Hosts, Sensors and Servers - What's the difference?

A sensor is the core unit of a Wormly test cycle. It specifies a single service to be monitored according to various configurable parameters.

A host is merely a way of grouping sensors together. It tends to represent a server that provides one or more services over TCP/IP, but it is up to users to decide how they use the logical grouping of a host.

The key advantage of grouping sensors within one host is to avoid receiving multiple alerts when a single point of failure takes down all of the related sensors (i.e. because they are hosted on the same physical server).

A server is simply something that you monitor with Wormly sensors. e.g. a web (HTTP) server, SMTP mail server, etc.
