Event Detail Records (EDRs)

Event Detail Records (EDRs) are usage records with support to configure content information, format, and generation

triggers by the system administrative user.

EDRs are generated according to explicit action statements in rule commands. Several different EDR schema types,

each composed of a series of analyzer parameter names, are specified in EDR. EDRs are written at the time of each

event in CSV format. EDRs are stored in timestamped files that can be downloaded via SFTP from the configured

EDRs are generated on per flow basis, and as such they catch whatever bytes get transmitted over that flow including

retransmitted.

The EDRs can be generated in comma separated values (CSV) format as defined in the traffic analysis rules.

value is greater than 127 characters, in the EDR it is truncated to 127 characters.

Flow-overflow EDR

Flow-overflow EDR or Summary FDR is a feature to count the data bytes from the subscriber that are missed due to

various reasons in ECS.

In case any condition that affects the callline (FLOW end-condition like hagr, handoff) occurs, flow-overflow EDR

generation is enabled, an extra EDR is generated. Based on how many bytes/packets were transferred from/to the

subscriber for which ECS did not allocate data session. This byte/packet count is reflected in that extra EDR. This extra

EDR is nothing but ―flow-overflow‖ EDR or Summary FDR.

The extra EDR is generated if all of the following is true:

Subscriber affecting condition occurs (session-end, hand-off, hagr)

Flow-overflow EDR generation is enabled

EDR generation on session-end, hand-off or hagr is enabled

Number of bytes/packets for flow-overflow EDR is non-zero.

The bytes/packet count will be printed as a part of ―sn-volume-amt‖ attribute in the EDR. Hence, this attribute must be

configured in the EDR format.
