Zenoss Core Network and System Monitoring book review.

In September I reviewed, Zenoss Core Network and System Monitoring

I have not had a chance to post it on my blog, as I have been busy.

But here is my review, which I have also posted on amazon.com, Here.

Zenoss Core: Network and System Monitoring is a complete step by step guide to getting the most out of Zenoss Core 2.1

The book starts with a detailed Preface of what Zenoss Core is, and what it can do for a System Admin. Then after lesson on the design of Zenoss Core, the book starts to walk you through a installation. This book covers even covers a VMware player install. It also shows you how to install under your favorite flavor of Linux, included are directions for Red Hat, CentOS, Fedora Core, Free BSD, MAC, and Debian/Ubuntu.

They even show the proper method to get Zenoss Core to automatically start up under Red HAT and Debian/Ubuntu.

Furthermore, the author shows you how do the configuration under Linux for both Firewall and SNMP with Zenoss Core, and how to do WMI and SNMP configurations under windows.

I really think the book does a nice job of guiding a user through the Web Interface of Zenoss core, where detailed steps are taken for you to understand how to add devices and configure Zenoss Core to monitor them correctly.

Detail by the author has been made to walk you through the Device ZProperties, and Status / Performance Monitors of the system.

Now the real power of Zenoss Core is Event / device alerting, and this is a fantastic deliberation of how to set up device event alerting.

Finally the book provides you with a how to for device and system reporting and even gives you a chance to extend Zenoss Core to meet your needs.

For those of you that want a good guide to Zenoss, it’s a great place to start.


Xiotech 3D 4000

We have been looking at the Xiotech 3D 4000, and here are some product links we were given by the vendor.



After some review, I think it lacks in some areas compared to Equallogic, EMC, and Netapp, more to come on them.

Netware 6.5 on VMware @ Malaysia Communities by craig

craig posted a Netware 6.5 on VMware @ Malaysia Communities.

I had recently setup a development environment to verify the potential of migrating the existing age servers which running with Netware 6.5 from physical to virtual. The reason of doing this is purely due to the expiration of our server life cycle, and potential to reduce the capex requirement for replacing with new servers. As we know that the netware 6.5 will not able to utilize the quad cores processing power which is consider a common servers resources today.”

I thought this was useful for those of you out there running Netware 6.5, and getting into VMware.

ESXi Free or Licensed?

We have been running ESXi, since it has been released as free.

But we have just started to think about licensing, with some research, I found this.

VM/ETC ( http://vmetc.com ) writes about ESXi licensing.

Yes, VMware has made a version of it’s Enterprise class, bare metal installable hypervisor available for download at no charge. There is no trial period or demo license required. There are no guest limitations on the host. So, there has to be a “gotcha”, right? Not really, but you do need to understand the differences between the free ESXi and VI ESXi (licensed) versions.

Here is the full article. ( http://vmetc.com/2008/08/10/whats-the-difference-between-free-esxi-and-licensed-esxi/ )
