Hello everyone,
Is there a way to log SNMP information to the local router and download it or access it at a later date? Looking to capture bandwith and CPU utilization as well as any error messages, etc but won't have an SNMP server set up for about a week.
Thanks in advance! All replies rated

There is no way to log the SNMP information and see it later about the counters as this is real time information.
Do you have a NAM module in your network?

Thanks. No NAM. What's the most I can do to capture information then? Just enable logging buffered?

Logging will capture you to a syslog the console messages. That wont have the counters you are looking for.
I was more thinking that you could run an rsh script from a server or linux end device and get periodically the show interface outputs for example. For that you need to enable rcmd on the router as per :
Or you could enable NBAR on the router and periodically over RSH get the show ip nbar protocol-discovery output that will have the 5 minutes counters per protocol.
Protocol counters also do come handy when you monitor traffic, it gives you a supplemental picture of what's happening.
Example of NBAR output:
Last clearing of "show ip nbar protocol-discovery" counters 4w5d
