Logstash creating pipelines from Kafka not working - elasticsearch

I am trying to get data from Kafka topic to run into ELK-stack with Logstash but can't get the data moving.
I edited the logstash.conf to following:
input {
tcp {
port => 5000
}
kafka {
bootstrap_servers => "broker:29092"
topics => ["PLACES_ROWKEY"]
}
}
## Add your filters / logstash plugins configuration here
output {
elasticsearch {
hosts => ["elasticsearch:9200"]
user => "elastic"
password => "changeme"
index => "from_logstash"
}
}
Im running this setup in Docker if it matters (broker is the hostname for the Kafka broker container). I restart the Logstash but cant see any new indices in elasticsearch

How to push logs from kubernetes to elastic cloud deployment?

I am trying to configure logstash and filebeat running in kubernetes to connect and push logs from kubernetes cluster to my deployment in the elastic cloud.
I have configured the logstash.yaml file with host, username and password, please find the config below:
apiVersion: v1
kind: ConfigMap
metadata:
name: logstash-config
namespace: ns-elastic
data:
logstash.conf: |-
input {
beats {
port => "9600"
}
}
filter {
fingerprint {
source => "message"
target => "[#metadata][fingerprint]"
method => "MURMUR3"
}
# Container logs are received with variable named index_prefix
# Since it is in json format, we can decode it via json filter plugin.
if [index_prefix] == "store-logs" {
if [message] =~ /^\{.*\}$/ {
json {
source => "message"
skip_on_invalid_json => true
}
}
}
if [index_prefix] == "ingress-" {
if [message] =~ /^\{.*\}$/ {
json {
source => "message"
skip_on_invalid_json => true
}
}
}
# do not expose index_prefix field to kibana
mutate {
# #metadata is not exposed outside of Logstash by default.
add_field => { "[#metadata][index_prefix]" => "%{index_prefix}-%{+YYYY.MM.dd}" }
# since we added index_prefix to metadata, we no longer need ["index_prefix"] field.
remove_field => ["index_prefix"]
}
}
output {
# You can uncomment this line to investigate the generated events by the logstash.
stdout { codec => rubydebug }
elasticsearch {
hosts => "https://******.es.*****.azure.elastic-cloud.com:9243"
user => "username"
password => "*****************"
document_id => "%{[#metadata][fingerprint]}"
# The events will be stored in elasticsearch under previously defined index_prefix value.
index => "%{[#metadata][index_prefix]}"
}
}
However, the logstash restarts with the below error:
[2022-06-19T17:32:31,943][INFO ][org.logstash.beats.Server][main][3cdfe6dec21f50e50e275d7a0c7a3d34d8ead0610c72e80ef9c735c2ef53beb9] Starting server on port: 9600

Can anyone please help me understand what I am doing incorrectly here? My endgoal is to push logs from my kubernetes cluster to my deployment of elasticsearch service on Elastic Cloud. Please assist as I am unable to get enough resources on this.
The error we see in your logs says:
Error: Address already in use
Exception: Java::JavaNet::BindException
This means there is already a process that binds on port TCP/9600.
You could use netstat -plant to inspect services listening on your host. Could be another instance of logstash that was not properly shut down.

Got response code '400' contacting Elasticsearch at URL in logstash

I am new to elasticsearch. I tried to configure elastisearch, Kibana , logstash with MQTT plugin. I supposed to send logs to elasticseach through logstash MQTT plugin. I installed them on Mac locally, but when starting logstash, it throws following error.
[2021-11-12T17:26:37,976][ERROR][logstash.outputs.elasticsearch][logstash_pipeline] Unable to get license information {:url=>"http://localhost:9200/", :exception=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::BadResponseCodeError, :message=>"Got response code '400' contacting Elasticsearch at URL 'http://localhost:9200/_license'"}
my logstash configuration file islike:
input {
mqtt {
host => "localhost"
port => 1883
topic => "test"
qos => 0
certificate_path => "/Users/john/logstash-7.10.2/logstash/m2mqtt_ca.crt"
}
}
output {
elasticsearch {
hosts => ["http://localhost:9200"]
index => "%{[#metadata][beat]}-%{[#metadata][version]}-%{+YYYY.MM.dd}"
#user => "elastic"
#password => "changeme"
}
}
can anybody tell, what was the issue?

Consume messages from rabbitmq in logstash

Im trying to read logs from rabbitmq queue from logstash and then pass it to elasticsearch. But with no success. Here is my logstash config.
input {
rabbitmq {
host => "localhost"
port => 15672
heartbeat => 30
durable => true
exchange => "logging_queue"
exchange_type => "logging_queue"
}
}
output {
elasticsearch {
hosts => "localhost:9200"
}
stdout {}
}
But there is no index created so ofcourse I cant see any logs in Kibana
There are some messages in queue
I think the correct (default) port is 5672, as 15672 is the port of the web admin console.
input {
rabbitmq {
host => "localhost"
port => 5672 <--- change this
heartbeat => 30
durable => true
exchange => "logging_queue"
exchange_type => "logging_queue"
}
}
output {
elasticsearch {
hosts => "localhost:9200"
}
stdout {}
}

Where does logstash /elasticsearch write data?

In my input section of my logstash config file, I have created a configuration for reading a rabbitMQ queue. Using the RabbitMQ console, I can see logstash drain the queue. However, I have no idea what logstash is doing with the message. Is it discarding it? Is if forwarding it to elasticsearch?
Here's the logstash configuration
input {
rabbitmq {
host => "192.168.34.151"
exchange => an_exchange
key => a_key
queue => a_queue
}
}
output {
elasticsearch {
embedded => true
protocol => http
}
}
edit - removed the bogus comma from the config.

Unable to load index to elasticsearch using logstash

I'm Unable to load index to elasticsearch using logstash. The follwing are my logstash.conf settings. To me config settings seems fine. Please help if I'm missing something.
Assume that Logstash & elastic search services are running fine.
input {
file {
type => "IISLog"
path => "C:/inetpub/logs/LogFiles/W3SVC1/u_ex140930.log"
start_postition => "beginning"
}
}
output {
stdout { debug => true debug_format => "ruby"}
elasticsearch_http {
host => "localhost"
port => 9200
protocol => "http"
index => "iislogs2"
}
}
You can start with checking the following:
Check the logstash log file for errors.
Run the following command:telnet localhost 9200 and verify you are able to connect.
Check elasticsearch log files for errors.
