Logstash plays an extremely important role in any ELK-based data pipeline but is still considered as one of the main pain points in the stack. Like any piece of software, Logstash has a lot of nooks and crannies that need to be mastered to be able to log with confidence. How successful you are at running Logstash is directly determined from how well versed you are at working with this file and how skilled you are at debugging issues that may occur if misconfiguring it. Before we take a look at some debugging tactics, you might want to take a deep breath and understand how a Logstash configuration file is built. This might help you avoid unnecessary and really basic mistakes. Each Logstash configuration file contains three sections — input, filter and output. Each section specifies which plugin to use and plugin-specific settings which vary per plugin. You can specify multiple plugins per section, which will be executed in order of appearance. The grok filter plugin is one of the most popular plugins used by Logstash users. Its task is simple — to parse logs into beautiful and easy to analyze data constructs. Handling grok, on the other hand, is the opposite of simple. Still, if you need some tips on grokking, take a look at this article.

This approach reduces noise from excessive logging and helps you focus on the problem area. Add a unique ID to the plugin configuration.

For other versions, see the Versioned plugin docs. For questions about the plugin, open a topic in the Discuss forums. For bugs or feature requests, open an issue in Github. For the list of Elastic supported plugins, please consult the Elastic Support Matrix. This output can be quite convenient when debugging plugin configurations, by allowing instant access to the event data after it has passed through the inputs and filters.

There is no way to route data from a stdout output to log4j2. When you need to debug problems, particularly problems with plugins, consider increasing the logging level to DEBUG to get more verbose messages. I'm having trouble implementing this. Using grep, I am seeing that the value of the field timestamp is not the current date and time. Sample grep'd logs. The improvements added in recent versions, such as the monitoring API and performance improvements, have made it much easier to build resilient and reliable logging pipelines. Logging API. It seems that filebeat is sending the incorrect timestamp value. I don't like that, because then I would have to modify the way it works when i do the -f param, where the logging is happening in a single terminal. If you want to capture stdout of a service then that is a question about whatever service manager you use, not about logstash. For Ruby classes, like LogStash::Outputs::Elasticsearch , the logger name is obtained by lowercasing the full class name and replacing double colons with a single dot. We have an ELK Stack v7. In case an error is detected, you will get a detailed message pointing you to the problem.
