# 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.

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

## Global configuration options

Plugins support additional global and plugin configuration settings for tasks such as modifying metrics, tags, and fields, creating aliases, and configuring plugin ordering. See [CONFIGURATION.md](/telegraf/v1/configuration/#plugins) for more details.

## Configuration

```toml
# 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

## Example Output

```text
ras,host=ubuntu,socket_id=0 external_mce_base_errors=1i,frc_errors=1i,instruction_tlb_errors=5i,internal_parity_errors=1i,internal_timer_errors=1i,l0_and_l1_cache_errors=7i,memory_read_corrected_errors=25i,memory_read_uncorrectable_errors=0i,memory_write_corrected_errors=5i,memory_write_uncorrectable_errors=0i,microcode_rom_parity_errors=1i,processor_base_errors=7i,processor_bus_errors=1i,smm_handler_code_access_violation_errors=1i,unclassified_mce_base_errors=1i 1598867393000000000
