SU: The Supervisor (p_ctmsu)
performs heartbeat monitoring of all processes
Before start of New Day, it suspends all the processes and then to itself

SL: The Selector (p_ctmsl)

Performs partial jobs post-processing actions
Frees all resources occupied by jobs

NS: The Network Server (p_ctmns)
Manage the communication to all Control-M/Agents
When a message arrives from the Agent, NS sends a trigger to a process that will handle the request
Updates the Agent status file and notifies TR, SL, CD and CS processes by sending triggers


TR: The Tracker (p_ctmtr)
Updates jobs state when informed by the agent
Performs late execution shouts and DO STMT
CO: Communication Gateway (p_ctmco)
It handles two types requests- one from CD like Download and other from Control-M/EM, to be handled by CS like order, view
It analyzes requests and sends them to the appropriate destination

CS: Communication Service (p_ctmcs)
All requests to the CS pass through the CO process
Handles the requests that comes from Control-M/EM
Multiple number of CS processes can be set

RT: Communication Router (p_ctmrt)
Manage the communication messages between all processes
Responsible for the messages to arrive in the correct order

WD: The Watchdog (p_ctmwd)
Monitors essential Control-M processes, resources and sends an appropriate alert when there is a problem
WD checks all the primary Control-M processes are functioning

LG: The Logger Process

CD: Communication Download Process (p_ctmcd)
CD process checks if the New Day Time has arrived
It sends a message to SU to suspend all Control-M processes and the “STOP LINK” message to Control-M/EM
CD updates the IOALOG about New-Day Beginning and updates a Date in the Control-M server database
It sends the New Day message to all available agents for cleanup purpose
It cleans the jobs from Active Job File, log messages and statistics information
It orders jobs upon their scheduling criteria to the AJF
Once New day is completed, it sends the “START LINK” message to Control-M/EM and a message to CO to activate all the Control-M processes

LG is actually "Agent utilities" (don't know where the LG came from.
It handles requests to run utilities from agent platforms (many Control-M/Server utilities can be initiated from the agent).
