This is a rare but interesting scenario… which can cause you to see and monitor duplicate objects (and get duplicate alerts) for specific types of discovered hosted objects that have a parent class which was upgraded from one version to another. For instance – if you upgrade SQL 2005 >…
Here is an interesting little concept of how to use OpsMgr. Because I have a lab, that is exposed to the internet over port 3389, I get a LOT of hacking attempts on this lab. Mostly the source is from bots running on other compromised systems. These bots just do…
Something I wrote to get a report on tasks being run on the OpsDB, and their output: select tv.Name as TaskName, bme.fullname as ObjectName, jsv.SubmittedBy, jsv.TimeStarted, jsv.TimeFinished, jsv.Output, tv.Description as TaskDescriptionfrom JobStatusView jsvinner join TaskView tv on jsv.MonitoringTaskId = tv.Idinner join BaseManagedEntity bme on jsv.TargetMonitoringObjectId = bme.BaseManagedEntityIdorder by TimeStarted DESC…
Do you ever get script errors from a discovery scripts? Or you aren’t discovering something that you feel should be discovered? There are many ways to troubleshoot this discovery process, this will cover the “basics”. First thing I like to do – is start with the console. 1. …
You may notice that there are actions you might want to take on an agent, that are grayed out and not available in the console. There actions might include: Change Primary Management Server Repair Uninstall See the below image for an example: This is caused by a flag in…
The Microsoft SQL Server management packs for 2005 and 2008 will discover and monitor SQL 2005 Express edition and the Windows Internal Database by default. This is often not desired, and causes a lot of noise in the management group, because these are not full blown instances of SQL, and…
You will likely find that the default retention in the SCOM data warehouse will need to be adjusted for your environment. I often find customers are reluctant to adjust these – because they don’t know what they want to keep. So they assume the defaults are good, and they just…
This is something I see in almost all clients when we perform a SCOM RAAS (Health Check). The customer will have lots of data being inserted into the OpsDB from agents, about monitors that are constantly changing state. This can have a very negative effect on overall performance of the…
We often think of tuning OpsMgr by way of tuning “Alert Noise”…. by disabling rules that generate alerts that we don’t care about, or modifying thresholds on monitors to make the alert more actionable for our specific environment. However – one area of OpsMgr that often goes overlooked, is event…
This is something a LOT of people make mistakes on – so I wanted to write a post on the correct way to do this properly, using a very common target as an example. When we write a monitor for something like “Processor\% Processor Time\_Total” and target “Windows Server Operating…
