As you can see, Microsoft means business and is on top of things. SCA has been upgraded. Many new features/functionality have been added, like:
Even though it might seem small compared to all the products/services portfolio Microsoft offers to their customers, don’t forget that SCA is a young product. So the thrust behind it is huge, thus making its potential enormous.
Of course, much of it is kept secret. But Microsoft is also proud about their achievements which is totally understandable. So they have put together some videos and animations about their state of the art datacenters.
This is one of those videos. It shows clearly the approach Microsoft has chosen for its datacenters. Very interesting it is. Since the video isn’t technical at all, it is targeted at a broad audience. Enjoy!
I’ve seen this error many times in the past with SCOM RTM/SP1 based environments in conjunction with Windows 2003 DCs and domains which were on Windows 2000 mixed functional level. In cases the issue was solved easily by following the procedure in KB331951.
But this bug isn’t gone at all. In SCOM R2 environments, on the latest CU level and placed in Windows 2008 based domains/forests, this error message is still there. And the earlier mentioned KB331951 doesn’t help here.
It happens for users who have been assigned the Read-Only Operators Role in SCOM. When users like these have the SCOM Console open and a new Alert is shown, the above mentioned EventID is shown in the OpsMgr event log.
Some searching on the internet showed that other people were affected by the same bug as well and even a bug report had been filed about it. But that bug report isn’t to be found anymore.
So I filed a new bug report, to be found here. When you’re affected by this bug, please vote so the more change it gets to be addressed.
The purpose of this sample is to illustrate a logical approach for analyzing an actual application and stepping through a process for defining its monitoring requirements. The structure of the document can be used as a template for designing a management pack for your own application.
The document can be downloaded from here.
That’s bad. Really bad. Not only the restarting, but also the word ‘may’. Sounds like Russian Roulette and thus influencing Change Management in a negative kind of way.
Since a day or so, Microsoft has published a KB article (KB2526113) in which they acknowledge the issue, describe the causes and how to work around it. It is to be expected that will be solved in a future CU for SCOM R2.
Event Type: Error
KB2526827 describes above mentioned issue, the cause and how to solve it.
This is a known issue and will be fixed in a future edition of the MP. For now Microsoft has published a workaround, to be found here.
Hope this helps.
It is evident that the installation method for Opalis Operator Console comes from an age where installations like these were default and done by real specialists/geeks who had time for such tedious tasks. But hey, the dinosaurs died some time ago, so this installation has to go where it belongs: to the museum!
So it is good to see that Kelverion has made a utility which automates the installation of the Opalis Operator Console. And I must say, it works like a charm! Hello 2011 and goodbye 1970’s! Why?
Of course, this tooling has some requirements in order to run:
But when all is there it is simple point and click and Kelverion will take care of the rest! Nice and easy. So when you’re about to install Opalis WITH the Operator Console AND you want to save yourself a lot of time AND frustration? Download the tool and be happy!
The cloud comes in many shapes and formats, like IaaS, Paas & SaaS. Also the formats can be different, like public, private, hybrid and community based. Even though this blog isn’t about the cloud, there is no doubt that it will affect SCOM as well. The question isn’t when nor why but more like how?
The first steps in moving SCOM into the cloud have been made. What started under codename ‘Atlanta’ has been rebranded into Microsoft System Center Advisor (SCA).
At the moment it supports:
How it works? I have borrowed this diagram from Stefan Strangers weblog. Thanks Stefan!
Basically SCA works along the same lines as SCOM. MPs are required, Agents and Gateways. Since Kerberos can’t be used here, a certificate will be generated on the fly while the Agent is pushed out to the server being monitored by SCA. On premise the customer will install a Gateway Server which communicates with SCA in the cloud and the monitored servers on-premise. The MPs are already present in the cloud and need no further attention.
For now SCA isn’t meant for real time monitoring like SCOM. Why? It is aimed at assessment of the configuration of the monitored servers. This assessment runs on periodic basis. SCA collects data on intervals of 4-8 hours. This data is analyzed once per day and uploaded to the cloud once a day. So no real time monitoring (for now that is).
However, the assessments are based on best practices. So when you want to know whether your servers are up to specs, based on BPs, SCA can tell you that.
When you want to test drive the Release Candidate of SCA, go here. All you need is a Windows Live ID. The installation is pretty straight forward.
