If we plan to take a device out of service for maintenance or other scheduled down time, we can set up a maintenance window so that Zenoss Core does not alert us of a problem when our scheduled maintenance starts. Using a maintenance window also helps ensure that the availability reports show accurate numbers. We'll cover reports in Chapter 10, Reviewing Built-in Reports. We define maintenance windows via the Administration properties of devices, device classes, systems, groups, or locations.
Let's walk through a quick example using a device of your choice:
- While viewing the device, click on the Administration link on the device's overview page.
- From the Maintenance Windows table, select Add Maint Window.
- In the Add Maintenance Window dialog box, enter a descriptive name: Upgrade.
- Click OK to add the maintenance window.
- Next, click on the name of the maintenance window to display the properties. We need to define the window.
- The following screenshot shows the configurable options for a maintenance window.
The following table outlines the available maintenance window properties:
|
Property |
Description |
|---|---|
|
Enabled |
Select true to activate the Maintenance window. Default is False. |
|
Start |
Enter the start date and time. |
|
Duration |
Specify the duration in Days, Hours, and Minutes. |
|
Repeat |
Select the interval to repeat the maintenance window. Available intervals are: Never Daily Every weekday Weekly Monthly First Sunday of the month |
|
Start Production State |
Specify the production state to move the devices into, once the maintenance window starts. Default is Maintenance. |
|
Stop Production State |
Specify the production state for the device after the maintenance window ends. The default selection is Original. |
By setting the production state to Maintenance, Zenoss Core continues to monitor the device; however, it will not send any alerts.
