upsd

UPSD Input Plugin

This plugin reads data of one or more Uninterruptible Power Supplies from a Network UPS Tools daemon using its NUT network protocol.

⭐ Telegraf v1.24.0 🏷️ hardware, server 💻 all

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

# Monitor UPSes connected via Network UPS Tools
[[inputs.upsd]]
  ## A running NUT server to connect to.
  ## IPv6 addresses must be enclosed in brackets (e.g. "[::1]")
  # server = "127.0.0.1"
  # port = 3493
  # username = "user"
  # password = "password"

  ## Force parsing numbers as floats
  ## It is highly recommended to enable this setting to parse numbers
  ## consistently as floats to avoid database conflicts where some numbers are
  ## parsed as integers and others as floats.
  # force_float = false

  ## Emit vendor/product IDs as strings regardless of their value. Avoids
  ## type conflicts when some UPS devices report numeric-looking IDs and
  ## others report alphanumeric. See README for migration notes.
  # stringify_ids = false

  ## Collect additional fields if they are available for the UPS
  ## The fields need to be specified as NUT variable names, see
  ## https://networkupstools.org/docs/developer-guide.chunked/apas02.html
  ## Wildcards are accepted.
  # additional_fields = []

  ## Dump information for debugging
  ## Allows to print the raw variables (and corresponding types) as received
  ## from the NUT server ONCE for each UPS.
  ## Please attach this information when reporting issues!
  # log_level = "trace"

Pitfalls

Please note that field types are automatically determined based on the values. Especially the strings enabled and disabled are automatically converted to boolean values. This might lead to trouble for fields that can contain non-binary values like enabled, disabled and muted as the output field will be boolean for the first two values but string for the latter. To convert enabled and disabled values back to string for those fields, use the enum processor with

[[processors.enum]]
  [[processors.enum.mapping]]
    field = "ups_beeper_status"
    [processors.enum.mapping.value_mappings]
      true = "enabled"
      false = "disabled"

Alternatively, you can also map the non-binary value to a boolean.

Vendor/Product ID types (stringify_ids)

The underlying NUT client library (go.nut) auto-detects numeric-looking values and converts them to int64. This means a vendorid like "0764" becomes int64(764) while a non-numeric vendorid like "ABCD" stays a string. When multiple UPS devices of different vendors write to the same InfluxDB bucket, this causes field type conflicts on ups_vendorid, ups_productid, driver_parameter_vendorid and driver_parameter_productid.

Set stringify_ids = true to force these four fields to always be emitted as strings. The default is currently false to preserve backwards-compatible behavior, but will flip to true in a future release. If the option is left unset, a warning is logged on startup.

[!NOTE] The NUT library parses "0764" into int64(764) before Telegraf sees it, so the stringified value will be "764"; leading zeros are lost and cannot be recovered at this layer.

Metrics

This implementation tries to maintain compatibility with the apcupsd metrics:

• upsd
  • tags:
    • serial
    • ups_name
    • model
  • fields:
    • status_flags (status-bits)
    • input_voltage
    • load_percent
    • battery_charge_percent
    • time_left_ns
    • output_voltage
    • internal_temp
    • battery_voltage
    • input_frequency
    • battery_date
    • nominal_input_voltage
    • nominal_battery_voltage
    • nominal_power
    • firmware

With the exception of:

• tags:
  • status (string representing the set status_flags)
• fields:
  • time_on_battery_ns

Example Output
