A good rule is to ensure to keep the number of shards per node below 20 per GB heap.  
How many shards per node is better to have a low overhead in case of fault ?

Logging, log analysis and full text search.  
We have 1000 devices more or less that send logs to elasticsearch.  
We also use kibana to search details about some events and periodically we create a summary report of these events.
