VMTN Blog AppSpeed on Communities Roundtable podcast #25

The Lastesting VMTN blog, VMware Communits Roundtable Podcast is out, AppSpeed on Communities Roundtable podcast #25 http://blogs.vmware.com/vmtn/2008/11/appspeed-on-com.html

“The topic today was VMware AppSpeed, which began life as B-hive Conductor. From the website: “The product “provides virtual infrastructure groups visibility into the multi-tier applications (performance, usage and dependencies) running across both virtual and physical infrastructure.” I think it’s another example of how you can do something better virtually by sitting outside the VM — something that would be either impractical, much harder, or hopelessly tied to the OS if you were doing it with an agent inside a physical machine.”

How to setup SYSLOG’s in VMware EXSi

I wrote this up from the documentation, and it seems to work ok, even through I have not had a chance test it well.

Install remote CPL for vmware

CMD to C:Program FilesVMwareVMware VI Remote CLIbin>

——— Set syslog server

C:Program FilesVMwareVMware VI Remote CLIbin>vicfg-syslog.pl –url https://ipaddressofserver/sdk/webService –setserver ipaddressofcentralsyslogserver

Enter username: root

Enter password:

—————- Dispay settings

C:Program FilesVMwareVMware VI Remote CLIbin>vicfg-syslog.pl –url https://ipaddressofserver/sdk/webService –show

This should allow you to send syslog’s to somthing like Zenoss or a central syslog server.

Now, trying to get the syslog server to understand the traps, that is what I will be working to figure out….

ESXi 3.5 U3 on USB Key

Yellow bricks posted a great blog on making a bootable usb of ESXi.

I took the latest version of ESXi 3.5 U3, and applied it to the post, and it worked great.

Seems to take about 800 MB of space.

I then applied it to a HP DC7800P desktop, and it booted great!

Then I found that the built in network card did not detect, so I tossed in two 3com 3c905b cards, and boom!, network connectivity, ( althrough ESXi see’s them as disconnected), it tests fine.

I then went into configuration and storage adapters, and saw that it detected the ICH9 controller, but no drives.

I found that I had to format the drives to fat32, and then it saw the drive, and I formatted it it to a datastore and it works!

I would recommend this configuration for a cheap none supported test box.

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.

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