Android event log

[polomora]

I'm having prpoblems with random crashes on my Samsung Galaxy S2. It's been rooted and now runs Cyanogenmod. I was wondering if there is an Android equivalent to Linux's dmesg command to view the log files located under /var/log. I's like to be able to view the kernel messages just before the crash occurred using a terminal or ssh. Or an app that interfaces to the Android's dmesg equivalent would be ideal.

I tried using the Android System Information app, but this displays an empty log

Many thanks,
Paul

Hi Paul

If there is a simple dmesg equivalent I don't know of it, but you can get the same information (and a whole lot more) from a logcat viewer app. I use Logcat Extreme but there are lots of others to choose from.

Thanks John,

I tried Logcat Extreme, and it displays the log from the moment when my phone was restarted after the crash.

It seems that the log is not persisted when Android crashes and then rebooted.
Is there a way to save the log to non-volatile memory when a fatal exception occurs, or just before a crash occurs?

(Un)fortunately I've never had reason to use it to diagnose hard crashes so I can't help. Hopefully one of the hard-core users with lots of Android crash experience will chip in.
