.SH "DESCRIPTION"

\fBgcloud compute instances simulate\-maintenance\-event\fR simulates a host
maintenance event on a Compute Engine VM. For more information, see
https://cloud.google.com/compute/docs/instances/simulating\-host\-maintenance.



.SH "EXAMPLES"

To simulate a maintenance event on an instance named \f5\fItest\-instance\fR\fR
located in zone \f5\fIus\-east1\-d\fR\fR, run:

.RS 2m
$ gcloud compute instances simulate\-maintenance\-event \e
    test\-instance \-\-zone=us\-east1\-d
.RE



.SH "POSITIONAL ARGUMENTS"

.RS 2m
.TP 2m
\fIINSTANCE_NAMES\fR [\fIINSTANCE_NAMES\fR ...]

Names of the instances to operate on. For details on valid instance names, refer
to the criteria documented under the field 'name' at:
https://cloud.google.com/compute/docs/reference/rest/v1/instances

.SH "FLAGS"

.RS 2m
.TP 2m
\fB\-\-async\fR

Return immediately, without waiting for the operation in progress to complete.

.TP 2m
\fB\-\-with\-extended\-notifications\fR=\fIWITH_EXTENDED_NOTIFICATIONS\fR

Send an extended notification before simulating a host maintenance event on a
Compute Engine VM.

.TP 2m
\fB\-\-zone\fR=\fIZONE\fR

Zone of the instances to operate on. If not specified, you might be prompted to
select a zone (interactive mode only). \f5gcloud\fR attempts to identify the
appropriate zone by searching for resources in your currently active project. If
the zone cannot be determined, \f5gcloud\fR prompts you for a selection with all
available Google Cloud Platform zones.

To avoid prompting when this flag is omitted, the user can set the
\f5\fIcompute/zone\fR\fR property:

.RS 2m
$ gcloud config set compute/zone ZONE
.RE

A list of zones can be fetched by running:

.RS 2m
$ gcloud compute zones list
.RE

To unset the property, run:

.RS 2m
$ gcloud config unset compute/zone
.RE

Alternatively, the zone can be stored in the environment variable
\f5\fICLOUDSDK_COMPUTE_ZONE\fR\fR.
