Is a free and monitoring solution similar to. It can be used to monitor all sorts of hardware and in case of failures sends out alerts to recipients. Zenoss Core provides a web interface that allows system administrators to monitor availability, inventory/configuration, performance, and events. Compared to (my personal opinion) has alot higher minimal hardware requirements and it is quite a RAM hog, so be sure you meet the requirements if you want your instance to run smoothly. Install Zenoss Monitoring Server Minimal Hardware Requirements: • Small Deployments (1 to 250 Monitored Devices) • 4GB RAM • 2 CPU Cores • 1x 300GB, 10K RPM Drive • Medium Deployments (250 to 500 Monitored Devices) • 8GB RAM • 4 CPU Cores • 1x 300GB, 10K RPM Drive • Large Deployments (500 to 1000 Monitored Devices) • 16GB – 32GB RAM • 8 CPU Cores • 1x 300GB, 15K RPM Drive Let’s Install Zenoss Monitoring Server on CentOS 6!

Disable SELinux and IPtables For this guide SELinux and IPtables were completely disabled and CentOS 6 was up-to-date! Add DNS FQDN Entry and NTP Sync To ensure proper resolving FQDN entries in DNS or /etc/hosts must exist and please configure NTP time synchronization for services to run properly. Install Following Packages Install the following packages to make your life a bit easier – especially if you are on CentOS 6 minimal install.

It will help us resolve all of the dependencies required to install and run Zenoss. [root@centos1 ~]# rpm -ivh 5. Install MySQL Repository Zenoss requires MySQL database server.

We will download and install the latest MySQL server version available. [root@centos1 ~]# rpm -ivh 6. Download and Install Oracle Sun Java Download the latest Oracle Sun Java RPM from and transfer it to your server. Zenoss needs Oracle Java to run. Please install Oracle Sun Java RPM as follows. [root@centos1 ~]# rpm -ivh jre-7u60-linux-x64.rpm Preparing. ########################################### [100%] 1:jre ########################################### [100%] Unpacking JAR files.

Remove existing java links and recreate them, pointing to Oracle Sun Java binaries. [root@centos1 ~]# rm /usr/bin/java /usr/bin/javaws rm: remove symbolic link `/usr/bin/java'? Y rm: remove symbolic link `/usr/bin/javaws'?

Y [root@centos1 ~]# ln -s /usr/java/latest/bin/java /usr/bin/java [root@centos1 ~]# ln -s /usr/java/latest/bin/javaws /usr/bin/javaws Check and make sure you are running Oracle Sun Java. [root@centos1 ~]# java -version java version '1.7.0_60' Java(TM) SE Runtime Environment (build 1.7.0_60-b19) Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode) 7. Install and Start Latest MySQL Server Install the latest version of MySQL server and start it but DO NOT set MySQL server root password yet! This will enable Zenoss to automatically populate MySQL database. [root@centos1 ~]# yum install mysql-community-server [root@centos1 ~]# /etc/init.d/mysqld start 8.

Download and Install Latest Zenoss RPM Download latest Zenoss RPM to your server and install it via “yum” to resolve dependencies.
