Reference: What Discovery Collects
The attributes Native Discovery reads over SNMP, SSH and WMI.
The attributes each protocol reads from a device. How these values are written into configuration items is controlled by the Mapping Sets tab.
| Protocol | What the hub reads |
|---|---|
| SNMP (v1, v2c, v3) | System identity (description, object ID, name, location, uptime); interfaces with MAC addresses, speed, status and IP addresses; chassis serial and firmware from the physical entity table; memory and device description from host resources; vendor, device type, model and operating system derived from the device; neighbor links from LLDP and CDP. |
| SSH (Linux and macOS) | Hostname, operating system and kernel; manufacturer, model, serial, firmware and machine identity; network interfaces and, on Linux, LLDP neighbors; physical drives with health; CPU; memory and modules; chassis type and virtualization; filesystems; running services and listening ports; uptime and boot time; last login. |
| WMI (Windows) | Identity; hardware; storage; network; installed software; patches; services; processes; scheduled tasks; local accounts; and signals that relate a host to other devices. |
A class that a device cannot supply is left out rather than failing the whole device, which is normal on older systems.
