Analyzer

class Analyzer(data_manager: DataManager, excel_path: Path | str | None = None)

Performs analysis on patch data retrieved via DataManager.

Analyzer class objects are initialized with a DataManager instance and optional Excel file path.

Parameters:

• data_manager (DataManager) – The DataManager instance for retrieving and managing patch data.

• excel_path (Path | str | None) – Path to the Excel file.

initialize_dataframe(excel_path: Path | str) → DataFrame

Initializes a DataFrame by reading the Excel file from the provided path.

Parameters:

excel_path (Path | str) – The path to the Excel file, either as a string or a Path object.

Returns:

A pandas DataFrame loaded from the Excel file.

Return type:

pandas.DataFrame

Raises:

• PatcherError – If the passed excel_file could not be validated (does not exist, or is not a file).

• PatcherError – If the excel file could not be read, if the file is empty, or if the file could not be parsed properly.

static format_table(data: list[list[str]], headers: list[str] | None = None) → str

Formats the data passed into a table for CLI output.

Parameters:

• data (list[list[str]]) – The data to display in the table.

• headers (list[str] | None) – Header names for the columns of the tables.

Returns:

The formatted table as a string.

Return type:

str

filter_titles(criteria: FilterCriteria, threshold: float | None = 70.0, top_n: int | None = None) → list[PatchTitle]

Filters and sorts PatchTitle objects based on specified criteria.

Parameters:

• criteria (FilterCriteria) –

  The criteria to filter and sort by.

  Options include:

  • ’most_installed’: Returns the most installed software by total_hosts.

  • ’least_installed’: Returns the least installed software by total_hosts.

  • ’oldest_least_complete’: Returns the oldest patches with the least completion percent.

  • ’below_threshold’: Returns patches below a certain completion percentage.

  • ’high_missing’: Titles where missing patches are greater than 50% of total hosts.

  • ’zero_completion’: Titles with zero completion percentage.

  • ’top_performers’: Titles with completion percentage greater than 90%.

  • ’installomator’: Titles that have Installomator labels. See Installomator

• threshold (float | None) – The threshold for filtering completion percentages, default is 70.0.

• top_n (int | None) – Number of results to return. If None (default), return all matching results.

Returns:

Filtered and sorted list of PatchTitle objects.

Return type:

list[PatchTitle]

timelapse(criteria: TrendCriteria, datasets: list[Path | str | DataFrame] | None = None, sort_by: str | None = None, ascending: bool = True) → DataFrame

Analyzes trends across multiple datasets based on specified criteria.

Parameters:

• criteria (TrendCriteria) – The trend analysis criteria to use.

• datasets (list[Path | str | pd.DataFrame] | None) – A list of DataFrames or file paths to analyze. If None, uses cached data.

• sort_by (str | None) – A column to sort the results by.

• ascending (bool) – Sorting order (ascending if True, descending if False).

Returns:

A DataFrame with the trend analysis results.

Return type:

pandas.DataFrame

Raises:

PatcherError – If criteria is invalid or data loading fails.

class BaseEnum(new_class_name, /, names, *, module=None, qualname=None, type=None, start=1, boundary=None)

Base class for Enum extensions with reusable CLI parsing.

classmethod from_cli(value: str) → BaseEnum

Maps CLI-friendly inputs (e.g., ‘–most-installed’, ‘–release-frequency’) to Enum values.

Parameters:

value (str) – CLI-friendly string.

Returns:

Corresponding Enum value

Return type:

FilterCriteria | TrendCriteria

Raises:

PatcherError – If the input is invalid

class FilterCriteria(*values)

Enumeration for filtering criteria used in patch data analysis.

class TrendCriteria(*values)

Enumeration for trend analysis criteria.
