You want to monitor both errors and performance in your Django app using Sentry, but only want to sample 20% of transactions to reduce data volume. Which is the correct way to configure traces_sample_rate in sentry_sdk.init()?

Atraces_sample_rate=0.2

Btraces_sample_rate=20

Ctraces_sample_rate='20%'

Dtraces_sample_rate=True

Step-by-Step Solution

Solution:

Step 1: Understand traces_sample_rate meaning
It expects a float between 0.0 and 1.0 representing the fraction of transactions to sample.
Step 2: Match options to correct format
0.2 means 20%, 20 or '20%' are invalid types, True is boolean not a fraction.
Final Answer:
traces_sample_rate=0.2 -> Option A
Quick Check:
Fraction 0.2 = 20% sampling [OK]

Quick Trick: Use decimal fraction for sampling rate [OK]
