NAME

cf-execd - scheduling daemon for cf-agent

SYNOPSIS

cf-execd [OPTION]... [FILE]

DESCRIPTION

cf-execd is the scheduling daemon for cf-agent. It runs cf-agent locally according to a schedule specified in policy code (executor control body). After a cf-agent run is completed, cf-execd gathers output from cf-agent, and may be configured to email the output to a specified address. It may also be configured to splay (randomize) the execution schedule to prevent synchronized cf-agent runs across a network. Note: this daemon reloads it's config when the SIGHUP signal is received.

OPTIONS

Print the help message
Enable debugging output
Output verbose information about the behaviour of cf-execd
All talk and no action mode - make no changes, only inform of promises not kept
Output the version of the software
Specify an alternative input file than the default. This option is overridden by FILE if supplied as argument.
Define a list of comma separated classes to be defined at the start of execution
Define a list of comma separated classes to be undefined at the start of execution
Ignore locking constraints during execution (ifelapsed/expireafter) if "too soon" to run
Print basic information about changes made to the system, i.e. promises repaired
Activate internal diagnostics (developers only)
Specify how detailed logs should be. Possible values: 'error', 'warning', 'notice', 'info', 'verbose', 'debug'
Run as a foreground processes (do not fork)
Run once and then exit (implies no-fork)
Do not run as a service on windows - use this when running from a command shell (CFEngine Nova only)
Set the internal value of LD_LIBRARY_PATH for child processes
Enable colorized output. Possible values: 'always', 'auto', 'never'. If option is used, the default value is 'auto'
Log timestamps on each line of log output
Ignore def_preferred.json file in favor of def.json
Do not run database integrity checks and repairs at startup
Specify the directory for the socket for runagent requests or 'no' to disable the socket

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 https://docs.cfengine.com/.

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.
