What is a kernel.log? How can it be useful?

1 post in this topic

Recommended Posts

Sometimes while we are troubleshooting problems, we have to boot in verbose mode (famous -v at the boot prompt). Sometimes, however, the information passes so fast we can't observe it correctly! Everything recorded in verbose mode is recorded in kernel.log. It also keeps up-to-date errors and status updates while booted in the operating system, so it can assist in troubleshooting post-boot errors as well. Note, however, that this log does not show application crashes. You can view crash logs in the same application, but they are not contained in kernel.log.

 

First, we will open Console; this is located in /Applications/Utilities. Once inside, we need to click Show All Logs (Snow Leopard) or Show Log List:

Now click the disclosure triangle by /private/var/log (Snow Leopard) or /var/log (Lion):

And now we can click kernel.log:

Now, to look at logs starting from the last boot, look for "nvphash=4095"

Now you can take any errors and research their respective solutions.
