Initiating and monitoring upgrade status
The Web Element Manager further simplifies the software upgrade process by providing tools for managing system
configuration files:
Back-up Tool: Enables the Web Element Manager to transfer a copy of the configuration file currently being
used by a managed system at user-defined intervals. Files are transferred to the host server in a specific
directory. The number of files to retain in the directory is also configurable. This tool provides a useful
mechanism for testing configurations and/or quickly restoring a last-known-good configuration in the event of
an error.
Compare Tool: Provides a powerful tool for comparing the configuration files of two managed systems. Once
the two files are specified, a dialog appears displaying the two documents side-by-side. Line numbers are
added for convenience. Text additions, modifications, and deletions are displayed in different colors for easy
recognition. This tool can be useful on its own to determine variations between multiple iterations of the same
configuration file, or, when used in conjunction with the Back-up tool, it can provide an audit trail of
configuration changes that occurred during system operation.
Accounting Management
Accounting management operations allow users to examine and perform post-process statistical analysis on systems
managed by the Web Element Manager application.
The type of statistics used for element management-based accounting are called bulk statistics. Bulk statistics are
grouped into categories called schemas and are polled by the system at fixed polling intervals and then transferred to the
Web Element Manager at a different transfer intervals (defined in minutes).
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 ASR 5000 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
