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 Memory is a single-instance attribute group.
Caching Memory The total caching memory used 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.
Database Node Memory The total database node memory used 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.
Nbstat Memory The total Nbstat memory used 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.
Record Flow Memory The total record flow memory used 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.
System Name The network name of the source of this information. Valid format is a text string of up to 64 characters.
TCP Message Memory The total TCP message memory used 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.
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.
UDP Message Memory The total UDP message memory used 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.
