Make sure paths points to the example Apache log file, logstash-tutorial.log, that you downloaded earlier: Open the filebeat.yml file located in your Filebeat installation directory, and replace the contents with the following lines. Step 3 – Configure a filebeat.yml with a some log file $ wget Step 1 – Download your preferred beat. To get started, go here to download the sample data set used in this example. Filebeat has a light resource footprint on the host machine, and the Beats input plugin minimizes the resource demands on the Logstash instance. Filebeat is designed for reliability and low latency. This visualization (aka dashboard) shows the location of the users who have accessed your web site for the time range selected.Filebeat client is a lightweight, resource-friendly tool that collects logs from files on the server and forwards these logs to your Logstash instance for processing. The one below shows website hits over time. There are different nginx dashboards that Filbeat already installed. Now click the Visualize screen, again selecting from the nav bar on the left. The record below is too long to see in its entirety. Kibana will ask you what index pattern you want to use.Ĭlick on a record to expand it. Now, from the Discover screen (i.e., top left button on the nav bar) you can browse records. You can use that when nothing else is in the data itself. KIbana will ask what field it can use as a timestamp.This is so it can produce a time-series analysis, which is the whole point of gathering logs in the first place. Just start typing the letters f-i-l-e and it will show you which ES document indexes match: Of course that won’t be useful if you parse other kinds of logs besides nginx. If you add the date it would read today’s parsed logs. That is, if you put filebeat* it would read all indices that start with the letters filebeat. To add an index pattern simply means how many letters of existing indexes you want to match when you do queries. If you have then navigate to the Management screen and add one. If you have never used Kibana before it will ask you to set up an index pattern. The index name will be some combination of the word filebeat and today’s date. Note that we have saved the userid:password option in the $pwd environment variable. You can verify that by querying ElasticSearch for the indices, replacing the URL below for the URL for you instance of ES. sudo filebeat -eįilebeat will process all of the logs in /var/log/nginx. The -e option will output the logs to stdout. sudo filebeat setup -eįor subsequent runs of Filebeat run it like this. Run this command to push nginx dashboards to Kibana. This makes it simpler to connect to the instance as it eliminates the need to put IP addresses and ports. sudo filebeat modules listĪdd the cloud it and your userid and password to the Filebeat config file. List enabled modules and you will see that nginx is listed. If your web server does not have much data, to get a larger amount of log entries change to the nginx log directly and download these two logs: sudo cd /var/log/nginxĭownload filebeats and then install it: wget If you don’t already have a web server you can install Linux or just download some sample nginx files into the /var/log/nginx folder. Note the cloud ID, password, Kibana URL, and Elasticsearch URL as you will need them below. But here we use Elastic Cloud.įollow the instructions we wrote here to set up ElasticSearch in the cloud if you don’t already have a system. You can use your own locally-installed instance of ElasticSearch. Elastic Cloud account (or set up your own server).nginx web server (or just download the sample shown below and put the into the corresponding folder).(This article is part of our ElasticSearch Guide. We will discuss use cases for when you would want to use Logstash in another post. But that common practice seems redundant here. Note: you could also add ElasticSearch Logstash to this design, but putting that in between FileBeat and Logstash. Using JSON is what gives ElasticSearch the ability to make it easier to query and analyze such logs. We use Filebeat to do that.įilebeat has an nginx module, meaning it is pre-programmed to convert each line of the nginx web server logs to JSON format, which is the format that ElasticSearch requires. Here we explain how to set up ElasticSearch to read nginx web server logs and write them to ElasticSearch.
