The chapter provides information on starting the IPM application and configuring a collector to gather response time data. It includes the following major sections:
To start the IPM server, database server, and client, enter the following commands:
# cd /opt/CSCOipm/bin # ./ipm
To start just the IPM server and database, enter the following commands:
# cd /opt/CSCOipm/bin # ./ipm start
To start just the IPM client on a Solaris workstation, enter the following commands:
# cd /opt/CSCOipm/bin # ./ipm start client
If you installed the IPM client on a different Solaris workstation from the IPM server, you must issue the ipm start command from the /opt/CSCOipmClient/bin directory. To start the IPM client on a different Solaris workstation from the IPM server, enter the following commands:
# cd /opt/CSCOipmClient/bin # ./ipm start client
To start the IPM client on a Windows NT workstation, follow these steps:
Step 1 Make sure the IPM server that you are connecting to is running on a UNIX workstation.
Step 2 Open the Cisco Internetwork Performance Monitor 2.0 program folder.
Step 3 Double click on the IPM client.
 | Tips You can also start the IPM client by double clicking on the IPM client icon on your desktop. |
When the IPM client starts, it displays the IPM Main window (Figure 2-1).
When you start IPM for the first time, the IPM Main window contains no collectors. As you configure collectors, they are displayed in this window. Each collector is a combination of a configured source, a target, and an operation. For each collector, you specify parameters for gathering statistics, generating event notifications, and scheduling.
To monitor response time data with IPM, you must complete the following tasks:
IPM source routers are the routers from which packets are sent to measure and store response-time data. Each source router must contain the Cisco IOS software RTR feature.
To define a new source router, follow these steps:
Step 1 Verify that the SNMP read community and write community strings are configured properly on the router and verify that the router is configured to send RTR-generated traps to your NMS host. For information on configuring SNMP on the source router, see the "Configuring Your Routers to Send RTR-Related Traps" section in "Preparing to Install" chapter of the Internetwork Performance Monitor User Guide.
Step 2 From the IPM Main window (Figure 2-1), select Configure > Source Router. The Source Router window (Figure 2-2) is displayed.
Step 3 From the Source Router window, select Edit > Add. The Add Source Router window (Figure 2-3) is displayed.
Step 4 In the Source Router field, enter the IP address or host name of the router on which the source resides. This host name can be from 1 to 64 characters.
Step 5 In the Read Community field, enter the community name (or password) for read access to the information maintained by the SNMP agent. This value can be from 1 to 32 characters. The default value is public.
Step 6 In the Write Community field, enter the community name (or password) for write access to the information maintained by the SNMP agent. This value can be from 1 to 32 characters.
Step 7 Click OK to configure this source. IPM attempts to locate the router and determine whether or not it is SNMP enabled with the correct community string. If the router is successfully located, IPM adds it to the Source Router window. If IPM cannot reach the router, IPM displays an error message and redisplays the Add Source Router window.
For information on using a seed file to add source routers to IPM, see the "Adding Source Routers Using a Seed File" section in the "Modifying IPM Components" chapter. For information on modifying or deleting source routers, see the "Working with Source Routers" section in the "Modifying IPM Components" chapter.
IPM targets are destination devices for which you want to gather response-time data. A target can be an SNA host or any IP-addressable device.
To define a device as a target, follow these steps:
Step 1 Select Configure > Target from the IPM Main window (Figure 2-1). The Target window (Figure 2-4) is displayed.
Step 2 From the Target window, select Edit > Add. The Add Target window (Figure 2-5) is displayed.
Step 3 In the Target Type field, select the protocol type to be used with this target. The possible values are:
Step 4 If the target type is IP, enter the IP address or host name of the target device in the IP Address or Host Name field. This is the name that appears in the Target field when you define a collector.
Step 5 For SNA Echo or SNA SSCP Echo, enter the SNA host name of the target device in the VTAM PU Name field. This is the name that appears in the Target field when you define a collector.
Step 6 For target type, SNA Echo, enter the eight-character SNA log mode name to be used to access the NSPECHO host application in the SNA Log Mode Name field. If you omit this value, default session parameters are used when communicating with the NSPECHO application running on the mainframe.
The SNA host uses this name to find the log mode table entry that defines session parameters. If you omit this name, the SNMP agent in the source router sends a name of all blanks to the SNA host, which then uses a set of default session parameters for the echo session.
Step 7 Click OK. IPM closes the Add Target window and the newly defined target is added to the list of defined targets in the Target window.
For information on using a seed file to add targets to IPM, see the "Adding Targets Using a Seed File" section in the "Modifying IPM Components" chapter. For information on modifying or deleting targets, see the "Working with Target Devices" section in the "Modifying IPM Components" chapter.
