System configuration info
Home > Select Project > Labs > System configuration info
When you work with AI and HPC workloads, questions such as "which NUMA node is this GPU attached to?" or "which network interface is this RDMA port paired with?" come up. Performance metrics alone cannot answer them, and finding out requires connecting to each server and digging through sys paths. System configuration info is a Labs feature that queries the NUMA node and RDMA interface configuration of the Linux servers in a project, split into tabs on one screen. It is read-only and does not provide a feature to change values. It is intended for operators who also need to review device configuration.
How to access the Labs menu
System configuration info is included in the Labs menu and appears after OS Parameter info in the Labs menu. For how to access Labs features and the precautions, see the Labs document.
Supported agent versions
It is supported only on Linux agents 2.9.22 or later. Windows, AIX, HP-UX, and Solaris are not collected regardless of version. The collection option is on by default, so no separate configuration is needed.
Even with a supported version, it is normal for the table to be empty on a server that does not have the device. NUMA is collected on the assumption of the /sys/devices/system/node path and RDMA on /sys/class/infiniband, so no rows appear on the RDMA tab for a server without an RDMA driver.
Tab layout
| Tab | Description |
|---|---|
| NUMA configuration info | One row per NUMA node of the server. Shows the CPUs and memory in the node and the devices attached to it |
| RDMA configuration info | One row per RDMA interface of the server. Shows device and port identification and the connection status |
The current tab is included in the URL, so you can refresh or share a link with the tab selection preserved. Query conditions are kept when you move between tabs.
Selecting the query time
NUMA and RDMA configuration information is an inventory that is refreshed once a day. Unlike other system information screens, you therefore select a date and collection time rather than specifying a query range.
Fields on the NUMA configuration info tab
All ten columns are displayed by default.
| Field | Description |
|---|---|
hostname | Server name (host name) |
numaNodeId | NUMA node number |
cpuList | List of logical CPUs in the node (for example, 0-15,128-143) |
logicalCores | Number of logical cores in the node |
memorySize | Memory size allocated to the node |
gpuIndexes | List of GPU indexes attached to the node |
rdmaDevices | List of RDMA devices attached to the node |
rdmaNetDevs | List of operating system network interfaces corresponding to the RDMA devices above |
nvmeDevices | List of NVMe devices attached to the node |
gpuRdmaAffinity | Proximity between the GPU and the RDMA device (for example, GPU2:mlx5_2(PXB)) |
The default sort is ascending by server name and then NUMA node number.
Fields on the RDMA configuration info tab
There are twenty-four columns, so only the seven needed to identify a device and read its connection status are displayed by default. Turn on the rest in Column settings.
| Field | Default | Description |
|---|---|---|
hostname | Shown | Server name (host name) |
interfaceName | Shown | RDMA device name and port number (for example, mlx5_0:1) |
rdmaDevice | Shown | RDMA device name |
rdmaNetdev | Shown | Operating system network interface connected to the device |
rdmaLinkLayer | Shown | Link layer. InfiniBand or Ethernet |
rdmaRate | Shown | Link speed |
rdmaNumaNode | Shown | NUMA node number the device belongs to |
rdmaPort | Hidden | Port number |
rdmaDeviceModel | Hidden | Device model name |
rdmaDeviceType | Hidden | ASIC type of the device |
rdmaNetdevIp | Hidden | IP address per network interface |
rdmaVlanId | Hidden | VLAN ID |
rdmaMtu | Hidden | MTU of the RDMA port |
rdmaNetdevMtu | Hidden | MTU of the network interface |
rdmaPciBusId | Hidden | PCI bus address of the device |
rdmaBondMaster | Hidden | Bonding master interface |
rdmaDriverName | Hidden | Driver name |
rdmaDriverVersion | Hidden | Driver version |
rdmaFirmwareVersion | Hidden | Firmware version |
rdmaNodeGuid | Hidden | Node GUID |
rdmaPortGuid | Hidden | Port GUID |
rdmaSysImageGuid | Hidden | System image GUID |
rdmaSubnetPrefix | Hidden | Subnet prefix |
storageMount | Hidden | Connected storage mount |
The default sort is ascending by server name and then interface name. For details on the collection fields, see the server_rdma_inventory and server_numa_inventory category descriptions in the Server inventory collection items document.
When the table is empty
An empty table is explained in two ways: when collection did not happen at all, and when collection happened but there is no result matching the query conditions. Check the message first, then revert the query time and the filter conditions.
Common features
The System Information Inventory screens (File system operation info, NIC configuration info, Time synchronization info, OS Parameter info, and System configuration info) share the same query method.
-
Real-time query: Reloads the latest data periodically. The refresh interval differs by screen and is described in each screen's section. You can also pause the real-time query to check data at a specific point in time. However, OS Parameter info and System configuration info do not provide a real-time query.
-
Search: Enter a keyword in the search box to query only the items you want.
-
Filter: Add filter conditions to display only items for specific servers or statuses.
-
Column settings: Select the columns to display on the screen and adjust their order. The selected column configuration is saved in the browser and retained even after you refresh the page.
-
CSV download: Download the current query results as a CSV file.
-
Sort: Click a column name to change the sort to ascending or descending order.
Column labels and units
The column labels, units, and tooltip descriptions on each screen are displayed based on the collection metadata. The item names listed in each screen's field table are based on the collection fields and may differ from the column labels shown on the screen.
Real-time query is not supported
The System configuration info screen does not provide the real-time query among the common features above, because it is an inventory refreshed once a day. Search, filters, column settings, CSV download, and sorting can be used in the same way.
