A brief video showing the features of the alerts summary page.
The alert summary page can be a very useful tool for getting a high-level picture of the health of your network. When you first navigate to this page you might be greeted with a single bar like the one you see here.
Any time you see things rolled up like you see here, they can be broken out in greater detail just by selecting them. We went from a device group at the top down to individual devices. I can take it a step further by selecting individual devices.
Before I scroll too far, I'd like to go over some of the settings you can apply to help give you some context. I'm actually going to say, "I want to see all alerts from today that have affected my Cisco gear." Change the time-span if I want it, but I'm going to leave that be for the moment and now we see only Cisco gear.
In the advance settings I could limit the severities I see. Another common, advanced feature is to say, "Hey, I only want to see devices that are in trouble. If everything's all green, I don't need that stealing focus." So, you deselect "include results without alerts" and what we'll do is break this out to second-tier, showing the devices in the device group automatically without me having to click. I hit preview and we'll see just that. The cool thing with these color changes is you can actually click on them and go to the alert archive. Alternatively, I can break out the device by components.
Now I have a bunch of interfaces that are tied to this individual device. I can select any item here that was in violation and I have a few options. I can go to the alert archives because this is not going to be an active alert from the system. It's been archived. It has a clear start and end time. What I'm going to do is select the object summary and use our predefined template. I can actually investigate a little bit deeper in terms of what exactly occurred on this component, in this case an interface of that device simply by clicking the color-changed bar within the alert summary page here.
You can tear some of this stuff off, pdf, csv, much like in other parts of the product.
In addition to these videos, remember that the Data Appliance NMS User Manual is available through the NMS UI as shown below. Clicking on the question mark at the top right of any page will automatically bring you to the section of the manual that corresponds to the page you are currently on.
