For switches, try the commands sh post and sh environment alarm.
For routers, look at the logs for the first sign or sometimes you can use sh diag.
A word of caution: When using the sh environment alarm on a 2940/2950 switch, if you don't have RPS but you see some display that the RPS is bad or faulty, just ignore this. I don't remember the specific IOS version but this is a known minor bug.
There are many ways to check health and the performance of the network, you can create a quick list to according to the deferent device under CLI or use the management software, such as Cisco Works. LMS. I used to create a quick list and save it as desktop wallpaper.
