The system's support for bulk statistics allows operators to choose to
view not only statistics that are of importance to them, but also to configure
the format in which it is presented. This simplifies the post-processing of
statistical data since it can be formatted to be parsed by external, back-end
When used in conjunction with the Web Element Manager, the data can be
parsed, archived, and graphed.
The system can be configured to collect bulk statistics (performance
data) and send them to a collection server (called a receiver). Bulk statistics
are statistics that are collected in a group. The individual statistics are
grouped by schema. Following is a list of supported schemas for HSGW:
Card: Provides card-level statistics
Context: Provides context-level statistics
Diameter-acct: Provides Diameter Accounting statistics
Diameter-auth: Provides Diameter Authentication statistics
ECS: Provides Enhanced Charging Service statistics
HSGW: Provides HSGW statistics
IMSA: Provides IMS Authorization statistics
IP Pool: Provides IP pool statistics
MAG: Provides Mobile Access Gateway statistics
Port: Provides port-level statistics
PPP: Provides Point-to-Point Protocol statistics
RADIUS: Provides per-RADIUS server statistics
RP: Provides RP statistics
System: Provides system-level statistics
The system supports the configuration of up to 4 sets
(primary/secondary) of receivers. Each set can be configured with to collect
specific sets of statistics from the various schemas. Statistics can be pulled
manually from the system or sent at configured intervals. The bulk statistics
are stored on the receiver(s) in files.
The format of the bulk statistic data files can be configured by the
user. Users can specify the format of the file name, file headers, and/or
footers to include information such as the date, system host name, system
uptime, the IP address of the system generating the statistics (available for
only for headers and footers), and/or the time that the file was generated.
When the Web Element Manager is used as the receiver, it is capable of
further processing the statistics data through XML parsing, archiving, and
The Bulk Statistics Server component of the Web Element Manager parses
collected statistics and stores the information in the PostgreSQL database. If
XML file generation and transfer is required, this element generates the XML
output and can send it to a Northbound NMS or an alternate bulk statistics
server for further processing.
Additionally, if archiving of the collected statistics is desired, the
Bulk Statistics server writes the files to an alternative directory on the
server. A specific directory can be configured by the administrative user or
the default directory can be used. Regardless, the directory can be on a local
file system or on an NFS-mounted file system on the Web Element Manager server.
