There are two performance options in the EM: (1) the interface performance windows and (2) the Cisco EMF Performance Manager application. The Performance Manager displays historical data as well as current data in the form of a line chart, bar chart, or table. In order to enable data collection for historical purposes, performance data must be available to the Performance Manager. Data collects and archives to the Performance Manager if one of the following occurs:
The interface performance windows display only current data in a raw numerical format and do not require formal data collection.
The Performance chapter covers the following areas:
The Module Performance window allows you to start or stop performance logging on a selected module, specifically the interfaces within that module. The Module Performance window also displays the current CPU usage statistics for selected modules.
To start or stop module performance logging, or to view CPU usage data, proceed as follows:
The Module Performance window appears displaying the Performance tab.
Step 2 Select a chassis from the Chassis list box at left of the window, then select a module from the Module list box.
Tip Line cards are listed, as well as supporting modules in the Module list box. Although line cards and supporting modules are listed, no performance data is available for these modules. |
Selecting a module provides performance data for that particular module. The values which display relate to CPU performance, so modules without a CPU display the same value as the CPU card in the chassis. Data in the CPU Usage area displays as follows:
Step 3 To start or stop module performance logging, click the appropriate performance logging button:
An Action Report window appears confirming that the performance logging action was successful.
Step 4 Click Close to close the Action Report window.
Step 5 Choose File > Close to close the Module Performance window.
You can view historical performance data in the Performance Manager if module performance logging was initiated. For information on how to use the Performance Manager application, see the "Performance Manager" section.
The Interface Performance window allows you to start or stop performance logging on a selected interface.
Starting performance logging allows for the gathering of performance data on the selected interface. Interface performance polling occurs every 15 minutes. Performance data is then stored for historical review. You can view historical performance data in the Performance Manager. For information on the Performance Manager, see the "Performance Manager" section.
The Interface Performance window also displays the current performance statistics for selected interfaces. If the EM provides technology-specific performance data for the interface you are reviewing, you may view further performance parameters on the interface.
To start or stop interface performance logging, or to view performance parameter data, proceed as follows:

An important component of efficient network management is the ability to collect and analyze performance information in a large network of many devices. This performance information can assist you to pro-actively manage your network elements, and troubleshoot network problems.
This section describes the Cisco EMF Performance Manager application that is used in conjunction with the EM to view performance statistics from the routers managed on your network.
Performance Manager is a powerful, flexible tool that enables you to view general and performance specific attributes in one application and in a variety of formats (for example, graphs and tables). You define the attributes or parameters, choose the objects you want to view, select the date and time of the view, and set the summary interval.
Performance Manager collects data for all different technologies on an interface. For example, if you want to view Performance Manager data for an ATM interface, performance attributes are listed for generic and SONET technologies because both apply to ATM interfaces.
The Performance Manager window allows you to:
Note For further information on the Performance Manager, see the Cisco Element Management Framework User Guide Release 3.2. |
Performance Manager collects historical performance data for interfaces. You can only view performance information in the Performance Manager if performance logging is switched on using the following methods:
To begin using the Performance Manager window, proceed as follows:
You cannot not open the Performance Manager window when multiple objects are selected (the menu options to open the EM windows are grayed out). Available menu options are available from a site object containing the required objects if you should need to launch additional windows.
The Performance Manager window appears displaying the Line Chart tab.
Note Cisco EMF provides a command line utility (history Admin) that allows mass export of performance history data. For further information, see the Cisco Element Management Framework User Guide Release 3.2. |
The monitored attributes list at the left of the window allows you to select the specific attribute you wish to view performance information for. The fields in this list change, depending upon the type of interface that you launched Performance Manager from. For example, if your selected interface is an ATM line card, you will be able to select all the performance fields that can be found on the generic, ATM, and SONET performance windows. These technologies apply to ATM line cards, therefore all performance information for the technologies are listed in the Performance Manager.
Step 2 Choose the attribute you wish to monitor in the Monitored Attributes panel. You can choose multiple attributes in a list by holding down the Shift key and then selecting the first and last attributes in the list. You can choose multiple individual attributes by holding down the Ctrl key and clicking on individual items. Only the first selected attribute, however, is shown in the line chart or bar chart. The table display tab shows all selected attributes.
Step 3 Set the start date and Time in the Time Period panel.
a. Enter the date on which you want to begin viewing performance data in the Start Date entry boxes. The format must be mm/dd/yyyy.
b. Enter the time you want the performance data to start on in the Start Time data entry boxes. The start time uses the 24 hour clock notation.
