Best Practices For Achieving Faster Solarwinds Network Topology Mapper Discovery
Recently, we’ve heard from Solarwinds Network Topology Mapper (NTM) users with large networks, that performance during the discovery process is a bit sluggish. How can we improve it? To answer that question, one must understand how the NTM discovery engine works and what goes on behind the scenes before displaying the network diagram.
NTM includes a sophisticated multi-level discovery engine, which uses a combination of protocols and goes through 3 distinct phases in order to discover every node on a network and to produce a highly accurate map.
- The Node Detection Phase: Uses a combination of ICMP, SNMP and WMI Protocols to detect devices.
- The Polling Phase: Uses a Poller to collect connection data using CDP, LLDP, Bridge table and also STP to detect the role of each node.
- The Calculation Phase: Uses complex algorithm to calculate connectivity between nodes.