SCA and the Future
For now SCA supports a limited set of systems/services. But that will most certainly grow in the future as well as the functionality. So for me the question is not whether SCA will deliver SCOM functionality (real time monitoring) but when.
To be continued…
Cloud and more
I look upon myself as a consultant who is at the moment specialized in SC products and especially SCOM. But ICT is an ever changing landscape. So in order to stay in business, I have to change as well. Even better, to embrace it. And to be frankly, that’s why I like ICT. Never ever a dull moment. Because the cloud is becoming BIG and all major companies are aiming at it (Microsoft will target this year +90 % of it’s total R&D budget to the cloud…) I have to take a deeper dive in it as well.
I have made that plunge and it is awesome. Even to such an extend that I am working on a new blog, all about the cloud. Don’t know when it goes live, but it certainly will. Here a sneak preview of the placeholder:
More and more SC products will move towards the cloud. First steps might seem small, but soon it will gain momentum and grow rapidly. Another thing to look at is Windows Intune, a cloud based management solution for managing Windows 7 based systems. As you can see, the sky is getting crowded…

@Cameron and his son: a job well done! Awesome! This makes me really wonder what the GUIs will look like after ten years or so.
To have SCOM send some of those Alerts out as Notifications, whether as e-mail, sms, pager or whatever Channel you prefer, is another ballgame. Many times it just works. Other times, it might become cumbersome and Notifications don’t go out anymore, or just partially. So now what?
What are the causes, and how to troubleshoot them? Or how to setup SMS or IM? Or how to use Twitter? There are a lot of good KBs and postings out there in order to aid you in getting things up & running again. In this posting I have grouped them together, in order to provide you with a single starting point.
How To Test & Setup
How To Troubleshoot
Many subscriptions were in place and functional. One subscription did not work however. Alerts were shown in the Console, but the Alert wasn’t send out. Time to investigate the Subscription which should do that.
Opening the Subscription wasn’t a problem, but when the Criteria option was selected this error was thrown: Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).
It turned out that the Criteria was based on a Rule which was changed after the subscription had been made. Normally all is just fine, but the Rule was deleted and then rebuild. So the Subscription didn’t know anymore what Rule to target.
After having deleted the Rule and rebuild it, targeting it against the new Rule, all is fine again. Searched the internet as well for other causes of this error. What it basically comes down to is this error will happen when a Subscription has been made and:
All these reasons do have the same underlying cause: a new GUID will be generated for the items mentioned before (Rule/Monitor, Subscriber, Channel) which won’t match the one in the earlier made Subscription. Therefore the Subscription will be broken and malfunction.
Of course, changing an existing Rule/Monitor, Subscriber, Channel won’t change the GUID. But recreating it will do so.
The message was clear and simple: For them there was only one ketchup, the one from Heinz. Nothing else.
Heinz, SCOM & VMware
Looking at SCOM in conjunction with monitoring VMware there is – if you ask me – the same situation going on. Yes, there are multiple vendors offering monitoring solutions for VMware and hooking it up to SCOM.
But the Heinz experience for me personally is the one coming from Veeam. Why?
Monitoring VMware with SCOM
As we all know a VMware based environment is far from simple. It consists out of one or more storage solutions, network layers, physical servers (working in concert) which are the hosts for all the VMs, the control layer (vCenter) and the lot.
Covering all these aspects in SCOM isn’t easy. And VMware hosts are picky when it comes down to installing (additional) software. So you want to hook up SCOM to it, but in such a way that it doesn’t create any additional burden nor requires the installation of additional software on any host or guest.
Also, you don’t want to introduce an additional framework which needs serious maintenance, planning and studying of your staff in order to understand and manage it. After all, you installed SCOM to reduce the workload and not to make it more heavier.
On top of it all, the complexity of monitoring a VMware environment must kept away from you and your staff. You only want to put a thermometer into VMware and have SCOM report on it. Period. Whether it’s about the storage, the VMs or the hosts, the CPUs, physical or virtual, you want to KNOW what is happening. And again, all the complexity must be out of sight and yet you want to know it ALL of your virtualized environment.
And it must be scalable. Whether you run two VMware Hosts or 250, it must be covered by the monitoring solution. The installation must be straight forward and well documented. So the complex stuff is kept away from you while SCOM will show an in-depth view of the status of your VMware environment.
