Cisco Videoscape Distribution Suite Transparent

Caching CDR Guide

Release 5.6.1

August 2015

CDR Structure

Cisco VDS TC generates Cache Detail Records (CDRs) that detail the content that is handled by the system. These records include information on cache in, cache out, and forwarded content. In addition to this information, each HTTP related CDR includes information for its detected service group.

The following is a sample CDR record. A description of the parameters in this file are provided in the

CDR Parameters

section. For more examples, see the

CDR Examples

section.

Note The ASCII bell character, (hexadecimal value of x'07') differentiates a double quote, beginning or ending a string.

Filename

The CDR filename follows a predefined naming convention, that indicates the CDR version. Table 1-1 describes the parts of the filename using the filename pang_cdr.log.v43.ce-2.032315_234941.gz as an example.

Cisco Systems, Inc.

www.cisco.com

Cisco has more than 200 offices worldwide. Addresses, phone numbers, and fax numbers are listed on the

Cisco website at www.cisco.com/go/offices.

Description

This text indicates that this file is a CDR file.

Identifies the CDR version. In this example, version 4.3.

Note This determines the internal structure of the CDR file, which may vary between versions.

Cache engine from which the CDR file originated

(n indicates the cache engine number). In the example, this is a file from cache engine 2.

Date and time, indicated by two digits (month, date, year _ hour, minutes, seconds)

File Format

The format of the CDR file resembles that of the CSV:

All fields are ASCII characters.

Columns are separated by commas.

Nulls are represented by the character 0 (zero) placed between commas.

A bell character (

) is always printed within the CDR. This is hard coded and cannot be configured to something else.

The line delimiter is new line (\n).

CDR Parameters

The parameters of the CDR file provide details about the traffic that is handled and delivered by the

VDS TC system. Table 1-2 defines the parameters in a CDR record, using the following IPv6 CDR example. The ID # references are not part of the actual CDR record. They have been added to the example to identify the different parameters of the record:

HTTP Agent Hash

There are db files in Cisco VDS TC Release 5.6.1 that contain hash value-to-user agent mappings, such as C75E3DDB, Mozilla/5.0. To determine the user agent that generated the traffic for a CDR entry, you can look up the hash value in field # 46 of the CDR in this db file.

Each VDS TC cache engine generates its own hash db file, named http_agents.ce-#.db, where # is the cache engine number. The hash db files for all of the cache engines are automatically copied to the VDS

TC management server. Therefore, it is easiest to view these files from the VDS TC management server.

Note The size of these db files is limited to a maximum of 10,000 entries. The db files overwrite the least used agents with new entries once a day.

To see a list of available hash db files, from the VDS TC management server enter the command

/opt/pang/cdrs> ls *db*. After you have the name of a hash db file, to view its contents enter the command more filename. For example:

Note A termination code of TIMEOUT is normal for BitTorrent traffic. This is because the subscriber will open many TCP sessions to peers to receive different “chunks” of the file. After the file is finished downloading, some TCP connections may remain open until the TCP session times out because of no activity.
