The service agent that lets you stop, start, restart and query the statuses of services on your operating system.
The service agent does not do any management of services itself. Instead it uses the functionality defined in MCollective::Util::Service classes to perform the actions. By default the Service agent ships with a PuppetService util class, but creating your own is as simple as adding a new class to util/service/ and implementing the start, stop, status and restart methods.
Follow the basic plugin install guide.
There is one plugin configuration setting for the service agent.
- provider - The Util class that implements the start, stop, restart and status behavior. Defaults to 'puppet'
General provider configuration options can then also be set in the config file.
plugin.service.provider = puppet
# Puppet provider specific options
plugin.service.puppet.hasstatus = true
plugin.service.puppet.hasrestart = true
% mco rpc service status service=httpd -W /dev_server/
Determining the amount of hosts matching filter for 2 seconds .... 4

stopped = 1
Finished processing 4 / 4 hosts in 241.49 ms
% mco service puppet stop

The Service agent also supplies a data plugin which uses the Service agent to check the current status of a service. The data plugin will return 'running' or 'stopped' and can be used during discovery or any other place where the MCollective discovery language is used.
mco rpc rpcutil ping -S "service('myservice').status=running"
The Service agent also supplies a validator plugin that will validate if a given string is a valid service name.
validate :service, :service_name
The default service agent achieves platform portability by using the Puppet provider system to support service managers on all platforms that Puppet supports.
If however you are not a Puppet user or simply want to implement some new method of service management you can do so by providing your own backend provider for this agent.
A service provider that uses the service system command has also been
contributed; it can be configured to work with any command that responds to
mycommand myservice start/stop/restart/status.
The logic for the Puppet version of this agent is implemented in Util::Service::PuppetService, you can create a custom service implementation that overrides #start, #stop, #restart, and #status.
To provide compatibility with the service data plugin #status should return 'stopped' if the service is stopped, and 'running' if the service is running.
This agent defaults to Util::Service::PuppetService but if you have your own you can configure it in the config file using:
plugin.service.provider = puppet
