crash is an open source tool, you can have it on non rhel flavors as well. > I need to analyze when linux kernel crashes it generates a dmesg log ,i am > looking for document explains this dmesg crash log. > When your kernel crashes, those crash logs may not be available in the /var/log/messages (forget dmesg, it's a circular buffer that would be consumed even earlier). You need to configure something like kdump, netdump to have the kernel core dumped somewhere to be analysed later using tools such as crash.
