SyslogScan::Usage -- encapsulates the total volumes of mail broadcast, sent, and received through sendmail by a single user or group.

SyslogScan::Volume -- encapsulates a number of messages along with a total number of bytes


# $summary is a SyslogScan::Summary object

use SyslogScan::Usage; my $usage = $$summary{''}; $usage -> dump();

use SyslogScan::Volume; my $broadcastVolume = $usage -> getBroadcastVolume(); my $sendVolume = $usage -> getSendVolume(); my $receiveVolume = $usage -> getReceiveVolume();

print "John Doe sent $$sendVolume[0] messages with $$sendVolume[1] bytes\n";


Broadcast, Send, and Receive

Volume of messages received has the obvious meaning. Volume of messages sent and volume of messages broadcast require more explanation.

If I send out a message which has three recipients, then for the purposes of the SyslogScan modules, I am broadcasting the message once, but I am sending it three times.

Usage methods

new() method

Creates a new, empty Usage object.

addUsage() method and deepCopy() method
   # $usage1 is 4 messages of 100 bytes Received
   # $usage2 is 1 message of 35 bytes Received

   my $usageTotal = $usage1 -> deepCopy();
   # $usageTotal is 4 messages of 100 bytes Received

   $usageTotal -> addUsage($usage2);
   # $usageTotal is 5 messages of 135 bytes Received

Note that because we used deepCopy, $usage1 is still 4 messages of 100 bytes.

registerBroadcast, registerSend, registerReceive methods
    my $usage = new SyslogScan::Usage();
    $usage -> registerSend(512);
    $usage -> registerSend(34);
    $usage -> registerBroadcast(34);
    # $usage is now 2 messages, 546 bytes Sent,
    # and 1 message, 34 bytes Broadcast
getBroadcastVolume, getSendVolume, getReceiveVolume methods

Returns deep copy of the applicable SyslogScan::Volume objects.

static deepCopy method

Returns deep copy of the whole SyslogScan::Usage object.

static dump

Returns a string containing (Message,Bytes) pairs for Broadcast, Send, and Receive volumes.

Volume methods

new() method

Creates a new Volume object of 0 messages, 0 bytes.

deepCopy() method

Creates a new Volume object with the same number of messages and bytes as the current Volume object.

addVolume(), addSize() methods

addVolume() adds the volume of a second Volume object onto the volume of the current Volume object.

addSize() adds on one message of the given size.

    use SyslogScan::Volume;

    my $volume1 = new SyslogScan::Volume();
    $volume1 -> addSize(512);

    my $volume2 = $volume1 -> deepCopy();
    # $volume2 is 1 message, 512 bytes

    $volume2 -> addSize(31);
    # $volume2 is 2 messages, 543 bytes

    $volume2 -> addVolume($volume1);
    # $volume2 is 3 messages, 1055 bytes

    $volume2 -> addVolume($volume2);
    # $volume2 is 6 messages, 2110 bytes
getMessageCount, getByteCount

Gets the number of messages and the total number of bytes, respectively.


Returns the string "getMessageCount(),getByteCount()"

Volume internals

A Volume is simply a two-element array of ($messages, $bytes).

$$volume[0] is the number of messages $$volume[1] is the number of bytes
