NAME¶
cf-monitord - monitoring daemon for CFEngine
SYNOPSIS¶
cf-monitord [
OPTION]... [
FILE]
DESCRIPTION¶
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.
OPTIONS¶
- --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
- 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
- --legacy-output, -l
- Use legacy output format
- --color, -C
- Enable colorized output. Possible values: 'always', 'auto', 'never'. If
option is used, the default value is 'auto'
CFENGINE¶
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 daemon.
The daemon
cf-execd is responsible for running
cf-agent
periodically.
Documentation for CFEngine is available at
http://cfengine.com/documentation/.
PROMISE THEORY¶
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.
