I have logstash installed in a server which will process logs and publish to elastic search. But, is it possible for logstash to pull logs from remote servers (linux) without installing filebeats in those servers.
Or if filebeats can be installed in the same server as logstash and can it fetch the logs? Please help me if there is any other option as well.
Thanks in advance
Neither Logstash nor Filebeat can pull/fetch log files from remote servers, you need to have some tool installed in the remote servers that will ship the logs elsewhere.
Logstash can consume logs from message queue systems like kafka, redis or rabbitmq, for example, but you need that your remote servers send the logs to those systems anyway, so you would need a log shipper on your remote servers.

When using logstash to retrieve airflow logs from a folder you have access to, would I still need to make any changes in the airflow.cfg file?
For instance, I have airflow and ELK deployed on same ec2 instance. The logstash .conf file has access to the airflow logs path since they are on the same instance. Do I need to turn on remote logging in airflow config?
In fact you have two options to push airflow logs to Elastic Search:
Using a log collector (logstash, fluentd, ...) to collect Airflow log then send it to Elastic Search server, in this case you don't need to change any Airflow config, you can just read the logs from the files or stdout and send it to ES.
Using Airflow remote logging feature, in this case Airflow will log directly to your remote logging server (ES in your case), and will store a local version of this log to show it when the remote server is unavailable.
So the answer to your question is no, if you have a logstash, you don't need Airflow remote logging config
So I am new to this, i installed the elk and FORTIGATE but don't know how to transfer the logs over IP..
thank you
i searched over internet but not able to find any correct way.
Try to enable syslog to logstash: here
And use fortigate filters for logstash.
I am new to Elasticsearch and logstash. I wanted to know if there's a way to get windows event logs of remote systems which login to my server(which has logstash) where the windows systems don't have any logpusher software on them.
Thanks in Advance!
How can I stream logs from multiple log4net in elasticsearch??
For example, if I have multiple Windows servers with .net apps and log4net running on each server, each server streaming logs on a separate UDP port. How do I setup logs on elasticsearch server to index logs from multiple ports ?
You can use logstash connectors for this purpose. Look at this :
Using logstash, ElasticSearch and log4net for centralized logging in Windows
Can packetbeat is used to monitor the tomcat server logs and windows logs?? or it will only monitor the database i.e., network monitoring?
Packetbeat only does network monitoring. But you can use it together with Logstash or Logstash-Forwarder to get visibility also into your logs.
It will do only network monitoring. you can use ELK for tomcat server logs.
#tsg is correct but now with the Beats 1.x release they are deprecating Logstash Forwarder in lieu of another Beat called Filebeat. Also they added Topbeat, which allows you to monitor server load and processes in your cluster.
See:
* https://www.elastic.co/blog/beats-1-0-0
You will likely want to install the package repo for your OS, then install each with:
{package manager cmd} install packetbeat
{package manager cmd} install topbeat
{package manager cmd} install filebeat
They each are installed in common directories. For example with Ubuntu (Linux) the config files are in /etc/<beat name>/<beat name>.yml where beat name is one of the 3 above. Each file are similar and you can disable the direct ES export and instead export to Logstash (comment ES and uncomment Logstash) and then add a beats import in your Logstash config. From thereon, Logstash listens for any beats over that port and can redistribute (or queue) using the [#metadata][beat] param to tell where it came from.
Libbeat also provides a framework to build your own so you can send any data you want to Logstash and it can queue and/or index. ;-)
Packetbeat is used mainly for network analysis . It currently supports following protocols :
ICMP (v4 and v6)
DNS
HTTP
Mysql
PostgreSQL
Redis
Thrift-RPC
MongoDB
Memcache
However , for visualizing tomcat logs you can configure them to use log4j and then configure logstash to take input from log4j and then using elasticsearch and kibana to visualise the logs.
To monitor windows logs you can use another beats platform Winlogbeat.
