I was searching for ES performance by google and I find some documents.
They says modify ES config is good for ES performance.
So, I edit my ES config like below.
*/etc/elasticsearch/elasticsearch.yml*
index.number_of_replica: 0
index.number_of_shards: 3
index.translog.flush_threshold_ops: 50000
index.refresh_interval: -1
indices.memory.index_buffer_size: 50%
index.store.type: mmapfs
bootstrap.mlockall: true
*/etc/default/elasticsearch*
ES_HEAP_SIZE: 4g (my machine has 8g RAM)
MAX_LOCKED_MEMORY=unlimited
After configure above restart ES and LS.
*# /etc/init.d/elasticsearch restart && sudo restart logstash*
And make sure ES setting is correctly using curl command.
*# curl 'localhost:9200/logstash-iis-test04/_settings?pretty'*
{
"logstash-iis-test04" : {
"settings" : {
"index" : {
"creation_date" : "1426555104697",
"uuid" : "0PuOIGj-RnKS9cMKXbsryQ",
"number_of_replicas" : "0",
"number_of_shards" : "3",
"refresh_interval" : "5s",
"version" : {
"created" : "1010199"
}
}
}
}
}
As you see, index.number_of_replicas and index.number_of_shards values is
correct
but , index.refresh_interval is not correct (I set this value is -1)
and another setting is not shown, where can I find another settings?
I want to see settings like index.translog.flush_threshold_ops,
index.refresh_interval, indices.memory.index_buffer_size, index.store.type,
bootstrap.mlockall..
and want to know this settings is correctly applied.
Maybe you know why this result is shown, please advice to me.
Regards
