BUT . . . . . . . . . . . . . . . . . . .
I was thinking far ahead , I was thinking for much more advanced latency and quality 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) & reachability 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 FEDORA 10.
HOWTO INSTALL SMOKEPING on FEDORA 10
Installing Smokeping is relatively simple. Just issue this command as root.
1
| yum -y install smokeping |
NOTE: selinux is the Problem. By default its enabled in Fedora installation. Disable it by editing
1
| nano /etc/selinux/config |
1
| SELINUX=disable |
After installation completes, You can access it via
You will see something similar as shown in the following screenshot.
NOTE: If you get “Access Denied: You don’t have permission to access this Folder” error, edit the following line.
1
| nano /etc/httpd/conf.d/smokeping.conf |

1
| service httpd restart |
Now It’s time to add your target in Smokeping for monitoring. The default location for the Smokeping config file is /etc/smokeping/config, Now just for example, we will edit this file.
1
| nano /etc/smokeping/config |

Now click on LAN connectivity to open graphs. You will see something similar as shown in the following screenshot.
Now, Click on WAN Connectivity
Now click on the Yahoo Ping Graph showing on Right to get more detailed graph report.
To get more detailed view, click on Last 3 hours graphs, It will open this graph in NAVIGATOR mode. Now here you can select any specific area to zoom to troubleshoot at exact which time the latency problems occurs. For example in the following screenshot you can see the blue dots which shows that ping timeout occurs at specific time.
PULL DATA FROM SPECIFIC TIME
A client complained that the internet worked very slow in the morning at 10:30am. So you can pull data from smokeping graph to validate the complain or to troubleshoot what exactly happened at 10:30am :)
As you can see the blue dots showed that the ping breaks occured in the specific timings.
There are so many interesting things you can do with SMOKE-PING.
