The Control Center Main, Editor, and Monitor screens require user access privileges. The Administrator screen and the N1 Provisioning Server command line interface require administrator access privileges. Figure 2–1 describes the different screens of the Control Center and the user roles required to access each screen.
The Main screen is used primarily by end users whose management privileges and responsibilities are limited to a specific account and the related farms. This screen displays after you log into the Control Center. This screen provides a summary view of farms within the end user's account. This screen is also the starting point for various management tasks for those farms. Figure 2–2 shows the various areas of the Main screen.
You use the Main screen to do the following tasks:
Read news and messages
View farm status and configuration within an account
The Main screen gives you access to various features:
News and Messages
Farm Details
Farm Chooser
Farm View Area
Only the latest known (stable) state of the farm is displayed in the Control Center Main screen.
The Farm Details and News Details window displays details of the Main screen feature with which you previously interacted. For example, if you clicked one of the items listed under the News Details previously, then the window displays the details for that item. If you clicked the Farm Chooser previously, then the window displays the farm details.
The News and Messages section provides links to useful information published by the administrators of the system. News and messages may be published globally or per account. When you click the link, the related article displays in the News Details section.
The Control Center administrator sets up the links in this window to provide users with a variety of information.
The Farm Details section displays the following information about the farm:
Name – The name of the farm in your account
State – The current state of the farm
Status – Monitoring feedback for the current farm displayed
I-Fabric – A set of managed infrastructure resources where the selected farm runs
Contract Type – Resource provisioning permissions for the farms and the type of contract (quota types) attached to the farm
Request History – The request history of the farm, that is, updates and changes to the farm
Resources – A graphical representation of the minimum and maximum limits and the current usage of various resources in the farm
When a new account is created and first used in the Control Center, the Farm Chooser is empty. However, after you start designing and activating farms, you use the Farm Chooser to do the following tasks:
View topologies that are Not Deployed and Deployed.
The Deployed view lists the farms that are Active or in Standby states
The Not Deployed view lists all other farms and includes those farms in Design and Inactive states
Check the state, status, and modification date of farms
The Farm Chooser lists the farms created by all users in the same account. Figure 2–3 shows an example of the Farm Chooser window.
Farms selected in the Farm Chooser are displayed in the farm view area. When a selected farm is in Design state, the farm buttons that display include Edit a farm, create a New farm, and Delete a farm in Design or Inactive state. When the farm is in Active state, the Monitor button replaces the Delete button.
The Farm View Area displays a farm previously selected from the Farm Chooser every time you log on to the Control Center.
You access most administrative functions associated with managing a farm from the Control Center Administration screen.
You must have administrator access privileges to use the Administration screen.
Use the Control Center Administration screen to do the following tasks:
Set up accounts – Organization or departmental information.
Set up user access controls – User roles, login name, password, and contact information.
Set up contract types – Create types of resource provisioning limits (quotas) for the farms associated with an account.
Set up news content – Provide users with information such as industry notices, system-wide network status, system-wide alerts, and system maintenance schedules.
Unblock farm requests to enable you to approve farm activations, deactivations, changes, and deletions.
Set up contract parameters to define the provisionable resource limits (quotas) for the farm.
List devices and I-Fabrics and associate them with each other.
This screen contains three main sections.
Tools bar on the left side of the screen provides direct access to all the main features of the Administration screens.
Navigation bar at the top of the screen provides access between User and Administration screens of the Control Center.
Content displays on the right of the tools bar and below the navigation bar. This area displays the contents of each screen selected from the tools bar.
The navigation bar is common to all major screens in the Control Center. Use the navigation bar to perform the following actions.
Toggle between the Main, Editor, Monitor, and Administration screens.
Toggle between farms and different screens of the Control Center.
Access the Support and Account sections.
Logout of the Control Center.
The left part of the navigation bar provides access between the Main, Editor, and Monitor screens:
Main – Create users and accounts and view farms in selected accounts.
Editor – Select a farm to view or edit from the drop-down list.
Monitor – Select an active farm to monitor from the drop-down list.
On the right side of the navigation bar are the following options:
Admin – Access to the Administration screen (only available when you are logged in with administrator access privileges)
Account – To manage your user accounts
Logout – To exit the Control Center
The active screen in the Control Center is indicated by the highlighted screen name on the navigation bar and the title displayed on the bottom right. For example, Admin is highlighted on the navigation bar and the title Administration is displayed at the bottom right corner of the navigation bar.
