Setting up xymon client

adduser --disabled-login xymon
cd /usr/src
wget http://downloads.sourceforge.net/project/xymon/Xymon/4.3.3/xymon-4.3.3.tar.gz
tar -zxvf xymon-4.3.3.tar.gz
cd xymon-4.3.3
./configure.client

(config=server)
(user=xymon)
(home=/home/xymon)

make
make install
su - xymon -c "/home/xymon/client/runclient.sh start"

Install MySQL/Apache Montioring on client

1. Create a mysql user 'monitoring', eg:

CREATE USER 'monitoring'@'localhost' IDENTIFIED BY 'monitoring';

2. Install ext scripts::

cd /home/xymon/client
cvs -d:pserver:anon@cvs.hamish.geek.nz:/cvs co -d ext xymon-ext
chown xymon:xymon ext -R
chmod 700 ext -R

Set mysql password in the file:

bb-mysql.pl

Edit disk device in the files:

diskreads.sh
diskwrites.sh

Add lines to /home/xymon/client/etc/clientlaunch.cfg
