Prometheus exporter for rustic/restic backup.
Originally I would like to craft a restic-exporter supporting multiple backup repositories because of the issue. After checking the code, I found restic do not separate its library from the CLI. This forces downstream user to rely on subprocess binary calls, which causes additional maintaince overhead. So, I switched gears to rustic, and started this project.
The backup client should use restic >= v0.17, or metrics like rustic_snapshot_size_bytes will be dropped.
Usage: rustic-exporter [OPTIONS] --config <CONFIG>
Options:
-i, --interval <INTERVAL> Metrics collection frequency in seconds [default: 300]
--log-level <LOG_LEVEL> Log level: debug, info, warn, error [default: info]
-v, --verbose Show logs of all dependents
-c, --config <CONFIG> Path to the configuration file
--host <HOST> Server host [default: 0.0.0.0]
--port <PORT> Server port [default: 8080]
-h, --help Print help
-V, --version Print version
The configuration file is in TOML format, and follows the rustic supported services.
