Hi,

I am using foreman to start numerous subsystems such as mongodb,  
elasticsearch, redis and node. With node, I am using the Elasticsearch.js  
client.  
I would like to be able to verify that elasticsearch is ready for use.  
Should I be doing something like a cluster health call like this?

```
        esClient.cluster.health({waitForStatus:'green'}, function(err){
            callback(err)
        })

```

what is the best way to verify that elasticsearch is ready for use and its  
indexes can be accessed?

thanks

Wait for green works. Its a really really common idiom.
