Performance Alarm Threshold Management

Performance alarm threshold management enables you to set threshold values for the measuring entities.

For each combination of device type, device, measuring unit, measuring object and measuring entity, upper threshold value and lower threshold values can be set. In the process of collecting performance data, the system will automatically check the threshold for performance data set with alarm thresholds. If the performance data exceeds the threshold, performance alarms will be generated and sent to the alarm module and finally reported to you. There are recovery alarms corresponding to the performance alarms.

Performance alarm threshold management involves querying, adding, deleting and modifying performance alarm threshold.

4.5.1 Querying Performance Alarm Threshold

This operation enables you to query performance alarm threshold records.

I. Operation procedure

1) Select [Performance&Stat/Threshold Management] or click on the tool bar to display the "Threshold Management" window as shown in Figure 4-6.

2) In the "Device Type" drop-down list, select the type of the device for which the performance alarm threshold is to be queried.

3) In the "Device Name" drop-down list, select the name of the device for which the performance alarm threshold is to be queried.

4) In the "Measuring Unit" drop-down list, select the measuring unit for which the performance alarm threshold is to be queried.

5) In the "Measuring Object" drop-down list, select the measuring object for which the performance alarm threshold is to be queried.

6) In the "Measuring Entity" drop-down list, select the measuring entity for which the performance alarm threshold is to be queried.

7) In the alarm threshold list, observe the performance alarm threshold information.

II. Parameter specification

[Device Type]: All device types supported.

[Device Name]: After one device type is selected, all devices of the type will be available in the "Device Name" drop-down list.

[Measuring Unit]: After one device is selected, all measuring unit supported by the device will be available in the "Measuring Unit" drop-down list.

[Measuring Object]: It is the measuring object for which performance alarm threshold is to be queried.

[Measuring Entity]: It is the measuring entity for which performance alarm threshold is to be queried.

4.5.2 Adding a Performance Alarm Threshold

This operation enables you to add performance alarm threshold for the measuring entities. Depending on the alarm threshold and alarm levels added, corresponding alarms will be generated.

I. Operation procedure

1) Select [Performance&Stat/Threshold Management] from the main menu or click on the toolbar to display the "Threshold Management" window as shown in Figure 4-6.

2) In the "Device Type" drop-down list, select the type of the device for which the performance alarm threshold is to be added.

3) In the "Device Name" drop-down list, select the name of the device for which the performance alarm threshold is to be added.

4) In the "Measuring Unit" drop-down list, select the measuring unit for which the performance alarm threshold is to be added.

5) In the "Measuring Object" drop-down list, select the measuring objects for which the performance alarm threshold is to be added.

Chapter 4 Performance Management 6) In the "Measuring Entity" drop-down list, select the measuring entities for which

performance alarm threshold is to be added.

7) In the "Threshold" pane, enter values for "High Threshold" and "Low Threshold", and then select "Alarm Level".

8) In the "Date Time" pane, click <...> next to the "Start Time" and "End Time" to set start time and end time for the performance alarm threshold.

9) Click <Add> and then observe the newly added performance alarm threshold record in the performance alarm threshold list.

II. Parameter specification

[High Threshold]: Upper threshold of the performance alarm threshold. In case it is crossed, alarms will be generated.

[Low Threshold]: Lower threshold of the performance alarm threshold. In case it is crossed, alarms will be generated.

[Alarm Level]: It is of enumerated type. The following options are provided: critical, major, minor and warning.

[Start Time]: Start time for threshold value checking. It should not be earlier than the current time.

[End Time]: End time for threshold value checking. It should not be earlier than the start time.

4.5.3 Modifying a Performance Alarm Threshold

This operation enables you to modify performance alarm threshold of the measuring entity. Among the parameters, start time, end time, upper limit, lower limit and alarm level can be modified. After the modification, the alarms will be reported according to the newly-set upper/lower limit and alarm level.

1) Query performance alarm threshold following the steps given in 4.5.1 to list all performance alarm threshold records meeting the conditions in the result output area.

2) Select one record to be modified in the threshold list.

3) On the "Threshold" pane, enter new values for "High Threshold" and "Lower Threshold", and then select new "Alarm Level".

4) On the "Time Range" pane, click <...> next to the "Start Time" and "End Time" edit boxes and then modify the start time and end time for performance alarm threshold.

5) Click <Apply>.

4.5.4 Deleting a Performance Alarm Threshold

This operation enables you to delete performance alarm threshold from the measuring entities. After the deletion, no performance alarms will be generated for the measuring objects.

1) Query performance alarm threshold following the steps given in 4.5.1 to list all performance alarm threshold records meeting the conditions in the result output area.

2) Select one or more records to be deleted in the threshold list.

3) Right click it and then select [Delete].

4) In the confirmation dialog box, click <OK>.
