Setting Per-Second Performance Monitoring for Converged Services

Prerequisites

• A storage pool has been created.
• If per-second performance monitoring is enabled, you need to disable the function and delete the configuration information by referring to 2 before modifying parameters.

Context

Before per-second performance monitoring is enabled, there is limited space for storing performance monitoring data. As a result, the data can only be stored for a short period of time at a coarse granularity. After this function is enabled, performance monitoring data is written to the mounted namespace and can be stored for a longer time at a finer granularity.

Procedure

1. Choose Settings > Monitoring Settings > Per-Second Performance Monitoring.
2. (Optional) If per-second performance monitoring is enabled, disable it and delete the configuration information before modifying parameters.
   1. Click Modify in the upper right corner of the page.
   2. Set Per-Second Performance Monitoring to Disable and click Save.
   3. In the dialog box that is displayed, select Delete per-second performance monitoring configurations and performance data and click OK.
   4. Confirm your operation as prompted.

3. Click Modify in the upper right corner of the page.
4. Set per-second performance monitoring.
   Set basic information about per-second performance monitoring. Table 1 describes related parameters.

   Table 1 Per-second performance monitoring parameters

   Parameter	Description
   Per-Second Performance Monitoring	Select whether to enable per-second performance monitoring. Enable: Performance monitoring data is written to a specified namespace. Disable: Performance monitoring data will no longer be written to the namespace. If you select Delete per-second performance monitoring configurations and performance data, the per-second performance monitoring data that has been saved to the namespace will be deleted (unable to be restored) and can no longer be viewed. Otherwise, the data that has been saved to the namespace will not be deleted. NOTE: If per-second performance monitoring has never been enabled, a message will be displayed on the top of DeviceManager: "The system detects that per-second performance monitoring is not enabled. Enabling this function helps you analyze performance more accurately. Do you want to enable the function? After enablement, this prompt will be automatically cleared."
   Storage Pool	Select a storage pool where the per-second performance monitoring data is to be stored.
   Namespace	Determine a name for the namespace to be mounted for the storage of per-second performance monitoring data. NOTE: The character string provided in the text box is the prefix of the namespace.
