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 P-GW:
APN
: Provides Access Point Name statistics
Card
: Provides card-level statistics
Context
: Provides context service statistics
Diameter-acct
: Provides Diameter Accounting statistics
Diameter-auth
: Provides Diameter Authentication statistics
ECS
: Provides Enhanced Charging Service statistics
EGTPC
: Provides Evolved GPRS Tunneling Protocol - Control message statistics
FA
: Provides FA service statistics
GTPC
: Provides GPRS Tunneling Protocol - Control message statistics
GTPP
: Provides GPRS Tunneling Protocol - Prime message statistics
GTPU
: Provides GPRS Tunneling Protocol - User message statistics
HA
: Provides HA service statistics
IMSA
: Provides IMS Authorization service statistics
IP Pool
: Provides IP pool statistics
LMA
: Provides Local Mobility Anchor service statistics
P-GW
: Provides P-GW node-level service statistics
Port
: Provides port-level statistics
PPP
: Provides Point-to-Point Protocol statistics
RADIUS
: Provides per-RADIUS server 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 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.
