Monitoring router reloads due to crash

[jderrien]

Hi ,

I'm looking for a way to detect router reloads due to software crash. One way of doing it is to have a script that connect on to the routers, issue a "sh ver" and lookup the

"System returned to ROM by <reason>". <reason> being the action that triggered the reload.

I also found a "whyReload" object in the OLD-CISCO-SYS MIBs which is a string variable that contains the reason why the router was restarted. In all the routers I have this object is set to "reload". I'm wondering what are the orther values that this object can have , especially in case of crash.

Anyone with some experience with this MIB , or idea suggestions on how to track this type of event ?

Thanks

Other values for this obeject include power-on, reload. I believe that for crashes, it would show somwthing like whyReload=bus error at PC 0x60F416B8.... etc. But do note that this object is deprecated.

Thanks for the information. Do you mean that you do not recommend to monitor this object because the MIB is or will not be suported anymore ? Are you aware of equivalent object available on more recent/supported MIB ?

Table 48: Deprecated and Replacement MIBs:

Isnt any replacement for whyReload so, you can use it for now.
