Linux网络统计工具命令

xiaoxiao2024-01-07 152

我在Linux(基于CentOS 或者 Debian 的发行版)中该如何查看当前网络端口吞吐量的统计信息？在Linux操作系统中如何查看当前内核snmp计数器以及网络端口的统计信息？

你可以使用以下任何一个命令：

nstat 命令 : 网络统计工具

键入以下命令:

# nstat

输出样例:

#kernelIpInReceives 133243 0.0IpInDelivers 133243 0.0IpOutRequests 92904 0.0IcmpOutErrors 97 0.0IcmpOutTimeExcds 97 0.0IcmpMsgOutType3 97 0.0TcpActiveOpens 538 0.0TcpEstabResets 56 0.0TcpInSegs 129837 0.0TcpOutSegs 89720 0.0TcpRetransSegs 42 0.0TcpOutRsts 704 0.0UdpInDatagrams 3255 0.0UdpNoPorts 97 0.0UdpOutDatagrams 3270 0.0Ip6OutNoRoutes 206 0.0TcpExtTW 141 0.0TcpExtDelayedACKs 508 0.0TcpExtDelayedACKLocked 1 0.0TcpExtDelayedACKLost 42 0.0TcpExtTCPHPHits 117659 0.0TcpExtTCPPureAcks 2158 0.0TcpExtTCPHPAcks 605 0.0TcpExtTCPSackRecovery 1 0.0TcpExtTCPLossUndo 16 0.0TcpExtTCPSackFailures 4 0.0TcpExtTCPFastRetrans 1 0.0TcpExtTCPSlowStartRetrans 3 0.0TcpExtTCPTimeouts 33 0.0TcpExtTCPDSACKOldSent 40 0.0TcpExtTCPDSACKRecv 5 0.0TcpExtTCPAbortOnData 120 0.0TcpExtTCPAbortOnClose 55 0.0TcpExtTCPSackShiftFallback 9 0.0IpExtInOctets 180131682 0.0IpExtOutOctets 7289106 0.0

ss 命令 : 查询套接字工具

要查看统计汇总, 输入:

# ss -s

输出样例:

Total: 786 (kernel 804)TCP: 65 (estab 40, closed 7, orphaned 0, synrecv 0, timewait 6/0), ports 56Transport Total IP IPv6* 804 - -RAW 1 1 0UDP 12 9 3TCP 58 52 6INET 71 62 9FRAG 0 0 0

netstat 命令 : 不错的显示套接字信息的旧工具

查看所有网络端口以及汇总信息表，输入：

# netstat -i

输出样例:

Kernel Interface tableIface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flgeth0 1500 0 941022 0 0 0 688165 0 0 0 BMRUlo 16436 0 9304 0 0 0 9304 0 0 0 LRUppp0 1496 0 3784 0 0 0 4177 0 0 0 MOPRU

查看每个协议的汇总统计信息，输入：

# netstat -s

输出样例:

ip / ifconfig 命令 : 配置或者显示网络端口信息

键入以下命令:

# ifconfig

或者

# /sbin/ifconfig

或者

# ifconfig eth0
