Checking the Operating System Logs

Checking the Operating System Logs

This section describes how to periodically check the operating system logs so that you can understand the operating system running status.

Reference Standard

  • Windows

    No error information exists in Event Viewer.

  • Linux

    No error information exists in the operating system logs.


  • Windows
    1. Log in to the Windows operating system as the Administrator user.

      If security hardening has been completed for the Windows operating system, log in to the server as the SWMaster user.

    1. Choose Start > Administrative Tools > Event Viewer.
    2. In the window that is displayed, view the event log information to check whether there is any exception that affects the running of the system.

      For details about how to use the event viewer, see the operating system's Help or user manual.

  • Linux
    1. Log in to the Linux operating system as the root user.
      • If the Linux operating system is hardened, you need to remotely log in to the server as the ossuser and switch to the root user.
      • In the two-node cluster scenario, this operation must be performed on both the active and standby servers.
    2. Run the following command to go to the directory for storing the log files:

      # cd /var/log

    3. Run the following command to check whether the error information exists:

      #grep error messages*

      • If the error information does not exist, no information is displayed after the command is executed.
      • If the error information exists, all errors in the file are displayed.

      You can run the following command to view all operating system logs, that is, files starting with messages (including error and non-error).

      #more messages*
