Performance charts fail after Daylight Savings changes are applied

November 5th, 2010 by jason No comments »

Daylight savings changes this weekend allow many folks to get an extra hour of sleep.  However, a VMware vSphere 4.1 bug has surfaced which may spoil the fun. 

VMware has published KB 1030305 (Performance charts fail after Daylight Savings changes are applied) which serves as a reminder that the pitfalls and treachery of mixing daylight savings changes and million dollar datacenters are not behind us yet.  Those who are on vSphere 4.1 and observe the weekend time change will run into problems come Sunday morning:

After Daylight Savings settings are applied:

  • Performance charts do not display data
  • Past week, month, and year performance overview charts are not displayed
  • Datastore performance/space data charts are not displayed
  • You receive the error: The chart could not be loaded
  • This occurs when clocks are set back 1 hour from Daylight Savings Time to Standard Time

VMware offers the following workaround:

Use Advanced Chart Options:

  1. Click Performance
  2. Click Advanced
  3. Click Chart Options and then choose the chart you want to review

Use a custom time range when viewing performance charts after clocks are set back:

  1. Click Performance
  2. Click the Time Range dropdown
  3. Choose Custom
  4. Specify From and To options that exclude the hours for when the time change occurred

For example:

If Standard Time settings were applied on November 7, at 01:00 AM, you could use these ranges:
Before the time change:
From 1/11/2010 12:00 AM To 7/11/2010 12:00 AM
After the time change:
From 7/11/2010 03:00 AM To 8/11/2010 15:00 PM

Have a great weekend!

Hyper9 Pulse Check

November 5th, 2010 by jason No comments »

SnagIt Capture

It has been several months since I’ve written about Austin, TX based Hyper9. I know they’ve been hard at work with continuous development of their flagship Hyper9 management product in addition to a strong nationwide marketing campaign.  Just last spring they presented at a quarterly Minneapolis VMUG meeting here locally.

What’s the latest news in the Hyper9 camp?  I’m glad you asked…

Leadership Updates:

  • 27-year veteran Bob Quillin joins Hyper9 as Chief Marketing Officer.  Quillin was formerly with VMware where he led vCenter virtualization and cloud management solution marketing for the configuration and compliance management product lines.  Bob has a background comprised of enterprise, systems, application, and network management, including tenure at storage giant EMC.
  • Greg Barone joins Hyper9 as Vice President of Worldwide Sales.  Greg’s 18-year background is in sales and sales management for tech companies ranging from startup to multi-billion dollar enterprises.  He held the role of V.P of Worldwide Sales at Cognio (a Cisco acquisition).

Q3 2010 Highlights:

  • Q3 revenue doubled over the prior period and represents Hyper9’s best performance to date.
  • 400% year-over-year revenue growth with revenue doubling each quarter this year.
  • A broad range of new business from customers of various sizes and verticals.
  • Successfully road tested at large scale in enterprise deployments consisting of tens of thousands of VMs.
  • Introduction of Cloud Cost Estimator Lens which provides comparisons to providers such as Amazon EC2.
  • New partner alliances designed to catapult Hyper9’s growth into global markets

This sounds like great news for Hyper9.  As someone who has been involved with Hyper9 product development in the earlier stages, it has been fascinating to watch this company evolve into a successful ecosystem partner.

Do you use Hyper9?  What do you think of the product?  I’d like hear your honest opinion of the product and so would Hyper9.

SexyBookmarks WordPress Plugin and RSS Feeds

November 4th, 2010 by jason No comments »

Wednesday night I wrote up a blog post on Veeam Backup and Recovery 5.0 and scheduled its release for this morning at 9am.  I’ve been swamped at work but I did get a chance to validate mid-morning that the post was up.  Shortly after I realized the blog’s RSS Feed had stopped working as of last night’s Veeam post.

Once home from work, I started the troubleshooting.  Due to the self-hosting aspect, IIS, MySQL, the number of plugins in use (I do try to keep to an absolute minimum), the theme mods, the monetizing, Feedburner, etc., my blog has several moving parts and is a bit of a pain sometimes.  WordPress itself is solid but with the add-ons and hacks, it can become a house of cards (it’s a lot like running a game server).  The more time that is invested in a blog, the less of an option it is to firebomb and start over.  I crossed that point of no return a long time ago.  Themes, monetization, and all that stuff aside, the content (and to some degree the comments) is by far the most valuable piece to NOT be lost.  In retrospect, solving the technical issues as they arise is satisfying and a slight boost to the ego, but often times there just aren’t enough hours in the day for these types of problems.

