CHAPTER 1: OVERVIEW
1.1 INTRODUCTION
Web ViewPoint is a powerful web-browser-based interface tool used to monitor performance and manage events
&operations of HP NonStop Servers. Web ViewPoint provides configuration options for a single point command
and control of a multi-node NonStop environment. Following are the major components of this on-line subsystem:
PERFORMANCE MONITORING:
Monitors major CPU, Disk, Process, TMF, and Netline entities. File entities are also monitored for the Integrity
servers. This information is displayed in a graphical format where a visual alert mechanism highlights areas that
require attention. A graphical operational drill-down interface is also provided. In most cases, clicking on a
displayed data field exposes other related information, as well as commands applicable to that component.
EVENT MONITORING & ANALYSIS:
NonStop subsystems and user applications report “Events” via NonStop’s Event Management System (EMS)
architecture. These Events are information which applications and subsystems generate and can be of different
severity (e.g. info only, warning, critical). Web ViewPoint offers a complete set of features to monitor these Events
on-line, review earlier ones, or do detail analysis on a selected set of Events. There are many options and criteria
which help the user select specifically the type of Events they would like to see or research. Moreover, the display
of the EMS messages is customizable whereby the user can choose which token(s) to view.
A subscription subsystem may further be used to proactively alert the user on any Event or Event type (fully
customizable). Users will be notified when these Events are generated, even when they are not actively monitoring
the online activity (e.g. they do not even have the Web ViewPoint monitor open). Alerts can be communicated in
any of the following forms (based on user’s preference per Event/type):
 Pop-up display
 Ebox
 Email
 Vocalization to a local speaker
 SMS text message to a cell phone
 SNMP trap directly to HP OpenView
OPERATION MANAGEMENT:
Interacting directly with the NonStop environment in order to carry out commands is a very important aspect to
the users; this can be achieved via two methods:
 Object Manager
This is a graphical basedinterface which can be used to interact with all NonStop subsystems as well as user
applications. A customizable script file identifies all subsystems/applications, their Objects, and Entities (e.g.
subsystem: storage to Object: disk to Entity: $data). The script file also defines the available commands and
syntax. Object Manager is then able to build a graphical view to all subsystems and make commands available
via simple clickable buttons. This can replace a TACL & Subsystem user interface where manual commands
need to be submitted and syntax followed.
 Central Command Manager
Central Command Manager (CCM) takes the Object Manager one step further, by implementing a “smart”
interface. This allows for a better integration of components, as well as a better user experience.
