govisor

Govisor is a framework for managing services. It supports dependency graphs of services, and handles starting, stopping, and restarting services as necessary. It also deals with failures, and supports self-healing, and has some advanced logging capabilities. It also offers a REST API for managing your services, as well as a nicer client API, and a snazzy little terminal application to monitor the services.

There is a daemon (govisord) that can be used to manage a tree of process in a manner similar to init or SMF or systemd. However, it is designed to be suitable for use by unprivileged users, and it is possible to run many copies of govisord on the same system (but you will have to choose different TCP management ports.)

Govisord listens by default at http://localhost:8321/

See govisord/main.go for a list of options, etc.

Govisor is designed for embedding as well. You can embed the manager into your own application. The REST API implementation provides a http.Handler, so you can also wrap or embed the API with other web services.

The govisor client application, "govisor", is in the govisor/ directory. It has a number of options, try it with -h to see them.

To install the daemon and client: go get -v github.com/gdamore/govisor/...
