Hi Luiz, here you go:

DMP or DataMiner Probe is a stand-alone limited functionality unit, typically installed at remote sites, and serving as an interface between the local managed devices and the central DataMiner System.

DataMiner Probes enable operators to bring the power and intelligence of DataMiner to the most remote, isolated and/or unmanned locations, and to embed intelligent self-sustaining network management pockets within the operation. As a loosely coupled intermediate gateway, it guarantees the continuity you require for fault management, performance management and procedure automation (e.g. redundancy switching, automatic configuration for scheduled services and bookings, etc.).

DMPs are typically installed for example in remote VSAT terminals, satellite hubs, terrestrial transmitter sites, small network nodes, cellular network base centers, etc.

Whether or not to install a DMP on-site depends on a number of requirements – because rather than managing the devices via a locally installed DMP, it is of course possible to directly interact with the devices from the central DataMiner System – such as:

1. Connectivity: is there permanent connectivity to the remote sites? And, what is the available capacity?
   1. Permanent connections with sufficient bandwidth allow you to manage the devices on the remote site easily with a central DataMiner System. If the connection is not permanent and/or limited in bandwidth, it can be better to install a DMP, which manages the devices locally at the remote site, and transfers alarm information to the central DataMiner System (incident based communications)
2. Application: what is the application of DataMiner? Is it just used for monitoring or is it also, for example, responsible to automatically switch redundancy on devices at the remote site?
   1. If the latter is the case, it is recommended to have the onsite DMP – otherwise, when using a central DataMiner System to manage the devices directly, there would be no mission critical redundancy switching whenever the connectivity is lost between the central DataMiner System and the remote sites.

Note there are limitations associated with a DMP license, compared to a traditional DMA license:

• DMPs are not integrated into a DMS as a DMA, but instead function as a standalone gateway/proxy in between devices and a DMS.  This mainly to implement robust and continuous network management solutions in architectures including bandwidth deprived communication links or links with intermittent availability.
• DMPs are available with a capacity of 5, 10, 25 or maximum 50 devices.
• DMPs can cater for an unlimited number of user accounts, but only one user can remotely access the DMP via its web interface at any given time.
• DMPs don't provide a hierarchical view arrangement, and hence all devices are displayed in one single view, and one single graphical Visual Overview presentation (which can have multiple tab pages, arranging different devices or providing different perspectives on the systems managed by the DMP).
• DMPs have a historical storage capability for fault and performance data of up to maximum 7 days.  Historical information from DMPs is typically forwarded towards a DataMiner network management platform where it remains available for longer time spans.

A DataMiner Probe is typically deployed on a small but capable mini PC, such as the Intel Next Unit of Computing (NUC).
