You can also keep the historical data manageable by tailing the file. Log all values into a single file, such as history.log
At the beginning of the log file processing, execute:
This will give you a smaller file from which to get your historical data. The size of your history.log file will not matter, your processing file will always contain the last 10 entries.

log::any::test
Log::Any::Test(3pm) User Contributed Perl Documentation Log::Any::Test(3pm)NAME
Log::Any::Test -- Test what you're logging with Log::Any
SYNOPSIS
use Test::More;
use Log::Any::Test; # should appear before 'use Log::Any'!
use Log::Any qw($log);
# ...
# call something that logs using Log::Any
# ...
# now test to make sure you logged the right things
$log->contains_ok(qr/good log message/, "good message was logged");
$log->does_not_contain_ok(qr/unexpected log message/, "unexpected message was not logged");
$log->empty_ok("no more logs");
# or
my $msgs = $log->msgs;
cmp_deeply($msgs, [{message => 'msg1', level => 'debug'}, ...]);
DESCRIPTION
"Log::Any::Test" is a simple module that allows you to test what has been logged with Log::Any. Most of its API and implementation have
been taken from Log::Any::Dispatch.
Using "Log::Any::Test" sends all subsequent Log::Any log messages to a single global in-memory buffer. It should be used before Log::Any.
METHODS
The test_name is optional in the *_ok methods; a reasonable default will be provided.
msgs ()
Returns the current contents of the global log buffer as an array reference, where each element is a hash containing a category, level,
and message key. e.g.
{
category => 'Foo',
level => 'error',
message => 'this is an error'
},
{
category => 'Bar::Baz',
level => 'debug',
message => 'this is a debug'
}
contains_ok ($regex[, $test_name])
Tests that a message in the log buffer matches $regex. On success, the message is removed from the log buffer (but any other matches
are left untouched).
does_not_contain_ok ($regex[, $test_name])
Tests that no message in the log buffer matches $regex.
empty_ok ([$test_name])
Tests that there is no log buffer left. On failure, the log buffer is cleared to limit further cascading failures.
contains_only_ok ($regex[, $test_name])
Tests that there is a single message in the log buffer and it matches $regex. On success, the message is removed.
clear ()
Clears the log buffer.