For me, and many of my key customers running VMware environments and SCOM, have found the solution with Veeam. It rocks! All above mentioned issues are addressed. So I am a believer when it comes down about how to monitor VMware with SCOM. No questions there.
Seeing is believing
But how to convince the customers? Of course, I can be very enthusiastic about good products. Can tell them a lot about it. But seeing is believing. So I can show them a real life environment with VMware and SCOM. But that means traveling, planning and the lot.
Wouldn’t it be nice to show Veeam and SCOM from my laptop? My laptop is Windows 2008 R2 SP1 based, so running a VM isn’t an issue at all. But running one or more VMware Hosts from it isn’t possible. So how to go about it?
Veeam has released a zip file (one has to contact Veeam in order to obtain it) known as Veeam nworks Demo. What it contains, or more important, what it does? Taken directly from the included guide:
‘…to allow the demonstration of the nworks Management Pack for VMware when there is no access to a running live VMware system to provide the monitoring data. nworksDEMO will ‘spoof’ as a genuine nworks Collector server, and will run standalone . With no connection to any VMware systems it will generate monitoring data to feed the nworks Management Pack for VMware. Performance graphs, topology diagrams, and example alerts from VMware systems will be created in Ops Mgr so that the nworks Management Pack can be showcased in a very simple and repeatable way…’
Let test drive it…
Like the real tool, it is simply installed. Also two MPs need to be imported and then some waiting and patience is at order. But soon the SCOM R2 Console will populate the VMware Views:
And those are not just wallpapers. These are fully clickable, like any other real item in SCOM. Nice!
This is really great. Now I can demonstrate VMware monitoring from my laptop! And of course, a real life demo is still possible but the first impression is the most important one. No more additional travel and planning needed for that one. Nice!
What was the deal?
Some people were receiving Notifications but others weren’t. Strangest thing was that there seemed to be no logic behind it at all. So some Alerts tied to Channel A didn’t get out, but other Alerts, using the same Channel, did get out.
Things I tried but all to no avail
I tried many things, like opening all Subscriptions, cycling through all screens and save them one by one. Opened all Subscribers, looking for errors, found some, corrected them but again EventID 4503 kept on nagging me… Checked out all Channels but found nothing wrong there as well.
Found some Blog postings with Google also about the same EventID but there the Notification Model came completely to a halt and the cause was totally different, so I had another, yet undefined, cause to deal with. These are the postings I am talking about which did not help out in my particular case:
So it was time for some drastic measures:
Then I got even more drastic since it really made me a ‘bit’ frustrated, it looked like SCOM was getting ahead of me, something I do NOT like…
Lost a battle of two BUT got WISER none the less
Even though all seemed to be lost, the last time this event happened made me a lot wiser. Why? There was no more ‘noise’ present in the MP containing the Notification Model. So the actual cause was still there but easier to pinpoint. So it was time for some reasoning:
Let’s ZOOM in on the CHANNEL
Channel was pretty straight forward as well. Using two Exchange servers. Talked to the Exchange guys/girls and they told me everything was just fine there. However, I have learned my lessons the hard way about presuming. So time to test it as well.
I downloaded the Notifications Test Tool and used the configured SMTP Channel to send an Alert to my internal e-mail account. Which worked! Now one could say this is not good since the Notification Channel turned out just fine. But thing is, a Channel consists out of many components which might break or cause issues as well. So all this tool told me is that the BASIC functionality of the Channel was OK, like the configured Exchange servers. But how about the deeper configuration settings of this Channel?
Especially these configurable items of any SMTP Channel may cause some serious grief:
Configurable Item 3 wasn’t at play here since that is all about garbled mail messages. And here, the issues occurred before a mail message was even
generated, so configurable Items 1 or 2 (or both) were the ones causing all this havoc.
How the Final Battle was won, thus ending the war with SCOM
Time to zoom into Items 1 & 2 as stated above. This is what I did:
Time for some experiments. Quickly it turned out the configurable item E-mail Message wasn’t any problem. When I copied the formula from the ‘problematic’ SMTP Channel into the working one, it kept on working. However, when I copied the formula from the E-mail Subject from the ‘problematic’ SMTP Channel into the working one, EventID 4503 was back again!
Let’s crush the ENEMY!
