The IP Availability Manager and the IP Performance Manager monitor the health of the IP network by periodically sending ICMP polls and SNMP polls to the discovered network devices. The results of the polling are compared to threshold values that define acceptable and unacceptable levels of connectivity or performance.
The polled data and the thresholds, in conjunction with received traps, are used by the IP Availability Manager and the IP Performance Manager to detect the failed or degraded objects that adversely affect network performance. In addition, the polled data, thresholds, and received traps are used by the IP Availability Manager and the IP Performance Manager to collect or determine status updates, which are imported by the IP Manager to diagnose the failed or degraded objects that interrupt network connectivity.
IP Manager User Guide provides a description of ICMP and SNMP polling for correlation analysis.
The IP Manager Reference Guide describe the events that are diagnosed by the IP Availability Manager and the IP Performance Manager.
