Infrastructure Monitoring with vCenter Alarms

How to create and use alarms to monitor Hosts, VMs, Storage and more | taught by Larry Karnis

Course description

As a vSphere administrator it is critical that you identify any issues with your environment before they impact Virtual machine state, performance or availability. vCenter Server actively monitors the state, health, resource consumption and other properties of all inventory items. We can use vCenter's Alarm service to notify us of exceptional situations and take pre-emptive action well before they become a problem.

In this course we will learn:

  • About the importance of inventory monitoring and notification
  • How to create custom alarms on inventory items we care about
  • The alarm triggers available to ESXi hosts, Virtual Machines and Datastores
  • How we can customize alarms by setting both Go-To-Yellow and Go-To-Red thresholds
  • How to define alarm actions that can interact with VMs, send us e-mails or SNMP alerts when exceptional situations arise
  • How to review active and past alarms
  • To configure vCenter to allow it to send notification e-mails and SNMP traps to our network trap receiver
  • Alarm best practices

By creating alarms and setting appropriate alarm actions and responses, you can stay on top of your vSphere environment and ensure that problems are quickly identified and fixed.

Get VMware vSphere & View Training... for less!

What do you do if you need to learn VMware but can't afford the $4,000 - $6,000 charged for authorized training; or you can't find a training event that works with your schedule? Now, you can enroll in my equivalent VMware vSphere 6 and Horizon View video-on-demand training... for less.

I have created courses that together offer over 36 hours of VMware vSphere 6 lectures (about 8 days of instructor lead training at 4hrs lecture per day normally offered in live instructor led training). With Video-On-Demand training, I can provide more insight and detail, without the time constraints that a normal instructor led training class would impose. My goal is to give you a similar or better training experience than classroom training - at about 10% of the cost.

About Me

I am an Information Technology consultant / trainer with over 25 years of experience in system administration, networking, security, infrastructure and security.

I worked for 10 years as a UNIX programmer / consultant before moving to Linux in 1995. I started working with VMware products in 2001 and decided to focus exclusively on VMware in 2004. I earned my first VMware Certified Professional (VCP) designation on ESX 2.0 in 2004 (VCP #: 993). I have also earned VCP in ESX 3, and in vSphere 4 and 5.

My VMware Work Experience

  • I have been providing VMware consulting and training for more than 12 years. I have lead literally hundreds of classes and taught thousands of people how to use VMware. I teach both introductory and advanced VMware classes.
  • I worked for VMware as a senior contract VMware Certified Instructor (VCI) and consultant for almost 5 years. One of my regular duties was to help mentor new VCI's - helping them prepare for and successfully deliver vSphere classes.
  • After leaving VMware, I launched my own training business focused on VMware virtualization in 2008. In 2013, VMware called me back to help them ramp up support services for the upcoming vSphere 5.1 product launch.
  • Prior to VMware, I worked as a contract consultant / trainer for RedHat (I hold RHCE, RHCI and RHCX), Global Knowledge, Learning Tree and many other training and consulting companies.

I hold a Bachelor of Science in Computer Science and Math from the University of Toronto. I also hold numerous industry certifications including VMware Certified Professional on VMware Infrastructure 2 & 3 and vSphere 4 & 5 (ret.), VMware Certified Instructor (ret.), RedHat Certified Engineer (RHCE), RedHat Certified Instructor (RHCI) and RedHat Certified Examiner (RHCX) as well as certifications from LPI, HP, SCO and others.

I hope to see you in one of my VMware classes very soon... If you have questions, please contact me directly.
