In fact logic is simple..
We must establish AND (IT components that are critical to tree) and
OR (IT
components that are not critical to tree such as one of the many app
servers..) operations on IT components to construct a tree..
When we setup customer systems, we always try to create a check which
is "end-to-end" to simulate an actual user.
For instance, if they provide an online web account facility, we
create a plugin that logs in to their web site with a known user name
and known password, and check that the balance is what is expected.
This proves the "business process" is working.
What happens underneath is irrelevant. There could be 3 app servers
that are down out of the 5. There could be a DB switch over to the
backup node. There could be disk failures on hundreds of hosts. It
doesn't matter - those get displayed in the hostgroup hierarchy for
investigation.
But the user perspective check stays relevant because this is what the
user is seeing. This is what should be reported on.
NBP seems to be trying to put that information into all the
components. So take these 12 services and if 10 are ok, then the
business process is okay. It just seems like another layer of
configuration.
I think the simulation is a clever idea, but that's born out of
necessity of the complex logic required to determine if the overall
state of a business process is okay.
Maybe you have a business process that is hard to simulate in a
regular service check?
