Smokeping is an amazing tool for monitoring a network.
Installing it on raspberry Pi is just 1 line command (however update your system first !!!):
sudo apt-get install smokeping sendmail
It will install a smokeping and sendmail. Of course this is my personal requirement and choice but I had to edit only file:
sudo nano /etc/smokeping/config.d/Targets
as I decided (for now) to block sending email alerts. Careful – if you do not block sending emails in Targets file, smokeping will keep crashing if sendmail is not configured! I blocked sendmail by actually adding # before #alerts = someloss – see config file sample below
Also to get everything working correctly I had to restart system and wait few minutes.
If you expirience any problem, it is worth to watch systemlogs:
tail -f /var/log/syslog
The first few lines of my Targets file looks like this:
*** Targets ***
probe = FPing
menu = Top
title = Network Latency Grapher
remark = Welcome to the SmokePing website of xxx Company. \
Here you will learn all about the latency of our network.
