file_exporter

File Exporter

Prometheus Exporter for Files.

Inspired by filestat_exporter.

This project is a little more simplistic and is configurable entirely from the command line, it also monitors for filesystem events and updates the metrics using a library.

It exposes file modified time and the CRC32 hash of the file because it can be represented in float64 which then can be used as a value to a gauge metric in prometheus directly.

Features

• CRC32 of all paths being monitored
• Operations performed on paths such as CREATE, REMOVE, and WRITE
• File modified timed (directories are omitted)

Usage

file_exporter --path path/to/a/file/or/directory

Help

If you do not specify a command, the default is server, so file_exporter --path /tmp and file_exporter server --path /tmp are equivalent.
