CF-RUNAGENT(8) System Manager's Manual CF-RUNAGENT(8)

NAME

cf-runagent - activate cf-agent on a remote host

SYNOPSIS

cf-runagent [OPTION]... [FILE]

DESCRIPTION

cf-runagent connects to a list of running instances of cf-serverd. It allows foregoing the usual cf-execd schedule to activate cf-agent. Additionally, a user may send classes to be defined on the remote host. Two kinds of classes may be sent: classes to decide on which hosts cf-agent will be started, and classes that the user requests cf-agent should define on execution. The latter type is regulated by cf-serverd's role based access control.

OPTIONS

Print the help message
Parallelize connections (50 by default)
Enable debugging output
Output verbose information about the behaviour of cf-runagent
Specify how detailed logs should be. Possible values: 'error', 'warning', 'notice', 'info', 'verbose', 'debug'
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 sent to a remote agent
Define a list of comma separated classes to be used to select remote agents by constraint
Print basic information about changes made to the system, i.e. promises repaired
(deprecated)
(deprecated)
Hail the following comma-separated lists of hosts, overriding default list
Enable interactive mode for key trust
Connection timeout, seconds
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
Enable even more detailed debug logging for specific areas of the implementation. Use together with '-d'. Use --log-modules=help for a list of available modules
Bundles to execute on the remote agent

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.
