Web Element Manager Overview
▀ Supported Features
▄ Cisco ASR 5000 Series Product Overview
OL-22938-02
Once the Web Element Manager server application, called the receiver, has received bulk statistics files from the
managed system, these files are parsed and added to the PostgreSQL database. This database is updated as new files are
received.
The Web Element Manager‘s accounting management functionality is compliant with TS 32.401, 3rd Generation
Partnership Project; Technical Specification Group Services and System Aspects; Telecommunication management;
Performance Management (PM); Concept and requirements
and allows you to:
Collect statistics pertaining to the transfer and collection of bulk statistics
Views statistics stored on the chassis prior to transfer to the receiver
Graph multiple received bulk statistics over time as either a line or bar graph; these graphs can be printed to
network printers accessible by the server
Generate eXtensible Markup Language (XML) files for transfer to a Northbound NMS or bulk statistics
processor
Archive collected bulk statistic information to conserve disk space on the server
Performance Management
Performance management operations supported by the Web Element Manager allow users to examine and perform real-
time statistical analysis on systems managed by the application as well as on the server on which the application is
running.
Information pertaining to various aspects of the Web Element Manager (CPU and memory utilization, disk space, and
process status) and its managed systems (hardware, protocols, software subsystems, and subscribers) is collected in real
time and is displayed in tabular format. Alternatively, most of the information can be graphed as a function of time in
either line or bar-chart format. Multiple statistics can be graphed simultaneously for quick comparison of data.
In addition to collecting and providing mechanisms for the real-time viewing of statistical information, the Web
Element Manager provides useful monitoring tools similar to those found in the CLI. These tools can be used to monitor
active subscriber sessions, protocol flows, and port information. Data collected during this monitor operation can be
saved to the client machine for further analysis.
Security Management
Security management pertains to the operations related to management users. This includes both Web Element Manager
application users and local management users who are configured on the chassis. In many cases, management users can
be allowed access to both the system (via its CLI) and the application. It is possible for both management user accounts
to share the same username and password.
The security management features of the Web Element Manager allow you to:
Add, modify, or delete administrative users for both the application and the managed system.
Regardless of the administrative user type, there are four levels of management user privileges:
Inspector : Inspectors are limited to a small number of read-only Exec Mode commands.The bulk of
these are ―show‖ commands giving the inspector the ability to view a variety of statistics and
