Method, apparatus and computer program product implementing multi-tenancy for network monitoring tools using virtualization technology

A computer program product comprising a non-transitory computer readable memory medium storing a computer program, the computer program configured to be executed by a computer processing apparatus, wherein when the computer program is executed by the computer processing apparatus the computer processing apparatus is configured to manage a plurality of networks using virtualization at least by:

• instantiating an instance of a single tenant network management tool in a separate virtual machine for each network of the plurality of networks;
• performing data storage virtualization of a data storage apparatus coupled to the computer processing apparatus, the data storage virtualization providing at least data storage into a database on the data storage apparatus for multiple tenants;
• performing network address virtualization of an available private address range for each of the plurality of networks, wherein multiple tenants may have conflicting private address ranges on their corresponding networks;
• directing user requests associated with a specific network to a selected virtual machine corresponding to that specific network;
• causing the instance of the single tenant network management tool corresponding to the selected virtual machine to operate on the user request;
• and directing database queries from the plurality of networks into the database by examining the database queries according to a set of rules and rewriting those database queries that need to be rewritten according to the set of rules so that each database query from each network of the plurality of networks has a unique identification referencing a network management system of the network and conflicts are avoided between data stored into the database from the plurality of networks.

A method comprising:

• managing, by a computer processing apparatus, a plurality of networks using virtualization by performing at least the following:
• instantiating, by the computer processing apparatus, an instance of a single tenant network management tool in a separate virtual machine for each network of the plurality of networks;
• performing, by the computer processing apparatus, data storage virtualization of a data storage apparatus coupled to the computer processing apparatus, the data storage virtualization providing at least data storage into a database on the data storage apparatus for multiple tenants, each tenant corresponding to one of the plurality of networks;
• performing network address virtualization of an available private address range for each of the plurality of networks, wherein multiple tenants may have conflicting private address ranges on their corresponding networks;
• directing user requests associated with a specific network to a selected virtual machine corresponding to that specific network;
• causing the instance of the single tenant network management tool corresponding to the selected virtual machine to operate on the user request;
• and
• directing database queries from the plurality of networks into the database by examining the database queries according to a set of rules and rewriting those database queries that need to be rewritten according to the set of rules so that each database query from each network of the plurality of networks has a unique identification referencing a network management system of the network and conflicts are avoided between data stored into the database from the plurality of networks.
