NAME

SNMP::LogParserDriver::ExampleDriver

SYNOPSIS

This is an example Driver class to check for strings in the log file of the form "test string". Every time that this string is found the variable "counter" is incremented.

DESCRIPTION

Here we show each of the functions

new

New is just a passthrough to the parent class

sub new {
  my $class = shift;
  my $self  = $class->SUPER::new();
  bless ($self, $class);
  return $self;
}

evalBegin

Here we initialize the "counter" variable. We declare it in the "savespace" hash so that it is persistent across run invocations of logparser

sub evalBegin {
  my $self = shift;  
  $self->{savespace}{counter} = 0 if (!defined($self->{savespace}{counter}));
  $self->{savespace}{lines} = 0 if (!defined($self->{savespace}{counter}));
}

evalIterate

Here we parse each line, incrementing the counter value if it matches the string (we also keep track of lines)

sub evalIterate {
  my $self = shift;
  my ($line) = @_;
  $self->{savespace}{lines} ++;
  if ($line =~ /test string/g) {
     $self->{savespace}{counter} ++;
  }
}

evalEnd

Here we tell the system that we want to output on the properties file all the variables in the save space...

sub evalEnd {
  my $self = shift;
  $self->properties($self->savespace);
}
