Dynamic Groups and Dependencies
Currently I monitor fifteen data centres at unique customers based in different geographical locations around the world. I have assigned dynamic grouping to them to fit into a predefined group that saves me time sorting my nodes and allows my group alerting and NOC displays to work more efficiently.
Groups are based upon functions of the equipment, location, applications, and dependencies. I have setup groups for my customers nodes meaning they can exist on the same monitoring platform but its easy to see which company they belong to.
I use custom fields mainly for support purposes to allow my engineers to see where the devices fit into the organisation and to provide them with the information they need to effectively support a device.
I use the group information to create a local NOC for each site that I give to the customer inside a custom view for their local technicians and I create a general NOC for engineers who want to see all fifteen locations.
Dependencies are key to the success of your monitoring.
If you have a business critical software application you need to know what servers / hardware it relies upon, these are known as dependencies.
