The system's support for CGW and MRME service 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.

The system can be configured to collect bulk statistics and send them to a collection server called a receiver. Bulk
statistics are collected in a group. The individual statistics are grouped by schema. The following is a partial list of
supported schemas:



SaMOG: Provides statistics to support the SaMOG Gateway.



System: Provides system-level statistics.



Card: Provides card-level statistics.



Port: Provides port-level statistics.

The system supports the configuration of up to four sets of receivers. Each set can have primary and secondary
receivers. Each set can be configured to collect specific sets of statistics from the various schemas. Bulk statistics can be
periodically transferred, based on the transfer interval, using ftp/tftp/sftp mechanisms.

Bulk statistics are stored on the receivers 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 headers and
footers only), 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.
