我正在寻找 node_sockstat_TCP_mem_* 指标的含义。节点导出器的输出对它们进行了如下描述:
# HELP node_sockstat_TCP_mem Number of TCP sockets in state mem.
# TYPE node_sockstat_TCP_mem gauge
node_sockstat_TCP_mem 6
# HELP node_sockstat_TCP_mem_bytes Number of TCP sockets in state mem_bytes.
# TYPE node_sockstat_TCP_mem_bytes
我知道套接字的状态类似于“ESTABLISHED”、“LISTEN”、“CLOSE_WAIT”...这个“mem”状态是什么?
