2020-10-27 05:33:26 +08:00
This plugin is only available on Linux (only for `386` , `amd64` , `arm` and `arm64` architectures).
2020-10-21 05:59:05 +08:00
The `RAS` plugin gathers and counts errors provided by [RASDaemon ](https://github.com/mchehab/rasdaemon ).

## Configuration
2020-10-21 05:59:05 +08:00
```toml
[[inputs.ras]]
## Optional path to RASDaemon sqlite3 database.
## Default: /var/lib/rasdaemon/ras-mc_event.db
# db_path = ""
```
In addition `RASDaemon` runs, by default, with `--enable-sqlite3` flag. In case of problems with SQLite3 database please verify this is still a default option.
