On my CentOS 8 (release 8.5.2111), "netstat -s" does not show TCPBacklogDrop and ListenOverflows, but they exist in "/proc/net/netstat".
Code: Select all
[root@node ~]# netstat -s | egrep -i '(queue|drop|overflow)'
2 outgoing packets dropped
2 dropped because of missing route
1521 packets pruned from receive queue because of socket buffer overrun
9446 ICMP packets dropped because they were out-of-window
629 packets collapsed in receive queue due to low socket buffer
TCPOFOQueue: 19253045
