Recently I was troubleshooting a network where concerned Admin complained that they frequently lost connectivity with the Internet. Sometimes pings replies works okay but latency gets high or timeout / breaks occurs. So I decided to setup mrtg base ping graph to monitor ping latency. The custom made mrtg ping probe worked fine and can provide an overview on target ping / rtt and Downtime in a nice manner,
BUT . . . . . . . . . . . . . . . . . . .
I was thinking far ahead , I was thinking for much more advanced latency and pin point graphs which can show ping latency / rtt / loss in much more detailed way. I recalled my memory from old days when I used to monitor my old network with variety of tools and scripts and suddenly a name popped in my mind ” SMOKEPING ” , yes this was the tool I was looking for.
SmokePing generates graphs that can reveal the quality (packet loss and latency variability) & reach-ability of your IP address from several distributed locations. SmokePing is a network latency monitor. It measures network latency to a configurable set of destinations on the network, and displays its findings in easy-to-read Web pages. It uses RRDtool as its logging and graphing back-end, making the system very efficient. The presentation of the data on the Web is done through a CGI with some AJAX capabilities for interactive graph exploration.
- In this article I will show you howto install smokeping on UBUNTU 10/12
First install required components along with smokeping and apache2 (you can remove Apache or any other component if its not required or already installed)
aptitude install smokeping curl libauthen-radius-perl libnet-ldap-perl libnet-dns-perl libio-socket-ssl-perl libnet-telnet-perl libsocket6-perl libio-socket-inet6-perl apache2
Once all is installed, we have to modify few configuration files.
Open following following …
now remove sendmail entry by adding # sign to to comment the sendmail line, usually the first line.
Save and exit.
Now open following file
Now REMOVE all previous lines , and copy paste following
*** Targets *** probe = FPing menu = Top title = Network Latency Grapher remark = Welcome to the SmokePing website of <b>ZAIB (Pvt) Ltd.</b> Here you will learn all about the latency of our network.

save and exit.
now restart smokeping service by
service smokeping restart
and access it via browser.
Results should be something like below image…
