Hi,
The following is taken from a checklist that I wrote for installing Cacti from scratch on Ubuntu 12.04 LTS servers. These are just notes for myself, without comments or descriptive details.
These instructions assume that Smokeping is installed on the same machine as Cacti.
There are probably better and more secure ways to do this, and someone should properly document them.
Code: Select all
Installing Smokeping.
sudo mkdir /var/nmid
sudo chmod –R a+wr /var/nmid
sudo apt-get install fping
sudo apt-get install echoping
sudo apt-get install sendmail
sudo apt-get install smokeping
sudo apt-get install libsoap-lite-perl
sudo chmod –R a+wr /usr/share/smokeping
sudo chmod -R a+wr /var/lib/smokeping
The URL http://<yoursmokepingserver>/cgi-bin/smokeping.cgi should now show you the smokeping website.
Install NMID plugin:
cd /var/www/plugins #This should be your Cacti's plugin directory
wget http://blog.network-outsourcing.de/wp-content/uploads/nmidSmokeping.zip
unzip nmidSmokeping.zip
rm nmidSmokeping.zip
Install and activate the plugin in Cacti's "Plugin Management".
IMPORTANT: Make sure that your user account has access permission to this plugin! Check Cacti's "User Management"!
Copy the following to a file named
/etc/cron.d/nmid:
*/5 * * * * root /etc/smokeping/nmid
Copy the following to a file named /etc/cron.d/smokeping:
*/5 * * * * root /etc/smokeping/smokecron
Copy the following to a file named /etc/smokeping/nmid:
#!/bin/sh
cat /etc/smokeping/config_header > /etc/smokeping/config.d/Targets
cat /var/nmid/smokeping_nmid_spserver1_config.txt >> /etc/smokeping/config.d/Targets
/etc/init.d/smokeping reload > /dev/null 2>&1
Make it executable via "sudo chmod +x /etc/smokeping/nmid".
Copy the following to a file named /etc/smokeping/smokecron:
#!/bin/sh
logfile=/var/log/smokeping
# Make sure that Smokeping is running.
if [ $(ps -A | grep -c smokeping) = 0 ];
then
echo .$(date) Smokeping revived. >> $logfile
/etc/init.d/smokeping restart > /dev/null 2>&1
fi
Copy the following to a file named
/etc/smokeping/config_header:
*** Targets ***
probe = FPing
menu = Top
title = Network Latency Grapher
remark = Welcome to the SmokePing website. \
Here you will learn all about the latency of our network.
+ Internet_Reference
menu = Internet Reference
title = Internet Reference
++ GOOGLE
menu = GOOGLE
title = GOOGLE - 8.8.8.8
host = 8.8.8.8
You should at least restart the CRON daemon after these changes.
Every device that is supposed to appear in Smokeping must be added to Smokeping in Cacti via "Management/Devices/Add to Smokeping...".
The CRON script "nmid" should ensure that Smokeping's configuration is automatically updated every five minutes. If it doesn't appear there automatically (which unfortunately tends to happen on some Ubuntu servers), launch the "nmid" script manually.
If anybody has suggestions for improvements, I --REALLY-- would love to hear them.
