Click on “Manage extractors” and then on the “Get started” button once the new “Add extractor” window opens up.Ĭlick on “Load Message” and on the “message” field choose your extractor from the “Select extractor type” menu. It’s time to go back and add a couple of extractors to solve this issue. If you click on the “Show Received Messages” button, you will see that, even if the data is all here, the messages you received are completely unformatted so the data is all mashed up. Note also how there are two different port numbers ports based upon that configuration file we set up before. This way we can filter them out in different message streams when I need to parse them later on. One is a static field from Nginx, and the other one is going to be the error_log and access_log respectively. Now, we need to add a few tags to the input. We’re also going to change the port to some different port that we have. We’ll make it a global node titled “Nginx error_log” since we created an access_log already. Just click on “Launch a new input” to create it. Once you modified the configuration, it’s time to create a new input – a Syslog UDP in this case. Copy-paste all these lines and modify your Nginx configuration.

You can scroll through all the details of the readme until you find what you’re looking for at the very bottom – the configuration. The first stepsĪt first, we're going to go off and find a JSON knowledge pack in the marketplace – in this case, we're going to use one from Nginx. In a nutshell, the JSON format is a great tool for parsing logs by turning unstructured data into structured data.

You can parse useful info from various sources such as the destination addresses, the different sources, and response bytes.

The JSON format is full of interesting data that, if extracted, can create a nice and accessible format because of its layout. Using JSON extractors to switch to structured logging

We will briefly teach you how to set them up, correctly configure them, and do some parsing. In this Graylog tech series video we're going to learn how to extract valuable data from JSON responses using JSON extractors.
