KairosDB Aggregators

This project provides custom aggregators for KairosDB. See https://kairosdb.github.io/docs/build/html/kairosdevelopment/Aggregators_and_GroupBys.html for installation instructions.

Score Aggregator

Scores the data based on a set of thresholds. Each data point will be mapped to a value between 0 and n where n is the number of thresholds.

Parameters:

• order: the order by which scores are assigned. Either ascending or descending.
• thresholds: a set of thresholds
  • value: the threshold value
  • boundary: determines how to compare against values equal to the threshold value. One of either superior or inferior. Values equal to the threshold value are greater than thresholds with inferior boundaries and less than thresholds with superior boundaries.

Example:

{
    "name": "score",
    "order": "ascending",
    "thresholds": [
        {
            "value": 0,
            "boundary": "superior"
        },
        {
            "value": 10,
            "boundary": "inferior"
        }
    ]
}

The above configuration would yield the following results:

raw data point	aggregated data point
-1	0
0	0
1	1
10	2
11	2

The same configuration with descending order would yield equivalent results, except with inverted scores:

raw data point	aggregated data point
-1	2
0	2
1	1
10	0
11	0
