I’m trying to implement a good way to check the status of a cluster (on all nodes). I’d rather not connect to each node for their status because I need it every second. This is necessary for monitoring, alarms, and autoscaling.
I’d like implement exactly what Galera suggests but I don’t know how to do this per Manticore instance: https://galeracluster.com/library/documentation/notification-cmd.html. Specifically I can’t figure out how to set the wsrep_notify_cmd setting for Galera.
What is the best way to set/get all node status’ in one place?
