alstat
Provide access summary of your ltsv log file.
Description
alstat parses the tail lines of given ltsv files and prints the summary.
Example
$ cat test.log
method:POST status:200 path:/profile?id=49 reqtime_microsec:7583
method:POST status:404 path:/profile?id=4 reqtime_microsec:8931
method:GET status:404 path:/status?id=40 reqtime_microsec:1735
method:POST status:404 path:/profile?id=10 reqtime_microsec:9546
method:GET status:200 path:/status?id=77 reqtime_microsec:9515
...
Use -l to specify a label to show access counts.
$ alstat -c 0 -l 'method' ./test.log
method access
--------------
GET 40
POST 60
Labels can be combined.
$ alstat -c 0 -l 'method' -l 'status' ./test.log
method status access
----------------------
GET 200 18
GET 404 22
POST 200 24
POST 404 36
Regexps can be used to extract a part of the values.
$ alstat -c 0 -l 'path:(/profile|/status)' ./test.log
path access
----------------
/profile 59
/status 41
The first label can be used as a primary label: -sep separates them
and -rate prints rates for each lines within the primary label.
$ alstat -sep -rate -c 0 -l 'path:(/profile|/status)' -l status ./test.log
path status access (rate)
---------------------------------
/profile 200 24 40.68%
/profile 404 35 59.32%
---------------------------------
/status 200 18 43.90%
/status 404 23 56.10%
-sum sums up the specified fields.
$ alstat -sep -rate -c 0 -l method -l status -sum reqtime_microsec test.log
method status access (rate) sum(reqtime_microsec)
------------------------------------------------------
GET 200 31 58.49% 155181
GET 404 22 41.51% 125124
------------------------------------------------------

-c specifies the display interval in seconds and -c 0 means to print
just once. The default value is 1.
$ alstat -s -r -l 'path:(/profile|/status)' -l status ./test.log
