Output Fields

Table 1 lists the output fields for the show services sessions analysis command. Output fields are listed in the approximate order in which they appear.

Table 1: show services sessions analysis Output Fields
Field Name	Field Description
Services PIC Name	FPC and PIC slots for the services PIC on which the sessions are running.
Session Analysis Statistics:
Total Sessions Active	Total active sessions in the MS-PIC including TCP, UDP, ICMP and Softwires.
Total TCP Sessions Active	Total active TCP sessions in the MS-PIC.
Total UDP Sessions Active	Total active UDP session in the MS-PIC.
Total Other Sessions Active	Total other active sessions in the MS-PIC including ICMP and softwires.
Total Predicted Sessions Active	Predicted sessions are created only by the ALG traffic using the L3/L4 information available.
Created Sessions per Second	Session setup rate at the time of running the command.
Deleted Sessions per Second	Session deletion rate at the time of running the command.
Peak Total Sessions Active	Highest number of active sessions since the last PIC restart or since the last time session statistics are flushed.
Peak Total TCP Sessions Active	Highest number of active TCP sessions since the last PIC restart or since the last time session stats are flushed.
Peak Total UDP Sessions Active	Highest number of active UDP sessions since the last PIC restart or since the last time session statistics are flushed.
Peak Total Other Sessions Active	Highest number of other active sessions since the last PIC restart or since the last time session statistics are flushed.
Peak Created Sessions per Second	Maximum session setup rate observed since the last PIC restart or since the last time session statistics are flushed.
Peak Deleted Sessions per Second	Maximum session deletion rate observed since the last PIC restart or from the last time session statistics are flushed.
Packets received	Total number of packets received by the MS-PIC.
Packets transmitted	Total number of packets transmitted by the MS-PIC.
Slow path forward	Number of packets forwarded in the slow path (that is, after the successful rule match and session creation).
Slow path discard	Number of packets discarded before the session creation.
Session Rate Data: Number of Samples	Number of samples used to calculate the session rate since the last PIC restart or since the last time session statistics are flushed.
Session Rate Distribution(sec)
Session Operation :Creation	Number of sampling intervals during which a number of sessions in the indicated range were created during the current sampling period.
Session Operation :Deletion	Number of sampling intervals during which a number of sessions in the indicated range were deleted during the current sampling period.
Session Lifetime Distribution(sec):	Number of TCP, UDP, and HTTP sessions whose length was in the indicated range in seconds.
