popmon package



popmon.config module

class popmon.config.Comparison(**data)

Bases: BaseModel

Parameters related to comparisons

shift: int

shift of time-bins in rolling/expanding window. default is 1.

window: int

size of rolling window and/or trend detection. default is 10.

class popmon.config.Monitoring(**data)

Bases: BaseModel

Parameters related to monitoring

monitoring_rules: Dict[str, List[Union[float, int]]]

monitoring rules to generate traffic light alerts. The default setting is:

monitoring_rules = {
    "*_pull": [7, 4, -4, -7],
    "*_zscore": [7, 4, -4, -7],
    "[!p]*_unknown_labels": [0.5, 0.5, 0, 0],

Note that the (filename based) wildcards such as * apply to all statistic names matching that pattern. For example, "*_pull" applies for all features to all statistics ending on “_pull”. You can also specify rules for specific features and/or statistics by leaving out wildcard and putting the feature name in front. E.g.

monitoring_rules = {
    "featureA:*_pull": [5, 3, -3, -5],
    "featureA:nan": [4, 1, 0, 0],
    "*_pull": [7, 4, -4, -7],
    "nan": [8, 1, 0, 0],

In case of multiple rules could apply for a feature’s statistic, the most specific one applies. So in case of the statistic “nan”: “featureA:nan” is used for “featureA”, and the other “nan” rule for all other features.

pull_rules: Dict[str, List[Union[float, int]]]

red and yellow (possibly dynamic) boundaries shown in plots in the report. Default is:

pull_rules = {"*_pull": [7, 4, -4, -7]}

This means that the shown yellow boundaries are at -4, +4 standard deviations around the (reference) mean, and the shown red boundaries are at -7, +7 standard deviations around the (reference) mean. Note that the (filename based) wildcards such as * apply to all statistic names matching that pattern. (The same string logic applies as for monitoring_rules.)

class popmon.config.Report(**data)

Bases: BaseModel

Report-specific configuration

extended_report: bool

if True, show all the generated statistics in the report (optional) if set to False, then smaller show_stats (see below)

last_n: int

plot statistic data for last ‘n’ periods (optional)

online_report: bool

Use a CDN to host resources, or embed them into the report.

primary_color: str

Primary color used throughout the report

report_filepath: Optional[Union[str, Path]]

the file path where to output the report (optional)

section: Section

Configuration for the individual sections

show_stats: List[str]

list of statistic name patterns to show in the report. If None, show all (optional)

skip_first_n: int

in plot skip first ‘n’ periods. last_n takes precedence (optional)

skip_last_n: int

in plot skip last ‘n’ periods. last_n takes precedence (optional)

title: str

Report title in browser and navbar. May contain HTML.

tl_colors: Dict[str, str]

“Configure line colors in barplots of Comparisons and Profiles section. Need to be hex format (full length)

class popmon.config.Section(**data)

Bases: BaseModel

Configuration for the individual sections

alerts: AlertSection

Configuration related to the alerts section

comparisons: ComparisonsSection

Configuration related to the comparisons section

histograms: HistogramSectionModel

Configuration related to the histogram section

overview: OverviewSection

Configuration related to the overview section

profiles: ProfilesSection

Configuration related to the profiles section

traffic_lights: TrafficLightsSection

Configuration related to the traffic lights section

class popmon.config.Settings(_env_file='<object object>', _env_file_encoding=None, _env_nested_delimiter=None, _secrets_dir=None, **values)

Bases: ValidatedSettings

bin_specs: Dict[str, Any]

dictionaries used for rebinning numeric or timestamp features. An example bin_specs dictionary is:

bin_specs = {
    "x": {"bin_width": 1, "bin_offset": 0},
    "y": {"num": 10, "low": 0.0, "high": 2.0},
    "x:y": [{}, {"num": 5, "low": 0.0, "high": 1.0}],

In the bin specs for x:y, x is not provided (here) and reverts to the 1-dim setting. The ‘bin_width’, ‘bin_offset’ notation makes an open-ended histogram (for that feature) with given bin width and offset. The notation ‘num’, ‘low’, ‘high’ gives a fixed range histogram from ‘low’ to ‘high’ with ‘num’ number of bins.

binning: Literal['auto', 'unit']

default binning to revert to in case bin_specs not supplied. When using “auto”, semi-clever binning is automatically done.

comparison: Comparison

Settings related to the comparisons

features: Optional[List[str]]

columns to pick up from input data. (default is all features). For multi-dimensional histograms, separate the column names with a ‘:’. Example features list is:

features = ["x", "date", "date:x", "date:y", "date:x:y"]

If time_axis is set or found, and if no features provided, features becomes: [‘date:x’, ‘date:y’, ‘date:z’] etc.

monitoring: Monitoring

Settings related to monitoring

reference_type: Literal['self', 'external', 'rolling', 'expanding', 'self_split']

type of reference used for comparisons

report: Report

Settings regarding the report

time_axis: str

name of datetime feature, used as time axis, e.g. ‘date’. (column should be timestamp, date(time) or numeric batch id) if empty string, will be auto-guessed.

class popmon.config.ValidatedSettings(_env_file='<object object>', _env_file_encoding=None, _env_nested_delimiter=None, _secrets_dir=None, **values)
