Command to show history of issues on a router?

[fentressema3]

I've tried looking through the forum and in Google for the simple command to Show history for issues that occurred on a cisco router. Is there one single command that will show all history of issues? I know there are specific commands for CRC errors, but is there just a general command? 

Thanks!

Hello @fentressema3 ,

for events occurred since last reboot

you can use

show log

For very critical events that cause the router to crach the router attempts to write a crashinfo file on the flash

So for serious issues look for crashinfo files using

dir flash:

or dir   /all

the crashinfo files contain binary info that are core dumps from router memory you would need to download the Cisco Analyzer or to submit them to Cisco TAC ( you need a valid contract)

Hope to help
