OS Parameter information
Home > Select Project > Labs > OS Parameter information
OS Parameter information is a Labs feature that lets you query the kernel and system parameter values of multiple servers in a project on a single screen. Instead of connecting to each server one by one to check the sysctl result, you can view the parameters and setting values of the network, file system, and kernel areas gathered per server. It is a screen for operators who compare configuration differences between servers or check kernel settings that can cause performance problems. It is read-only and does not provide a feature to change values.
How to access the Labs menu
OS Parameter information is included in the Labs menu and appears after Time synchronization information in the Labs menu. For how to access Labs features and the precautions, see the Labs document.
Windows does not collect kernel and system parameters, so it is excluded from the query targets.
Query items
| Field | Description |
|---|---|
oname | Server name (host name) |
os | Operating system type |
category | Area the parameter belongs to (for example, net, fs, kernel) |
parameter | Parameter name (for example, net.ipv4.tcp_keepalive_intvl) |
value | Current value of the parameter |
The default sort is ascending by operating system, server name, area, and parameter name. For more information about the collected fields, see the infra_os_parameter category description in Server metrics V2.
Setting the query range
Unlike the other system information screens, OS Parameter information does not provide a real-time query. The parameter values are collected every hour, so you must specify a range of at least two hours for the values to be displayed.
-
When you first enter the screen, the last two hours are queried.
-
In the time selection, choose one of the last 2 hours, 6 hours, 24 hours, 3 days, or 7 days, or specify the range directly.
-
If you specify a range shorter than two hours, a message is displayed and the query does not run.
Change history query to be provided
On the current screen, you can query only the parameter values collected in the specified range. The change history query feature, which shows when and to what value a parameter changed, is scheduled for September 2026.
Common features
The four screens of the System Information Inventory (File system operation info, NIC configuration info, Time synchronization info, and OS Parameter 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 does 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 not supported
The OS Parameter information screen does not provide the real-time query among the common features above. Search, filter, column settings, CSV download, and sort can be used in the same way.