When you install IPM, a group of predefined operations are provided. Use one of these operations when you define a collector. You can also define one or more new operations to fit your needs. For information on defining a new operation, see the "Adding a New Operation" section in the "Modifying IPM Components" chapter.
The predefined operations are described in Table 2-1.
| Operation | Description |
|---|---|
default-ip-echo-monitored | Monitors end-to-end response time in an IP network without gathering statistics. |
default-ip-echo-statistics | Gathers statistics for end-to-end response time in an IP network. |
default-path-echo-monitored | Monitors hop-by-hop response time in an IP network without gathering statistics. |
default-path-echo-statistics | Gathers statistics for hop-by-hop response time in an IP network. |
default-sna-lu0-echo | Monitors end-to-end response time in an SNA network using LU0 without gathering statistics. |
default-sna-sscp-echo | Monitors end-to-end response time in an SNA network using SSCP protocol without gathering statistics. |
For information on defining, modifying, or deleting operations, see the "Working with Operations" section in the "Modifying IPM Components" chapter.
Defining a collector involves selecting a source router, a target, an operation, and a collector schedule.
To define a new collector, follow these steps:
Step 1 From the IPM Main window (Figure 2-1), select Edit > Add. The Add Collector window (Figure 2-6) is displayed.
Step 2 From the Source Routers list, select the router to designate as the source router for collecting data.
Step 3 From the Target Names list, select the device to designate as the target.
Step 4 From the Operation Names list, select the operation and type to use for this collector.
Step 5 To configure the schedule for the collector when you start it, enable the OnDemand option.
Step 6 To specify when the collector starts, choose one of the following options in the Start Time field:
Step 7 To specify how long the collector runs, choose one of the following options in the Duration field:
Step 8 Click OK. The collector that you defined is displayed in the list of collectors in the IPM Main window.
For information on using a seed file to add collectors to IPM, see the "Adding Collectors Using a Seed File" section in the "Modifying IPM Components" chapter. For information on viewing or deleting collectors, see the "Working with Collectors" section in the "Modifying IPM Components" chapter.
As your collectors begin to collect response time information and the information is stored in the IPM database, you are able to view the resulting statistical data. You view the response-time results from any of the collectors listed on the IPM Main window and see whether or not that collector is active or inactive.
IPM provides two methods for reviewing response-time data:
The Real Time Display window allows you to view response time data for an active collector as the data is being collected. This data is only displayed in real time, it is not stored in the IPM database.
To view response-time data in real time, follow these steps:
Step 1 From the IPM Main window (Figure 2-1), select the collector to be viewed.
Step 2 Select View > Display Real-time. The Real Time Display window (Figure 2-7) is displayed.
Response-time data is displayed as soon as the frequency interval elapses. Data points will be added to the graph for each interval that the response time is measured for the selected collector.
To view response time statistics, follow these steps:
Step 1 From the IPM Main window (Figure 2-1), select the collector to be viewed.
Step 2 Select View > Display Stats. The Time Filter window (Figure 2-8) is displayed.
In this window, you select the starting and ending time for the statistics that you want to view. These times relate to when the statistics are gathered by the collector, not when you want to view them. When this window is displayed, it already contains the starting and ending times for the collector, so you can press Enter to view statistics for that time period.
Step 3 In the Start Time field, specify the starting time for the response-time statistics you want to view. This marks the earliest statistics you want to view. For example, although your collector gathered statistics from 10:00 to 23:00, you may be interested in only those gathered from 11:00 to 13:00. In this case, you would indicate 11:00 as the start time.
You can specify the Start Time in one of these ways:
Step 4 In the End Time field, enter the ending time (the latest statistics) for the response-time statistics you want to view. For example, although your collector collected statistics from 10:00 to 23:00, you may be interested in only those gathered from 11:00 to 13:00. In this case, you would indicate 13:00 as the end time.
You can specify the end time in one of the following ways:
Step 5 In the Statistics Format field, specify the initial increment for the granularity to be used for displaying the response-time statistics graphs. Choose one of the available options: Hourly, Daily, Weekly, or Monthly.
Step 6 Click OK. The Response Graphs window (Figure 2-9) is displayed.
Step 7 Select one of the path icons to see all the hops for that path, and then select one of the hops. The response-time statistics for that hop are displayed in the Response Graphs window.
You can print the data for each of the graphs in the Response Graphs window.
To print the data of an a IPM graph, follow these steps:
Step 1 From the Response Graphs window (Figure 2-9), select File > Print.The Print Dialog window (Figure 2-10) is displayed.
Step 2 Enter data in the following fields:
Step 3 Click Print.
When you have finished configuring collectors or viewing response-time statistics, exit the IPM client by completing the following steps:
Step 1 From the IPM Main window (Figure 2-1), select File > Exit. A confirmation window (Figure 2-11) is displayed.
Step 2 Click Yes to close the IPM client application. Active collectors will continue to run and gather response time data.
