HDR Data

HDR data consists of a “Group” with associated Group Statistics that apply to each group. HDR data comes from two sources:

  • Simple Network Management Protocol (SNMP) Management Information Bases (MIBs) (MIB-Associated Groups and Group Statistics)
  • Acme Packet’s Command Line Interface (ACLI) (ACLI-Associated Groups and Group Statistics)

When you configure HDR on the OCSBC, the Groups and associated Group Statistics are included in the collection of data. You can configure the OCSBC to collect all group statistics or specific group statistics. For information on configuring global collection, see Setting Global Collection. For information on specific group collections, see Setting Multiple Collection Groups.

When HDR is enabled, the OCSBC forwards statistical records to push servers which send the data (in standard format) to a receiving server for viewing in a comma-separated value (CSV) file. Before pushing a file, the collector creates the directory by group name for which the statistic belongs (for example, fan, sip-client, system, etc.), if the directory does not exist from a previous push.

The collector can push multiple CSV files per directory. Each file is formatted as <Unix timestamp>.csv (for example, 1302041977.csv). Within the file, each record also has an associated record timestamp. The filename timestamp is the time that the CSV file was create. The record timestamp is the window of time that the HDR collector used to collect the data. For more information on windows of time, see Windows of Time.

The first record of each file is a header containing the attribute name. For example, in the “System” directory, a file name of 13020441977.csv can contain the header attribute names of CPU Utilization, Memory Utilization, Health Score, Redundancy State, etc. The collector appends a Timestamp heading attribute to the beginning of every record as well.

Note:

The records in a CSV file may display differently, depending on the record data included in the file, and the method used to open the file. For more information about the display of record data in a CSV file, see Appendix A, CSV File Data Formats.

The following example shows the output from a “System” HDR collection. The output format reflects that the file was opened using the Unix command cat <timestamp>.csv.
