Configuring DNS and NetBIOS Resolution

Iotellect Network Manager resolves names of hosts via DNS and NetBIOS services for more comfortable visualization of collected data.

DNS resolution settings are available in the global configuration of NetFlow plugin:

Property

Description

Enabled

Enables/disables DNS name resolution. Disabling host name resolution ensures maximum performance.

DNS Resolution

Specifies the connection method for name resolution requests:

  • On Demand. DNS names will only be resolved during flow data visualization. This speeds up flow collection and improves server performance during flow collection, but flow visualization will always take additional time required to process all DNS names of addresses that needs to be displayed.
  • Persistent. DNS names will be resolved right after flow acquisition and persistently stored in the server database. This ensures quick flow visualization but may degrade flow collection performance. This mode is suitable for smaller networks.

Number of IP Addresses to Resolve as a Batch

Specifies a number of IP addresses sent in a single batch reverse DNS request.

The Number of Threads to Keep in the Pool

Specifies the minimum number of DNS request processing threads.

The Maximum Number of Threads to Allow in the Pool

Specifies the maximum number of DNS request processing threads.

NetBIOS resolution settings are also available in the global configuration of NetFlow plugin:

Property

Description

Enable NetBIOS Resolution
