Install HotSaNIC
HotSaNIC is a very nice tool which combines all sorts of very important system graphs into a simple and easy to understand webpage. It allows the admin to take a quick glance at the graphs to see what may or may not be working with the system. With the new APPS graph it is also possible to watch as more processes are started which can be helpful in tracking down why the server load is increasing. For instance if you see a huge load spike but you see that the number of exim processes has gone up significantly at the same time you can start to investigate. It also just provides nice graphs to look at.
I built this guide on a cPanel server but it will work fine on an ensim box as well. I don't recall the plesk mailserver off the top of my head but changing that small part will make it work great fine plesk. This guide is also posted on my website.

First, we will need to install RRDtool
-----command-----
cd /usr/local/src/
wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.0.x/rrdtool-1.0.48.tar.gz
tar -zxvf rrdtool-1.0.48.tar.gz
cd rrdtool-1.0.48
./configure
make
make install
make site-perl-install
cd ..
-----------------
Now we will install and configure HotSaNIC
-----command-----
cd /usr/local
wget http://downloads.sourceforge.net/hotsanic/hotsanic-0.5.0-pre5.tgz?modtime=1078012800&big_mirror=0
tar -zxf hotsanic-0.5.0-pre5.tgz
cd HotSaNIC
./setup.pl
-----------------
-----command-----
You will be asked a number of questions during the install script.

0 /usr/local/cpanel/bin/rrdtoolinstall
1 /usr/local/cpanel/bin/rrdtoolcheck
2 /usr/local/cpanel/3rdparty/bin
by just pressing ´ENTER´, item "0" will be selected.
select item 0 ... 2? >
Select 0, we are going to change this below anyways.
You are now back at the command prompt. (If it asks you more questions, just accept the default answers.. we are using these settings below....)
Now we are going to start the manual configuration of hotsanic.
-----command-----
cd /usr/local/HotSaNIC/var/settings
vi main
-------------------
-----command-----
press [ctrl -w] then type 'binpath' then press [enter]. Find and change this line.
BINPATH="not configured"
change to
BINPATH="/usr/local/rrdtool-1.0.49/bin"
press [ctrl -w] again then type 'webdir' then press [enter]. Find and change this line.
WEBDIR="not configured"
change to
WEBDIR="/home/username/public_html/stats/"
Note you are going to put this to someplace that is acessible to the internet. I would recommend setting it to a subdomain or a directory within a domain.
press [ctrl -w] again then type 'ctime' then press [enter]. Find and change this line.
CTIME="24"
change to
CTIME="4"
press [ctrl -w] again then type 'convertpath' then press [enter]. Find and change this line. If may already be changed, if so do not worry.
CONVERTPATH="not configured"
change to
CONVERTPATH="/usr/bin/convert"
Finally, to save and exit press [ctrl -x] Y then [enter]. At the prompt type.
pico mod-traffic
Find and change this line:
SWAPIO="no"
change to
SWAPIO="yes"
Again, to save and exit press [ctrl -x] Y then [enter]. At the prompt type.
pico -w mod_system
Go to the bottom and where you see all the IRQ= lines that are not commented out simply delete them.
Again, to save and exit press [ctrl -x] Y then [enter]. At the prompt type.
-----command-----
cat /proc/stat |grep disk_io
-----command-----
Edit the disk_io config file
-----command-----
pico -w mod_diskio
-----command-----
At the bottom add:
DEV=8_0,sda
DEV=8_1,sda
If your system has something other then the (8,0) and (8,1) as listed above make sure to put that in the config above. Again, to save and exit press [ctrl -x] Y then [enter]. At the prompt type.
-----command-----
pico -w mod_apps
-----command-----
This mod is going to allow you to track how many of a given service is running. I would say that apache, mysql, and email are the most important. Note that exim is what cPanel uses, if you are using ensim replace it with sendmail. Add the following to the bottom:
APP=httpd,Apache
APP=mysqld,Mysql
APP=exim,Exim
Again, to save and exit press [ctrl -x] Y then [enter]. Note that below when you make the directory it needs to be what you put in the configuration file above. At the prompt type.
-----command-----
cd /usr/local/HotSaNIC
mkdir /home/username/public_html/stats
./rrdgraph start
./makeindex.pl
./diagrams.pl
./convert.pl
-----command-----
You now have HotSaNIC installed
To view HotSaNIC go to http://yourIPaddress/stats/
(it will take a few mins for the graphs to generate data.
Now, Lets set HotSaNIC up so it will start when you reboot your server.
-----command-----
pico /etc/rc.local
-----command-----
Add this line:
/usr/local/HotSaNIC/./rrdgraph start
