Use TCP Statistics attributes to monitor connection statistics and segment traffic for data using the TCP protocol. TCP Statistics is a single-instance attribute group. This attribute group reports IPv4 statistics. IPv6 statistics are reported separately on Windows 2003.
Connections Active The number of times TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. Note: the value 2147483647 indicates Value_Exceeds_Maximum and the value -2147483648 indicates Value_Exceeds_Minimum.
Connections Established The number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. Note: the value 2147483647 indicates Value_Exceeds_Maximum and the value -2147483648 indicates Value_Exceeds_Minimum.
Connection Failures The number of times TCP connections have made a direct transition to the CLOSED state from the SYN-SENT state or from the SYN-RCVD state. This number also includes the number of times TCP connections have made a direct transition to the LISTEN state from the SYN-RCVC state. Valid format is a text string of up to 64 characters. Note: the value 2147483647 indicates Value_Exceeds_Maximum and the value -2147483648 indicates Value_Exceeds_Minimum.
Connections Passive The number of times TCP connections have made a direct transition to the SYN-RCVD state from the LISTEN state. Valid format is a text string of up to 64 characters. Note: the value 2147483647 indicates Value_Exceeds_Maximum and the value -2147483648 indicates Value_Exceeds_Minimum.
Connections Reset The number of times TCP connections have made a direct transition to the CLOSED state from either the ESTABLISHED state or the CLOSE-WAIT state. Valid format is a text string of up to 64 characters. Note: the value 2147483647 indicates Value_Exceeds_Maximum and the value -2147483648 indicates Value_Exceeds_Minimum.
Segments Received/sec The rate that segments are received, including those received in error. This count includes segments received on currently established connections. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. Note: the value 2147483647 indicates Value_Exceeds_Maximum and the value -2147483648 indicates Value_Exceeds_Minimum.
Segments Retransmitted/sec The rate that segments are retransmitted, that is, segments transmitted containing one or more previously transmitted bytes. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. Note: the value 2147483647 indicates Value_Exceeds_Maximum and the value -2147483648 indicates Value_Exceeds_Minimum.
Segments/sec The rate that TCP segments are sent or received using the TCP protocol. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
Segments Sent/sec The rate that segments are sent, including those on current connections. This count excludes those containing only retransmitted bytes. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. Note: the value 2147483647 indicates Value_Exceeds_Maximum and the value -2147483648 indicates Value_Exceeds_Minimum.
System Name The managed system name. The form should be hostname:agent_code.
Examples include spark:KNT or deux.raleigh.ibm.com:KNT.
In workspace queries, this attribute should be set equal to the value $NODE$ in order to populate the workspace with data. This attribute is generally not included in situations, unless there is a need to customize the situation for a specific managed system.
Timestamp The date and time the Tivoli Enterprise Monitoring Server samples the data.
