6 Managing Statistics

This chapter describes how to view statistics for the hardware and software components of Oracle Communications Service Broker Netra 6000 High Availability Manager (HA Manager).

About Statistics

HA Manager provides performance statistics that you can use to monitor the performance of HA Manager's components. For example, you can monitor the percentage of time that a hardware component used the CPU and the amount of server memory this component consumes.

You can view statistics in real-time, review them at any point within the previous 100 minutes, and save the statistics to a file.

HA Manager gathers statistics on the following components:

• System, including all installed chassis, slots, and servers

• Individual chassis, including all installed slots and servers

• Individual slots, including all installed servers

• Individual servers

About the Statistics Window

Figure 6-1 shows the Statistics window in the Administration Console.

Figure 6-1 Statistics Window

The Statistics window provides information about the performance metrics described in Table 6-1. To ensure that the latest statistics are available to view, HA Manager periodically updates the Statistics window. See "Setting the Statistics Window Refresh Rate" for more information about setting up the frequency of the window updates.

Table 6-1 Statistics Window Fields

Field	Description	Applicable to
Element	Specifies the name of a component. Each component is represented by a node that you can expand or collapse.	Blade Signaling Servers Processing Servers
Average CPU	Specifies the average percentage of CPU capability that the component used.	Blades Processing Servers
Active Sessions	Specifies the number of HA Manager active sessions handled by the component.	Signaling Servers Processing Servers
Heap Usage	Specifies the amount of server memory, in megabytes, that the component used.	Blades Signaling Servers Processing Servers
Work Manager Queue	Specifies the number of threads in the pool.	Signaling Servers Processing Servers
Event Rate	Specifies the number of events created by an individual protocol adapter.	Processing Servers
Up Time	Specifies the amount of time a server has been running.	Signaling Servers Processing Servers

Setting the Statistics Window Refresh Rate

HA Manager periodically updates the Statistics window with the latest statistics. The default refresh rate is 1.5 seconds. You can change this rate using the Settings dialog box.

To change the Statistics window refresh rate:

1. In the System Administration Console, click the System tab.

2. On the top right corner of the window, click the Settings icon.

   
   

   The Settings dialog box appears.

3. In the Refresh list, select one of the following refresh rates:

   • Slow: Every 3 seconds

   • Normal: Every 1.5 seconds

   • Fast: Every 0.5 second

Viewing Statistics History

In addition to viewing the statistics in real-time, you can view statistics at any point within the previous 100 minutes. For example, you can view statistics gathered an hour earlier.

To view statistics history:

1. In the System Administration Console, click the System tab.

2. Click the Statistics subtab.

3. At the bottom of the Statistics window, move the Timer slider to the specific point in time at which you want to view the statistics. Figure 6-2 shows the bottom of the Server Console with the Timer Slider circled at a point 48 minutes and 43 seconds prior to the present time.

   HA Manager updates the data in the Statistics window.

Exporting Statistics

You can export the statistics gathered during the last 100 minutes to a file and download this file to a local drive. You can use third party software to view the statistics file and manipulate the statistics data.

You can specify the information to be included in the file as follows:

• Export statistics for a specific metric.

• Export statistics for a specific component and specify metrics to be exported for this component.

Exporting Statistics by Metric

You can generate a file containing the statistics for a specified metric. In this case, the first column of the file contains timestamps of when the measurements were taken for the specified metric. Other columns represent the components for which the statistics were gathered.

Figure 6-3 shows an example of a file opened in a spreadsheet program. The file contains statistics for CPU usage.

To export statistics for a specific metric:

1. In the System Administration Console, click the System tab.

2. Click the Statistics subtab.

3. If there is no data in the Statistics window, click Start Monitoring to start gathering statistics.

   Note:

   If there is no data, the Export Statistics button is disabled.

4. Click Export Statistics.

   The Export Statistics dialog box appears.

5. Click the By Metric tab.

6. In the Metric list, select the metric whose statistics you want to export.

7. Click Export.

   HA Manager generates the file and displays the Download File dialog box.

8. Click the statistics' file link to download the file.

9. Specify where on your local drive you want to save the file.

   HA Manager downloads and saves the file to the specified location.

10. To close the Download File dialog box, click Close.

Exporting Statistics by Component

You can generate a file containing the statistics for a specific component. In this case, the first column of the file contains timestamps of when the measurements were taken for the specified component. Other columns represent the metrics for the specified component.

Figure 6-4 shows an example of the .csv file that contains statistics on CPU usage and active sessions handled by Chassis 0.

To export statistics for a specific component:

1. In the System Administration Console, click the System tab.

2. Click the Statistics subtab.

3. If there is no data in the Statistics window, click Start Monitoring to begin gathering statistics.

   Note:

   If there is no data, the Export Statistics button is disabled.

4. Click Export Statistics.

5. Click the By Element tab. In the

6. In the Element list, select the component whose statistics you want to export.

7. Select the metrics that you want to export for the specified component.

8. Click Export.

   HA Manager generates the file and displays the Download File dialog box.

9. Click the statistics file link to download the file.

   Specify where on your local drive you want to save the file.

   HA Manager downloads and saves the file to the specified location.

10. To close the Download File dialog box, click Close.
