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 Query is a single-instance attribute group.

Recursive Send TimeOuts The total number of recursive query sending timeouts. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
Recursive TimeOut/sec The average number of recursive query sending timeouts 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.
TCP Query Received The total number of TCP queries received by 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.
TCP Query Received/sec The average number of TCP queries received by 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.
TCP Response Sent The total number of TCP responses sent by 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.
TCP Response Sent/sec The average number of TCP responses sent by 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.
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 |
Second |
mmm |
Millisecond |
Use simple text strings as described above. For example, enter 0971009130500000 to express October 9, 1997, 1:05:00 pm.