Troubleshooting a WordPress blog is best approached from a chronological standpoint.  Think of the blog as one long timeline of sequentially serial events.  You’ve got post history, comment history, WordPress code history, theme history, plugin history, integration history, hack history, platform infrastructure history (Windows/Linux, MySQL, IIS or Apache), etc.  Blog problems are usually going to be tied back to changes to any one of these components.  If the blog sees a lot of action, malfunctions will usually surface quickly.  “It was working yesterday, but something broke today”.  Such was the case when my blog’s RSS Feeds stopped updating this morning.  As I stated earlier, the best approach is to think about the timeline and go backwards from the point of broken identifying each change that was made to the blog.  Historically for me, it’s usually a plugin or a recent post which has some sort of nasty formatting embedded in it somewhere.

So.. the problem: RSS Feeds broken; no longer updating at Feedburner.  Impact: 3009 RSS subscribers are unaware I’ve written new content – bad for me, bad for sponsors.

Solving this problem was a treat because I had made multiple changes to the blog last night:

  1. Upgraded the theme to a new rev. (finally!)
  2. Applied existing hack functionality to new theme files
  3. Installed two new plugins
  4. Made changes to sidebar widgets
  5. Wrote a Veeam blog post which had some special characters copied/pasted in it

I started by testing my blog’s RSS feed with a syntax/format checker at Feedburner.  It failed.  There’s bad code embedded somewhere which can stem from any of the above changes.

Next I shut down Feedburner integration to help isolate the problem.  With the Feedburner plugin disabled, my blog now supplies its native RSS feed capability which is built into WordPress.  Hitting the URL for the feed showed failure.  Long hourglass followed by a blank browser page with a bit of information, again, about bad code in the feed which cannot be handled.  So now I know Feedburner is indeed not updating because of bad content in the feed (that behavior is by design which is why the internet makes feed checkers to aid in troubleshooting).

Good progress, however I’m still left with identifying which change above caused the RSS feed to stop working.  The next step is to start backing out the above changes.

  1. I started by unpublishing the Veeam post.  No dice.
  2. I then rolled back to the old version of the theme.  Problem still exists.
  3. Then I disabled the SexyBookmarks plugin.  B-I-N-G-O

Shortly after, I found specifically what in the plugin was causing the RSS feed issue.  There’s an option in the plugin settings called Show in RSS feed? (displayed in the image below)  This feature is designed to show the little social media information sharing buttons in RSS feeds when set to Yes.  Whether or not I had configured this option, it was configured as Yes.  When set to Yes, it embeds code in the RSS feed which RSS readers don’t understand, which then leads to RSS feed failure.  With this find, I could disable the feature but at the same time,  keep the plugin enabled.

I can’t say I learned a great deal here.  It was more reinforcement of what I’ve learned in the past.  I’ve been through blog troubleshooting exercises like this before and they were solved using the same or similar techniques.  Blog plugins and modifications ship with the implied warranty of “buyer beware”.  When something goes wrong with your blog, you should be able to tie the problem back to recent changes or events.  In an environment such as mine where I’m the only one making changes and writing content, I’m accountable for what broke and I can isolate the problem to something that I did to cause impact fairly quickly.  Larger blogs hosted somewhere else with multiple owners and authors introduces troubleshooting complexity, particularly if changes aren’t documented.  I guess that’s why change management was invented.  My lab is the last environment I’m aware of where changes can be made without a CR.  That’s one of the reasons why the lab remains so sexy and is such a great escape.

Veeam Backup & Replication 5.0

November 4th, 2010 by jason No comments »

Back in July of this year, I attended Gestalt IT Tech Field Day in Seattle.  You may recall that I was the recipient of a presentation from Veeam and wrote about their upcoming Backup & Replication product and new vPower technology. 

Backup & Replication 4.0 had already been known as a category finalist at last year’s VMworld conference.  Veeam was not content in the runner up position. In September, the Columbus, Reading, and Sydney based organization showcased their new development at VMworld 2010 San Francisco and walked away with Best of Show and Best New Technology.  I can tell you as an attendee of the conference for several years that the competition in the Solutions Exchange is rivaled by nothing else that I’ve ever seen before.  For Veeam to win as they did in these categories is a pretty big deal.  I know they are both excited and proud about this year’s results.

In October, Veeam released Backup & Replication 5.0 to the public.  Companies of all sizes can now leverage the technology and realize the features, efficiency, and savings Veeam brings to the table.

So what’s baked into 5.0?  Veeam B&R alumni will find a significant portion of what made previous versions so great.  At a high level,  2-in-1 data protection for VMware virtual infrastructure: Backup and Replication features consolidated into a single no-nonsense solution.  New in version 5 you’ll find the following:

1. Instant VM Recovery: Restore an entire virtual machine from a backup file in minutes. Users remain productive while IT troubleshoots the issue.

2. U-AIR™ (Universal Application-Item Recovery): Recover individual items from any virtualized application, on any operating system, without additional backups, agents or software tools. Eliminates the need for expensive special-purpose tools and extends granular recovery to all applications and users.

