Identifying Network Connectivity Failure

If the IP addresses of the management server, monitoring agent or the data network are unavailable, an event indicates that there is a network connectivity problem. This is part of network reachability monitoring. See Network Reachability Monitoring for more information. The event log becomes available from the browser interface. The length of time it takes for the event log to be available from the browser interface depends on the polling interval for the attribute:

t + polling interval

The time at which the breach occurs is indicated by t. The polling interval is in seconds, and is the amount of time between successive polls of the monitored attribute. See Setting Polling Intervals for more information. Use the show log command to verify that the event log has been generated:
