I have ELK all this three components configured on my local windows machine up and running.
I have a logfile on a remote centos7 machine available which I want to ship from there to my local windows with the help of Filebeat. How I can achieve that?
I have installed filebeat on centos with the help of rpm.
in configuration file I have made following changes
commented output.elasticsearch
and uncommented output.logstash (which Ip of my windows machine shall I give overe here? How to get that ip)
AND
**filebeat.inputs:
type: log
enabled: true
paths:
path to my log file**
The flow of the data is:
Agent => logstash > elasticsearch
Agent could be beat family, and you are using filebeat that is okay.
You have to configure all these stuff.
on filebeat you have to configure filebeat.yml
on logstash you have to configure logstash.conf
on elasticsearch you have to configure elasticsearch.yml
I personally will start with logstash.conf
input
{
beats
{
port =>5044
}
}
filter
{
#I assume you just want the log to run into elasticsearch
}
output
{
elasticsearch
{
hosts => "(YOUR_ELASTICSEARCH_IP):9200"
index=>"insertindexname"
}
stdout
{
codec => rubydebug
}
}
this is a very minimal working configuration. this means, Logstash will listen for input from filebeat in port 5044. Filter is needed when you want parse the data. Output is where you want to store the data. We are using elasticsearch output plugin since you want to store it to elasticsearch. stdout is super helpful for debugging your configuration file. add this you will regret nothing. This will print all the messages that sent to elasticsearch
filebeat.yml
filebeat.inputs:
- type: log
paths:
- /directory/of/your/file/file.log
output.logstash:
hosts: ["YOUR_LOGSTASH_IP:5044"]
this is a very minimal working filebeat.yml. paths is where you want logstash to harvest the file.
When you done configuring the file, start elasticsearch then logstash then filebeat.
Let me know any difficulties

I've been working to install ELK stack in CloudFoundry and sending log files from other local server by using filebeat.
I have successfully installed ELK in CloudFoundry and able to see sample messages.
Now I am trying to send log files from local server by using filebeat. Can you suggest how to configure filebeat to send log files from local server to Logstash in CloudFoundry?
You'll need to configure the Logstash output in Filebeat for this, specifying the host & port for target logstash:
#----------------------------- Logstash output --------------------------------
output.logstash:
hosts: ["127.0.0.1:5044"]
On the logstash side, you'll need to add a beats input to the config:
input {
beats {
port => 5044
}
}
output {
elasticsearch {
hosts => ["http://localhost:9200"]
index => "%{[#metadata][beat]}-%{[#metadata][version]}"
}
}

I am assigned with task to create a central logging server. In my case there are many web app servers spread across. My task is to get logs from these different servers and manage in central server where there will be elastic-search and kibana.
Question
Is it possible to get logs from servers that are having different public IP? If possible how?
How much resource (CPU, Memory, Storage) is required in central server.
Things seen
Saw the examples setups where all logs and applications are on same machine only.
Looking for way to send logs over public IP to elastic-search.
I would like to differ from the Ishara's Answer. You can ship logs directly from filebeat to elasticsearch without using logstash, If your logs are generic types(system logs, nginx logs, apache logs), Using this approach You don't need to go into incur extra cost and maintenance of logstash as filebeat provides inbuilt parsing processor.
If you have debian based OS on your server, I have prepared a shell script to install and configure filebeat. You need to change elasticsearch server URL and modify second last line based on the modules that you want to configure.
Regarding your first question, Yes, You can run filebeat agent on each server and send data to centralize Elasticsearch.
For your second question, It depends on the amount of logs elasticsearch server is going to process and store. It also depends on the where kibana is hosted.

