qsdt calculates the elapsed time between two related log messages. 
<A NAME="lbAC">&nbsp;</A>
<H2>SYNOPSIS</H2>

qsdt [-t &lt;regex&gt;] -i &lt;regex&gt; -s &lt;regex&gt; -e &lt;regex&gt; [-v] [&lt;path&gt;] 
<A NAME="lbAD">&nbsp;</A>
<H2>DESCRIPTION</H2>

qsdt is a simple tool to search two different messages in a log file and calculates the elapsed time between these lines. The two log messages need a common identifier such an unique request id (UNIQUE_ID), a thread id, or a transaction code. 
<A NAME="lbAE">&nbsp;</A>
<H2>OPTIONS</H2>

<DL COMPACT>
<DT>-t &lt;regex&gt; <DD>
Defines a pattern (regular expression) matching the log line's timestamp. The pattern must include two sub-expressions, one matching hours, minutes and seconds the other matching the milliseconds. Default pattern is ([0-9]{2}:[0-9]{2}:[0-9]{2})[.,]([0-9]{3}) 
<DT>-i &lt;regex&gt; <DD>
Pattern (regular expression) matching the identifier which the two messages have in common. The sub-expression defines the part which needs to be extracted from the matching string. Note: You can also use the start (-s) and end (-e) pattern to define the sub-expression matching this identifier. 
<DT>-s &lt;regex&gt; <DD>
Defines the pattern (regular expression or literal string) identifying the first (start) of the two messages. 
<DT>-e &lt;regex&gt; <DD>
Defines the pattern (regular expression or literal string) identifying the second (end) of the two messages. 
<DT>-v <DD>
Verbose mode. 
<DT>&lt;path&gt; <DD>
Defines the input file to process. qsdt reads from from standard input if this parameter is omitted. 
</DL>

<H2>EXAMPLE</H2>

Sample command line arguments:
<P>
<BR>&nbsp;&nbsp;-i&nbsp;'&nbsp;([a-z0-9]+)&nbsp;[A-Z]+&nbsp;'&nbsp;-s&nbsp;'Received&nbsp;Request'&nbsp;-e&nbsp;'Received&nbsp;Response'
<P>
<BR>&nbsp;matching&nbsp;those&nbsp;sample&nbsp;log&nbsp;messages:
<BR>&nbsp;&nbsp;2018-03-12&nbsp;16:34:08.653&nbsp;threadid23&nbsp;INFO&nbsp;Received&nbsp;Request
<BR>&nbsp;&nbsp;2018-03-13&nbsp;16:35:09.891&nbsp;threadid23&nbsp;DEBUG&nbsp;MessageHandler&nbsp;Received&nbsp;Response
<P>
<A NAME="lbAG">&nbsp;</A>
<H2>NOTE</H2>

The four patterns (t,i,s,e) are concatenated into two search patterns:
<BR>&nbsp;first&nbsp;(start):&nbsp;[t&nbsp;(HH:MM:SS)(SSS)&nbsp;].*[i&nbsp;(id)&nbsp;].*[s&nbsp;]
<BR>&nbsp;second&nbsp;(end):&nbsp;&nbsp;[t&nbsp;(HH:MM:SS)(SSS)&nbsp;].*[i&nbsp;(id)&nbsp;].*[e&nbsp;]
<P>
And the three sub-expression are used to extract the timestamp and the unique identifier that the start and end message have in common. This means that you could specify the sub-expression for the unique identifier in the start (-s) or end (-e) pattern alternatively, e.g. in case the identifier is at the end of the log line.
