Monitoring Events A primary function of the NonStop NET/MASTER MS product is to process messages
that report the occurrences of events throughout the network.
Messages may be:
Solicited (responses to commands)
Unsolicited (generated by the occurrence of an event)
Examples of unsolicited messages you might receive are as follows:
Messages sent from other operators by using the MSG command, if your
PROFILE MSG=YES
Monitor-class messages (messages that have the monitor-class attribute set)
such as notification of other users logging on or off the system, if the Monitor
Status field in your user ID definition record is set to Y and your PROFILE
MONMSG=YES. (Your OCS prompt will have an M as the first character)
Tandem EMS and IBM PPO messages, if the Receive EMS Messages field in
your user ID definition record is set to Y and your PROFILE EMS=YES
Both solicited and unsolicited messages may be further classified as:
Informational, such as the response to a command
Critical, such as a report that a terminal has failed. Critical events or events
requiring immediate action are highlighted
Messages are displayed in the OCS message display area, the OCS recall buffer, and in
the activity log.
Note You can also request that messages be displayed in your Command Entry facility message display area
(see Section 5, “System Support Services”).
The OCS message display allows you to monitor significant events or problems as they
occur throughout the network. The OCS recall buffer allows you to view the most
recent events (about 100 messages). The activity log allows you to view events that
occurred earlier. In addition, the activity log contains messages which were delivered
to other users' terminals.
The types of messages displayed on your OCS screen depend on:
The following fields in your user ID definition record:
Receive EMS Messages
Monitor Status
Message Code
Message Procedure
Minimum Severity Class
