A bare-bones dead node notification system for Consul
Here's a basic watch script that will look through the output for serfHealth checks in
the critical state. The serfHealth check is a built-in check added by Consul that keeps
track of the health of a node. When this watch handler fires, it will get the JSON body of
the health endpoint passed
to it over stdin.
#!/bin/sh
for node in $(jq '.[] | select(.CheckID=="serfHealth" and .Status=="critical") | .Node' -); do
echo "$node is dead"
