Introduction
The System tab is a read-only hardware and OS inventory for a device, pulled from the Level agent and updated on each check-in. It covers the operating system, system hardware, processors, motherboard, physical drives, memory modules, and network interfaces.
There's nothing to configure. It's read-only reference data.
System Details
Open any device from Devices (or any global view) and click the System tab in the left-side device navigation.
What's on This Tab
The page is divided into six sections: Operating system, System, Processors, Motherboard, Physical drives, Memory, and Network interfaces.
For sections that can have more than one entry — processors, drives, memory modules, and network interfaces — each item gets its own tab (CPU 1, CPU 2, Disk 1, Disk 2, and so on). Click the tab to switch between them.
A few things worth knowing:
Data freshness. Everything here reflects the last agent check-in. The agent syncs hardware inventory every 5 minutes, so data is typically no more than 5 minutes old on an online device.
Virtual machines. On VMs, the manufacturer, model, and serial number fields in the System section reflect the hypervisor platform (e.g., VMware, Inc. / VMware7,1) rather than the underlying physical host.
Blank fields. Some hardware doesn't expose certain identifiers to the OS. When the agent can't retrieve a value, the field shows "--". That's not an error — the data isn't available from the device.
Disk capacity. The Physical drives section shows raw disk size, not available free space. For per-partition free space, see the Disk widget on the Overview tab.
BIOS release date. Useful for spotting devices running outdated firmware, especially when a firmware CVE is in circulation.
Memory slots. The System section shows slots in use vs. total available. Cross-reference that with the number of DIMM tabs in the Memory section to see whether open slots exist for an upgrade.
Network interfaces. Physical adapters, virtual adapters, and loopback interfaces each appear as separate tabs. An interface with both IPv4 and IPv6 assignments shows both addresses in the IP address field.
FAQ
Where does this data come from? The Level agent collects hardware and OS inventory from the device and sends it on each check-in. Data accuracy depends on what the OS reports to the agent — virtual machines may return hypervisor-level identifiers for some fields (manufacturer, model, serial number) rather than physical hardware values.
How current is the information on this tab? The agent syncs hardware inventory every 5 minutes, so data is typically no more than 5 minutes old on an online device. If a device has been offline, the data reflects the last check-in before it went offline. The Last seen timestamp on the Overview tab tells you when that was.
Why are some fields showing "--" or blank? Some hardware doesn't expose certain identifiers to the OS (common on VMs, budget hardware, or some motherboards). When the agent can't retrieve a value, it leaves the field blank or shows "--". This isn't an agent error — it means the data isn't available from the device.
Who can see the System tab? Any technician with access to the device's group can view the System tab. Permissions are managed at the group level. See Workspace → Permissions for how access is configured.
