![普罗米修斯节点导出器 sockstat](https://linux22.com/image/220660/%E6%99%AE%E7%BD%97%E7%B1%B3%E4%BF%AE%E6%96%AF%E8%8A%82%E7%82%B9%E5%AF%BC%E5%87%BA%E5%99%A8%20sockstat.png)
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?