The tools bar of the Administration screen enables you to select the current account and farm, and various administration tools to perform administrative tasks. The tools bar includes the following features:
Current Selections area where you can select the current account and farm with which to work
Lock Current Farm option to toggle the current farm between a locked and unlocked status
Administration Tools area to perform various administrative tasks
System Buttons so you can synchronize devices and software images known to the control plane software with the Control Center software
In the upper left corner of the window, you can select the account and farm associated with the account with which to work.
Current Account is used as the default account for all administration tasks. The selected current account gives you the ability to access all farms in the account.
Current Farm is the default farm displayed when navigating to other sections of the Administration screen. For example, the farm selected in the Current Farm is the default when options under the Farm Management Tools is selected.
As an administrator, you can use the Lock Current Farm option to prevent others from modifying a farm as long as you have the farm locked. With this feature, you toggle the current farm between the locked and the unlocked state. When you lock (and unlock) the farm, you must enter and confirm a password that is specific to that lock. If you forget your farm lock password, you can reset the password by using the command-line interface.
This function is applied only to farms that are in the active state.
The Control Center is a multi-user application. Hence, any user can edit any farm, user, or account at any time if the user has permission to do so. If two users make a change to the same farm, user, or account at the same time, the changes that the first user saves are applied. The second user to save changes is given the opportunity to overwrite the change by the first user. Otherwise, the second user's changes are discarded.
The features of the Administration section are grouped into three categories, as shown in the Administration Tools area of the Control Center window in Figure 2–6.
Farm Management Tools, for managing server farms.
Account Tools, for managing accounts.
Configuration Tools, for configuring basic features of the application.
The Control Center window contains two system buttons, as described in the following list.
Synchronize System is used for synchronizing devices and software images that are known to the control plane with the Control Center application.
Click Synchronize System whenever you add devices to an I-Fabric or when you add or change global software images using the command-line interface. Also synchronize system after you add a new I-Fabric.
Check System Configuration is used for validating I-Fabric configurations during the N1 Provisioning Server software installation.
Also check the system configuration each time you change a configuration parameter, such as the connector or an IP address. A dialog box displays the validation information for the system configuration and any error messages. Depending on the error that occurred, make the appropriate corrections, then check the system configuration again to ensure that the correct adjustment was made.
The Editor is used by administrators and end users. You use the Editor to do the following tasks:
Design a new farm
Import a farm
Export a farm
Configure a farm
Activate a farm
Modify a farm
Copy a farm
Save a farm
Deactivate a farm
Standby a farm
Figure 2–7 shows an example of the Editor screen.
In the Editor screen, the farm view area is where you assemble, connect, and configure farm elements.
This section describes various components of the Editor and their usage:

Select View Configuration (Main) or Configure (Editor) to display the following configuration screen.
The Monitor screen is used by administrators and end users. Monitoring is the mechanism used to ensure that the elements that are associated with the farms are behaving as expected. Every element in the farm is monitored to ensure network connectivity and basic responsiveness of the device. In addition, servers contain a special monitoring agent that enables you to configure monitoring beyond that of basic network connectivity.
The monitor component gives you various options for setting up and controlling the monitoring of your farm element. Figure 2–14 shows an example of the Monitor window.
The monitoring component of the Control Center enables you to do the following tasks:
Configure server specific monitors
Configure visual and email-based alarms
View the time-based status of the monitors
Monitors and alarms can be edited in the Configure Monitor dialog box or the Configure Alarm dialog box. You can reach dialog boxes through the Monitor screen.
Only the latest known (stable) state of the farm is displayed in the Control Center Monitor screen.
The Monitor option buttons located at the left side of the Editor area enable you to perform various operations in the Monitor. The User Groups and Contact Methods buttons are displayed only if you have account manager or administrator privileges. The Monitor buttons include the following options:
Option |
Description |
---|---|
User Groups |
Enables you to group users for automatic notification of monitoring alarms. This button links to an option in the Accounts area and launches a separate window. |
Contact Methods |
Enables you to set up lists of groups and preferred methods of contact for monitoring alarm notification. This button links to an option in the Accounts area and launches in a separate window. |
Commit Changes |
Saves any monitor or alarm changes, causing them to be uploaded and deployed for monitoring. This action commits the changes made since the last commit and generates a farm update request. |
Clicking Commit Changes can cause a disruption in monitoring while the changes are applied, because the update can take a while to be applied. Do not click Commit Changes twice because this action sends another update. Entries made in the various monitor and alarm windows and dialog boxes are recorded as you make them, but they are not saved until you click the Commit Changes button on the Monitor screen.
