Hi all,
Until recently, I was working as a software architect in embedded systems. In my company, the software applications are generally distributed over several machines. There is a common need to supervise these applications and to provide utilities to start/stop them dynamically. It was quite obvious that Supervisor could help. However, it only deals with a single machine and the solutions that are referenced on the Supervisor web site ( http://supervisord.org/plugins.html#dashboards-and- tools-for-multiple-supervisor-instances) don’t really help to maintain the status and the integrity of a distributed application. So I have implemented for my company a C++ solution dealing with multiple Supervisor instances, but mostly centered on the applications rather than on the machines. A few months ago, I have decided to start an open-source Python project based on the same principles (and learn the Python language at the same time). “Supervisors” can be used as a Supervisor plugin, using the supervisor configuration file. The project can be found here: https://github.com/julien6387/supervisors. It comes with the following additional functions: * extended XML-RPC API, * extended supervisorctl, * new HTTP interface including basic statistics about processes and machines, * Python and JAVA clients for XML-RPC API and event subscription. The documentation is available in the supervisors/doc directory of the installation. Supervisors still requires a lot of formal testing and there are some functions not implemented yet. However, it should already do most of the job. The documentation and the HTTP interface have been written with a CSS compliant only with a recent firefox and is currently not readable with other browsers, sorry. Your comments are most welcome. Regards, Julien Le Cléach.
