This chapter describes the interface performance windows in which you can view real-time, current performance information within 10-second polled intervals for interfaces and line cards. This chapter also describes how to access CDM windows that display historical performance data.
Performance polling collects historical data and occurs over a specified time period. Current performance data that you can view on the specific interface performance windows is live; that is, the interface performance windows display what the interface is doing at that moment.
Viewing Current Performance Data in the Interface Performance Windows
This section describes the interface performance windows that are specific to an interface and that display current, live data for that interface. This section includes the following topics:
You can see how busy the CPU of an NI card is at any given time in the Module Performance window. For example, you may be issuing a lot of SNMP read/write operations on a particular chassis. The load on the CPU of the NI card for that chassis immediately increases; this load on the CPU is reflected in the Module Performance window.
Complete the following steps to open the Module Performance window:
Step 1 From the Physical view, right-click the NI card whose CPU performance you want to view to access the object menu.
The Module Performance window opens. (See Figure 8-1.)
Figure 8-1 Module Performance Window
Step 3 Click Start in the Performance Logging area to initiate performance logging; click Stop to end performance logging.
The Module Performance window displays the same information as the IOS command:
sh processes | include CPU
The Module Performance window has one tab, Performance. The CPU Usage area displays the following information about the NI card CPU.
CPU Busy %—Displays the current CPU usage.
Average (1 min)—CPU usage averaged over last 1 minute.
Average (5 min)—Displays the CPU usage averaged over last 5 minutes.
Viewing xDSL Interface Performance Data
The Interface Performance window displays generic performance data for the selected interface. This section applies to viewing line card interface performance data for interfaces such as FlexiDMT and FlexiCAP.
To open the Interface Performance window, complete the following steps:
Step 1 From the Map Viewer window, within the Physical view, right-click the chassis for which you want to view interface performance data.
Step 2 Choose Cisco DSL Manager > Interface > Performance > XDSL > Generic from the object menu.
The Interface Performance window opens to the Performance (1) tab. (See Figure 8-2.)

Viewing Historical Performance Data
This section describes how to use the Performance Manager window to view historical data as well as current data in the form of a line chart, bar chart, or table. This section also describes how to view DS3/E3 or OC-3 interface performance data and how to view ATM over ADSL over DMT interface performance data.
Setting the Chassis to Performance Logging On State
Before you can view historical performance data, you must set the state of the chassis to performanceloggingon state, which begins the polling process. Complete the following steps to start performance logging:
Step 1 Right-click the chassis object or objects on which you want to set performance logging on.
The Chassis Configuration window opens. (See Figure 8-24.)
Figure 8-24 Chassis Configuration Window
Step 3 Click Start in the Global Performance Logging area on the lower right side of this window.
The Action Report window opens to inform you whether the logging process has successfully started or failed. If a failure occurs, it is often because performance logging has already been set to on.
Note Before you can monitor performance data on any interface, you need to set global performance
logging to on in the Chassis Configuration window. Right-click the chassis (DSLAM) object whose
interfaces you want to monitor, and then choose Cisco DSL Manager > Chassis > Configuration.
Click Global Performance Logging in the Chassis Configuration window to start logging
performance data.
You can open the Performance Manager within the Map Viewer window. After you open the Map Viewer window, complete the following steps:
Step 1 In the Map Viewer window, within the Physical view, right-click the DS3/E3 or OC-3 interface whose performance you want to view.
Step 2 Choose Tools > Performance Manager from the object menu.
The Performance window opens to the Line Chart tab and displays historical performance data about the DS3/E3 interface. (See Figure 8-25.)
The DS3/E3 Interface Performance window consists of three left areas, and three tabbed sections at right. Choose the parameters you want from the left areas.
Step 3 From the Monitored Attributes list, choose the attribute you want to monitor. You can choose multiple contiguous 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. Information for all selected attributes is shown in the table display. Only the first selected attribute is shown in the line chart or bar chart.
In the Time Period area, choose the time parameters.
Step 4 Set the Start Date. 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.
Step 5 Set the Start Time. Enter the time you want the performance data to start on in the Start Time data entry boxes. Set a start time and an end time using the 24 hour clock notation. The times are inclusive.
Step 6 Set the End Date. You have two options when setting the end date. 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. Or, select the Now check box to view the data from the selected start date to the current time. By selecting this option, you do not need to update the End Date and Time fields.
Step 7 Set the End Time. You have two options when setting the end time. Enter the end date on which you wish to stop viewing performance data in the End Time entry boxes. The format must be mm/dd/yyyy. Or, select 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.
Step 8 From the drop-down list, choose the summary interval. The summary interval is the period of time over which the rule is applied. This varies according to the attribute selected. You can choose the Raw option, which displays performance data in its most detailed format, not summarized.
