RAS Daemon Input Plugin

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

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 for more details.

Configuration

# 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
