* Output can be written or sent to various destinations by the following
plugins:
- amqp
Sends JSON-encoded data to an Advanced Message Queuing Protocol (AMQP)
server, such as RabbitMQ.
- 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

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_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.
Operation
---------
* 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.
collectd and chkrootkit
-----------------------
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.
Prerequisites
-------------
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.
* aerotools-ng (optional)
Used by the `aquaero' plugin. Currently, the `libaquaero5' library, which
is used by the `aerotools-ng' toolkit, is not compiled as a shared object
nor does it feature an installation routine. Therefore, you need to point
collectd's configure script at the source directory of the `aerotools-ng'
project.

Configuring / Compiling / Installing
------------------------------------
To configure, build and install collectd with the default settings, run
`./configure && make && make install'. For detailed, generic instructions
see 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
