Historical Data Records (HDR)

HDR refers to a management feature that collects statistics about SBC system operation and function, and then sends those records to a configured FTP/SFTP server [1]. This is roughly the same data available via SNMP, but collected and stored in CSV files on configured intervals, and then sent to the server on a configured period. These files can be used for capacity planning and analysis of trends or long term issues.

HDR data consists of a “Group” with associated “Group Statistics” that apply to each group. HDR data comes from two sources: SNMP MIBs and Oracle’s Command Line Interface (ACLI), i.e. the output of show commands.

For more information and details about Historical Data Recording please read the HDR Resource Guide applicable to the release on the SD.

Specific HDR groups of interest to collect are:

system - global system statistics
session-realm - session and rate statistics on a per realm basis
temperature - environmental temperature statistics
sip-sessions - SIP status statistics
sip-errors - error statistics for SIP, media, and SDP
sip-policy - SIP routing, session-agent groups and constraints statistics
sip-ACL-status - statistics on trusted and blocked ACLs

The following is an example of information collected in the sip-errors HDR for one collection interval.
