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.

Configuration

[[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.
