Listing service info

A really nice feature of Hydra is that each application running hydra emits health and presence information. That information can be inspected by any application using hydra.

The hydra-cli program is really just a command-line client running Hydra — which is what powers most of its capabilities.

We can view a list of nodes using the nodes command:

$ hydra-cli nodes

Many hydra-powered apps export API routes. We can view a list of service routes using:

$ hydra-cli routes

You can retrieve the health status of your services using the health command.

$ hydra-cli health

If you specify a service name then you’ll only see the health information for that service.

$ hydra-cli health myservice
