TCP Version 6 Overview (PI_TCP6)

Function

The TCP Version 6 Overview (PI_TCP6) record stores the performance data per unit time on the number of times TCP segments were sent/received when the TCP protocol of Internet Protocol Version 6 was used, and the number of TCP connections.

Default values and values that can be specified

ItemDefault valueModifiable
Collection Interval60Yes
Collection Offset#0Yes
LogNoYes
LOGIFBlankYes
#
A value between 0 and 32,767 seconds can be specified (a value within the range specified for Collection Interval). Use this item to distribute the collection load, because executing data collection all at once results in concentration of the processing workload. Note that the data collection duration to be recorded is the same as the Collection Interval, regardless of the value specified for Collection Offset.
