Learn how to override a management pack in System Center Operations Manager. If you want to make a change to a management pack, such as a threshold for a monitor, you can do this by overriding the default pack and saving it as a new one.
- [Narrator] In a previous video, we imported a management pack for system center operations manager. As you see in the right hand side, most of these management packs are sealed, and what that means is that it can not be changed. Now there are scripts and there are third party applications that can be used to override and change a sealed management pack to an unsealed management pack, but let's just stay with what's supported at this time and learn how to override a sealed management pack in Operations Manager.
Microsoft seals the management packs in order so no changes can be made to the base management pack, but you can always go in and make changes to a new management pack or create what we call an override. To get to an override, we need to switch over to our Monitoring area, and then we can go ahead and choose an active alert. We see all these different alerts that are going on, and we can go ahead and choose Override from the list, and we have some options.
We can disable the monitor, so that way they don't see this particular error anymore, and you have lots of different options here. You can do it for just the object that we've highlighted, or for all objects of this class, so that would be any type of severity here. We could also do it for a group. We could do it for a specific object of class, or we could go to all of the objects of another class where a new box will pop up and show all the different classes. Our other option, when we go back to Overrides is to Override the Monitor, and it gives us these same exact options.
We're going to choose just this specific option here where it just shows this particular active alert, and we'll click that top option, and we'll get a new box that pops up. Now here's all the different things in the management pack that tell what this active alert should do when it reaches a certain threshold. If we check the Alert On State, we can see the Alert On State description, which is the new custom override will be created in the blank. Click Apply to view the new effective value for this parameter.
What this basically means is that if we choose a specific management pack, such as the Client Monitoring Override, then it changes that blank to the client monitoring override management pack, and it's going to Alert On State, and we can change the different values that you see here at the top to say whether or not we wanted to Alert On State or not. We can also choose to enforce it no matter what. It's always going to be alerted, so nothing can override this particular override.
Let's go ahead and scroll back, uncheck the Alert On State, and just choose the Enabled. The Enabled is a simple yes or no, is this alert enabled? From here we can choose the False option if we want, and we can say the Override Value is False. We can say the Effective Value is False. We can say the Default Value is False, whatever it is we want to say, and we can choose to disable this by checking the Enabled button and changing it to two False. We can also again choose to enforce or not.
The Show Monitor Properties gives us the actual management pack properties from this particular client monitoring management pack. From here we can see the various different tabs that we have here, and we also have the Override option. We can choose the Override option from here, and again, we can choose it for the object, for all objects, for a group, et cetera. It brings up basically the exact same box that we were looking at. It just opens up again in a redundant fashion.
We don't need to actually show the monitor properties here. We can just edit this particular one, and we can say that we no longer want to have it enabled, or we can go ahead and uncheck and then just go ahead and cancel out. Let's choose one of the other options in the Override, and this time we're going to choose the for all objects of another class. This brings up the box that shows all of the other classes, not just the one that we were highlighting.
From here we can choose to make changes to any one of those classes. These are all based on the management packs that are pre-installed or that we have added manually, such as we've shown in a previous video. You go ahead and double-click on a particular class, and the exact same options once again appear. Why would we want to override an alert or a management pack? Well, it maybe because we have an alert that is just annoying.
We just don't need to see that alert anymore. We know it's a problem, and we've decided that we just don't want it to show up anymore. It could also be that it is an outdated alert that is no longer important as a general class type of alert. There could be many different reasons why we no longer want to see an alert the way it was presented to us in the sealed management pack. By overriding default settings for a management pack, it helps us customize our system center operation manager monitoring and allows us to choose specific thresholds in our monitoring procedures.
