I have a Cisco ASA5505 which crashes unpredictably. I want to log from it to see what the problem is before the device becomes unavailable.
Is it possible to configure logging so that log messages are written automatically to flash memory in the device? I know that buffer logging can write to flash memory when the buffer becomes full, but I'd like to write log messages straight to flash memory so that I don't lose the messages immediately before the device crashes.
I have no crash reporting module on the device and it seems to go down before logging anything to syslog/SNMP as I've tried these already.
Alternatively is it possible to use a USB port on the device to attach a USB pen drive and have the ASA log to that?
