The '-log' option defaults to "hostd" when connected directly to a host or
|
|
when connected to VirtualCenter and a '-host' option is given. Otherwise,
|
|
the '-log' option defaults to "vpxd:vpxd.log". The '-host' option is ignored
|
|
when connected directly to a host. See 'govc logs.ls' for other '-log' options.

|

Examples:
|
|
govc logs -n 1000 -f
|
|
govc logs -host esx1
|
|
govc logs -host esx1 -log vmkernel`
