This chapter describes procedures for generating predefined performance and inventory reports and contains the following sections:
You can generate customized performance reports using the Cisco EMF application called Performance Manager. For details, see your Cisco EMF documentation.
When you generate a Performance Report, you will be asked to enter the time and date range for the report.
Note Before you generate reports, turn on performance polling for the polling groups. Limit the start time and end time range because reports can take a long time to generate. |
See the "Using Performance Polling" section.
The CCM reporting applications communicate with Cisco EMF by using the Corba gateway.
To successfully generate performance reports, see "Troubleshooting Tips for Performance Reports" section.
This report is launchable from the Tools menu associated with either an UBR or a RF-card object, and will report the MAC throughput information for all MAC layers in the selected object's hierarchy.
Note Before you generate the report, polling must be turned on for CblUbrPolling.cblRFCardIfTbl polling group. See "Using Performance Polling" section. |
The features provided include:
for each timestamp when polling is performed successfully:
¯ Mac Layer IdentifierThe containment path in the Object Tree.
¯ In UtilizationUtilization calculated with inbound ifTable counters.
¯ The formula is (delta_ifOutOctets * 8 * 100) / (ifSpeed * delta_time).
¯ In Discard RateNumber of inbound packets that were discarded, even though no errors were detected to prevent their delivery. Packets may have been discarded to free up buffer space. This discard rate is calculated with inbound ifTable counters. The formula is (delta_ifOutDiscards * 100 / delta_outTotal).
¯ In Error RateThis error rate is calculated with inbound ifTable counters. The formula is (delta_ifOutErrors * 100 / delta_outTotal).
¯ Out UtilizationThis utilization is calculated with outbound ifTable counters. The formula is (delta_ifOutOctets * 8 * 100) / (ifSpeed * delta_time).
¯ Out Discard RateNumber of outbound packets that were discarded, even though no errors were detected to prevent their being transmitted. One possible reason for discarding such a packet could be to free up buffer space. Discontinuities in the value of this counter can occur at reinitialization of Cisco Cable Manager and at other system interruptions. This discard rate is calculated with outbound ifTable counters. The formula is delta_ifOutDiscards * 100 / delta_outTotal.
¯ Out Error RateThis error rate is calculated with outbound ifTable counters. The formula is (delta_ifOutErrors * 100 / delta_outTotal).
Note All the above delta values are computed for the counters between current and last timestamps. Delta time is computed between the current and last timestamps. delta_outTotal is the sum of delta_ifOutUcastPkts, delta_ifOutMulticastPkts, delta_ifOutBroadcastPkts, delta_ifOutDiscards and delta_ifOutErrors. MAC layer ifSpeed is not directly available from the agent. It is aggregated from all the upstream ifSpeed. |

By using CCM, you can generate the following inventory reports to manage the currently deployed Cisco uBR7200 series universal broadband routers:
The CCM reporting applications communicate with Cisco EMF by using the Corba gateway.
To successfully generate inventory reports, review the "Troubleshooting Tips for Inventory Reports" section.
When you generate uBR Inventory Reports, the following parameters appear on a per uBR basis:
Note The report can be saved, loaded, and printed, but a previously saved report cannot be saved again. |
The Map Viewer dialog box appears.
Step 2 Double-click the Physical containment level and expand the object tree.
Step 3 Select a site.
Step 4 From the right-click menu, choose Tools > uBR Inventory Report.
The uBR Inventory Report appears.
Step 5 You can also generate the uBR Inventory Report by selecting Regenerate Report from the Task menu.
The Cable Modem Summary Report is provided at the uBR level only.
This report analyzes the cable modem information retrieved from the uBR (via Cisco EMF) as well as LDAP, determines the category that the modem belongs to, and classifies, counts and displays the number of modems in each category based on the modem's service type. A total count of the modems in each category is also provided.
The modems are categorized as follows:
Note If LDAP is not configured or not accessible, only the registered modem category appears in the summary report. Without the LDAP database access, the provisioned modem list is not available, and modems cannot be categorized as non-provisioned or non-registered. |
The following service types are used to distinguish modems:
Note If a registered modem is not provisioned in LDAP, the reporting software cannot determine the service type of the modem. An ITCM which is not provisioned will be counted as a "Data and Voice ITCM." If the reporting software cannot resolve the service type of the modem, the modem will be counted as an "Unknown Service Type Modem." |
This report also calculates the following percentages:
Note If LDAP is not configured or not accessible, the above percentages cannot be computed, and therefore will not appear in the summary report. |
Users can click on any of the count columns in the summary report to display the detailed cable modem list belonging to that category. Users can retrieve archived reports also by clicking on a particular column.
Note The report can be saved, and loaded. But a previously saved report cannot be saved again. When a summary report is saved, its associated detailed reports are also saved. When the user loads a previously saved summary report, its associated detailed reports are also loaded. |
Note New detailed and summary reports will be generated when the user reselects the Summary Report menu. |
The Cable Modem Detailed Inventory Report is provided at the uBR, card, port, and cell levels.
This report analyzes the cable modem information retrieved from the uBR (via Cisco EMF) as well as LDAP, determines the category that the modem belongs to, and displays the detailed list of modems in each category.
The modems are categorized as follows to generate four sub-reports:
When the report is launched, the Registered Cable Modem List is displayed first. The user can view the other sub-reports by selecting the appropriate cable modem category.
Note If LDAP is not configured or not accessible, only the registered modem category appears in the summary report. Without the LDAP database access, the provisioned modem list is not available, and modems cannot be categorized as non-provisioned or non-registered. |
For each of the four sub-reports, a list of cable modems belonging to that category is displayed, with the MAC address and associated LDAP account number for each modem
Note If LDAP is not configured or not accessible, the modem account number information cannot be retrieved; therefore, the modem account number is displayed as N/A for registered modems. The modem account number is always displayed as N/A for non-provisioned modems. |
Note The Cable Modem Detailed Report can be saved and loaded, but a previously saved report cannot be saved again. |
The Map Viewer dialog box appears.
Step 2 Double-click the Physical containment level and expand the object tree.
