Diagnostics

The baglab.diagnostics module helps inspect topic timing and message delivery.

Topic rate

import baglab

rate = baglab.topic_rate(df)
# Returns statistics about the publishing rate

Message gaps

gaps = baglab.message_gaps(df, threshold=0.1)
# Detects periods where messages are missing

Topic delay

delay = baglab.topic_delay(df)
# Measures delay between header.stamp and receive time

Latency chain

chain = baglab.latency_chain(bag, ["/sensor", "/perception", "/planning", "/control"])
# Analyzes end-to-end latency through a processing pipeline
