Performance

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:

Global performance logging initiates at the chassis-level, carrying down performance logging functions to the module and interface levels. To begin global performance logging, see "Starting Global Performance Logging" section.
Module-level performance data enables, thereby also initiating interface performance logging. (Chassis performance logging does not necessarily enable.) For instructions to begin performance logging on a module, and all underlying interfaces, see the "Module Performance" section.
Performance logging on a specific interface begins, starting the collection of performance data for that interface only (not the parenting module or chassis). To begin interface-level performance logging, see the "Interface Performance" section.

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:

Module Performance

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:

Step 1 Right-click (on a relevant object icon in the Map Viewer window or from an object pick list) and choose Cisco Access Router Manager > Performance > (Module >) Performance. For information on which objects allow you to launch the Module Performance window, see "EM Windows".

The Module Performance window appears displaying the Performance tab.

Figure 8-1 Module Performance Window

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:

CPU Busy %—Percentage of CPU put to use for the selected module
Average (1 min)—Percentage of CPU being utilized averaged over a minute period for the selected module
Average (5 min)—Percentage of CPU being utilized averaged over five minute period for the selected module

Step 3 To start or stop module performance logging, click the appropriate performance logging button:

Click Start to begin performance logging for the selected module. Enabling performance logging allows for performance data gathering on a specific module. Performance polling occurs every 15 minutes. Performance data may then be stored for historical review in the Performance Manager, with exception only to CPU data.
Click Stop to terminate performance logging for the selected module. Disabling performance logging stops performance data from being gathered on the selected module.

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.

Interface Performance

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:

Step 1 Right-click (on a relevant object icon in the Map Viewer window or from an object pick list) and choose Cisco Access Router Manager > Performance > (Interface >)Performance. For information on which objects allow you to launch the Interface Performance window, see "EM Windows".

The Interface Performance window appears displaying the Performance (1) tab.

Figure 8-2 Interface Performance Window—Performance (1) Tab

Step 2 Select a chassis from the Chassis list box at left of the window, select a module from the Module list box, then select an interface from the Interface list box.

Current performance data for the selected interface displays to the right.

The General Information area displays the following:

Resets—Number of times the interface is internally reset
Transmitted Bandwidth Utilization—Percentage of transmitted bandwidth utilization. The percentage is calculated as packets per second divided by the speed of interface, averaged over the polling period (if performance polling is active).
Received Bandwidth Utilization—Percentage of received bandwidth utilization. The percentage is calculated as packets per second divided by the speed of interface, averaged over the polling period (if performance polling is active).

Note that Transmitted/Received Bandwidth Utilization will not calculate or display until after a performance logging poll (15 minutes) occurs and if performance logging is active for the interface.

The Packets/Octets Statistics area displays the following:

In Octets—Total number of packets received on the interface, including framing characters
Out Octets—Total number of packets transmitted out of the interface, including framing characters
In Bits/sec—Five-minute exponentially decayed moving average of input bits per second
Out Bits/sec—Five-minute exponentially decayed moving average of output bits per second
In Packets/sec—Five-minute exponentially decayed moving average of input packets per second
Out Packets/sec—Five-minute exponentially decayed moving average of output packets per second
In Unicast Packets—Total number of packets received by the layer which were not addressed as multicast or broadcast
Out Unicast Packets—Total number of packets transmitted by the layer which were not addressed as multicast or broadcast
In Multicast Packets—Total number of individual packets received by the layer addressed as multicast
Out Multicast Packets—Total number of individual packets transmitted by the layer addressed as multicast
In Broadcast Packets—Total number of data packets received by the layer addressed as broadcast
Out Broadcast Packets—Total number of data packets transmitted by the layer addressed as broadcast

If performance logging is enabled at the interface level or you do not wish to enable logging, skip Steps 3 through 5 and proceed to Step 6.

Step 3 To start or stop interface performance logging, click the appropriate performance logging button:

Click Start to begin performance logging for the selected interface. Enabling performance logging allows for performance data gathering on a specific interface. Performance polling occurs every 15 minutes. Performance data may then be stored for historical review in the Performance Manager, with exception only to CPU data.
Click Stop to terminate performance logging for the selected interface. Disabling performance logging stops performance data from being gathered on the selected interface for display in the Performance Manager.

For information on the Performance Manager, see the "Performance Manager" section.

If the Start or Stop button has previously been selected (i.e., performance logging started or stopped), it is available for selection, however, an action report displays indicating a failure because the performance logging action you selected is already initiated.

A window appears for you to confirm the performance logging action.

Step 4 Click Yes to continue or No to cancel the operation.

An Action Report window appears confirming that the performance logging action was successful.

Step 5 Click Close to close the Action Report window.

Step 6 Click the Performance (2) tab, if required.

Performance Manager

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:

Identify all Monitored Attributes on a selected managed object
Identify all time periods configured for sampling each monitored attribute
Identify all summary methods configured for selected monitored attributes and selected summary periods
View historical performance data over a requested period of time (as a line chart, bar chart or as a table display)
Print performance data to a printer
Save/export performance data to a file, for subsequent analysis and processing, for example, using a spreadsheet application

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:

Global performance logging initiates at the chassis-level, carrying down performance logging functions to the module and interface levels. To begin global performance logging, see "Starting Global Performance Logging" section.
Module-level performance data is enabled, thereby also initiating interface performance logging. (Chassis performance logging is not necessarily enabled.) For instructions to begin performance logging on a module, and all underlying interfaces, see the "Module Performance" section.
Performance logging on a specific interface begins, starting the collection of performance data for that interface only (not the parenting module or chassis). To begin interface-level performance logging, see the "Interface Performance" section.

To begin using the Performance Manager window, proceed as follows:

Step 1 Right-click (on a relevant object icon in the Map Viewer window or from an object pick list) and choose Tools > Performance Manager. For information on which objects allow you to launch the Performance Manager window, see "EM Windows".

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.

Figure 8-11 Performance Manager Window—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.

Click the Now check box to view the data from the selected start date to the current time. By selecting this option, you do not have to update the end date and time fields.
Enter the End date and time in the Time Period panel.

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:

Total—Totals all values gathered in the summary period
Average—Takes the average of all values gathered in the summary period
Trough—Presents the lowest value received over the summary period
Peak—Presents the highest value received over the summary period
LogicalOR—Displays either 1 or 0. This is typically used for status flags. Some attributes may have only two potential values (such as, true or false; yes or no; 1 or 0). When summaries are generated from values such as these, and the logicalOR rule is used, the summarized value is 1 if any value in the summary interval is 1. If all values in the summary interval are 0, then the summarized value is 0.

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.
