Fluentd、Elasticsearch

Fluentd and Elasticsearch are two software tools that are often used together to collect and analyze data in real-time.

Fluentd is an open-source data collection tool that can collect data from a variety of sources, including logs, metrics, and events. It then normalizes and routes the data to various destinations, such as Elasticsearch or a database. Fluentd is commonly used in DevOps and IT operations to collect and analyze logs from servers, containers, and other infrastructure components.

Elasticsearch, on the other hand, is a search and analytics engine that is designed to store, search, and analyze large volumes of data in real-time. It allows users to easily search and visualize their data, and can be integrated with other tools, such as Kibana and Logstash, to provide a complete data analysis solution.

When used together, Fluentd can be used to collect data from various sources and send it to Elasticsearch for indexing and analysis. This allows users to perform real-time searches and analysis on their data, and can help identify issues and improve system performance. Overall, Fluentd and Elasticsearch are powerful tools for data collection and analysis, and are commonly used in DevOps and IT operations.
