Hi, been playing a little with Get-Log which is a nice feature.
However, it seems that it only gives you the current logs, not for instance vmkernel.1,2,3 etc?
Am i missing something or is this on purpose?
Our ESX servers are "loud" in the vmkernel logs so the current log is cycled pretty fast.
Any thoughts on this?

Hi Jerry,
Specifying Key parameter you can browse all available VC or ESX hosts logs.
VMKerner log is an ESX host log so you should pass VMHost parameter especially if you're currently connected to VC.
$esx = Get-VMHost <myhost> Get-Log -Key "vmkernel", "vmksummary", "vmkwarning" -VMhost $esx
To query available logs on your server, try this code:
$esx = Get-VMHost <myhost> $esxView = Get-View $esx.Id $si = Get-View ServiceInstance-ServiceInstance $diagM = Get-View $si.Content.DiagnosticManager $diagM.QueryDescriptions($esxView.MoRef)
So if an older logs are available you should see keys like vmkernel:vmkernel-2.log.
BTW you can filter vmkernel keys only using
$diagM.QueryDescriptions($esxView.MoRef) | where {$_.key.startswith("vmkernel")}
Regards,
Yasen
Yasen, are you sure that the "old" logs appear with the QueryDescriptions method ?
When I do this I only get pointers to the current logs not the old ones.
The keys I get are "hostd", "messages", "vmkernel" ... not for example vmkernel:vmkernel-2.log like you indicated.
And when I retrieve the logs I only get the lines from the current log not the old ones.
$logdesc = $diagM.QueryDescriptions($esxView.MoRef) $log = $diagM.BrowseDiagnosticLog($esxView.MoRef, $logdesc[<log-index>].Key, $null, $null)

Hi, I might have been unclear, i have no problems getting the current logs, vmkernel,hostd etc.
What i'm looking for is a way to reach the older logs with the same command.
When i use Get-Logtype on the host it only seems to expose the current ones?
Get-Logtype :
hostd server log in 'plain' format
messages server log in 'plain' format
vmkernel server log in 'plain' format
vmksummary server log in 'plain' format
vmkwarning server log in 'plain' format
vpxa VirtualCenter agent log in 'plain' format
So, do they need to do a rewrite stuff to enable this or am i missing some parameters to access those older logs?

Exactly my point, I can't see the "old" logs like Yasen stated.
Since the SDK method only seems to return the "current" logs (and not the "old" ones) I'm afraid there is something missing at a lower level than the VI Toolkit.

Well it seems I was misled by vpxd log where you can browse older logs in the way I describe in my previous post.
PS D:\> Get-LogType
Key Summary
vpxd:vpxd-0.log VirtualCenter server log in 'plain' format
vpxd:vpxd-1.log VirtualCenter server log in 'plain' format
vpxd:vpxd-2.log VirtualCenter server log in 'plain' format
vpxd:vpxd-3.log VirtualCenter server log in 'plain' format
vpxd:vpxd-4.log VirtualCenter server log in 'plain' format
vpxd:vpxd-5.log VirtualCenter server log in 'plain' format
vpxd:vpxd-6.log VirtualCenter server log in 'plain' format
vpxd:vpxd-7.log VirtualCenter server log in 'plain' format
vpxd:vpxd-8.log VirtualCenter server log in 'plain' format
vpxd:vpxd-9.log VirtualCenter server log in 'plain' format
vpxd:vpxd-index VirtualCenter server log in 'plain' format
Apparently vmkernel logs do not support such fuctionality because if you browse VI Client logs for the host you get same result as Get-LogType cmdlet.
Sorry if i mislead you also.
