How to find date Difference in AWK/GAWK with millisecond precision
Hi,
I have a log file that has the date in this format
"2006-05-30_13:14:04,256". I need to find the time difference between two log entries in milliseconds.
How to achieve this in AWK/GAWK script?

varnishhist
VARNISHHIST(1) VARNISHHIST(1)
NAME
varnishhist - Varnish request histogram
SYNOPSIS
varnishhist [-b] [-C] [-c] [-d] [-I regex] [-i tag] [-m tag:regex ...] [-n varnish_name] [-r file] [-V] [-w delay] [-X regex] [-x tag]
DESCRIPTION
The varnishhist utility reads varnishd(1) shared memory logs and presents a continuously updated histogram show- ing the distribution of
the last N requests by their processing. The value of N and the vertical scale are dis- played in the top left corner. The horizontal
scale is logarithmic. Hits are marked with a pipe character ("|"), and misses are marked with a hash character ("#").
The following options are available:
-b Include log entries which result from communication with a backend server. If neither -b nor -c is specified, varnishhist acts as
if they both were.
-C Ignore case when matching regular expressions.
-c Include log entries which result from communication with a client. If neither -b nor -c is specified, varnishhist acts as if they
both were.
-d Process old log entries on startup. Normally, varnishhist will only process entries which are written to the log after it starts.
-I regex
Include log entries which match the specified regular expression. If neither -I nor -i is specified, all log entries are included.
-i tag Include log entries with the specified tag. If neither -I nor -i is specified, all log entries are included.
-m tag:regex only count transactions where tag matches regex. Multiple
-m options are AND-ed together.
-n Specifies the name of the varnishd instance to get logs from. If -n is not specified, the host name is used.
-r file
Read log entries from file instead of shared memory.
-V Display the version number and exit.
-w delay
Wait at least delay seconds between each update. The default is 1. file instead of displaying them. The file will be overwritten
unless the -a option was specified.
-X regex
Exclude log entries which match the specified regular expression.
-x tag Exclude log entries with the specified tag.
