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 have installed ELK in one server and filebeat in other server where logs resides. My logs are moved and able to view in Kibana. But I dont need the commented lines and lines with certains text to be displayed in kibana. Hence I used drop_event and exclude_lines in Filebeat and I even used drop filter in logstash but I dont see them refelecting in Kibana dashboard. Can anyone help on this.
I am really new to the ELK stack, any help will be appreciated.
The idea was to have:
rsyslog server -> redis -> ELK stack
by following this recipe: https://sematext.com/blog/recipe-rsyslog-redis-logstash/
I can see the traffic go all the way to Elasticsearch, but have not been able to debug Elasticsearch yet. I believe that traffic should be going there because tcpdump shows it.
If I go to "Stack monitoring", Logstash is not showing up there. When going deeper, it does say that the "Logstash node has been detected", and nothing more.
The issue was that Kibana is not automatically showing logs in the Observability/Stream.
On the top of the page there is a link to settings where you should choose
log index pattern that you have created.
A little unintuitive considering having that massive screaming button to add integrations.
Is there a possibility to push the analysis report taken from the Performance Center to Logstash and visualize them in Kibana? I just wanted to automate the task of checking each vuser log file and then push errors to ELK stack. How can I retrieve the files by script and automate this. I can't get any direction on this because I need to automate the task of automatically reading from each vuser_log file.
Filebeat should be your tool to get done what you mentioned.
To automatically read entries you write in a file (could be a log file) you simply need a shipper tool which can be Filebeat (It integrates well with ELK stack. Logstash can also do the same thing though but that's heavy and requires JVM )
To do this in ELK stack you need following :
Filebeat should be setup on "all" instances where your main application is running- and generating logs.
Filebeat is simple lightweight shipper tool that can read your logs entries and then send them to Logstash.
Setup one instance of Logstash (that's L of ELK) which will receive events from Filebeat. Logstash will send data to Elastic Search
Setup one instance of Elastic Search (that's E of ELK) where your data will be stored
Setup one instance of Kibana (that's K of ELK). Kibana is the front end tool to view and interact with Elastic search via Rest calls
Refer following link for setting up above mentioned:

I have been planning to use ELK for our production environment and seems to be running into a weird problem -
the problem is that while loading a sample of the production log file I realized that there is a huge mismatch in the number of events being published by Filebeat and what we see in kibana. My first doubt was on filebeat but i could verify that all the events were successfully received in logstash.
I also checked logstash (by enabling debug mode ) and could see all the events were received and processed (i am using the following filters date , json ) and i could see them getting processed successfully
but when i do a search in kibana I only get to see the percent of the number of logs being actually published (e.g. only 16000 out of 350K). No exception or error in either logstash or elasticsearch logs.
I have tried zapping the entire data by doing the following so far :
Stopped all processes for ES, Logstash and kibana.
Deleted all the index files, cleared the cache , deleted mappings
stopped filebeat, deleted registry files (since its running in windows)
Restarted elasticsearch, logstash and filebeat (in that order)
but same results. i get only 2 out of 8 records (in the shortened file) and even less when i use the full file
i tried increasing the time windows in kibana to 10 years (:)) to see if they are being pushed to the wrong year but got nothing
I have read almost all threads related to the missing data but nothing seems to work.
any pointers would help !
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.

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.
