NAME

qsdt calculates the elapsed time between two related log messages.

SYNOPSIS

qsdt [-t <regex>] -i <regex> -s <regex> -e <regex> [-v] [<path>]

DESCRIPTION

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.

OPTIONS

-t <regex>: 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})
-i <regex>: 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.
-s <regex>: Defines the pattern (regular expression or literal string) identifying the first (start) of the two messages.
-e <regex>: Defines the pattern (regular expression or literal string) identifying the second (end) of the two messages.
-v: Verbose mode.
<path>: Defines the input file to process. qsdt reads from from standard input if this parameter is omitted.

EXAMPLE

Sample command line arguments:

-i ' ([a-z0-9]+) [A-Z]+ ' -s 'Received Request' -e 'Received Response'

matching those sample log messages:
2018-03-12 16:34:08.653 threadid23 INFO Received Request
2018-03-13 16:35:09.891 threadid23 DEBUG MessageHandler Received Response

NOTE

The four patterns (t,i,s,e) are concatenated into two search patterns:
first (start): [t (HH:MM:SS)(SSS) ].*[i (id) ].*[s ]
second (end): [t (HH:MM:SS)(SSS) ].*[i (id) ].*[e ]

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.
