Currently tcpconn.py uses netstat to get it's socket stats. This gives lots of detail but is far too slow for much production use (running netstat can take many minutes). /proc/net/sockstat gives less information but has no performance problems. There was a suggestion previously to use the ss command, but (1) it's less common (at least not part of the default on RHEL5) and (2) it also lacks the high fidelity details.
Is there any other reason to prefer ss over cat? Should this replace tcpconn, or be a new module? Example output: $ cat /proc/net/sockstat sockets: used 292 TCP: inuse 1103 orphan 974 tw 701725 alloc 1104 mem 1096 UDP: inuse 6 mem 1 UDPLITE: inuse 0 RAW: inuse 0 FRAG: inuse 0 memory 0 ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
