This object indicates the resource for which the in-use gauge crosses a threshold the last time the system generated a ciapEventThresholdRising or ciapEventThresholdFalling notification. More specifically, this object indicates a row pointer corresponding to the resource, which may be one a row in one of the following tables: - ciapPoolGroupTable to indicate the in-use gauge associated with an IP address pool group has crossed a threshold. - ciapPoolTable to indicate the in-use gauge associated with an IP address pool has crossed a threshold. - ciapRangeTable to indicate the in-use gauge associated with a range of IP addresses has crossed a threshold. - ciapNetworkTable to indicate the in-use gauge associated with a set of IP networks (which includes IPv4 subnets and IPv6 prefixes) has crossed a threshold.
