RAS Daemon Input Plugin

This plugin gathers statistics and error counts provided by the local RAS (reliability, availability and serviceability) daemon.

[!NOTE] This plugin requires access to SQLite3 database from RASDaemon. Please make sure the Telegraf user has the required permissions to this database!

⭐ Telegraf v1.16.0 🏷️ server 💻 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 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