3. SureBackup™ Recovery Verification: Automatically verify the recoverability of every backup, of every virtual machine, every time. Eliminates uncertainty and sets a new standard in data protection.

4. On-demand Sandbox: Create test VMs from any point in time to troubleshoot problems or test workarounds, software patches and new application code. Eliminates the need for dedicated test labs and the overhead that extra VMware snapshots place on VMs.

5. Instant File-level Recovery for any file system: Recover an entire VM or an individual file from the same image-level backup. Extends instant file-level recovery to all VMs.

Personally, I’ve been accumulating quite a bit of experience with Veeam Backup & Replication.  Over the past year, I have been using it to provide various levels of protection for tiers of data in my lab which myself and my family are immensely dependent on.  Last year at this time I was backing up to tape.  Those with growing data sets know that the tape model isn’t sustainable long term.  Not to mention, tape is a datacenter fashion faux pas, even for a lab environment I was catching hell about it in the social media streams.  Now the tape library is gone, the lab is 100% virtualized and Veeam backs up all of it.  Included in that figure is data which I cannot put a price on: well over a decade of my technical work, financial and tax data, and 81GB of family pictures and videos which are irreplaceable.  Today, Veeam is the provider which I trust as the sole safety net between peace of mind and utter disaster.  Beyond its intrinsic functionality,  I used Veeam Backup & Replication as a solution in my VCDX design submission and successfully defended it last February.  Assuming it fits the business requirements and design constraints, it’s a solid choice in a VMware virtualized datacenter.

As I said before, version 5 is currently shipping.  List price starts at $599 USD per socket for Standard Edition and $899 USD per socket for Enterprise Edition.  If you’ve been carrying B&R maintenance as of 6/30/10, you’re already eligible for a free upgrade to Enterprise Edition.

If that weren’t enough to tantalize your tentacles, Veeam is honoring a Competitive Upgrade program through 12/24/10.  New customers receive a 25% discount on the price of Standard or Enterprise Edition with proof of purchase of another backup product.

VMware KB Mobile App Launched

November 3rd, 2010 by jason No comments »

Got an Apple iPhone, iPad, or Android and a desire to search the VMware Knowledgebase or watch the latest KBTV videos on the go?  VMware has your covered with Monday’s launch of the VMware KB Mobile App.  Don’t head to the App Store to download this application – you won’t find it there.  It’s written in HTML 5 meaning you’ll access it like any other web page through your browser.  The link for the application is http://wbxapp.com/vmwarekb.  Following are some screens I grabbed from the iPad:

The VMware KB Mobile App home page.  You’ll find several items of interest here, some of which is dynamic content and will change over time:


Here’s a look at VMware KBTV which has been in existence for quit some time on YouTube.  I watched several vCloud Director video clips from this page:


Here we see an example of searching the Knowledgebase.  There appears to be no granular ability to confine the search to a specific forum or selection of forums.  Given VMware’s wide variety of forums, more often than not search method is going to produce results which are not desired or don’t apply.  Not good:


The search criteria Vcenter actually forwards us to the kb.vmware.com site and yields 300 results, presumably across all product and discussion forums:


Many people have handheld devices which are already HTML 5 compatible or soon will be (Blackberry for example).  This app is FREE.  Take it for a spin and provide feedback to VMware so that they can build in more usefulness in future versions.

vCenter MAC Address allocation and conflicts

November 3rd, 2010 by jason No comments »

Paul Davey of Xtravirt published a VMware networking article a few weeks ago called vCenter MAC Address allocation and conflicts.  The article describes the mechanism behind MAC address assignments in vCenter, and more specifically how conflicts are avoided:

When a vCenter server is installed a unique ID is generated. This ID is randomly generated and is in the range of 0 to 64. The ID gets used when generating MAC address and the UUIDS, or unique identifiers for virtual machines. You can see that if two vCenter servers had the same unique ID, a possibility exists that duplicate MAC addresses might get generated; cue packet loss, connectivity issues and your desk phone ringing a lot…

I receive email updates from Xtravirt at regular intervals – about one every week or two.  Each update contains new virtualization content as well as links to their most popular content.  I find the content very interesting and always look forward to opening new email from them.  I think this speaks volumes considering how much of a chore email can be at times.  If this sounds appealing to you, head to their site and look at the bottom of the page to sign up for the Xtravirt Newsletter.   No purchase or invitation necessary.

Updated 3/14/11: I thought this might also be helpful for this article.  VMware explains the automatic MAC address generation process as follows:

The VMware Universally Unique Identifier (UUID) generates MAC addresses that are checked for conflicts. The generated MAC addresses are created by using three parts: the VMware OUI, the SMBIOS UUID for the physical ESXi machine, and a hash based on the name of the entity that the MAC address is being generated for.
