salt.thorium.calc#

Perform calculations against values stored in the Thorium register.

These states are useful when Thorium should react to trends in recent event data instead of reacting to a single event. They are most often paired with reg.list so that a rolling window of values can be evaluated.

New in version 2016.11.0.

statistics PyPi module

salt.thorium.calc.add(name, num, minimum=0, maximum=0, ref=None)#

Adds together the num most recent values. Requires a list.

USAGE:

foo:
  calc.add:
    - name: myregentry
    - num: 5
salt.thorium.calc.calc(name, num, oper, minimum=0, maximum=0, ref=None)#

Perform a calculation on the num most recent values. Requires a list. Valid values for oper are:

  • add: Add last num values together

  • mul: Multiple last num values together

  • mean: Calculate mean of last num values

  • median: Calculate median of last num values

  • median_low: Calculate low median of last num values

  • median_high: Calculate high median of last num values

  • median_grouped: Calculate grouped median of last num values

  • mode: Calculate mode of last num values

USAGE:

load_samples:
  calc.calc:
    - name: load_samples
    - num: 5
    - oper: mean
    - ref: load
    - minimum: 4
salt.thorium.calc.mean(name, num, minimum=0, maximum=0, ref=None)#

Calculates the mean of the num most recent values. Requires a list.

When the register contains dictionaries from reg.list, use ref to select the field to evaluate.

USAGE:

load_samples:
  calc.mean:
    - name: load_samples
    - num: 5
    - ref: load
    - minimum: 4
salt.thorium.calc.median(name, num, minimum=0, maximum=0, ref=None)#

Calculates the mean of the num most recent values. Requires a list.

USAGE:

foo:
  calc.median:
    - name: myregentry
    - num: 5
salt.thorium.calc.median_grouped(name, num, minimum=0, maximum=0, ref=None)#

Calculates the grouped mean of the num most recent values. Requires a list.

USAGE:

foo:
  calc.median_grouped:
    - name: myregentry
    - num: 5
salt.thorium.calc.median_high(name, num, minimum=0, maximum=0, ref=None)#

Calculates the high mean of the num most recent values. Requires a list.

USAGE:

foo:
  calc.median_high:
    - name: myregentry
    - num: 5
salt.thorium.calc.median_low(name, num, minimum=0, maximum=0, ref=None)#

Calculates the low mean of the num most recent values. Requires a list.

USAGE:

foo:
  calc.median_low:
    - name: myregentry
    - num: 5
salt.thorium.calc.mode(name, num, minimum=0, maximum=0, ref=None)#

Calculates the mode of the num most recent values. Requires a list.

USAGE:

foo:
  calc.mode:
    - name: myregentry
    - num: 5
salt.thorium.calc.mul(name, num, minimum=0, maximum=0, ref=None)#

Multiplies together the num most recent values. Requires a list.

USAGE:

foo:
  calc.mul:
    - name: myregentry
    - num: 5
