Hi

In the article linked below, I saw that for a daily rollover of indexes and around 5 shards per index my cluster will be hurting after around 6 months unless I have around 15 ES nodes.

Here is the quote:

> "If you roll with the defaults for Logstash (daily indices) and ES (5 shards), you could generate up to 890 shards in 6 months. Further, your cluster will be hurting—unless you have 15 nodes or more."

Is this true?

I have a lot of logs entering the ES and heavy logstash calculations, and the ES is lagging in discover and graphs etc.. How can I check if the number of nodes is the reason (I have 6 nodes)?

Many thanks,

I am not sure which article you are regering to as I do not see any link.

How many indices are you creating per day? How large are the shards of these indices? Are all your 6 nodes data nodes? What is their specification?

Hi,

I now edited in the article and quoted the important part.

I have the default rollover of filebeat 1 per day. Amount of shards is also by default 5 shards per node. 2 of the nodes are master and the rest are data. What do you mean "What is their specification?"? Also, I can get to around 15K jsons input per second.

Thanks for the quick reply.

Have a look at [this blog post around shards and sharding](https://www.elastic.co/blog/how-many-shards-should-i-have-in-my-elasticsearch-cluster). The article you linked to seem to primarily discuss search use cases where time based indices are not used, and may therefore not be applicable.