Finally! The item causing the grief was found. But WHY? When I compared the ‘problematic’ SMTP Channel with the working SMTP Channel there was only ONE difference: it contained the header $Data/Context/DataItem/AlertDescription$, which is actually the Description of the Alert as shown in the SCOM R2 Console.
Depending on the Alert the Description might contain some strange characters, or can get as lengthy as a short novel. And strange characters or lengthy subject headers might cause issues with mail messages…
Time for another experiment:
Great! I pinpointed not only the item where it went wrong (the SMTP Channel) but more important, the REAL cause, the header $Data/Context/DataItem/AlertDescription$. Nice!
Time to party!
I imported the export file of the Notifications MP, containing ALL Channels, Subscribers and Subscriptions. Adjusted the Channels based on my findings (removing the header $Data/Context/DataItem/AlertDescription$ in configurable item E-mail subject) and all was well now. All Alerts meeting the Notification criteria were sent out. No more EventID 4503 in the OpsMgr Event log to be found again. Nice!
So whenever you bump into this nagging Event and the earlier mentioned blog postings do not match your case, try this approach by removing the header $Data/Context/DataItem/AlertDescription$ in configurable item E-mail subject of the SMTP Channels and you should be fine again.
And not just that, my customer wanted to document its Notification Model in more detail. Not needed any more since I already had done so while solving this issue! So this customer was happy twice: the Notification Model was fully operational AND thoroughly documented.
Even though it is not that difficult, it is different compared to configuring other MPs. The guide itself is not that detailed about that part so any additional information is welcome.

Thanks Tim for sharing another powerful tool for SCOM. Great job!
My blog is not about virtualization but this one is really special. Already signed myself up for this one or better, three days. It will cost me three evenings (19:00 until 0:00) since I live in another time-zone (GMT+1) but there is much to be learned so it’s worth the investment.
Taken directly from the website of System Center Virtual Machine Manager:

What is a “Jump Start” course?
Also good to know:
‘All sessions are professionally recorded and distributed through MS Showcase, Channel 9, Zune Marketplace and iTunes for broader reach.’
Have had a similar issue before and after having cracked it, the data came back.
Some background information first. This is ‘normal’ behavior because when data is inserted into the Data Warehouse it goes through processes like these:
Basically, when the Perfmon Reports are not showing all data, most of the time the data is present in the Data Warehouse, but is not processed completely. Somewhere it is stuck. By removing the cause of it, the Reports will functioning again. Of course, it takes some time for the data being processed (depending on the total amount of data in the DW), but finally, the Reports end up just fine again.
Let’s get back to this posting now.
Besides the EventID mentioned in the title of this posting, the RMS showed many of these EventID’s as well:
Especially the last EventID contained good additional information: ‘Exception 'SqlException': A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections’.
This MG was already running a long time without any issues. Only an update of the DNS MP had taken place, nothing else. Since the last EventID pointed the finger to the SQL server it was time to check this server out. This is what the System event log of the SQL server showed:
After having talked with the engineers running these servers it turned out that the VMs weren’t configured correctly. The VM for the SQL server ran an iSCSI initiator. But this is not OK. So they changed it in VMware itself to a raw LUN-mapping and assigned it to the VM hosting the SQL Server instance.
Danielle Grandini, a fellow MVP, already blogged about this issue, to be found here.
However, I am not the type of person to modify SPs by hand. So I skipped this option and used another approach: I removed the culprit MP (the Exchange 2010 MP) and afterwards I deleted the whole Dataset (Microsoft.Exchange.2010.Reports.Dataset.Availability) from the Data Warehouse causing all these issues with a certain SP. Got this one from CSS a while back. I will NOT share it.
Afterwards the event log of the RMS turned back to normal again. No more issues. No warnings, no errors. And believe or not, the Reports came back to live again! So all perf data was to be found again. How nice and neat!
I only imported the Exchange 2010 MP and left out the Report MP, hoping the Reporting MP also contains this Data Set and rule. Will see that within a few days I guess. Can’t wait until a new Exchange 2010 MP ships, WITHOUT this issue…
It ended officially yesterday but our group is very fortunate to have two additional days, packed with many sessions. So MVP Summit 2011 for the SCOM MVPs last until Friday the 4th of March. Nice!
Met many new people and learned (and still am learning) tons of new stuff. Exciting days it have been with two more to go.
