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 processors.
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 partial list of supported schemas:

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 IMG 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, IMG host name, IMG 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 graphing.
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.
