RAS Daemon Input Plugin

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

InfluxDB OSS 2.9.0: API tokens are hashed by default

Stronger token security in InfluxDB OSS 2.9.0 — tokens are hashed on disk by default. Existing tokens are hashed on first startup and can’t be recovered afterward. Capture any plaintext tokens you still need before you upgrade.

View InfluxDB OSS 2.9.0 release notes

Hashed tokens authenticate exactly like unhashed tokens — clients and integrations keep working.

Also new in 2.9.0:

  • Configurable backup compression
  • Restore support for backups containing hashed tokens
  • Tighter Edge Data Replication queue validation
  • Flux upgrade
  • Compaction reliability improvements

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On May 27, 2026, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
