Understanding polling groups and settings
monitors the network by sending Simple Network Management Protocol (SNMP) polls and by processing SNMP
traps, by sending Simple Object Access Protocol (SOAP) requests and by processing the responses, and by processing information from the . The results of the polling and trap
processing are then compared to threshold values that define acceptable and unacceptable levels of availability. The polling and trap processing results, in conjunction with the status updates received from
IP Availability Manager
, are used to diagnose the failed objects that interrupt network service connectivity. uses settings to assign
polling and threshold parameters to groups of managed objects. From a polling and threshold perspective, a setting is a collection of parameters common to a particular type of analysis (for example, network services polling).
Using the Polling and Thresholds Console, you can customize SNMP polling and SOAP querying
for by modifying default polling groups or by creating
new polling groups. The polling groups periodically poll or query the managed devices to
collect availability data for application services, network services, and other
VoIP-related objects. The data serves as input to the correlation analysis function of
.
Appendix B, Polling for Analysis, describes SNMP and SOAP polling for correlation
analysis.
