Use DNS attributes to create situations to monitor DNS (Domain Name Server) server activity and performance.
DNS attributes are conveniently separated into five groups:
DNS Dynamic Update
DNS Memory
DNS Query
DNS WINS
Use DNS Dynamic Update attributes to create situations to monitor dynamic update activity (both successful and failed) generated by clients. Use DNS Memory attributes to create situations to monitor DNS server activity associated with memory usage for User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) traffic. Use DNS Query attributes to create situations to monitor various aspects of DNS server activity such as overall queries and responses processed by the server for User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) traffic. Use DNS WINS attributes to create situations to monitor WINS lookup requests and responses that were sent and received by the server. Use DNS Zone Transfer attributes to create situations to monitor the success of zone transfer requests and responses that are sent and received by the master and secondary DNS servers.
DNS Dynamic Update is a single-instance attribute group.
Dynamic Update NoOperation The total number of No-operation/Empty dynamic update requests received by the DNS server. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
Dynamic Update NoOperation/sec The average number of No-operation/Empty dynamic update requests received by the DNS server in each second. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
Dynamic Update Queued The total number of dynamic updates queued by the DNS server. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
Dynamic Update Received The total number of dynamic update requests received by the DNS server. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
Dynamic Update Received/sec The average number of dynamic update requests received by the DNS server in each second. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
Dynamic Update Rejected The total number of dynamic updates rejected by the DNS server. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
Dynamic Update TimeOuts The total number of dynamic update timeouts of the DNS server. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
Dynamic Update Written to Database The total number of dynamic updates written to the database by the DNS server. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
Dynamic Update Written to Database/sec The average number of dynamic updates written to the database by the DNS server in each second. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
Secure Update Failure The total number of secure updates failed of the DNS server. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
Secure Update Received The total number of secure update requests received by the DNS server. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
Secure Update Received/sec The average number of secure update requests received by the DNS server in each second. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
System Name The network name of the source of this information. Valid format is a text string of up to 64 characters.
Timestamp The date and time the Tivoli Enterprise Monitoring Server samples the data. Standard 16-character date/time format (CYYMMDDHHMMSSmmm), where:
C |
Century (0 for 20th, 1 for 21st) |
YY |
Year |
MM |
Month |
DD |
Day |
HH |
Hour |
MM |
Minute |
SS |
