EZZ9313I

Explanation
 This is a multi-line message that is issued by
the resolver to report statistical information about an unresponsive
name server. The statistics are based on data that was accumulated
by the resolver during the most recent monitoring interval. The data
is specific to the specified name server.
 In the message text:
 ipaddress
The IPv4 or IPv6 network address of the name server that is considered
to be unresponsive.
total_sent
The number of queries that were directed to the unresponsive name
server during the most recent monitoring interval. This value includes
domain name server (DNS) queries that were generated by an application
and resolver polling queries (total_polls_sent).
total_fail
The number of queries that were directed to the name server during
the most recent monitoring interval for which a response was not received.
This value includes failures to respond to DNS queries that were generated
by an application and to resolver polling queries (total_polls_fail).
total_polls_sent
The number of resolver polling DNS queries that were directed
to the unresponsive name server during the most recent monitoring
 interval.
total_polls_fail
The number of times that the name server did not respond to resolver
polling DNS queries that were directed to that name server during
 the most recent monitoring interval.
percent
The percentage of total DNS queries (total_sent)
to which the name  server did not respond during the most recent monitoring
interval.
