Choose Alloy components
In Alloy, a component is a building block that does one specific job in collecting, processing, or sending telemetry data. It’s similar to a LEGO piece where each one has a specific purpose, and you connect them to build a working pipeline.
When choosing which components to use, plan out the pipeline you want to create first and visualize the flow of data. Once you have a rough guide, refer to the Alloy Components page for all the available components.
The following diagram shows the basic minimum components for sending system logs to Loki.
local.file_match- This component searches for log files on your system based on a pattern (like/var/log/*.log).loki.source_file- This component reads log lines from the files found bylocal.file_match. It parses the logs to prepare them for Loki.loki.write- This component sends the processed logs to a Loki backend.
In the next milestone, you’re going to edit the Alloy configuration file to send logs to Loki.
