Network assurance checks network connectivity to each server that
you configure, such as the NTP server, RADIUS servers, SNMP trap
hosts, etc. By proactively identifying network resources that are
unavailable, the network manager can be alerted of problems
potentially before end-users notice an issue. The distributed
intelligence of Arrays provides this monitoring at multiple points
across the network, adding to the ability to isolate the problem and
expedite the resolution
Connectivity is checked when you configure a server. If a newly
configured server is unreachable, you will be notified directly and a
Syslog entry is created. Configured servers are checked once per
Period which by default is 300 seconds (five minutes). Servers are
checked regardless of whether they are configured as IP addresses or
host names.
If a server becomes unreachable, a Syslog message is generated.
When the server again becomes reachable, another Syslog message is
generated.
To view the status of all configured servers checked by this feature,
please see “Network Assurance” on page 109.
