unable to send logs to ec2 logstash - amazon-ec2

I can not log data trhough AWS EC2 logstash instance to AWS ES, while I do can log data with docker logstash service using same logstash.conf configuration file to AWS ES
Security group for EC2 logstash instance:
logstash.conf
input {
udp {
port => 8089
codec => json
}
elasticsearch {
...
}
}
...
running logstash:
....
[INFO ] xxxxxxxxxxxxxxxx [[main]<udp] udp - Starting UDP listener {:address=>"0.0.0.0:8089"}
[INFO ] xxxxxxxxxxxxxxxx [[main]<udp] udp - UDP listener started {:address=>"0.0.0.0:8089", :receive_buffer_bytes=>"106496", :queue_size=>"2000"}
[INFO ] xxxxxxxxxxxxxxxx [Api Webserver] agent - Successfully started Logstash API endpoint {:port=>9600}
But running the logstash service with docker-compose.yml logs are sent to AWS ES. Below logstash service configuration from docker-compose.yml
logstash:

Logstash pipeline not showing on Kibana, but logs show Pipelines running

Trying to set up elastic search, kibana and logstash to read logs from local folder.
It works well on version 7.x.x, but when I try to upgrade to 8 it doesn't.Fx
I am using this YAML file:
version: '3.6'

and config for logstash:
input {
file {
path => "/test/Logs/test.slog"
start_position => "beginning"
}
}
output {
elasticsearch {
hosts => ["elasticsearch:9200"]
}
}
test.slog exist and contain logs.
the logstash docker show the following logs:

But when I go to the Data -> Index Management there is nothing. and also in the Ingest pipeline.
What am I doing wrong?
In Elasticsearch 8 the index names created by logstash output follow the pattern .ds-logs-generic-default-%{+yyyy.MM.dd} instead of logstash-%{+yyyy.MM.dd}
This .ds index does not appear under Data -> Index Management but the documents can be queried
You can view the .ds-logs-generic index in Kibana, Management> Dev Tools using
GET _cat/indices
To query the documents you can use the _search API
GET /.ds-logs-generic-default-2022.08.28-000001/_search
{
"query": {
"match_all": {}
}
}
If you want to specify the index name you can add it to the output section of your logstash.conf eg index => "logstash-%{+YYYY.MM.dd}"
output {
elasticsearch {
hosts => ["elasticsearch:9200"]
index => "logstash-%{+YYYY.MM.dd}"
}
}
The newly created index will show in Kibana under Management > Data > Index Management. You may need to add a few log lines at the end of your logfile to kick the indexing pipeline.

Services empty in Opensearch Trace Analytics

I'm using Amazon OpenSearch with the engine OpenSearch 1.2.
I was working on setting up APM with the following details
Service 1 - Tomcat Application running on an EC2 server that accesses an RDS database. The server is behind a load balancer with a sub-domain mapped to it.
I added a file - setenv.sh file in the tomcat/bin folder with the following content

The data-prepper is getting authenticated via Fine access based control with all_access role and I'm able to see the otel resources like indexes, index templates generated when running it.
On running the above setup, I'm able to see traces from the application in the Trace Analytics Dashboard of OpenSearch, and upon clicking on the individual traces, I'm able to see a pie chart with one service. I also don't see any errors in the otel-collector as well as in data-prepper. Also, in the logs of data prepper, I see records being sent to otel service map.
However, the services tab of Trace Analytics remains empty and the otel service map index also remains empty.
I have been unable to figure out the reason behind this even after going through the documentation and any help is appreciated!

Kibana 7.7.0 Basic version: management tab missing Security panel when started from docker

Context: I want to use XPACK in order to control which user can see which Dasboard only with free version.
I downloaded Kibana 7.7.0 zip from here, installed it and I can see Security options to create users/roles. In fact, I created an index, an user and a role and successfully set the index to this role with this installed Elastic/Kibana in my Windows.
The issue happeans only with Elastic/Kibana started from docker. I started Kibana 7.7.0 from a docker and I can't see Security panel under Management page. Googling I found I must use Basic version Instead of Open Source. As far as I can see, the docker-compose bellow is downloading Basic version since there isn't "sso" at the end. Also I must use installers provided by Elastic instad of Apache. Well, as far as I see it is pulling image not related to Apache.
I am not sure if the issue is only with Kibana since I could enable xpack security on Elastic and run elasticsearch-setup-passwords interactive inside the elastic docker container. I can log ing in Kibana with Elastic user but I don't see Security tab under Management.
Also, I am getting issue from LogStash trying to connect to ElasticSearch even though I set the logstash_system (see logstash.conf bellow).
You can see that I have enabled xpack.security.enabled=true on ElasticSearch.

In case it is worth to mention, LogStash is failling to connect to ElasticSearch with this log and, as you can see from logstash.conf I set up logstash_system (the user created from elasticsearch-setup-passwords interactive)

So, my straight question is: am I missing some extra configuration in order to enable Security on Kibana? Surrounding questions are: is Kibana/Elastic from docker not the same from zip file? Am I missing some extra configurationin order to allow Logstash to connect to ElasticSearch

Take a note it is failling with ""Got response code '401' contacting Elasticsearch at URL 'http://elasticsearch:9200/_xpack'" error. I guess that in my particular docker setups it demands to be the Docker Machine IP which in my case is 192.168.99.100. Is there someway to replace elasticsearch by this IP?

logstash sincedb file not created with docker-compose

I have a logstash instance running with docker-compose on an AWS EC2 (AMI) instance. I have mounted a folder as volume to the container. I have logstash pipeline config to write the sincedb file in the mounted folder. The pipeline runs but it doesn't write anything for the sincedb file.
The same configuration works on my local machine, but not on EC2. I have checked that the user has rights to write in the folder by creating a file there (eg: vi test).
Docker compose config:
version: "2"
services:
logstash:

I've fixed this. Had to explicitly add user:root in the docker-compose service config.

Filebeat is not creating index in Elasticsearch

I'm setting up Filebeat to send logs to Elasticsearch. This is my filebeat.yml:
filebeat.prospectors:
- type: log
paths:
- '/var/log/project/*.log'
json.message_key: message
output.elasticsearch:
hosts: ["localhost:9200"]
I have this file /var/log/project/test.log with this content:
{ "message": "This is a test" }
and I was expecting this log to be sent to Elasticsearch. Elasticsearch is running in a Docker container in localhost at 9200.
When I run filebeat (Docker), no index is created in Elasticsearch. So, in Kibana, I don't see any data.
Why is that? Isn't supposed that Filebeat creates index automatically?
Solved! I wasn't sharing logs dir between host and Filebeat container, so there wasn't logs to send.
I added a volume when run Filebeat:
docker run -it -v $(pwd)/filebeat.yml:/usr/share/filebeat/filebeat.yml -v /var/log/project/:/var/log/project/ docker.elastic.co/beats/filebeat:6.4.0
you can create index as below
output.elasticsearch:
hosts: ["localhost:9200"]
index: "test-%{+yyyy.MM.dd}"
