SCOM – New “Friday Rules” Series…Let’s Rule!

image

Today I would like to announce “Friday Rules”. Yes, of course Friday rules, but in my context I am going to publish short videos about the monitoring rules in SCOM always on a Friday. My goal is to show a short example (10-15 minutes) how you can create rules and what those can do for you. At the end of this series, I will have covered all rules in SCOM. It is sometimes very basic stuff, but I think it is still valuable for some of those who are new to SCOM and want to explore it.

SCOM 2012 – Performance View “Rotate Chart” Selected, How To Get Back

If you are in the SCOM console and you choose a performance view, you are able to select “Rotate Chart”….

…this will give you a kind of 3D view of your chart. Well, yes it does something, and you can do something with it, but in my opinion it is useless. Because you can move your mouse and rotate / flip the chart around forever and you will not find a setting that will satisfy. The absolute great thing is, you won’t be able to return to normal view by deselecting this option again. You will be caught in this view…

How can you return?

SCOM 2012 – SNMP Traps, How The Heck Do I Get It Working?

In this post I would like to share some know-how and my personal experience, because I have seen it so many times in the forums and other blogs which had trouble getting SNMP Traps working in SCOM 2012.

The difference between SCOM 2007 R2 and SCOM 2012 (R2) in terms of network monitoring is, that Microsoft rebuilt their SNMP stack for monitoring SNMP devices. Some advantages are, that we got sexy dashboards available with a lot of performance and availability data, a broad range of network device vendor support, a new RunAs account type for the community string to support SNMP V1, V2 and V3 credentials and so on. In addition to the features mentioned, Microsoft integrated a SNMP trap receiver right into SCOM and right there the confusion starts. I would like to show what it takes to get SNMP traps up and running.

SCOM 2012 – VSAE Extend Unix Class For Dynamic Grouping

Some time ago I wrote a post where I extended a Linux class for dynamic grouping using the Visual Studio Authoring Extensions (VSAE). Well, this was just for playing around and testing some stuff. Recently I had a requirement to build views according to Unix teams. There were different Unix / Linux distributions, all kind of server names and in addition I needed to group the servers according to patch classes, service level and team. So there is no way of using any of the standard attributes of the computer or more specific classes. What we need is a way to add additional information to the Unix computer class, in a similar way as extending the Windows computer class with attributes from registry values.

Because the Unix computers are managed by different teams than SCOM, I needed a way to let the SCOM team manage information of grouping the computers and building the views etc. according to defined parameters in the CMDB.

I decided to rebuild the MP I had started previously and bring it to a level which would fit the requirements.

The idea is to upload a configuration text file into the directory /etc/microsoft via SCOM task. The configuration file is located in a defined file share location and can be uniquely identified by its FQDN name e.g. linux00.bigfirm.com-SCOMConfig.txt. This file should contain the data in one line separated by semicolon “;” like PatchClassA;SLA1;CompanyXZ;TeamC; …

  • PatchClass = When the system gets patched like group A,B,C,D…
  • SLA = What service level does this system belong to 1,2,3,4….
  • Company = To which company does this system belong to XY, ABC…
  • Team = Which team is responsible for it A,B,C,D…

System Center Universe Europe 2014 – Get Into Gear Now!

image

System Center Universe is an community conference that is focused on systems management and virtualization topics such as Microsoft System Center, Microsoft Hyper-V, Microsoft Windows Server and Client Operating Systems and Windows Azure. Last year the event was called System Center Universe DACH and after great success it has been renamed to System Center Universe Europe. But the credo and focus is still the same “top quality from the community to the community” and besides that only few things have changed to take this conference to the next level. As you can imagine, a session is always as good as its speakers. Therefore it is obvious, that there participate some of the best speakers and community leaders from around the world, who will present high quality sessions at the conference.

Mark these dates in your calendar now:

September 17th-19th 2014, Congress Center Basel, Switzerland 

If you never heard of System Center Universe Europe before, I urge you to check out the website immediately at http://www.systemcenteruniverse.ch/ where you are also able to register right away.

Quick Post – SCOM Script Monitor Customizing Alert Name

This time I needed to build a two-state script monitor to test several file shares for availability. The script works in multiple steps…

  1. Try to access the shared folder
  2. Create a file within the share
  3. Check if the file exists
  4. Delete the file

If one of the tests above would fail, we need to get an alert. Well, this is actually not that hard to create and don’t worry I am not going to publish another VBScript. What is more interesting is to create a meaningful alert. It makes sense to have the file share name in the alert name e.g. “Failed to access share \\server01\temp”. But how are we going to achieve this?

Quick Post – SCOM An account specified in the Run As profile Microsoft.SystemCenter.Omonline.OutsideIn.RunAsProfile…

During a recent install of SCOM the health state of 4 management servers turned suddenly to critical and the 2 others stayed healthy. The setup consists of totally 6 management servers split up into 3 Resource Pools (Windows, Unix/Linux, Network/SNMP) and several gateway servers. It was somewhat suspicious, because for a long time the management group stayed healthy and didn’t have any issues. The alert I received looked like this…

The interesting part is here…

….

Management Group:
Run As Profile: Microsoft.SystemCenter.Omonline.OutsideIn.RunAsProfile.Configuration
Account SSID: 007EFD0C5AC560C1B24DF51301135E7F0C415DC48B0000000000000000
0000000000000000000000

….

This alert tells us, that there must be a Run As Profile which contains a Run As Account that is not distributed to all Health Services, in this case the 4 unhealthy management servers. We get here a pretty go hint as we see the SSID of the account, but not how can find out which Run As account is hiding behind this long number?
