NetStacks-Crawler
NetStacks-Crawler (formerly Netdisco) is the neighbor-discovery and inventory source for building topology — list devices, read neighbors, and bulk-import the discovered graph.
Overview
NetStacks-Crawler is the discovery source NetStacks uses to learn what is connected to what. It supersedes the older Netdisco integration; if you have existing notes referring to “Netdisco,” this is its replacement.
Configure a NetStacks-Crawler source with its base URL and API key. It is contacted only after you configure it; see the security page.
What It Does
- Device list — inventory of discovered devices.
- Neighbor discovery — per-device neighbor relationships used to draw links.
- Device links — the connection graph that feeds the topology canvas.
Bulk Topology Import
Rather than adding nodes one by one, import the entire discovered graph into the NetStacks topology in one action. The same one-click bulk import is available for LibreNMS sources. Imported nodes and links can then be arranged, annotated, and connected on the canvas.
Q&A
- Q: I see “Netdisco” in old docs — is that this?
- A: Yes. NetStacks-Crawler is the current name for that discovery integration.
- Q: Can I combine Crawler with SNMP and LibreNMS?
- A: Yes. Discovery sources are complementary and can all feed the same topology.