Step 4 Set the End date and time in the Time Period panel. You have two options when setting the end date. Perform one of the following actions.
a. Enter the date on which you want to stop viewing performance data in the End Date entry boxes. The format must be mm/dd/yyyy.
b. Enter the time you want the performance data to stop on in the End Time data entry boxes. The end time uses the 24 hour clock notation.
Step 5 Choose the summary interval from the drop down list in the Summary area. The summary interval is the period of time over which the rule is applied. This varies according to the attribute selected. You can choose from the Raw option, which displays performance data in its most detailed format, not summarized.
The performance information corresponds to the attributes' raw values. If you choose a summary period, the information is displayed according to the summary rule. No summary period is associated with raw data.
When you choose Raw, the bar chart view is sometimes not available, and the Summary Rule option is grayed out.
Step 6 Choose the appropriate option from the Rule drop down list. This gives you the option to view data summarized according to various rules as defined by the history storage criteria as follows:
The Rule option is not available when the option to view raw data is chosen.
Step 7 Click Refresh. The Refresh button is grayed out when not available. The Refresh button is available for selection when Now is selected, or when any criteria has changed and you have moved the cursor away from the changed value by clicking the Tab key or by using the mouse.
The performance information corresponds to the attributes' value returned during the raw sampling period. When a summary period other than raw is selected, the information appears according to the summary rule.
In some circumstances (possibly due to the EM being shut down or a heavy network load), polls can be missed. Performance Manager deals with this problem by displaying missed polls in red. The missed poll value is replaced by the last valid value collected. Performance Manager graphs and charts also indicate when an attribute started and stopped being polled due to history storage criteria being added, edited or removed. Start and stop polling events are shown in charts and tables. The start polling events point is shown in green, and the stop polling events point is shown in red.
A polling events key is displayed for selection.
The performance information appears as a line chart by default. You can view performance information as a line chart, a bar chart (except when the raw option is selected from the Interval drop down list) or as a table display by selecting the corresponding tab. The following table lists brief descriptions of each of the views available.
Table 8-1 Interface Types and Performance Windows
Step 8 Click the appropriate tab to review performance information in a different view as needed.
The following section describes how to perform various tasks with the data the Performance Manager displays. When you finish using the Performance Manager, choose File > Close to close the Performance Manager window.
You can zoom in, zoom out and move around the displayed charts using the key presses detailed in the following table. You must first select the chart before using the key presses detailed.
You can print performance statistics from the Performance Manager, either as a chart or as a table. A chart prints out the information which can be seen in the window, and a table prints out all of the performance statistics in a plain text format.
The output is printed by the default printer set up on your network.
The Performance Manager window appears displaying the Line Chart tab (see Figure 8-11).
Step 2 Choose the File > Print, then select the desired option, either As Chart or As Table.
Performance data is stored in the Cisco EMF database. It is not exported to ASCII file by default. To save performance data, follow these steps:
The Performance Manager window appears displaying the Line Chart tab (see Figure 8-11).
Step 2 Perform one of the following actions:
The File Chooser window appears. The left-hand panel displays the directories and the right hand panel displays the files. Use the scroll bars to locate the desired file.
Step 3 Click Filter to expand the list of options.
Step 4 Choose the file.
The full path name of the selected file is displayed in the File Filter box, as well as the Choice box. You can save the data to a new location or to a new file. Type in the new names as required in the Choice boxes.
Step 5 Click Apply to save the file or Cancel to return to the Performance Manager window.
Collected data is archived each day. The applied file name is generated automatically using the format mm-dd-yyyy.log. When entries are archived, they are purged from the database. By default, only raw data is archived.
If more than one purge is carried out in a day, the original log file is overwritten and the information stored is lost. After a purge, only the information in the current sample period is available for display.
Cisco EMF contains a utility called historyAdmin. HistoryAdmin enables you to selectively export performance data for groups in an automated manner.
Note For further information on archiving-related information, see the Cisco Element Management Framework User Guide Release 3.2. |
Performance data can be exported for use in other applications.
To export performance data, follow these steps:
The Performance Manager window appears displaying the Line Chart tab (see Figure 8-11).
Step 2 Perform one of the following actions:
The File Chooser window appears. The left-hand panel displays the directories and the right hand panel displays the files. Use the scroll bars to locate the desired file.
Step 3 Click Filter to expand the list of options.
Step 4 Choose the file.
The full path name of the selected file is displayed in the File Filter box, as well as the Choice box. You can save the data to a new location or to a new file. Type in the new names as required in the Choice boxes.
Step 5 Click Apply to save the file or Cancel to return to the Performance Manager window.
