Generating Error Dump for ESX

[ANKYIT]

Hi Guys,

I have a ESX 3.5 , which got restarted three times last week , there nothing conclusive found in logs which can suggest the root cause , Is there any possible way to confirgure ESX host to generate any dump which will help to analyses for any furture failures.

Also how the dump can be analyse.

Thanks in Advance.

you can use the "vm-support" command from Console.

And you can combine this command with "esxtop" command to replay the data later

Login to Console:

cd /tmp

vm-support -S -i 10 -d 180

It creates esxtop snapshot for every 10 seconds interval for duration of 180 seconds. The resulting file is tarball and gzipped.

esxtop -R /vm-support* (For the Analysis data later)

Thanks for your reply.

But actually I am aware of this VM-support , however there is nothing in logs that can advise root cause of restart , I would like to know is there anything same as Windows OS of creating some kind of other error \ Memory Dumps.
