How to use smokeping to monitor the network quality of the idc computer room? from the delay and packet loss on the monitoring chart, you can tell whether the network of your computer room is stable, whether it is multi-line, whether it is a BGP room, and what is the situation of each of the three operators' networks in each city. If there is a problem, if there is a solution. And if you choose a new computer room, you can judge whether it is suitable or not according to the monitoring results of smokeping.

Chart parameter description

(1) RTT (Round-Trip Time): to put it simply, it is the time in which a Datagram goes back and forth between two points on the network. It is an important parameter that affects the performance of TCP and characterizes the operation of the network. Real-time and accurate measurement of RTT parameters of a large number of TCP devices and systems in the network is one of the important links of network management. Smokeping is such an automated test system, which sends various types of test packets to target devices and systems, measures, records, and displays RTT.

(2) Median RTT: it is the median, not the average. Smokeping has many types of probes, which, by default, send 20 probe packets to the target device every 300 seconds. If all 20 packets are returned, it records 20 RTT, then MedianRTT is the RTT; of the tenth packet. If five packets are lost, then MedianRTT is the RTT value of the eighth returned packet.

(3) Avg RTT: it is the arithmetic evaluation value of all RTT in each test round.

(4) Avg pkt loss: packet loss rate.

(5) Probe:100ICMP Echo Pings (56 Bytes) every300s each green dash is tested 100 times with ping in 300 seconds. Green shows the position of the middle number, and the other values in a turn are depicted in grayscale near it.

Next, let's deploy smokeping. First, turn off selinux, the firewall and turn off systemctl stopfirewalld.service.

The time synchronization method is as follows:

Yum install rdate-y

Vi/etc/sysconfig/clock

ZONE= "Asia/Shanghai"

Ln-sf/usr/share/zoneinfo/Asia/Shanghai / etc/localtime

/ usr/bin/rdate-stime.nist.gov

1. Install the dependency package

Yum groupinstall "Compatibility libraries"Base"Developmenttools"-y # installs the required components to ensure environmental consistency

Yum install-y perlperl-Net-Telnet perl-Net-DNS perl-LDAP perl-libwww-perl perl-IO-Socket-SSLperl-Socket6 perl-Time-HiRes perl-ExtUtils-MakeMaker rrdtool rrdtool-perlcurl httpd httpd-devel gcc make wget libxml2-devel libpng-devel glib pangopango-devel freetype freetype-devel fontconfig cairo cairo-devel libart_lgpllibart_lgpl-devel perl-CGI-SpeedyCGI perl-Sys-Syslog popt-devel libidn-develfping

2. Install smokeping-2.6.8.tar.gz

Wget http://pkgs.fedoraproject.org/repo/pkgs/smokeping/smokeping-2.6.8.tar.gz/md5/14a968daab2d17a27d41600077e3e967/smokeping-2.6.8.tar.gz

Tar xvfsmokeping-2.6.8.tar.gz

Cd smokeping-2.6.8

. / setup/build-perl-modules.sh/usr/local/smokeping/thirdparty

. / configure--prefix=/usr/local/smokeping

/ usr/bin/gmake install

/ usr/bin/gmake install # important installation twice

3. Configuration modification

Cd/usr/local/smokeping/

Mkdir cache datavar

4. Apache configuration modification

Modify the master configuration file

Vim/etc/httpd/conf/httpd.conf

DocumentRoot "/ var/www/html" = = > > DocumentRoot "/ usr/local/smokeping"

= = > >

Add somekping configuration

Vim/etc/httpd/conf.d/somekping.conf

Alias / cache "/ usr/local/smokeping/cache/"

Alias / cropper "/ usr/local/smokeping/htdocs/cropper/"

Alias / smokeping "/ usr/local/smokeping/htdocs/smokeping.fcgi"

AllowOverride None

Options All

AddHandlercgi-script .fcgi .cgi

Orderallow,deny

Allow from all

DirectoryIndexsmokeping.fcgi

Systemctl restarthttpd

Visit and test.

Up to this point, the smokeping is not ready for use and needs to be configured.

At this time, if you start, there will be garbled code in Chinese, so solve it before starting.

Modification of character set

Vim/usr/local/smokeping/etc/config

* Presentation***

Charset = utf-8

# add charset = utf-8 under Presentation and then save and exit

Yum-y installwqy-zenhei-fonts # install font pack

Vim/usr/local/smokeping//lib/Smokeping/Graphs.pm

My $val = 0

For my $host (@ hosts) {

My ($graphret,$xs,$ys) = RRDs::graph

("dummy"

'--start', $tasks [0] [1]

'--end', $tasks [0] [2]

'--font TITLE:20 ", # add this line

"DEF:maxping=$cfg- > {General} {datadir} ${host} .rrd: median:AVERAGE"

'PRINT:maxping:MAX:%le')

My $ERROR = RRDs::error ()

Finally start smokeping

View the state of the network

Smokeping can easily view the state of the network being monitored:

(1) the delay and packet loss of the network can be seen in the figure.

(2) it has a Last 3 Hours,Last 30 Hours,Last 10 Days,Last 400 Days image, and you can view the image by entering a specific period of time, as follows:

(3) multi-graph draws the values of multiple monitoring points in one map to facilitate comparative analysis and overall condition statistics, as shown below:

(4) you can check "Top Packet Loss", "Top Max RoundtripTime", "Top Median RoundtripTime" and "Top Standard Deviation" under "Charts", so that you can easily judge where there is something wrong with the network, so that you can deal with it quickly. As shown in the following figure:
