![]() ![]() First, while the ELK Stack leveraged the open source community to grow into the most popular centralized logging platform in the world, Elastic decided to close source Elasticsearch and Kibana in early 2021. A few things to note about ELKīefore we get started, it’s important to note two things about the ELK Stack today. The next part will focus on analysis and visualization. This first part will explain the basic steps of installing the different components of the stack and establishing pipelines of logs from your containers. We will be writing a series of articles describing how to get started with logging a Dockerized environment with ELK. ![]() ![]() While it is not always easy and straightforward to set up an ELK pipeline (the difficulty is determined by your environment specifications), the end result can look like this Kibana monitoring dashboard for Docker logs: The ELK Stack (Elasticsearch, Logstash and Kibana) is one way to overcome some, if not all, of these hurdles. Transiency, distribution, isolation - all of the prime reasons that we opt to use containers for running our applications are also the causes of huge headaches when attempting to build an effective centralized logging solution. ![]() That’s why there are so many HTTP error 400s (bad request) on this server.The irony one faces when trying to log Docker containers is that the very same reason we chose to use them in our architecture in the first place is also the biggest challenge. One observation you can make here as this web server, as any public web server, is constantly being hit by hackers looking to see what vulnerabilities you have left exposed. Here is the world map showing where your traffic comes from: Now you will see charts on the dashboard. Then type the letters nginx to find the dashboard: For now, we’ll use the dashboards that nginx has created, although you can make your own dashboards for specific use cases. So, start Filebeat like this: sudo service filebeat start Open the Kibana nginx Dashboard Loading dashboards (Kibana must be running and reachable)Īfter a while it will stop, once it has installed the dashboards. Now run this command to push the filebeat dashboards to Kibana: sudo filebeat setup -dashboards Assuming you are using the regular nginx layout, just enable the nginx module. There is no configuration necessary, unless you have modified the log location in nginx, in which case you would need to put the paths in /etc/filebeat/modules.d/nginx.yml. You don’t need to install Filebeat in a container as the installation is simple and requires no configuration. Now open the console: address):5601/app/kibana#/home Install Filebeat Nohup docker run -link(container id):elasticsearch -p 5601:5601 kibana:7.6.2& Instead, I leave off security, set my firewall rules to allow access only from my designated IP address, and I follow these instructions.) sudo -i If you don’t turn on security, people running port scans against your service will find your Kibana install and be able to use it without logging in. Instead, you’ll need to turn on security, which I don’t cover in this article. ( Important note: To put Kibana on a public IP address, do not follow these steps. Otherwise Kibana will bind to localhost, which does no good since you can’t reach it across the network. Then pass a routable IP address to Kibana using the SERVER_HOST environment variable. Run this command to get the container ID: sudo docker ps Then you need the docker container ID to install and start Kibana. We use Docker since it’s the simplest way to install Kibana.įirst, install ElasticSearch: sudo docker pull /elasticsearch/elasticsearch:7.6.2 Filebeat is one of several Elasticsearch data shippers others are Logstash, Metricbeat, and Packetbeat, plus a couple of specialized ones. Kibana is the graphical front-end for Elasticsearch. We will use the nginx Filebeat module and, of course, Elasticsearch. In this article, I’ll show how to use Kibana to monitor the nginx web server.
