When an OmniCenter license is installed, it is limited to a specific number of devices that can be managed (see Managed Devices for more information). A “device” is the basic unit of licensing and monitoring in OmniCenter. It is any single logical entity or operating system, such as a VM guest, VM host, single switch or stack of switches managed as a single entity.
OmniCenter’s licensing model is based on the number of devices being managed. Each device on your network managed by OmniCenter consumes one license. There are a few exceptions to this, however. Wireless access point devices and OmniCenter WebART checks are good examples. Wireless access points use the Netreo “Lite” license (see below), while OmniCenter’s WebART checks are not associated with any specific managed device, but take up a full license space by themselves due to their power and complexity.
The OmniCenter License Information page (Administrator → System → License) shows a detailed breakdown of your OmniCenter’s current licensing.
Lite Device License
Wireless access points are a good example of where you would use a Lite device license. Since wireless access points (WAP) are typically managed in groups through a single wireless controller (and only need to have their availability monitored and nothing else), Netreo introduced the “Lite” device license type to make managing these device types more cost-effective. Lite licenses are used for “ping only” devices, like WAPs, and help to greatly reduce the cost of monitoring your wireless environments.
If you are using wireless controllers in your environment, ask your Netreo representative for more information about this license type. Cisco Aironet devices are automatically recognized as Lite devices. All other devices that you want to be Lite require that the “Ping Only” device type be assigned to them.
What happens when my OmniCenter license expires?
14 days prior to license expiration date
A message will appear in the header of all OmniCenter web pages stating “License Expiring Soon.” This text will contain a link to a page containing this policy and the license expiration date. When viewing the policy, administrators will have the ability to “acknowledge” the expiration and therefore suppress the expiration emails that will be sent (defined below).
At expiration date
The morning of the day of expiration an email will be sent to all (email) contacts that have active alerts set for them (regardless of the time frame assigned to them) warning of the expiration and defining this policy—unless this step has been suppressed by an administrator during the period listed above.
1 day after expiration date
The morning after the expiration date (at 1 a.m. according to the local server clock) the web interface and automated reporting engine will be shut down. The server web page will indicate that the license has expired, and provide information on how to renew the license, along with a link to install the new license key when one is obtained.
Polling, service checking, and all data collection and alerting (including active response) will continue to operate as normal.
30 days after expiration date
Service checking, polling and alerting will all be shut down. At this point the server will be completely inoperable. It will however maintain its configuration and data history. So, if an updated license is ever installed, the previously collected data will still be available.
