I have an issue here, I installed the plugin "richardwilly98/elasticsearch-river-mongodb".
To work with this,
I created an entry in mongodb
Then i created a index with river.
Usually now an index must be created with the elasticsearch.
But its not creating any index other than river, and nothing is shown in console rather than elasticsearch is started.
Can someone shed some light to find a solution to this problem?
Thanks

If we need to create queries in Kibana dashboard without creating any codebase change where can we do it. Is there any place to create queries in Kibana. Please tell me anyone who knows that place. Because I have a big problem in our project, creating a dashboard for the logs.
see either https://www.elastic.co/guide/en/kibana/current/kuery-query.html or https://www.elastic.co/guide/en/kibana/current/lucene-query.html
and https://www.elastic.co/guide/en/kibana/current/save-load-delete-query.html may also be relevant
I have managed to process log files using the ELK kit and I can now see my logs on Kibana.
I have scoured the internet and can't seem to find a way to remove all the old logs, viewable in Kibana, from months ago. (Well an explaination that I understand). I just want to clear my Kibana and start a fresh by loading new logs and them being the only ones displayed. Does anyone know how I would do that?
Note: Even if I remove all the Index Patterns (in Management section), the processed logs are still there.
Context: I have been looking at using ELK to analyse testing logs in my work. For that reason, I am using ElasticSearch, Kibana and Logstatsh v5.4, and I am unable to download a newer version due to company restrictions.
Any help would be much appreciated!

Update:
I've typed "GET /_cat/indices/*?v&s=index" into the Dev Tools>Console and got a list of indices.
I initially used the "DELETE" function, and it didn't appear to be working. However, after restarting everything, it worked the seond time and I was able to remove all the existing indices which subsiquently removed all logs being displayed in Kibana.
SUCCESS!
Kibana is just the visualization part of the elastic stack, your data is stored in elasticsearch, to get rid of it you need to delete your index.
The 5.4 version is very old and already passed the EOL date, it does not have any UI to delete the index, you will need to use the elasticsearch REST API to delete it.
You can do it from kibana, just click in Dev Tools, first you will need to list your index using the cat indices endpoint.
GET "/_cat/indices?v&s=index&pretty"
After that you will need to use the delete api endpoint to delete your index.
DELETE /name-of-your-index
On the newer versions you can do it using the Index Management UI, you should try to talk with your company to get the new version.
I'm new to elasticsearch and am still trying to set it up. I have installed elasticsearch 5.5.1 using default values I have also installed Kibana 5.5.1 using the default values. I've also installed the ingest-attachment plugin with the latest x-pack plugin. I have elasticsearch running as a service and I have Kibana open in my browser. On the Kibana dashboardI have an error stating that it is unable to fetch mappings. I guess this is because I havn't set up any indices or pipelines yet. This is where I need some steer, all the documentation I've found so far on-line isn't particularly clear. I have a directory with a mixture of document types such as pdf and doc files. My ultimate goal is to be able to search these documents with values that a user will enter via an app. I'm guessing I need to use the Dev Tools/console window in Kibana using the 'PUT' command to create a pipeline next, but I'm unsure of how I should do this so that it points to my directory with the documents. Can anybody provide me an example of this for this version please.
If I understand you correctly, let's first set some basic understanding about elasticsearch:
Elasticsearch in it's simple definition is a "Search engine". so you need to store some data, and then elastic will help you to search using a search criteria, and it will retrieve relevant data back
You need a "Container" to save your data to, and elastic has this thing like any database engine to store your data, but the terms are somehow different. for example a "Database" in sql-like systems is called "Index", and what you know as "table" is called "Type" in elastic.
from my understanding, you will need to create your index (with or without mappings) to have a starting point, and I recommend you to start without mappings just to "start" and get things working, but later on it's highly recommend to work with "mappings" if applicable, because elastic is smart, but it cannot know more about your data than you do
Because Kibana has failed to find a proper index to start with, it has complained and asked you to either provide a syntax for index names, or a specific index name so it can infer the inline mappings and give you the nice features of querying, displaying charts, etc of your data, so once you create your index, you will provide that to the starting page of Kibana, and you will be ready to go.
Let me know if you need something more specific to your needs :)
I have created some index in Elasticsearch with mapper attachment plugin. However, when I try to create index in Kibana, I could not find back any data created in Elasticsearch for making dashboard in Kibana
Is there any way to resolve this issue?
Try running http://:9200/_cat/indices?v
The above will return all indexes you have. Once you verified that your mapper attachment index is there, go to Kibana at Settings tab and select the checkbox that say your index do not contain time series data. Now write your index name and I hope you find it. Also, make sure your Kibana is configured to point to the Elasticsearch server your index resides. This is configured in the config/kibana.yaml.
Hope I have managed to help!
I am a newbie in elasticsearch, please forgive me if my question sounds weird :D
I want to index files in some directories with elasticsearch automatically (for example: if i add a file in certain directory then elasticsearch can index that file immediately), but i don't know how to configure elasticsearch in order to solve that problem.
Can anyone suggest me?
Thank in advance
I dont think you can have elasticsearch watch a directory (I wouldn't think that is a good thing to do in most cases.)
Instead, have a client wrapper that implements a FileWatcher. Push changes to ElasticSearch via this client.
You could use PathHierarchyTokenizer to preserve the file system hierarchy in your index, allowing you to drill down your Directory structure.
