Managing Host Devices

Managing Host Devices

Host management refers to monitoring management based on operating systems. The host management involves viewing device information, modifying device configurations, and modifying protocol parameters.

Hosts can be managed in agent or agentless mode.

  • The agentless mode features simplicity and ease-of-use. In this mode, you monitor hosts as the operating system administrator.
  • In agent mode, agents are running on hosts and provide comprehensive functions such as performance statistics collection and alarm reporting. Host agents can be remotely installed and upgraded.

Managing All Devices

You can search for host information using keywords and then check the information that you have found.

Procedure
  1. Choose Resource > Storage Subnet.

    NOTE:

    Resources that are added as hosts are used to implement Storage Network Analysis functions.

  2. In the navigation tree, choose Host.

    The page for searching for host information is displayed.

  3. Search for host information using the following keywords.

      When the number of disks associated with the database is 1, fitting will not be implemented for the response time indicator. When the number of disks associated with the database is larger than 1, the response time indicator is obtained by fitting the disk response time and IOPS. Therefore, the performance data of the disk response time and IOPS must be available in the selected period. Otherwise, there is no response time indicator of the disks associated with the database in the response time graph, and the legend is 0.

      • IOPS: compares the read and write throughput and redo write throughput of the database with those of the associated disks.
      • BindWidth: compares the read and write bandwidth and redo write bandwidth of the database with those of the associated disks.
      • CpuUsage: compares the CPU usage of the database with that of the host.
      NOTE:

      The disk redo write response time, redo write throughput, and redo write bandwidth are calculated when redo disks exist in the disks associated with the database. This indicator will not be displayed if no redo disks exist.

    7. In the DialogueWaitTimeTop5(Peak) performance graph, view the comparison of the five indicators with the maximum peak values among 16 indicators in the specified time range.
    8. In the upper right corner of DialogueWaitTimeTop5(Peak) and DialogueWaitTimeTop5(Mean), click to export the performance graphs.

      • To use the root cause function, an Oracle diagnostic pack license is required for the monitored database.
      • Command Step 2.10 to Step 2.11 must be executed when using the root cause function for each database instance. Otherwise, information about database instances cannot be collected.
    11. Run the following command.

      show parameter control_management_pack_access

      Check whether the value in the information of the returned result is DIAGNOSTIC or DIAGNOSTIC+TUNING?

      • Yes, go to Step 2.12.
      • No, run the following command alter system set control_management_pack_access='DIAGNOSTIC+TUNING' scope=both;.
    12. Click Root Cause.
