Filter Event Table by Frequency

This node filters the traces based on their frequency in the event table. Traces are always sorted based on the frequencies of the corresponding trace variants, and the most frequent trace variants are kept/removed. The filtering strategy is used to determine whether to keep or to remove the most frequent trace variants. The percentage of trace variants to be kept/removed is determined by the two filtering options: filtering type and and filtering threshold.

Options

Keep

The filtering strategy. If this option is enabled, the traces/trace variants that meet the filtering threshold will be kept. Otherwise, the traces/trace variants that meet the filtering threshold will removed.

Trace Variant Filtering

The filtering type. If this option is enabled, the filtering will be applied on the trace variant level; i.e., trace variants that meet the filtering threshold will be kept/removed. If this option is disabled, the filtering threshold is used to set the percentage of traces to be kept/removed.

Threshold

The filtering threshold. It accepts both relative and absolute values (relative values between 0 and 1.0 and absolute integers greater than 1).
