While VMware vRealize Operations Manager makes use of a Gemfire database and vRealize Hyperic makes use of vPostgress, VMware vRealize Log Insight makes use of Cassandra. You might wonder why knowing that even matters. Well, as I’ve seen again this week, the database engine that drives each of these products essentially dictates the design and deployment of their environments and their limitations.
This week, we had a situation where our newly deployed Log Insight cluster wasn’t performing. In fact it was so bad, that it took 20 – 30 minutes to simply log into the admin interface. Yet the CPU and Memory usage counters for each of the appliances weren’t even being tickled. It was a strange issue for sure, and by 5pm on Monday 31st of August, we were in the process of logging a P1 call with VMware support.
I am happy to announce that our new book, VMware vSphere Performance (ISBN: 9781118008195) is now available on Amazon.com and Amazon.co.uk in eBook format on Kindle as well as Paperback. The Paperback version should be in stock at Amazon.com by 12 May 2014.
This title was first announced in 2011 and due to a number of issues and difficulties, the book was delayed several times. However, due to the hard work and dedication of my co-authors, Matt Liebowitz, Christopher Kusek and the editorial team at John Wiley & Sons, Inc. we were able to finally bring the title to print.
