Description

For system administrators, network engineers, and security analysts, it is essential to keep a track of network traffic. Zenoss Core is an enterprise-level systems and network monitoring solution that can be as complex as you need it to be. And while just about anyone can install it, turn it on, and monitor "something", Zenoss Core has a complicated interface packed with features. The interface has been drastically improved over version 2, but it's still not the type of software you can use intuitively – in other words, a bit of guidance is in order. The role of this book is to serve as your Zenoss Core tour guide and save you hours, days, maybe weeks of time. This book will show you how to work with Zenoss and effectively adapt Zenoss for System and Network monitoring. Starting with the Zenoss basics, it requires no existing knowledge of systems management, and whether or not you can recite MIB trees and OIDs from memory is irrelevant. Advanced users will be able to identify ways in which they can customize the system to do more, while less advanced users will appreciate the ease of use Zenoss provides. The book contains step-by-step examples to demonstrate Zenoss Core's capabilities. The best approach to using this book is to sit down with Zenoss and apply the examples found in these pages to your system. The book covers the monitoring basics: adding devices, monitoring for availability and performance, processing events, and reviewing reports. It also dives into more advanced customizations, such as custom device reports, external event handling (for example, syslog server, zensendevent, and Windows Event Logs), custom monitoring templates using SNMP data sources, along with Nagios, and Cacti plugins. An example of a Nagios-style plugin is included and the book shows you where to get an example of a Cacti-compatible plugin for use as a command data source in monitoring templates. In Zenoss Core, ZenPacks are modules that add monitoring functionality. Using the Nagios plugin example, you will learn how to create, package, and distribute a ZenPack. You also learn how to explore Zenoss Core's data model using zendmd so that you can more effectively write event transformations and custom device reports.

Who is this book for?

This book is written primarily for network and systems administrators who are monitoring their IT assets with Zenoss Core or who plan to monitor them. In reality, this book will benefit anyone, regardless of job title, who recognizes the importance of proactively monitoring the servers, routers, computers, websites, and devices that connect companies to customers.

What you will learn

Discover devices and prepare your monitoring environment
Set up, model, and configure devices
Monitor availability and performance

System monitoring is a hot topic if you are trying to deliver a stable environment for your users or clients. There are many options out there that are capable of letting administrators know when a system is down or at risk for example Solarwinds is one of the popular monitoring applications today. But there are some new names in the ring and this time they come from the open source community so there is a free version for all to use, this is Zenoss Core a robust community driven snmp application. I just finished reading the new technical book on the latest version of Zenoss Core put out by Packetpub to see how well it does to get you running your own Zenoss Core server.To follow along with the book Zenoss offers a downloadable VMware appliance with the application already installed and it comes for Windows, Linux and OS X. I downloaded the OS X appliance so I could have a sandbox to play with while reading the book, I would highly recommend this so you are able to get used to the user interface.If you are thinking about installing Zenoss or already using it, this book is a must have to bridge the gap in documentation. I found the book had all the information I needed to help get my environment up and running and it was easy to follow. There are also more advanced topics covered such as ZenPack add ons. ZenPacks are one of Zenoss's most exciting feature, they are community derived and shared through the Zenoss website. You will find thousands of ZenPacks which are completely customized to monitor very specific devices, a couple of examples would be apache web servers, asterisk voip servers, and pretty much any server-based application or device else you can think of. Users create a ZenPacks then upload to share with the community, this is a great use of the open source community to help us all make sure our servers have the highest uptime.Overall I would recommend this book to anyone looking for a snmp application since Zenoss Core is an open source application and has the best price tag of all, free. Before starting to look at expensive snmp systems do yourself a favor and read this book to see how well Zenoss does with monitoring servers.
