The agent processes provide the functionality for fault, event, service and performance management. The agent processes are distinguished into two categories, core and subagent. The core processes are primarily responsible for controlling agent startup and shutdown, monitoring the status of the other agents, communication functions, distribution, and configuration changes.

The most common process the "accidentally dies" is coda. Depending on the status on communications broker you can start it with the following commands:

  1. If communication broker is not running you need to execute command on the node (or using ssh from from the other server):
    ovc -start coda
  2. If communication broker is running  you can do it on the HPOM server with the command:
    opcragt -start -id coda failednode.firma.com

The agent processes extend the functionality of the agent platform to perform tasks, such as reading a logfile, monitoring a threshold, and intercepting a message or an SNMP trap. During operation, the agent processes send or accept information and instructions from other local HPOM processes or from the management server.

One parent process is responsible for managing the other agents. It starts, stops, and provides status on all of the other agents as required. In order for a subagent to run the policy, templates for the subagent must be installed. Policy templates are referred to as policies on HTTPS-based nodes and are called templates on RPC-based nodes.

For example, in order for the message interceptor to run, install the message policy along with the opcmsg command. In order for the logfile encapsulator to run, install the logfile components (at least one logfile policy), and so on. Following are descriptions of the HTTPS agent processes:
