cf-monitord - monitoring daemon for CFEngine


cf-monitord [OPTION]... [FILE]


cf-monitord is the monitoring daemon for CFEngine. It samples probes defined in policy code and attempts to learn the normal system state based on current and past observations. Current estimates are made available as special variables (e.g. $(mon.av_cpu)) to cf- agent, which may use them to inform policy decisions.


--help, -h Print the help message --debug, -d Enable debugging output --verbose, -v Output verbose information about the behaviour of the agent --dry-run, -n All talk and no action mode - make no changes, only inform of promises not kept --version, -V Output the version of the software --no-lock, -K Ignore system lock --file, -f value Specify an alternative input file than the default --inform, -I Print basic information about changes made to the system, i.e. promises repaired --diagnostic, -x Activate internal diagnostics (developers only) --no-fork, -F Run process in foreground, not as a daemon --histograms, -H Ignored for backward compatibility --tcpdump, -T Interface with tcpdump if available to collect data about network --color, -C value Enable colorized output. Possible values: 'always', 'auto', 'never'. If option is used, the default value is 'auto' --timestamp, -l Log timestamps on each line of log output


CFEngine provides automated configuration management of large-scale computer systems. A system administrator describes the desired state of a system using CFEngine policy code. The program cf-agent reads policy code and attempts to bring the current system state to the desired state described. Policy code is downloaded by cf-agent from a cf-serverd dae‐ mon. The daemon cf-execd is responsible for running cf-agent periodically. Documentation for CFEngine is available at


CFEngine is built on principles from promise theory, proposed by Mark Burgess in 2004. Promise theory is a model of voluntary cooperation between individual, autonomous actors or agents who publish their intentions to one another in the form of promises. A promise is a declaration of intent whose purpose is to increase the recipient's certainty about a claim of past, present or future behaviour. For a promise to increase certainty, the recipient needs to trust the promiser, but trust can also be built on the verification that previous promises have been kept, thus trust plays a symbiotic relationship with promises. For an introduction to promise theory, please see
