command,
to monitor service status and performance and to troubleshoot operations.
The
show
commands used for monitoring and troubleshooting include keywords (parameters) that can fine-tune the
output to produce information on all aspects of the system, ranging from current software configuration through call
activity and status. The keywords, used in the procedures documented in this chapter, are intended to provide the most
useful and in-depth information for monitoring the system. To learn about all of the keywords possible, refer to the
Command Line Interface Reference. To learn about the details for the information in the
activity and status. The keywords, used in the procedures documented in this chapter, are intended to provide the most
useful and in-depth information for monitoring the system. To learn about all of the keywords possible, refer to the

In addition to the CLI documented in this chapter, the system supports other monitoring and troubleshooting tools:
SNMP (Simple Network Management Protocol) traps that indicate status and alarm conditions. Refer to the
SNMP MIB Reference for a detailed listing of these traps.
bulk statistics (performance data) which can be accessed in various manners. For a complete list of SGSN
supported statistics, refer to the Statistics and Counters Reference. For information about configuring the
formats for static collection, refer to the Command Line Interface Reference.
formats for static collection, refer to the Command Line Interface Reference.
threshold crossing alerts for conditions that are typically temporary, such as high CPU or port utilization, but can
indicate potentially severe conditions. For information on threshold crossing alert configuration, refer to the
Thresholding Configuration Guide.
