A “device type” is a sort of blueprint that OmniCenter uses to identify the general type of a device (such as a Cisco router or a Windows server). When a new device is discovered, OmniCenter checks its “SysDescr” OID. If it can match specified strings in the OID with one of the OmniCenter configured device types, it automatically assigns that type to the new device. The device type configuration tells OmniCenter what method to use to communicate with that device, what statistics the device should be polled for, and what type of display personality should be used in its device dashboard. Additionally, each device type can have a device template specified for it that will be applied to any devices using that type at the “device type” level—performing a degree of automatic configuration. Once a device is assigned a type, OmniCenter has the basic information it needs to begin polling the device for performance data and performing status checks.
Device types can also be manually assigned to a device when it is added to OmniCenter through the manual add or import functions. It is also possible to change the device type of any currently managed device. A device may have only one device type assigned to it. If a device type you want to use is not available, you can easily create your own. Alternatively, additional device types can be downloaded from the Netreo cloud libraries.
Each device type can have a number of more specialized subtypes available to it.
A “device subtype” is a more specialized blueprint that is used to identify a more specific type of a device (such as an Exchange or SQL Windows server). Device subtypes tell OmniCenter what additional statistics a device should be polled for. Each device subtype can also have a device template specified for it that will be applied to any devices using that subtype at the “device subtype” level—performing a further degree of automatic configuration. Devices may have multiple subtypes assigned to them—and, by extension, multiple device templates—if their parent device types allow it.
Device subtypes can also be manually assigned to a device when it is added to OmniCenter. It is also possible to change the device subtype of any currently managed device. If a device subtype you want to use is not available, you can easily create your own. Alternatively, additional device subtypes can be downloaded from the Netreo cloud libraries.
While device types are generally assigned automatically, subtypes are not. However, subtypes can be automatically assigned through the use of the autoconfiguration rules.
Device types and subtypes are created and managed in Polling Administration.
