I've got a vSphere 4.1 ESXi test box here, and for some reason it went down at some point today. I turned it back on, but can't find out where it keeps its logs for the time when it became unavailable. Looking in /var/log every log seems to only start from the last time since it was power cycled, which is absolutely useless if I'm trying to find a log entry for the event which caused it to shut down.

Any ideas?

We went through this with VMware support a few weeks ago, and their solution was to use an external syslog server. That obviously won't help you with this instance, but going forward you'll have all the logs.

Thanks. It's slightly ridiculous, but I'll just have to set up a syslog server just for this tiny environment. – growse Apr 24 '11 at 7:08
Sorta ridiculous, yes, but it's generally a best practice to have a central syslog server, anyway... – EEAA Apr 24 '11 at 15:19
are you saing that ESXi purges all the previous logs after reboot? – Vick Vega Apr 25 '11 at 16:05
My understanding is that ESXi doesn't keep any logs on disk at all. – EEAA Apr 25 '11 at 16:06
