\item Call stack sampling might lack time stamps. While you can use such a reduced data set to perform statistical analysis, you won't be able to limit the time range or see the sampling zones on the timeline.
\end{itemize}
\paragraph{Docker on Linux}
Although the basic features will work without them, you'll have to grant elevated access rights to the container running your client. Here is a sample configuration that \textit{may} enable the CPU sampling features\footnote{Tested on Ubuntu 22.04.3, docker 24.0.4}.
\begin{itemize}
\texttt{--privileged}
\texttt{--mount "type=bind,source=/sys/kernel/debug,target=/sys/kernel/debug,readonly"}
\texttt{--user 0:0}
\texttt{--pid=host}
\end{itemize}
\subsubsection{Changing network port}
