1 服务器资源监控工具——Netperf

1.1 编译安装——Netperf

1. 源码编译安装

​ 下载源码：

wget https://github.com/HewlettPackard/netperf/archive/netperf-2.7.0.tar.gz

​ 解压进入目录：

tar -zxvf netperf-2.7.0.tar.gz
cd netperf-netperf-2.7.0/

​ 修改配置文件：

vi config.sub

#查找“x86”内容的位置，在其位置后面增加“aarch64”类型。在“case $basic_machine in”区域的两个位置修改。
1）
| x86 | xscale | xscalee[bl] | xstormy16 | xtensa \
修改为：
| x86 | aarch64 | xscale | xscalee[bl] | xstormy16 | xtensa \

2）
| x86-* | x86_64-* | xps100-* | xscale-* | xstormy16-* \
修改为：
| x86-* | aarch64-* | x86_64-* | xps100-* | xscale-* | xstormy16-* \

​ 生成Makefile：

./configure --host=aarch64 --build=aarch64

​ 编译安装：

make && make install

1.2 验证与运行——Netperf

1. 执行如下命令，查看Netperf版本

netperf -V

​ 返回内容如下所示，表示安装已经完成：

[root@controller netperf-netperf-2.7.0]# netperf -V
Netperf version 2.7.0

2. 运行

​ 在服务端运行指令：

netserver

​ 回显结果如下：

[root@controller netperf-netperf-2.7.0]# netserver
Starting netserver with host 'IN(6)ADDR_ANY' port '12865' and family AF_UNSPEC

​ 在客户端运行指令：

netperf-H host -l testlen -t testname

​ 其中参数说明如下：

-H host ：指定远端运行netserver的server IP地址。
-l testlen：指定测试的时间长度（秒）
-t testname：指定进行的测试类型，包括TCP_STREAM，UDP_STREAM，TCP_RR，TCP_CRR，UDP_RR

​ 运行客户端指令示例：

netperf -H xxx.xxx.xxx.xxx -l 60

​ 回显结果如下：

[root@controller netperf-netperf-2.7.0]# netperf -H xxx.xxx.xxx.xxx -l 60
MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to xxx.xxx.xxx.xxx () port 0 AF_INET
Recv   Send    Send
Socket Socket  Message  Elapsed
Size   Size    Size     Time     Throughput
bytes  bytes   bytes    secs.    10^6bits/sec

131072  16384  16384    60.00    40516.99

​ 结果内容说明如下：

1)远端系统（即server）使用大小为131072字节的socket接收缓冲；
2)本地系统（即client）使用大小为16384字节的socket发送缓冲；
3)向远端系统发送的测试分组大小为16384字节；
4)测试经历的时间为60秒。
5)吞吐量的测试结果为40516.99*10^6bits/秒。

​ 在缺省情况下，netperf向发送的测试分组大小设置为本地系统所使用的socket发送缓冲大小。

3. 详细参数

Usage: netperf [global options] -- [test options]

Global options:
    -a send,recv      Set the local send,recv buffer alignment
    -A send,recv      Set the remote send,recv buffer alignment
    -B brandstr       Specify a string to be emitted with brief output
    -c [cpu_rate]     Report local CPU usage
    -C [cpu_rate]     Report remote CPU usage
    -d                Increase debugging output
    -D time,[units] * Display interim results at least every time interval
                      using units as the initial guess for units per second
                      A negative value for time will make heavy use of the
                      system's timestamping functionality
    -f G|M|K|g|m|k    Set the output units
    -F lfill[,rfill]* Pre-fill buffers with data from specified file
    -h                Display this text
    -H name|ip,fam *  Specify the target machine and/or local ip and family
    -i max,min        Specify the max and min number of iterations (15,1)
    -I lvl[,intvl]    Specify confidence level (95 or 99) (99)
                      and confidence interval in percentage (10)
    -j                Keep additional timing statistics
    -l testlen        Specify test duration (>0 secs) (<0 bytes|trans)
    -L name|ip,fam *  Specify the local ip|name and address family
    -o send,recv      Set the local send,recv buffer offsets
    -O send,recv      Set the remote send,recv buffer offset
    -n numcpu         Set the number of processors for CPU util
    -N                Establish no control connection, do 'send' side only
    -p port,lport*    Specify netserver port number and/or local port
    -P 0|1            Don't/Do display test headers
    -r                Allow confidence to be hit on result only
    -s seconds        Wait seconds between test setup and test start
    -S                Set SO_KEEPALIVE on the data connection
    -t testname       Specify test to perform
    -T lcpu,rcpu      Request netperf/netserver be bound to local/remote cpu
    -v verbosity      Specify the verbosity level
    -W send,recv      Set the number of send,recv buffers
    -v level          Set the verbosity level (default 1, min 0)
    -V                Display the netperf version and exit
    -y local,remote   Set the socket priority
    -Y local,remote   Set the IP_TOS. Use hexadecimal.
    -Z passphrase     Set and pass to netserver a passphrase

For those options taking two parms, at least one must be specified;
specifying one value without a comma will set both parms to that
value, specifying a value with a leading comma will set just the second
parm, a value with a trailing comma will set just the first. To set
each parm to unique values, specify both and separate them with a
comma.

* For these options taking two parms, specifying one value with no comma
will only set the first parms and will leave the second at the default
value. To set the second value it must be preceded with a comma or be a
comma-separated pair. This is to retain previous netperf behaviour.
