Shutdown Collection Scripts
Shutdown scripts are generated when a failure occurs and contains information on why the failure
occurred. The system attempts to gather as much information as possible upon failure.
RP/0/RP0/CPU0:router# dir harddisk:/shutdown
Directory of harddisk:/shutdown
3683 drwx 4096 Wed Dec 21 17:49:34 2005 node0_RP0_CPU0

39929724928 bytes total (39908044800 bytes free).
The shutdown scripts are saved as a zipped file (.gz). The following example shows how to view the
zipped files using Ksh commands.
RP/0/RP0/CPU0:router# run
# gzip -d node0_1_CPU0.log.first.gz
# cat node0_1_CPU0.log.first.gz
ASIC error Collection Scripts
ASICs are monitored for errors. There are preset thresholds for each ASIC which allows a specific
number of errors before an action is taken.
ASIC error scripts are generated when major thresholds are exceeded and the node is reloaded. The
scripts contain a snapshot of error types and number of errors for the ASIC on which they occurred.
RP/0/RP0/CPU0:router# dir harddisk:/ASIC-ERROR
Directory of harddisk:/ASIC-ERROR
1881 drwx 4096 Thu Jun 16 08:32:14 2005 node0_3_CPU0
2141 drwx 4096 Fri Oct 14 13:52:22 2005 node0_5_CPU0
See the “ASIC Errors” section on page 1-49 for information on ASIC errors.
Monitoring
Monitoring allows you to view interface, controller fabric, or controller SONET counters, and
auto-updating statistics on processes and threads in real-time. The following commands are used for
monitoring:
• monitor interface Command, page 1-67
• monitor controller Command, page 1-68
