Controlling Messages Sent to Users
As a system manager, you can control, on an individual or group-wide basis, the kinds
of event messages that a user receives. In the case of event messages, you can control
the minimum severity level and classes of messages that a user can receive. Although
users have a limited ability to alter such settings, you can control the range of options
available to a given user or group of users. See Section 4, “Managing User Access and
Privileges,” for an explanation of how you control the kinds of messages that a user
can receive.
Two important NCL procedures enable you to specify which messages a user receives.
The EMSPROC procedure filters and processes messages at a system-wide level
The MSGPROC procedure filters and processes messages received by the OCS
window of a specific user or group of users
You write these procedures and store them in an NCL procedure library. Only one
EMSPROC procedure is active in a single NonStop NET/MASTER MS system. Each
user can have up to two active OCS windows. Each OCS window can have a different
MSGPROC procedure for filtering and processing messages destined for the OCS
window, or no MSGPROC procedure. You can change the active EMSPROC
procedure and MSGPROC procedures dynamically. See Section 8, “Managing Event
Messages,” for additional information about installing the EMSPROC procedure.
Refer to the NonStop NET/MASTER NCL Programmer’s Guide for a detailed discussion
of writing and using the EMSPROC and MSGPROC procedures.
Customizing Message Presentation
You can also customize the presentation of messages to users. Network Control
Language (NCL) procedures and NonStop NET/MASTER MS commands can
highlight or assign color codes to specific messages and specific classes of messages.
For example, you could decide that you want all messages from a given node to
appear in the same color. Alternatively, you can use an NCL procedure to associate
specific colors with specific severity levels. For example, critical events could appear
in a bright, high-contrast color, and informative events could appear in a lower-
contrast color.
See Section 9, “Supporting Remote Operations,” for an explanation of how you assign
colors to all messages from a remote node. For additional information on assigning
colors to event messages, refer to the NonStop NET/MASTER MS Operator’s Guide and
the NonStop NET/MASTER NCL Programmer’s Guide.
You can also use NCL procedures to modify the text of a message before it appears on
a user’s screen. The NCL WRITE verb enables you to change the contents of a message
before the message is forwarded to users and other NCL procedures.
Tandem distributes an application called Rule Management Services (RMS) with
NonStop NET/MASTER MS. Among other operations, RMS lets you define rules to
customize message presentation. Refer to the NonStop NET/MASTER RMS
Management and Operations Guide for more information.
