# RAS Daemon Input Plugin
|
|
|
|
This plugin gathers statistics and error counts provided by the local
|
|
[RAS (reliability, availability and serviceability)](https://github.com/mchehab/rasdaemon) daemon.
|
|
|
|
> [!NOTE]
|
|
> This plugin requires access to SQLite3 database from `RASDaemon`. Please make
|
|
> sure the Telegraf user has the required permissions to this database!
|
|
|
|
**Introduced in:** Telegraf v1.16.0
|
|
**Tags:** server
|
|
**OS support:** linux
|
|
|
|
[ras]: https://github.com/mchehab/rasdaemon
|
|
|
|
## Global configuration options <!-- @/docs/includes/plugin_config.md -->
|
|
|
|
In addition to the plugin-specific configuration settings, plugins support
|
|
additional global and plugin configuration settings. These settings are used to
|
|
modify metrics, tags, and field or create aliases and configure ordering, etc.
|
|
See the [CONFIGURATION.md](/telegraf/v1/configuration/#plugins) for more details.
|
|
|
|
[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins
|
|
|
|
## Configuration
|
|
|
|
```toml @sample.conf
|
|
# RAS plugin exposes counter metrics for Machine Check Errors provided by RASDaemon (sqlite3 output is required).
|
|
# This plugin ONLY supports Linux on 386, amd64, arm, and arm64
|
|
[[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.
|
|
|
|
## Metrics
|
|
|
|
- ras
|
|
- tags:
|
|
- socket_id
|
|
- fields:
|
|
- memory_read_corrected_errors
|
|
- memory_read_uncorrectable_errors
|
|
- memory_write_corrected_errors
|
|
- memory_write_uncorrectable_errors
|
|
- cache_l0_l1_errors
|
|
- tlb_instruction_errors
|
|
- cache_l2_errors
|
|
- upi_errors
|
|
- processor_base_errors
|
|
- processor_bus_errors
|
|
- internal_timer_errors
|
|
- smm_handler_code_access_violation_errors
|
|
- internal_parity_errors
|
|
- frc_errors
|
|
- external_mce_errors
|
|
- microcode_rom_parity_errors
|
|
- unclassified_mce_errors
|
|
|
|
Please note that `processor_base_errors` is aggregate counter measuring the
|
|
following MCE events:
|
|
|
|
- internal_timer_errors
|
|
- smm_handler_code_access_violation_errors
|
|
- internal_parity_errors
|
|
- frc_errors
|
|
- external_mce_errors
|
|
- microcode_rom_parity_errors
|
|
- unclassified_mce_errors
