Examples
The show watchdog memory-state location node-id command allows you to determine the memory
state of a specified node.
RP/0/RP0/CPU0:router# show watchdog memory-state location 0/rp0/cpu0
Memory information:
The show process memory [job-id] location node-id command allows you to determine the processes
with the highest dynamic memory usage. The output of the command is sorted by the Dynamic memory
usage.

Purpose
Displays the available physical memory and memory usage
information of a specific process.
Displays information about the text, data, and stack usage
for a specific process.
Takes the initial snapshot of heap memory usage for all
processes on the router and sends the report to a temporary
file named /tmp/memcmp_start.out.
Takes the second snapshot of heap memory usage for all
processes on the router and sends the report to a temporary
file named /tmp/memcmp_end.out. This snapshot is
compared with the initial snapshot when displaying the
heap memory usage comparison report.
Displays the heap memory comparison report, comparing
heap memory usage between the two snapshots of heap
memory usage.
If the problem has not been determined and is not resolved,
contact Cisco Technical Support. For Cisco Technical
Support contact information, see the
