Read sockstat info from /proc/net/sockstat and /proc/net/sockstat6

example file

sockets: used 211
TCP: inuse 9 orphan 0 tw 19 alloc 47 mem 22
UDP: inuse 2 mem 0
UDPLITE: inuse 0
RAW: inuse 0
FRAG: inuse 0 memory 0

The content of "/proc/net/sockstat" in a Linux system provides information about the socket usage on the system. The fields and their meaning are as follows:

sockets: used: Total number of used sockets on the system. TCP: inuse: Number of currently established TCP sockets. orphan: Number of orphaned TCP sockets. tw: Number of sockets in TIME_WAIT state. alloc: Number of sockets allocated. mem: Memory used by TCP sockets. UDP: inuse: Number of currently established UDP sockets. mem: Memory used by UDP sockets. UDPLITE: inuse: Number of currently established UDP-Lite sockets. RAW: inuse: Number of currently established raw sockets. FRAG: inuse: Number of currently established fragment sockets. memory: Memory used by fragment sockets. These fields provide a snapshot of the socket usage on the system, including the number of sockets in use and memory usage, which can be useful for monitoring and troubleshooting network issues.
