Re: How to use the IOS commands to monitor health of cisco netwo

Hello Swee,

as a starting point without knowing your specific needs you can be interested in:

sh ver | inc uptime

to know if the device is stable and has not reloaded recently

sh ver shows you also the reason for last reload and the name of the IOS image that is running.

cpu

sh proc cpu | inc util

to know if cpu is not too loaded

sh proc cpu history

memory

sh proc mem | inc Free

to see total and Free memory

these are the very basic parameters to check.

Multiple other checks are possible.

To be noted most of these commands have SNMP MIB counterparts that provide the same information and it is quite common for management systems to use SNMP to monitor state of multiple devices.

(these are UDP messages with no login access)

Hope to help

Giuseppe
