Within a minute or two, you should see a new Logstash index in Elasticsearch… curl -X GET "localhost:9200/_cat/indices?v" We can now start the pipeline with: sudo service logstash start In this file, we will use the beats input plugin, a number of filter plugins to process the data including the geoip filter plugin for adding geographic data to the logs, and the Elasticsearch output plugin: input

Sudo apt-get install logstash: sudo vim /etc/logstash/conf.d/nf Java should already be installed if you’re running Tomcat, so simply run: sudo apt-get install logstash
Our next part of the pipeline is Logstash. Hosts: Installing and configuring Logstash var/log/tomcat8/localhost_access_log.*.txt Next, configure Filebeat to collect the Tomcat access log file and forward it to Logstash for processing: sudo vim /etc/filebeat/filebeat.yml

To install Filebeat, use: sudo apt-get update Then, save the repository definition: echo "deb stable main" | sudo tee -a Installing and configuring Filebeatįirst, and if you haven’t already, download and install the Elastic signing key: wget -qO - | sudo If you have multiple Tomcat servers, however, a better method would be to use Filebeat as a collector on each host, and a single Logstash instance for aggregating the logs, processing them and forwarding them into Elasticsearch. You could use Logstash as the collector, processor and forwarder. There are a number of ways you could ship the Tomcat access logs to the ELK Stack.
Sudo apt-get install tomcat8-docs tomcat8-examples tomcat8-adminĪs a side note, OpenJDK will be installed as a dependency when you install the tomcat8 package which will also help us when installing Logstash. Note, we’re also installing tomcat8-docs, tomcat8-examples, and tomcat8-admin which provide web apps with docs, tests, and admin features for Tomcat. If you haven’t, below are instructions for installing the server on an Ubuntu 16.04 machine. If you’ve already got Tomcat installed, great. These contain important information on the requests served by Tomcat, including the IP address of the client sending the request, the request method and URL path, the HTTP status code, the number of bytes returned to the client and more. Access log – records HTTP transactions between the client and the application serverĪs explained above, in this article we will focus on one specific type - access logs.Catalina.out – uncaught exceptions and thread dumps.Catalina log – records information about events such as the startup and shutdown of the Tomcat application server.Tomcat provides a number of log types that can be used for monitoring Tomcat performance and the requests it serves: To follow the steps outlined here, you’ll need your own ELK Stack or a Logz.io account.

In this article, we’ll show how to collect, process and analyze these logs using the ELK Stack and Logz.io.
But just like Apache and Nginx, Tomcat serves requests and as such provides access logs for monitoring traffic. Tomcat is not a web server like Apache or Nginx but is defined as a Java servlet container, or a web container that provides extended functionality for interacting with Java Servlets. It consumes a relatively small amount of resources and provides users with simpler admin features. Tomcat is particularly popular for serving smaller applications since it doesn’t require the full Java EE platform.
