Original performance data is collected from different Network Elements according to the tasks created. Data management module performs overall management on the original performance data. By setting different parameters in the query pane, you can query the original performance data by measuring object and task.

Data management includes querying performance data by measuring objects, querying performance data by task and setting data security term.

4.3.1 Querying Performance Data by Measuring Object

This operation enables you to query the collected original data according to the set conditions. You can select device type, device name, measuring unit, measuring object, measuring entity and conditional expression to query the original performance data within the specified period.

I. Operation procedure

1) Select [Performance&Stat/Performance Data Management] or click on the toolbar to display the "Data Management" window as shown in Figure 4-3.

Figure 4-3 Querying performance data by measuring objects

2) Select "Query by Measuring Object" in the "Query Type" area.

3) Select the device type for data query from the "Device Type" drop-down list.

4) Select the device name for data query from the "Device Name" drop-down list.

5) Select the measuring unit for data query from the "Measuring Unit" drop-down list.

6) In the "Time Range" area, click <...> next to the "Start Time" and "End Time" edit boxes to specify the time range for the data to be queried.

7) Click <Measuring Object>, and then select measuring objects in the dialog box that appears, finally click <OK> to confirm the operation and close the dialog box.

4.3.2 Querying Performance Data by Task

This operation enables you to query the collected original data according to the set conditions. You can select device type, device name, task, measuring entity and condition expression to query the original performance data within the specified period.

I. Operation procedure

1) Select [Performance&Stat/Performance Data Management] or click on the toolbar to display the "Data Management" window as shown in Figure 4-3.

2) Select "Query by Task" in the "Query Type" area.

3) Select the device type for data query from the "Device Type" drop-down list.

4) Select the device name for data query from the "Device Name" drop-down list.

5) Select the measurement task for data query from the "Task" drop-down list.

6) In the "Time Range" area, click <...> next to the "Start Time" and "End Time" edit boxes to specify the time range for data to be queried.

7) Click <Measure Entity>. In the dialog box that appears, create a conditional expression, and then click <OK>.

8) In the “Data Management” window, click <Query> or <Apply>.

II. Parameter specification

[Device Type]: A device type supported by the data management function.

[Device Name]: After a device type is selected, all names of the devices of the type are displayed in the "Device Name" drop-down list.

[Task]: After a device is selected, all tasks are displayed in the "Task" drop-down list.

[Start Time]: Start time for the data querying. It should be earlier than the valid start time

[Measuring Entity]: Measuring entity for the data querying. It is related to the measuring unit selected when creating the performance measurement task.

Note:

z For the operations of creating a conditional expression, refer to 4.7.5 Creating a Conditional Expression.

z Click <Save> to save the query results in the form of .html or .csv. Click <Print> to print the query results. Click <Delete> to delete the records. Click <Close> to close the query window.

4.3.3 Setting Data Security Term

In order to ensure security of the saved performance data, you can set a time segment starting from the current date. The time segment ranges from 3 to 6 months. The performance data within this time range cannot be deleted.

I. Operation procedure

1) Select [Performance&Stat/Performance Data Management] from the main menu or click the corresponding shortcut button on the toolbar to display the "Data Management" window as shown in Figure 4-3.

2) Click <Security> on the lower part of the "Data Management" window to display the “Set Security Term” dialog box, as shown in Figure 4-4.

3) In the dialog box, select the security term.

4) Click <OK>.

II. Parameter specification

[Security Term]: A time segment backward from the current date (it ranges from three to six months). The data within this time range will be protected and cannot be deleted.
