Generating Performance and Inventory Reports with Cisco Cable Manager

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.

Generating Performance Reports

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.

Generating MAC Throughput Reports

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 Identifier—The containment path in the Object Tree.

¯ In Utilization—Utilization calculated with inbound ifTable counters.

¯ The formula is (delta_ifOutOctets * 8 * 100) / (ifSpeed * delta_time).

¯ In Discard Rate—Number 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 Rate—This error rate is calculated with inbound ifTable counters. The formula is (delta_ifOutErrors * 100 / delta_outTotal).

¯ Out Utilization—This utilization is calculated with outbound ifTable counters. The formula is (delta_ifOutOctets * 8 * 100) / (ifSpeed * delta_time).

¯ Out Discard Rate—Number 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 Rate—This 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.

Generating Cable Modem Summary and Detailed Inventory Reports

Cable Modem Summary Report

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:

The following service types are used to distinguish modems:

This report also calculates the following percentages:

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.

Cable Modem Detailed Inventory Report

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.
