless you're working in a very unusual
setup and you really know what you're doing. If you specify the
--disable-<plugin> configure option, the plugin will not be built. If you
specify the --enable-all-plugins or --disable-all-plugins configure
options, all plugins will be enabled or disabled respectively by default.
Explicitly enabling or disabling a plugin overwrites the default for the
specified plugin. These options are meant for package maintainers and should
not be used in everyday situations.
By default, collectd will be installed into /opt/collectd. You can adjust
this setting by specifying the --prefix configure option - see INSTALL for
details. If you pass DESTDIR=<path> to make install, <path> will be
prefixed to all installation directories. This might be useful when creating
packages for collectd.
Collectd ships with a build.sh script to generate the configure
script shipped with releases.
To generate the configure script, you'll need the following dependencies:
The build.sh script takes no arguments.
Collectd can be built on Windows using Cygwin, and the result is a binary that runs natively on Windows. That is, Cygwin is only needed for building, not running, collectd.
You will need to install the following Cygwin packages:
To build, just run the build.sh script in your Cygwin terminal. By default, it installs
to "C:/Program Files/collectd". You can change the location by setting the INSTALL_DIR
variable:
$ export INSTALL_DIR="C:/some/other/install/directory" $ ./build.sh
or:
$ INSTALL_DIR="C:/some/other/install/directory" ./build.sh
To compile correctly collectd needs to be able to initialize static variables to NAN (Not A Number). Some C libraries, especially the GNU libc, have a problem with that.
Luckily, with GCC it's possible to work around that problem: One can define
NAN as being (0.0 / 0.0) and isnan as f != f. However, to test this
"implementation" the configure script needs to compile and run a short
test program. Obviously running a test program when doing a cross-
compilation is, well, challenging.
If you run into this problem, you can use the --with-nan-emulation
configure option to force the use of this implementation. We can't promise
that the compiled binary actually behaves as it should, but since NANs
are likely never passed to the libm you have a good chance to be lucky.
Likewise, collectd needs to know the layout of doubles in memory, in order
to craft uniform network packets over different architectures. For this, it
needs to know how to convert doubles into the memory layout used by x86. The
configure script tries to figure this out by compiling and running a few
small test programs. This is of course not possible when cross-compiling.
You can use the --with-fp-layout option to tell the configure script which
conversion method to assume. Valid arguments are:
* `nothing` (12345678 -> 12345678)
* `endianflip` (12345678 -> 87654321)
* `intswap` (12345678 -> 56781234)
