Counter: A counter records incremental data cumulatively and rolls over when the counter limit is reached.

|
Gauge: A gauge statistic indicates a single value; a snapshot representation of a single point in time within a defined time frame. The gauge changes to a new value with each snapshot though a value may repeat from one period to the next. The limit depends upon the data type.

Information: This type of statistic provides information, often intended to differentiate sets of statistics; for example, a VPN name or IP address. The type of information provided depends upon the data type.

|
Description: Total number of downlink packets that were queued but dropped due to T3-tunnel timer expiry during inter-SGSN RAU procedure.
Triggers: During inter-SGSN RAU at the old SGSN, neither Cancel Location or SGSN Context Ack are received when t3-tunnel timer is fired causing the RAU procedure to abort. If old RABs are not available, the data queued during the RAU will be dropped.
Availability: per SGTP service

|
Description: Total number of “invalid” packets received from GGSN or RNC with errors due to mismatch in payload length.
Triggers: Increments when received GTP-U (v1 and v0) header does not match with the actual payload length field.
