Vagus is daemon that can exchange alive-information from instances so clients can get an overview of what is alive. It is meant to scale to at least 50 hosts.
It supports:
- IPv4 and IPv6
- UDP unicast
- UDP broadcast
- UDP multicast
- Multiple namespaces/clusters
It is not a full-fledged HA system. It merely provides a mechanism for building a HA system.
Tested on:
- Python 2.7.6, 2.7.12
- Linux 3.11.10, 4.4.57, 4.4.62
It will not work on Windows because it needs to discover network interfaces and addresses using the getifaddrs() system call.
Vagus comes with an install script that installs it as a system service running under systemd.
- clone the respository
- with root priviliges run
install.sh
Done. Vagus has now been installed into /usr/local/vagus, and it is already running.
It has a non-mandatory read-only web interface running on port 8724.
It was built for use in https://github.com/privacore/open-source-search-engine
The name Vagus comes from the vagus nerve which partially controls the human heart.
