Accounting statistics
Overview
Accounting statistics are available for network ports, SAPs, SDPs, and subscribers. Service accounting statistics typically provide service-usage data for billing requirements. Network accounting statistics provide service-quality data for SLA QoS compliance requirements. Subscriber accounting statistics provide subscriber profile usage information for billing and SLA compliance.
The information in an accounting statistics record includes the following:
Table 10-4: Accounting statistics record properties
Property |
Description |
---|---|
Accounting Policy ID |
The NFM-P accounting policy ID, which is optional; inclusion can be enabled from the NFM-P System Preferences form, and is disabled by default |
Final Count |
Contains a value greater than zero when a subscriber or SAP is deleted after the previous collection. The value represents the ordinal of the deleted object; for example, if the object is the first object deleted since the previous collection, the value is 1; the property has a value of 2 in the record of the second object deleted during the same collection interval, and so on. |
Forwarding Class |
Forwarding class associated with a queue |
Lag Port |
Identifies a LAG port |
Monitored Object |
Detailed information about the object for which the statistics are collected |
Monitored Object Name |
Name of the object for which the statistics are collected |
Periodic Time |
Not applicable to accounting statistics |
Port Id |
Identifies a port |
Queue Id |
Identifies a hardware queue |
Record Type |
Type of collection, for example, Scheduled Full |
Sap Id |
Physical port identifier portion of a SAP definition |
Sdp Id |
Identifies an SDP |
Site ID |
Identifies a site |
Site Name |
Identifies the name of a site |
SlaProfile Id |
Identifies the value assigned to an SLA profile |
Group ID |
Identifies the ISA-AA group |
Partition ID |
Identifies the partition ID within an ISA-AA group |
Subscriber Id |
Identifies a subscriber |
Subscriber Profile Id |
Identifies a subscriber profile |
Svc Id |
Identifies a service |
Time Captured |
Time when the NFM-P starts to process the data file collected from the NE |
Time Recorded |
Time when the statistics were collected on the NE |
All accounting statistics share certain common properties, with some additional properties for each statistic type.

Table 10-6: Accounting statistics counter definitions

Definition |
---|---|
All Octets Offered All Packets Offered |
Offered packets enter a queue and are dropped or forwarded. An octet value is a packet value expressed in Bytes. |
Forwarding Class |
The forwarding class of the traffic; this is a classification rather than a counter |
High Octets Dropped High Octets Offered High Pkts Dropped High Pkts Offered High Priority Octets Dropped High Priority Octets Offered High Priority Pkts Dropped High Priority Pkts Offered |
High-priority packets for a traffic class are marked as in-profile on the ingress classification or based on the forwarding class of the packet. High-priority forwarding classes include nc, h1, ef, and h2. See the appropriate node’s QoS guide for more information about forwarding class scheduler mapping. Offered packets enter a queue and are dropped or forwarded. Dropped packets are not forwarded through a queue. An octet value is a packet value expressed in Bytes. |
In Profile Octets Dropped In Profile Octets Forwarded In Profile Packets Forwarded In Profile Pkts Dropped In Profile Pkts Forwarded |
In-profile packets are received at a rate that is lower than the queue CIR. Forwarded packets are sent to an egress queue. Dropped packets are not forwarded through a queue. An octet value is a packet value expressed in Bytes. |
Long Duration Flows |
Subscriber host application sessions that are longer than 180s in duration |
Low Octets Dropped Low Octets Offered Low Pkts Dropped Low Pkts Offered Low Priority Octets Dropped Low Priority Octets Offered Low Priority Pkts Dropped Low Priority Pkts Offered |
Low-priority packets for a traffic class are marked as out-of-profile on the ingress classification or based on the forwarding class of the packet. Low-priority forwarding classes include l1, af, l2, and be. See the appropriate node’s QoS guide for more information about forwarding class scheduler mapping. Offered packets enter a queue and are dropped or forwarded. Dropped packets are not forwarded through a queue. An octet value is a packet value expressed in Bytes. |
Medium Duration Flows |
Subscriber host application sessions that are 180s or less in duration |
Net to Sub Active Flows Net to Sub Admit Flows Net to Sub Admit Octets Net to Sub Admit Pkts Net to Sub Deny Flows Net to Sub Deny Octets Net to Sub Deny Pkts |
Net to Sub traffic flows from the network to a subscriber. An active flow is a flow that is opened, closed, opened and closed, or continued during a collection interval. Admit objects are objects that are forwarded. Deny objects are objects that are not forwarded. An octet value is a flow or packet value expressed in Bytes. |
Num of Subs |
The number of subscribers that have the specified flow type |
Out Of Profile Octets Dropped Out Of Profile Octets Forwarded Out of Profile Packets Forwarded Out Of Profile Pkts Dropped Out Of Profile Pkts Forwarded |
Out-of -profile packets are received at a rate that is higher than the queue CIR. Forwarded packets are sent to an egress queue. Dropped packets are not forwarded through a queue. An octet value is a packet value expressed in Bytes. |
Short Duration Flows |
Subscriber host application sessions that are 30s or less in duration |
Sub to Net Active Flows Sub to Net Admit Flows Sub to Net Admit Octets Sub to Net Admit Pkts Sub to Net Deny Flows Sub to Net Deny Octets Sub to Net Deny Pkts |
Sub to Net traffic flows from a subscriber to the network. An active flow is a flow that is opened, closed, opened and closed, or continued during a collection interval. Admit objects are objects that are forwarded. Deny objects are objects that are not forwarded. An octet value is a flow or packet value expressed in Bytes. |
Total Flow Duration |
Aggregate duration, in seconds, of the completed flows at the time of collection. |
Total Flows Completed |
The number of completed flows in each direction |
Total Octets Dropped Total Octets Forwarded Total Packets Dropped Total Packets Forwarded |
Offered packets enter a queue and are dropped or forwarded. Forwarded packets are sent to an egress queue. Dropped packets are not forwarded through a queue. An octet value is a packet value expressed in Bytes. |
Total Term Flows |
The number of completed flows in each direction |
Uncoloured Octets Offered Uncoloured Packets Offered Uncoloured Pkts Forwarded Uncoloured Pkts Offered |
Octets and packets can be modified or colored using color profiles. Color profiling adds the ability to selectively treat packets received on a SAP as in-profile or out-of-profile regardless of the queue forwarding rate. This allows a customer or access device to color a packet out-of-profile with the intention of keeping the in-profile bandwidth for higher-priority packets. Offered packets enter a queue and are dropped or forwarded. Forwarded packets are sent to an egress queue. An octet value is a packet value expressed in Bytes. |
