The \texttt{btrecord} and \texttt{btreplay} tools provide the ability to
|
|
record and replay IOs captured by the \texttt{blktrace} utility. Attempts
|
|
are made to maintain ordering, CPU mappings and time-separation of IOs. The
|
|
general workflow is expected to be:
|
|
|
|
\begin{enumerate}
|
|
\item Initiate \texttt{blktrace} to capture traces
|
|
\item Generate traces\ldots
|
|
\item Stop \texttt{blktrace}
|
|
\item Run \texttt{btrecord} to convert traces into IO records
|
|
\item Utilize \texttt{btreplay} to replay IOs
|
|
\end{enumerate}
|
|
|
|
This document will discuss the operating characteristics of
|
|
\texttt{btreplay} and provide detailed command line option descriptions.
