RAS Daemon Input Plugin

This plugin is only available on Linux (only for 386, amd64, arm and arm64 architectures).

The RAS plugin gathers and counts errors provided by RASDaemon.

Global configuration options

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 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

Permissions

This plugin requires access to SQLite3 database from RASDaemon. Please make sure that user has required permissions to this database.
