Checking logs
Ok, so its monday morning, I come in and there are an onslaught of emails (no change there) from some issues over the weekend.
It would seem there was ‘an issue with vmware’ and the virtual machines were restarting left right and center, imediately I think….Network issue.
To find the answer (for which I was correct) I used the following quick bit of code…
Connect-VIServer myviserver
$esx = Get-VMHost myhost
$log = Get-Log -Key “vmkernel” -VMhost $esx
$log.entries > c:\logs.txt
This showed that the service console nic had lost connection to the network, confirmed around 1hr later from our networks team saying the primary core had re-booted itself
