Compare Kernel Parameters Across Multiple Servers
- This procedures describes how to compare kernel enabled parameters through the /etc/system file across multiple servers in one report.
- q-Status kernel enabled parameters is collected by retaining a copy of the /etc/system file.
Step Action Description 1 In the "Basic" Icon set, from "package/kernal"
Icon select Kernel
Move mouse cursor over the "Kernel" text in the "Basic" Icon set "package/kernal" Icon. The the text will enlarged. Click the mouse. The single host selection page will be displayed with a "Assigned Kernel Parameters (/etc/system)" Title.
2 Select Servers Navigate through the host selection page, filtering or ordering server selection till the proper Hostname appears. Using multiple checkboxes () select up to five servers for comparisons and click "Display /etc/system" submit button at the bottom of the mult-host selection page. The "Assigned Kernel Parameters" report will be displayed.
The "Assigned Kernel Parameters (/etc/system)" report will diplay each parameter enabled in the /etc/system file for each server in alphabetical order as a single row.
Each column header represents a server. It display the hostname with the kernel parameter in the column rows. Each parameter row follows a color key notation as discribed in the table below:
Light Gray No Discrepancy none Pink Revision Discrepancy Bold Yellow or blank Missing Discrepancy none 3 Optionally Use Discrepancy
The "Assigned Kernel Parameters" report has a built in discrepancy engine. This is accessed through the pulldown at the top of the page:
Selecting any of these options will reprocess the "Assigned Kernel Parameters" report to filter the selection.
The definitions of the pulldown selections are described in the following table:
Definition Full Display Lists all kernel comparison parameters Discrepancy Only Lists kernel comparison parameters which are either have a parameter conflict or missing. Version Conflicts Only Lists kernel comparison parameters have a parameter conflict only. Missing Only Lists kernel comparison parameters which are missing. 4 Optionally highlight <hostname>
for display server /etc/system file.
Move mouse over the server hostname.
When highlighted, click mouse to display the "/etc/system raw file" windows popup of the RAW /etc/system file collected by q-Status for that server.
