An agent that can be used to list running processes on remote machines.
This agent provides the following actions, for details about each please run
mco plugin doc agent/process
- list - List Processes
sys-proctable RubyGem on all your agent nodes, this Gem uses native extensions and so will need compilers:
NOTE: To install this gem you need to have a c++ compiler on your system
mcollective_agent_process::gem_dependencies: "sys-proctable": "1.2.0"
Add the agent and client:
mcollective::plugin_classes: - mcollective_agent_process
On Archlinux machines the following Hiera data will install the dependencies using native packages and you do not need compilers:
mcollective_agent_process::manage_gem_dependencies: false mcollective_agent_process::package_dependencies: ruby-sys-proctable: present
The Process client application can be configured to list only a subset of possible process field values. This can be configured in your client configuration file. Available fields are PID, USER, VSZ, COMMAND, TTY, RSS and STATE. Unconfigured the output will default to PID, USER, VSZ and COMMAND.
mcollective_agent_process::config: fields: PID, COMMAND, TTY, STATE

The Process agent also supplies a data plugin which uses the sys-proctable Gem to check if there exists a process that matches a given pattern and can be used during discovery or any other place where the MCollective discovery language is used.
mco rpc rpcutil ping -S "process('ruby').exists=true"
