Quickguide: Observium installation on SLES11

Posted on January 24, 2012. Filed under: Linux, OSS | Tags: , , |

I came accross a great tool for collecting data called Observium, it works with mysql+php+rrdtool collecting data through SNMP. Here are my notes based on original Debian+SVN guide.

Initial Repos

SLES11 + SLE11-SDK + Updates

Pre-requisites

# Additional repositories

zypper ar -f http://download.opensuse.org/repositories/network:/utilities/SLE_11_SP1network:utilities

# Prepackaged installation

zypper in apache2-mod_php5 php5-mysql php5-gd php5-snmp php5-pearnet-snmp graphviz-gd graphviz subversion mysql rrdtool fpingImageMagick whois mtr nmap ipmitool

# Additional modules using PEAR

pear install Net_IPv6pear install Net_IPv4

# For monitoring VMs using libvirt

zypper in libvirt

# Checkout of Observium from SVN

cd /optsvn co http://www.observium.org/svn/observer/trunk observium

Data Base

# DB+user Creation

mysql> create database observium;

mysql> grant all privileges on observium.* to ‘observium’@’localhost’   -> identified by ‘<pass>’;

# Schema creation

cd observium

mysql -u observium -p observium < database-schema.sql<pass>

# Update config.php to include DB connection info

cp config.php{.default,}

vi config.php

# Schema updates

for F in database-update*;do scripts/update-sql.php $F;done

# RRD and graphs directory creation

mkdir graphs rrdchown wwwrun: graphs/ rrd/

PATHS

# fping

vi config.php

$config[‘fping’] = “/usr/sbin/fping”;

Apache

# Enable Mod Rewrite

a2enmod rewrite

# apache vhost configuration

vi /etc/apache2/vhosts.d/

observium.conf

<VirtualHost *:80>

 DocumentRoot /opt/observium/html/

ServerName  observium.<domain>

CustomLog /opt/observium/logs/access_log combined

ErrorLog /opt/observium/logs/error_log

    <Directory “/opt/observium/html/”>

        AllowOverride All

        Options FollowSymLinks MultiViews

        Order allow,deny

        Allow from all

</Directory>

</VirtualHost>

# Log destination directory

mkdir /opt/observium/logs/

chown wwwrun: /opt/observium/logs/

# Startup

rcapache2 startchkconfig apache2 on

##
# Users (for production, better configure LDAP)
##

# Admins, level 10

/opt/observium/adduser.php user1 pass 10

Devices

# Adding new devices

cd /opt/observium/ && ./addhost.php <hostname> <community> v2c

# Discovery inicial + colecta de datos

./discovery.php -h all

./poller.php -h all

# Enable data collection using cron

vi /etc/cron.d/observium

Performance Tunning
# Install XCache, rebuild package from OBS as it’s not for SP1

mkdir ~/tmp
cd ~/tmp
wget http://download.opensuse.org/repositories/server:/php:/extensions/SLE_11/src/php5-xcache-1.3.2-2.1.src.rpm
rpmbuild –rebuild php5-xcache-1.3.2-2.1.src.rpm

# Install result from above command

# Restart apache

rcapache2 restart

That’s all, the same procedure should work with openSUSE, given you use the right repositories…