Yes, it is possible to get logs from servers that are having different public IP. You need to setup an agent like filebeat (provided by elastic) to each server which produce logs.
You need to setup filebeat instance in each machine.
It will listen to your log files in each machine and forward them to the logstash instance you would mention in filebeat.yml configuration file like below:
#=========================== Filebeat inputs =============================
filebeat.inputs:
- type: log
# Change to true to enable this input configuration.
enabled: true
# Paths that should be crawled and fetched. Glob based paths.
paths:
- /path_to_your_log_1/ELK/your_log1.log
- /path_to_your_log_2/ELK/your_log2.log
#----------------------------- Logstash output --------------------------------
output.logstash:
# The Logstash hosts
hosts: ["private_ip_of_logstash_server:5044"]
Logstash server listens to port 5044 and stream all logs through logstash configuration files:
input {
beats { port => 5044 }
}
filter {
# your log filtering logic is here
}
output {
elasticsearch {
hosts => [ "elasticcsearch_server_private_ip:9200" ]
index => "your_idex_name"
}
}
In logstash you can filter and split your logs into fields and send them to elasticsearch.
Resources depend on how much of data you produce, data retention plan, TPS and your custom requirements. If you can provide some more details, I would be able to provide a rough idea about resource requirement.
We are setting up elasticsearch, kibana, logstash and filebeat on a server to analyse log files from many applications. Due to reasons* each application log file ends up in a separate directory on the ELK server. We have about 20 log files.
As I understand we can run a logstash pipeline config file for each
application log file. That will be one logstash instance running
with 20 pipelines in parallel and each pipeline will need its own
beat port. Please confirm that this is correct?
Can we have one filebeat instance running or do we need one for each
pipeline/logfile?
Is this architecture ok or do you see any major down sides?
Thank you!
*There are different vendors responsible for different applications and they run a cross many different OS and many of them will not or can't install anything like filebeats.
We do not recommend reading log files from network volumes. Whenever
possible, install Filebeat on the host machine and send the log files
directly from there. Reading files from network volumes (especially on
Windows) can have unexpected side effects. For example, changed file
identifiers may result in Filebeat reading a log file from scratch
again.
Reference
We always recommend installing Filebeat on the remote servers. Using
shared folders is not supported. The typical setup is that you have a
Logstash + Elasticsearch + Kibana in a central place (one or multiple
servers) and Filebeat installed on the remote machines from where you
are collecting data.
Reference
For one filebeat instance running you can apply different configuration settings to different files by defining multiple input sections as below example, check here for more
filebeat.inputs:
- type: log
enabled: true
paths:
- 'C:\App01_Logs\log.txt'
tags: ["App01"]
fields:
app_name: App01
- type: log
enabled: true
paths:
- 'C:\App02_Logs\log.txt'
tags: ["App02"]
fields:
app_name: App02
- type: log
enabled: true
paths:
- 'C:\App03_Logs\log.txt'
tags: ["App03"]
fields:
app_name: App03
And you can have one logstash pipeline with if statement in filter
filter {
if [fields][app_name] == "App01" {
grok { }
} else if [fields][app_name] == "App02" {
grok { }
} else {
grok { }
}
}
Condtion can be also if "App02" in [tags] or if [source]=="C:\App01_Logs\log.txt" as we send from filebeat
Hi I've been working on a automated logging using elastic stack. I have filebeat that is reading logs from the path and output is set to logstash over the port 5044. The logstash config has an input listening to 5044 and output pushing to localhost:9200. The issue is I can't get it to work, I have no idea what's happening. Below are the files:
My filebeat.yml path: etc/filebeat/filebeat.yml
#=========================== Filebeat prospectors =============================
filebeat.prospectors:
# Each - is a prospector. Most options can be set at the prospector level, so
# you can use different prospectors for various configurations.
# Below are the prospector specific configurations.

Please Note: Elasticsearch, logstash, filebeat are all installed on the same machine with ip: 10.10.XX.XX and I've checked the firewall, it's not the issue for sure.
I checked that logstash, filebeat services are all running. Filebeat is able to push the data to elasticsearch when configured so and logstash is able to push the data to elasticsearch when configured so.
Maybe it's how I am executing the process is the issue..
I do a bin/logstash -f logpipeline30aug.config in /usr/share/logstash to start it and then I do a /etc/init.d/filebeat start from the root directory.
Please Note: Formatting may be effected due to stackoverflow formatting issue
Can someone please help? I've been trying everything since 3 days now, I've gone through the documentations as well
Your filebeat.yml looks invalid.
The output section lacks an indentation:
output.logstash:
hosts: ["10.10.XX.XX:5044"]
In general, check the correctness of the config files to ensure they're ok.
For instance, for filebeat, you can run:
filebeat -c /etc/filebeat/filebeat.yml -configtest
If you have any errors it explains what is that error so you can fix it.
You can use a similar approach for other ELK services as well
I 'm newbie in ELK and and I'm getting issues while running logstash. I ran logstash as define in structure step by step as I do for file beat but
But when run filebeat and logstash, Its show logstash successfully runs at port 9600. In filebeat it gives like this
INFO No non-zero metrics in the last 30s
Logstash is not getting input from file beat. Please help.
My problem is as the same as this article and did what it said but noting change .
the filebeat.yml is :
filebeat.prospectors:
- input_type: log
paths:
- /usr/share/tomcat/log_app/news/*.log
output.logstash:
hosts: ["10.0.20.163:5000"]
and I ran this command sudo ./filebeat -e -c filebeat.yml -d "publish"
the logstash config file is :
input {
beats {
port => "5000"
}
}
filter {
grok {
match => { "message" => "%{COMBINEDAPACHELOG}"}
}
geoip {
source => "clientip"
}
}
output {
elasticsearch {
hosts => [ "localhost:9200" ]
index => "%{[#metadata][beat]}-%{+YYYY.MM.dd}"
document_type => "%{[#metadata][type]}"
}
}
then ran the commands
1)bin/logstash -f first-pipeline.conf --config.test_and_exit - this gave Ok
2)bin/logstash -f first-pipeline.conf --config.reload.automatic -This started the logstash on port 9600
I couldn't proceeds after this since filebeat gives the INFO
INFO No non-zero metrics in the last 30s
and I use
elastic search : 5.5.1
kibana : 5.5.1
logstash : 5.5.1
file beat : 5.5.1
If you want to resend your data, you can try to delete filebeat's registry file, and when you restart filebeat, it will send the data again.
File location depends on your platform. See https://www.elastic.co/guide/en/beats/filebeat/5.3/migration-registry-file.html
Registry file location can also be defined in your filebeat.yml:
filebeat.registry_file: registry
https://www.elastic.co/guide/en/beats/filebeat/current/configuration-global-options.html
Everytime you stop the filebeat. It will start reading the data from the tail of file. And because the sample file which you are using are not getting frequent data. It's not able to fetch and send it to elastic search.
Edit your log file. Add few more redundant data and then try it. It should work.
This error which you have mentioned is because FIlebeat is not able to get any updated data in that file.
