This guide will help you understand how to integrate Graylog with your system. Graylog is an open-source log management solution that allows you to aggregate, analyze, and visualize log data.

Prerequisites

  • Graylog server installed and running
  • Access to the Graylog server's web interface
  • Basic knowledge of Linux and log management

Steps for Integration

  1. Configure the Source: In Graylog, you need to configure a source to collect logs from your system. This can be done by adding a new input in the Graylog web interface.

    • Navigate to the "Inputs" section in the Graylog web interface.
    • Click on "Add Input" and select the appropriate input type for your source (e.g., Filebeat, Journalbeat, Syslog, etc.).
    • Configure the input settings as per your requirement.

  2. Set Up a Pipeline: Once the source is configured, you need to set up a pipeline to process the logs.

    • Navigate to the "Pipelines" section in the Graylog web interface.
    • Click on "Add Pipeline" and select the appropriate pipeline type for your use case.
    • Configure the pipeline rules to process the logs as needed.

  3. Create a Search: After setting up the pipeline, you can create a search to query and analyze the logs.

    • Navigate to the "Search" section in the Graylog web interface.
    • Enter your search query to filter the logs.
    • Use the available filters and visualizations to analyze the logs.

  4. Visualize the Data: Graylog provides various visualization options to help you understand the log data.

    • Use the "Graph" view to visualize the log data over time.
    • Use the "Timeline" view to see the sequence of events.
    • Use the "Top Events" view to identify the most common events.

Example

Here's an example of a pipeline rule that filters and tags logs based on the log level:

match "log.level": "INFO"
tag "info.log"
