Queue/pipe <strong>for</strong> pending action requests <strong>for</strong> the<br />

action agent. The pending action requests are<br />

filled by the message agent and the control<br />

agent. The action agent polls the queue every 5<br />

seconds.<br />

Queue on <strong>UNIX</strong> systems between the <strong>HP</strong>OM<br />

monitor command opcmon(1), the <strong>HP</strong>OM<br />

monitor API opcmon(3), and the monitor<br />

agent. The monitor agent checks the queue after<br />

the termination of the triggered monitor scripts<br />

or programs every 15 seconds, if externally<br />

monitored objects are configured.<br />

Queue/pipe used by the message agent and the<br />

message stream interfaces to transfer control<br />

sequences <strong>for</strong> message handling through the<br />

MSI.<br />

Queue/pipe used by the message agent and the<br />

message stream interfaces to transfer messages<br />

from MSI programs to the message agent.<br />

File that holds any messages that cannot be<br />

passed to the management server (<strong>for</strong> example, if<br />

the network is down). The messages are read<br />

from this file after the management server is<br />

available.<br />

Queue/pipe <strong>for</strong> local buffering of messages to be<br />

sent to the message receiver when the<br />

management server is not accessible.<br />

Queue (only on <strong>UNIX</strong> systems) between the<br />

<strong>HP</strong>OM message command opcmsg(1) or the<br />

<strong>HP</strong>OM message API opcmsg(3) and the message<br />

interceptor.<br />
