I am doing centralized logging using logstash. I am using logstash-forwarder on the shipper node and ELK stack on the collector node.I wanted to know the location where the logs are stored in elasticsearch i didn't see any data files created where the logs are stored.Do anyone has idea about this?
Login to the server that runs Elasticsearch
If it's an ubuntu box, open the /etc/elasticsearch/elasticsearch.yml
Check out the path.data configuration
The files are stored on that location
Good luck.
I agree with #Tomer but the default path to logs in case of ubuntu is
/var/log/elasticsearch.log
/var/log/elasticsearch-access.log
/var/log/elasticsearch_deprecation.log
In /etc/elasticsearch/elasticsearch.yml the path to data path is commented out by default.
So the default path to logs is /var/log/elasticsearch/elasticsearch.log
As others have pointed out, path.data will be where Elasticsearch stores its data (in your case indexed logs) and path.logs is where Elasticsearch stores its own logs.
If you can't find elasticsearch.yml, you can have a look at the command line, where you'll find something like -Des.path.conf=/opt/elasticsearch/config
If path.data/path.logs aren't set, they should be under a data/logs directory under path.home. In my case, the command line shows -Des.path.home=/opt/elasticsearch

The problem is that Filebeats is sending duplicated logs to Elasticsearch, when I restart Filebeats, he sends the whole log again.
I have been mounting /var/share/filebeat/data to the container where I am runnig Filebeats. I also had change the permissions of the share directory, to be owned by the filebeats user.
I am using Elasticsearch 8.1.2
The most probable reason for this is persistent volume location for filebeat registry. Essentially, filebeat creates a registry to keep track of all log files processed and to what offset. If this registry is not stored on a persistent location (for instance stored to /tmp) and filebeat is restarted, the registry file will be lost and new one will be created. This tells filebeat to tail all the log files present at specified path from beginning, hence the duplicate logs.
To resolve this, please mount a persistent volume to filebeat (may be hostpath) and configure it to be used for storing registry.
Thanks for the answers, but the issue was that in the initial setup we didn't define an ID tag for the filestream input type. As simple as that.

I am trying to integrate hadoop with ELK stack.
My use case is " i have to get a data from a file present in HDFS path and show the contents on kibana dashboard"
Hive is not working there so I can't use hive.
Are there any other ways to do that?
Anybody is having any article with step by step process?
I have tried to get logs from a linux location on a hadoop server through logstash and filebeat but that is also not working.
I'm doing this for some OSINT work it is quite easy to do once one can get the content out of hdfs into a local filesystem. That's done by setting up a HdfsNfsGateway. Once that's done use filebeat and logstash to import your content into elasticsearch. After that just configure your kibana dashboard for the index your using.
I'm new to the ELK stack so I'm not sure what the problem is. I have a configuration file (see screenshot, it's based on the elasticsearch tutorial):
Configuration File
Logstash is able to read the logs (it says Pipeline main started) but when the configuration file is run, elasticsearch doesn't react. I can search through the files
However, when I open Kibana, it says no results found. I checked and made sure that my range is the full day.
Any help would be appreciated!
I previously used Filebeat to load log data to the Elasticsearch though logstash, then I would like to try it again. So I reinstalled the Filebeat and emptied the Elasticsearch data, and then tried to reload the log data by Filebeat to Elasticsearch. But the Filebeat already knows that the data has been loaded once eventhough the Elasticsearch data storage is emptied. How Filebeat knows that log data was previously loaded? and if I would like to load again all log data, what should I do?
You need to clear the registry_file so that the "history" of read files is cleared as well.
To change the default configuration for the registry_file you just need to specify the full configuration path in the config file (filebeat.yml): https://www.elastic.co/guide/en/beats/filebeat/current/configuration-filebeat-options.html#_registry_file
For example:
filebeat:
registry_file: /var/lib/filebeat/registry
So I have this Elasticsearch installation, in insert data with logstash, visualize them with kibana.
Everything in the conf file is commented, so it's using the default folders which are relative to the elastic search folder.
1/ I store data with logstash
2/ I look at them with kibana
3/ I close the instance of elastic seach, kibana and logstash
4/ I DELETE their folders
5/ I re-extract everything and reconfigure them
6/ I go into kibana and the data are still there
How is this possible?
This command will however delete the data : curl -XDELETE 'http://127.0.0.1:9200/_all'
Thanks.
ps : forgot to say that I'm on windows
If you've installed ES on Linux, the default data folder is in /var/lib/elasticsearch (CentOS) or /var/lib/elasticsearch/data (Ubuntu)
If you're on Windows or if you've simply extracted ES from the ZIP/TGZ file, then you should have a data sub-folder in the extraction folder.
Have a look into the Nodes Stats and try
http://127.0.0.1:9200/_nodes/stats/fs?pretty
On Windows 10 with ElasticSearch 7 it shows:
"path" : "C:\\ProgramData\\Elastic\\Elasticsearch\\data\\nodes\\0"
According to the documentation the data is stored in a folder called "data" in the elastic search root directory.
If you run the Windows MSI installer (at least for 5.5.x), the default location for data files is:
C:\ProgramData\Elastic\Elasticsearch\data
The config and logs directories are siblings of data.
Elastic search is storing data under the folder 'Data' as mentioned above answers.
Is there any other elastic search instance available on your local network?
If yes, please check the cluster name. If you use same cluster name in the same network it will share data.
Refer this link for more info.
On centos:
/var/lib/elasticsearch
It should be in your extracted elasticsearch. Something like es/data
