Alert name tcp_orphans	On metricipv4.sockstat_tcp_sockets	Descriptionorphan IPv4 TCP sockets utilization
Alert name tcp_memory	On metricipv4.sockstat_tcp_mem	DescriptionTCP memory utilization

Metrics

Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per Socket statistics instance

This scope has no labels.

Metrics:
