\section{Introduction}
\label{intro}
During the second Long Shutdown (LS2) of the Large Hadron Collider (LHC), the ATLAS experiment has updated various aspects of its offline data quality monitoring software. This paper reviews key changes that have been implemented, with a focus on tools and techniques with potential impact outside of the ATLAS collaboration.
\section{Multithreaded Histogramming in Reconstruction}

\section{Histogram Postprocessing}
It is frequently necessary to perform a processing step on a collected histogram in order to compute a desired result (for example, computing the mean of position residuals to detect problems with detector alignment). To enable multithread-safe filling of histograms, we require that histogram handling in reconstruction software consists entirely of accumulation operations. This implies that merging of histograms is a straightforward operation which merely adds bin contents, and that the order in which events are processed is irrelevant to the final histogram that is produced. It is not in general possible to merge histograms resulting from postprocessing this way. In other contexts this is part of the \textit{map-reduce} paradigm, in which the map step is the collection of the input histograms and the reduction is the production of the postprocessed histograms.  In the new histogramming paradigm only the map step is compatible with running directly in reconstruction.

The Run 2 software did include the capacity to run arbitrary C++ ROOT or PyROOT code on histogram files, but did not provide any services

For bibliography use \cite{RefJ}
\subsection{Subsection title}
\label{sec-2}
Don't forget to give each section, subsection, subsubsection, and
paragraph a unique label (see Sect.~\ref{sec-1}).

For one-column wide figures use syntax of figure~\ref{fig-1}
\begin{figure}[h]
% Use the relevant command for your figure-insertion program
% to insert the figure file.
\centering
\includegraphics[width=1cm,clip]{tiger}
\caption{Please write your figure caption here}
\label{fig-1}       % Give a unique label
\end{figure}

For two-column wide figures use syntax of figure~\ref{fig-2}
\begin{figure*}
\centering
% Use the relevant command for your figure-insertion program
% to insert the figure file. See example above.
% If not, use
\vspace*{5cm}       % Give the correct figure height in cm
\caption{Please write your figure caption here}
\label{fig-2}       % Give a unique label
\end{figure*}

For figure with sidecaption legend use syntax of figure
\begin{figure}
% Use the relevant command for your figure-insertion program
% to insert the figure file.
\centering
\sidecaption
\includegraphics[width=5cm,clip]{tiger}
\caption{Please write your figure caption here}
\label{fig-3}       % Give a unique label
\end{figure}

For tables use syntax in table~\ref{tab-1}.
\begin{table}
\centering
\caption{Please write your table caption here}
\label{tab-1}       % Give a unique label
% For LaTeX tables you can use
\begin{tabular}{lll}
\hline
first & second & third  \\\hline
number & number & number \\
number & number & number \\\hline
\end{tabular}
% Or use
\vspace*{5cm}  % with the correct table height
\end{table}

\begin{thebibliography}{}
%
% and use \bibitem to create references.
