Galeracheck is a small, self-contained utility that checks a Galera Cluster Node and returns HTTP codes if the node is up or down. It has been designed primarily for use with HAProxy.
Usage of galeracheck:
-a Available when donor
-c string
MySQL Config file to use (default "~/.my.cnf")
-d Disable when read_only flag is set (desirable when wanting to take a node out of the cluster without desync)
-p int
Port to listen on (default 8000)