Note If you choose the Raw option, the bar chart view is not available, and the Summary Rule
option is dimmed.
Step 9 Click Refresh.
Refreshing the screen initiates your request for data. The text "Refresh Screen" is blue when you can refresh a screen and dimmed when this function is unavailable. Refresh Screen is available for selection when Now is selected or when any criteria have changed and you have moved the cursor away from the changed value (for example, by pressing the Tab key or by using the mouse).
A line chart of the performance information you requested appears on the right side of the Performance window. You can click any of the three tabs to display your data differently.
Note The performance information corresponds to the attribute raw values. If you select a
summary period, the information is displayed according to the summary rule. No summary
period is associated with raw data.
Performance Window Line Chart Tab
The Line Chart tab (see Figure 8-25) displays the retrieved data in a graphical format. The X-axis depicts the time at which the polling was done, and the Y-axis depicts the value retrieved or the value when the equipment did not respond properly.
Further information regarding the element, units, and missed polls is provided, using the appropriate color coding displayed at the top of the chart. Blue represents the values retrieved and red identifies any polled values missed.
Performance Window Bar Chart Tab
The information in this tab (see Figure 8-26) displays the retrieved data as a bar chart. Blue represents the values retrieved and red identifies any polled values missed.
Figure 8-26 Performance Window Bar Chart Tab
Performance Window Table Display Tab
This tab (see Figure 8-27) displays the data retrieved in a tabular format. The first column shows the time of polling, and the second column shows the retrieved values. Blue represents the values retrieved and red identifies any polled values missed.
Figure 8-27 Performance Window—Table Display Tab
Missed Polls
In some circumstances, possibly due to Cisco EMF being shut down or heavy network loads, an object might fail to be monitored. This is known as a missed poll. All missed polls are indicated by a yellow point on Performance Manager graphs and charts. The last valid value collected is shown. A missed poll affects the summary data and you should not rely upon such data.
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.
Note A polling events key appears for a selection.
Viewing ATM over ADSL over DMT Interface Performance Data
When you deploy a DMT line card, four ATM over ADSL over DMT interfaces are created automatically. For simplification, these interfaces are generally referred to as DMT interfaces throughout CDM. In a sense, the three technologies are combined in one interface. You can view performance information for any one of these technologies by selecting the one desired in the Performance Manager list box.
Step 1 In the Map Viewer window, within the Physical view, right-click the DMT interface whose performance you want to view.
Step 2 Choose Tools > Performance Manager from the object menu.
The Performance Manager window opens to the Line Chart tab. (See Figure 8-28.)
The Performance Manager window consists of three areas on the left, and three tabbed sections on the right. Choose the parameters you want from the areas on the left.
Step 3 From the Monitored Attributes list, choose the attribute you want to monitor.
This list includes attributes for ATM, ADSL, and DMT interfaces. You can choose multiple contiguous 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. Information for all selected attributes is shown in the table display. Only the first selected attribute is shown in the line chart or bar chart.
Step 4 In the Time Period area, choose the time parameters.
Step 5 Set the Start Date, as follows:
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.
Step 6 Set the End Date.
You have two options when setting the end date. 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. Or, select the Now check box to view the data from the selected start date to the current time. By selecting this option, you need not update the end date and time fields.
Step 7 Set the Start Time.
Enter the time when you want the performance data to start in the Start Time data entry boxes. Set a start time and an end time using the 24 hour clock notation. The times are inclusive.
Step 8 Set the End Time.
You have two options when setting the end time. Enter the end date on which you wish to stop viewing performance data in the End Time entry boxes. The format must be mm/dd/yyyy. Or, select 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.
Step 9 From the drop-down list, select the summary interval.
The summary interval is the period of time over which the rule is applied. This varies according to the attribute selected. You can choose the Raw option, which displays performance data in its most detailed format, not summarized.
Note If you choose the Raw option, the bar chart view is not available, and the Summary Rule
option is dimmed.
Step 10 Click Refresh.
Refreshing the screen initiates your request for data. The text "Refresh Screen" is blue when you can refresh a screen and dimmed when this function is unavailable. Refresh Screen is available for selection when Now is selected or when any criteria have changed and you have moved the cursor away from the changed value (for example, by pressing the Tab key or by using the mouse).
A line chart of the performance information you requested appears at the right. You can click in any of the three tabs to display your data differently.
Note The performance information corresponds to the attribute raw values. If you select a
summary period, the information is displayed according to the summary rule. No summary
period is associated with raw data.
The Performance window—Table Display tab displays retrieved data in a tabular format. (See Figure 8-29.)
