Restart server on node failure with Consul - microservices

Question

Newbie to Microservices here.
I have been looking into develop a microservice with spring actuator while having Consul for service discovery and fail recovery.
I have configured a cluster as explained in Consul documentation.
Now what I'm trying to do is configure a Consul Watch to trigger when any of my service is down and execute a shell script to restart my service. Following is my configuration file.
{
"bind_addr": "127.0.0.1",
"datacenter": "dc1",
"encrypt": "EXz7LsrhpQ4idwqffiFoQ==",
"data_dir": "/data",
"log_level": "INFO",
"enable_syslog": true,
"enable_debug": true,
"enable_script_checks": true,
"ui":true,
"node_name": "SpringConsulClient",
"server": false,
"service": { "name": "Apache", "tags": ["HTTP"], "port": 8080,
"check": {"script": "curl localhost >/dev/null 2>&1", "interval": "10s"}},
"rejoin_after_leave": true,
"watches": [
{
"type": "service",
"handler": "/Consul-Script.sh"
}
]
}
Any help/tip would be greatly appreciate.

Take a closer look at the description of the service watch type in the official documentation. It has an example, how you can specify it:
{
"type": "service",
"service": "redis",
"args": ["/usr/bin/my-service-handler.sh", "-redis"]
}
Note that it has no property handler and but takes a path to the script as an argument. And one more:
It requires the "service" parameter
It seems, in you case you need to specify it as follows:
"watches": [
{
"type": "service",
"service": "Apache",
"args": ["/fully/qualified/path/to/Consul-Script.sh"]
}
]
