This page provides instructions how to find scheduled maintenance, set maintenance windows, reschedule planned maintenance, and more. For an overview of maintenance updates and maintenance windows, see Maintenance policy.
Set a preferred window for maintenance on an instance
Console
Go to the Memorystore for Redis page in the Google Cloud console.
Memorystore for RedisClick the instance ID of the instance you want to set a maintenance window for.
Click Edit.
Under the Maintenance section, select the desired day and time for the maintenance window. The time is set in your local time zone.
Click Save.
gcloud
Run the following command to set a maintenance window for a Redis instance:
gcloud redis instances update INSTANCE_ID --region=REGION --maintenance-window-day=DAY --maintenance-window-hour=HOUR
Where:
- INSTANCE_ID is the ID of the instance
- REGION is the region where your instance is located
- DAY is the day you want maintenance to occur. Acceptable values
are:
MONDAY
,TUESDAY
,WEDNESDAY
,THURSDAY
,FRIDAY
,SATURDAY
,SUNDAY
- HOUR is the hour of the day in UTC time for when the maintenance
window starts. Acceptable values are
0
-23
For reference information, see gcloud redis instances update
Opt in to maintenance notifications
To turn on maintenance notifications:
Go to the Communication page in the Google Cloud console:
Click the Product Notifications tab.
Select your project from the dropdown menu.
In the row for Memorystore, toggle the email button to ON.
A maintenance notification email uses the title, "Upcoming maintenance for your
Cloud Memorystore instance [your-instance-name]"
. Each email address that
needs to receive notifications must opt in separately.
Maintenance notifications are set at the project level rather than on instances. Email notifications are sent to the email address associated with your Google account. It is not possible to configure a custom email alias (for instance, a team email alias).
Find scheduled maintenance
If maintenance has been scheduled for your instance, you can view it using the following instructions:
Console
Go to the Memorystore for Redis page in the Google Cloud console.
Memorystore for RedisClick the instance ID of the instance that you want to view scheduled maintenance for.
Under the Maintenance section, you can view the date and time of any scheduled maintenance updates.
gcloud
gcloud redis instances describe INSTANCE-ID --region=REGION
where:
- INSTANCE_ID is the ID of the instance
- REGION is the region where your instance is located
The output for scheduled maintenance is as follows:
maintenancePolicy: createTime: 'TIME_STAMP' updateTime: 'TIME_STAMP' maintenanceWindow: - day: DAY duration: 60 minutes hour: HOUR maintenanceSchedule: endTime: 'TIME_STAMP' startTime: 'TIME_STAMP'
Where:
maintenancePolicy
shows information on the creation time of your preferred maintenance policy and the last time the policy was updated.createTime
is when the maintenance policy is first created.updateTime
is when the maintenance policy was last updated.DAY
indicates the day of the week maintenance occurs.HOUR
indicates the hour in UTC time that maintenance begins.startTime
indicates the specific start time for a maintenance update that is scheduled for your instance.endTime
indicates the specific ending time for a maintenance update that is scheduled for your instance.TIME_STAMP
uses the RFC 3339 format.
Reschedule planned maintenance
To reschedule maintenance, see the instructions below:
Console
Go to the Memorystore for Redis page in the Google Cloud console.
Memorystore for RedisClick the instance ID of the instance you want to reschedule maintenance for.
Under the Maintenance section, click RESCHEDULE.
- You can only reschedule maintenance if you have a scheduled update, for your instance.
Choose between Update now, Defer to next scheduled window, and Custom day and time. For more information, see the overview of rescheduling maintenance.
If you want to update your instance immediately, select Update now and click Update.
If you want to delay the scheduled maintenance by one week, select Defer to the next scheduled window and click Reschedule.
If you want to designate a specific time, select Custom day and time, choose the new time, and click Reschedule.
gcloud
gcloud redis instances reschedule-maintenance INSTANCE_ID --region=REGION --reschedule-type=RESCHEDULE_TYPE [--schedule-time=RESHEDULE_TIME]
where:
- INSTANCE_ID is the ID of the instance
- REGION is the region where your instance is located
RESCHEDULE_TYPE is the type of rescheduled update. Available values are:
IMMEDIATE
: Starts the maintenance update immediatelyNEXT_AVAILABLE_WINDOW
: Defers maintenance until the next maintenance window. The next window is one week from the window in which maintenance was originally scheduledSPECIFIC_TIME
: Allows you to designate a specific time for the update. The rescheduled time must be no more than seven days from time of the original maintenance window
RESHEDULE_TIME You can only specify this value if you set
--reschedule-type
toSPECIFIC TIME
. This value uses the ISO 1801 format. For example,2020-01-16T16:56:00.000Z
. The time is set in UTC time.
