I'm not sure how to deduce the optimum "index.translog.flush\_  
threshold\_ops" for my Logstash setup.  
Logstash indexes are created on daily basis. I'd like some advises. I hope  
these helps:

i. ES version- 0.90.0 stable  
ii. ES index template  
curl -XPUT [http://localhost:9200/\_template/loggerstash](http://localhost:9200/_template/loggerstash)[http://10.0.4.24:9200/\_template/loggerstash](http://10.0.4.24:9200/_template/loggerstash)-d '  
{

```
"template" : 

```

"logstash\*",  
"settings" : { "number\_of\_shards" : 1,  
"index.cache.field.type" : "soft",  
"index.refresh\_interval" : "10s",  
"index.store.compress.stored" : true }  
}'  
iii. Logstash pushes approx. 2800 logs/sec into ES.  
iv. ES is tuned with  
ES\_HEAP\_SIZE=3g  
MAX\_LOCKED\_MEMORY=unlimited  
MAX\_OPEN\_FILES=65535  
bootstrap.mlockall= true

Do I need further change other parameters mentioned here[http://www.elasticsearch.org/guide/reference/index-modules/translog/](http://www.elasticsearch.org/guide/reference/index-modules/translog/)other than the default?

Thanks,
