In Net Inspector WorkGroup and Enterprise Edition (which integrate the Performance Manager functionality) managed objects are polled by a Performance Manager polling engine by default (as opposed to the Net Inspector LITE Edition, where polling is performed by the Net Inspector Server itself). In such configuration, the performance statistics of managed objects are not displayed in the device Properties window.
Instead, you can view more detailed device performance statistics with history in the Performance Statistics window, as described in this section.
Note: The Performance Statistics window is accessible only if MG-SOFT Performance Manager is installed and integrated with MG-SOFT Net Inspector application (i.e., in Net Inspector WorkGroup and Enterprise Edition).
1. Open the map that contains the managed object(s) you want to view the properties of by expanding the hierarchical map tree in the Explorer window (View / Explorer), selecting the relevant map and choosing the Open pop-up command (Figure 47).
2. A new tab opens in the Maps window, displaying the managed objects (and submaps if any) contained in the selected map.
3. To open the Performance Statistics window and view the performance data of the selected managed object, select a managed object and choose the Show Performance Statistics pop-up command (Figure 72).
Figure 72: Opening Performance Statistics window for the selected device
99 4. The Performance Statistics window appears (Figure 73).
Figure 73: Viewing device performance statistics
The Performance Statistics window is a Java-based web browser used for viewing the performance web page for the selected managed object directly in Net Inspector application. The device performance web page is generated by the Performance Manager polling engine that polls that device (when MG-SOFT Performance Manager and MG-SOFT Net Inspector applications are integrated). The device performance web pages include the following statistics (current data and history): device response time and packet loss rate and for SNMP devices (depending on the type) also network interface statistics, resources utilization statistics, running processes statistics, running services statistics, Cisco VoIP statistics, etc.
To view more detailed graphs and tables for any monitored metric, click on its graph/chart in the device performance page.
For more information about device performance web pages, please consult the Net Inspector Performance Manager User Manual, section Viewing Device Performance Data.

10 VIEWING CHARTS
Net Inspector lets you monitor values of some important numerical variables (e.g., CPU load, memory usage, storage utilization, interface utilization, etc.) collected from one or more devices in charts. Charts display lines that show how the values of selected variables change over time. Charts are configured by administrators and maintained by the Net Inspector Server. Network operators can connect to Net Inspector Server and view pre-configured charts in Net Inspector Client.
This document describes only how to view charts containing data collected by Net Inspector Server itself (built-in polling engine). For devices that are polled by Net Inspector Performance Manager polling engines, more detailed performance graphs are available. For details about the latter, please consult the Net Inspector Performance Manager User Manual, section Viewing Device Performance Data.
1. Select the Tools / Server Settings command and click on the Chart Panel to view the list of the existing charts (Figure 74).
Figure 74: Selecting a chart from the Chart Panel dialog box
2. Select the chart you want to view in the Chart Panel and click the Open button.
3. A new tab opens in the Maps window, displaying the selected chart (Figure 75).
4. The graph lines show how the values (Y-axis) collected from the managed object(s) changes in time (X-axis). The chart is automatically updated when the new values are retrieved. How frequently the chart is updated depends on the polling interval set in the polling profile assigned to the source objects.
5. See the graph legend displayed at the bottom of the chart, showing the colors of graph lines and accompanying objects (in square brackets) from which the values are being retrieved as well as the names of variables. The units in which variables are displayed are shown in brackets on the vertical axis.
101 6. To see individual retrieved values depicted as scatter marks along the graph line,
right-click inside the chart tab and select the Show Point pop-up command. Place your mouse pointer over a scatter mark to see its details (Figure 75), i.e., the managed object the value was retrieved from (in brackets), the variable name (e.g., CPU1), the date and time of retrieving the value, and the value itself (e.g., 51).
7. If present, use the horizontal scrollbar at the bottom of the chart, to move along the time line (X-axis).
8. Use your mouse wheel to zoom in and out of the chart. To view the entire chart, right-click inside the chart tab and select the Fit to Page pop-up command.
9. To view the chart properties (a list of source objects, monitored variables, etc.), select the Properties pop-up command that opens the chart properties dialog box.

10. To open and view another chart, repeat the procedure described in step 2. To close the Chart Panel dialog box, click the Close button at the bottom of this dialog. This will not close the charts displayed in the Maps window.
11. To remove the chart tab from the Maps window, right click the tab symbol in the Maps window and select the Close pop-up command (Figure 76).

11 APPENDIX: ABOUT USERS, ACCESS RIGHTS AND USER VIEWS
Each Net Inspector user account has certain access-rights assigned. User accounts have also one or more user views assigned. User views differ in respect to what objects they include (display). The table below shows the user account types, corresponding access rights and user views:
Account type Access rights User View (Typical)
Administrator unlimited unlimited (includes all objects) Operator limited to managing alarms limited to a part of the network Guest limited to monitoring (viewing) alarms limited to a part of the network
For more information about user accounts and user views, please consult the Net Inspector Client Reference Manual.
