Abstract
The ATLAS detector at the Large Hadron Collider reads out particle collision data from
over 100 million electronic channels at a rate of approximately 100 kHz, with a recording rate for
physics events of approximately 1 kHz. Before being certified for physics analysis at computer
centres worldwide, the data must be scrutinised to ensure they are clean from any hardware or
software related issues that may compromise their integrity. Prompt identification of these issues
permits fast action to investigate, correct and potentially prevent future such problems that could
render the data unusable. This is achieved through the monitoring of detector-level quantities
and reconstructed collision event characteristics at key stages of the data processing chain. This
paper presents the monitoring and assessment procedures in place at ATLAS during 2015–2018
data-taking. Through the continuous improvement of operational procedures, ATLAS achieved a
high data quality efficiency, with 95.6% of the recorded proton-proton collision data collected at
√
s = 13 TeV certified for physics analysis.
