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> <br> Here you will learn all about the latency of our network.<br><br><br><br><br> This page is maintained by ZAIB.

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