Where the elasticsearch data is stored? - elasticsearch

I've installed filebeat in a server, collecting all the logs from all the containers i have. With filebeat i indicate to which elasticsearch and kibana hosts he must send them (both, elasticsearch and kibana are running as a service in another server). So now all the logs appear in kibana. My question is, all those logs that appear there, are stored somewhere? In elasticsearch or in kibana?
Thank you in advance

All the data is stored inside Elasticsearch.
Kibana is a visualization engine on top of Elasticsearch. Kibana itself also stores its configuration data inside an internal Elasticsearch index called .kibana.
Whatever you can see from Kibana always comes from Elasticsearch.
You can learn more about Elasticsearch here and Kibana here.

How to generate huge random data and populate Elastic search running on K8S cluster?

I've K8S cluster up and running. There is Elastic search and Kibana deployed on the K8S cluster.
I need to populate ES with almost 25 t0 50GB of random data to Elastic search for testing. Any easy way to achieve this. I'm a newbie to ES and K8S. Any inputs or pointers will be of great help.
You can use Logstash for ingesting data to the elasticsearch. Logstash supports various input plugins from elasticsearch log4j to S3. You can try ingesting data from any one of the sources that logstash supports as input plugin.

Can logstash be used to upload data from the file into kibana?

I have this kind of data.
You need to move/index the data to elasticsearch.
You can use filebeat/logstash and migrate the data to elasticsearch.
Once the data migration/indexing is done, then you can connect kibana to elasticsearch.
In the kibana you need to mention the elasticsearch entry.
Once done you could be able to design report/dashboards in kibana.

ELK Docker - Kibana saved objects

Does anyone know if it's possible to provide to kibana dockerized container saved objects (dashboards/ visualizations) during the startup of the container? I didn't notice any specific configuration for this on the elastic.co guides. Are there volumes on the container on which I can copy my .json files
Thanks
Kibana uses an index in Elasticsearch to store saved searches, visualizations and dashboards.
It creates a new index if the index doesn’t already exist.
kibana.index: ".kibana"

How to Analyze logs from multiple sources in ELK

I have started working on ELK recently and have a doubt regarding handling of multiple types of logs.
I have two sets of logs on my server that I want to analyse, one from my android application and the other from my website. I have successfully transferred logs from this server via filebeat to the ELK server.
I have created two filters for either types of logs and have successfully imported these logs into logstash and then Kibana.
This link helped do the above stuff.
https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elk-stack-on-centos-7
The above link directs to use the logs in the filebeat index in Kibana and start analysing(I successfully did for one type of logs). But the problem that I am facing is that since both these logs are very different, they need to be analysed differently. How do I do this in Kibana. Should I create multiple filebeat indexes there and import them, or should it be just one single index, or some other way. I am not very clear on this(could not find much documentation), hence would request to please help and guide me here.
Elasticsearch organizes by index and type. Elastic used to compare these to SQL concepts, but now offers a new explanation.
Since you say that the logs are very different, Elastic is saying that you should use different indexes.
In Kibana, the visualization is tied to an index. If you had one panel from each index, you can show them both on the same dashboard.

Kibana: store and load Kibana index from another Elasticsearch server?

Hihi everyone
In the configuration file of Kibana, "config.js" we can only configure elasticsearch address and the name of the kibana index, i would like to be able to configure another ES adress for the the kibana index.
So i could store and load kibana dashboard from/to another ES server that the one i'm requesting data.
Could anyone please help ;) thanks
