Operating system-dependent variables and pathsThis publication uses environment variables without platform-specific prefixes andsuffixes, unless the command applies only to specific platforms. For example, thedirectory where the Network Manager core components are installed is representedas NCHOME.When using the Windows command line, preface and suffix environment variableswith the percentage sign %, and replace each forward slash (/) with a backslash (\)in directory paths. For example, on Windows systems, NCHOME is %NCHOME%.On UNIX systems, preface environment variables with the dollar sign . Forexample, on UNIX, NCHOME is NCHOME.The names of environment variables are not always the same in the Windows andUNIX environments. For example, %TEMP% in Windows environments isequivalent to TMPDIR in UNIX environments. If you are using the bash shell ona Windows system, you can use the UNIX conventions.xiiIBM Tivoli Network Manager IP Edition: Event Management Guide

Chapter 1. About polling the networkTo poll the network, Network Manager periodically sends queries to the devices onthe network. These queries determine the behavior of the devices, for exampleoperational status, or the data in the Management Information Base (MIB)variables of the devices.Network polling is controlled by poll policies. Poll policies consist of the following:v Poll definitions, which define the data to retrieve.v Poll scope, consisting of the devices to poll. The scope can also be modified at apoll definition level to filter based on device class and interface.v Polling interval and other poll properties.Network Manager uses the IBM Tivoli Netcool/OMNIbus SNMP trap probe andthe Syslog probe to monitor the network. To run Tivoli Netcool/OMNIbus probes,use Tivoli Netcool/OMNIbus process control.For more information about how to use Tivoli Netcool/OMNIbus process control,see the IBM Tivoli Netcool/OMNIbus Administration Guide.The polling process is controlled by the ncp poller process. The ncp poller processstores SNMP information in the ncmonitor database; other data is storedin-memory.Network Manager has a multiple poller mechanism to distribute the load. If thedefault poller cannot handle the polling demands for your network, you mightneed to use the multiple poller feature.Related tasks:“Administering multiple pollers” on page 62If multiple pollers are needed to poll your network, you can set up NetworkManager to administer the multiple poller feature. You can add pollers or removepollers, or use a poller ID to associate a specific poller with a policy.Related reference:“SNMP tables for polling in the ncmonitor database” on page 193The SNMP tables in the ncmonitor database are used by the polling engine,ncp poller, to store information on how to access each discovered device usingSNMP.Poll policiesPoll policies contain all the properties of a network poll operation. They specifyhow often a device is polled, the type of polling mechanisms employed to do thepolling, and the devices to be polled.Related reference:Appendix A, “Default poll policies,” on page 153Network Manager IP Edition provides a set of default poll policies. Use thisinformation to familiarize yourself with these policies. Copyright IBM Corp. 2006, 20131

Poll policy parametersUse this information to understand the parameters of a poll policy.Use the poll policy to define the following parameters:v Name of the poll policyv Enablement or disablement: A poll policy must be enabled for polling to takeplace.v Poll definitions: A poll policy can have one or more poll definitions associatedwith it. If interface-level filtering is required, the poll definition must containcertain settings. For each poll definition associated with the policy, you canspecify whether to store polled data for historical reporting. If this parameter isset, the data is stored in the ncpolldata database schema.Restriction: Storage of polled data is not supported for the Cisco Remote Ping,the Juniper Remote Ping, and the Generic Threshold poll definitions.v Polling intervalv Poller to which to assign the poll policy, if the multiple poller feature is set up.v Scope. This contains:– Network views: Specify the network views containing the devices that youwish to poll.– Device filters: Refine the list of devices that you want to be polled by filteringagainst the values of fields in the mainNo

Network Manager IP Edition provides a number of default poll definitions that fulfil the most common polling requirements. Poll definition parameters Use this information to understand the parameters of a poll definition. Network Manager provides default poll policies and definitions. Use the poll definition to define the following parameters:
