Nagios escalating prematurely

We are currently using Nagios 1.3 .The issue we facing is , when a alert is in Warning state and then from Warning it moves to Critical state ,the alert is escalated directly to L2,L3 L4 escalations,here nagios assumes that the time period ,the alert was in warning state as unacknowledged time (even when it is acknowledged ),and it follows the L2 ,L3 escalation path depending on the time we have defined for the esclations.

Is this a bug or a feature of nagios and is there a way to fix this problem as escalation to TOP management is major thing because it is direct impacting to our SLAs.

NAME

       Nagios::Plugin::Performance - class for handling Nagios::Plugin performance data.

SYNOPSIS

	 use Nagios::Plugin::Performance use_die => 1;

	 # Constructor (also accepts a 'threshold' obj instead of warning/critical)
	 $p = Nagios::Plugin::Performance->new(
	     label     => 'size',
	     value     => $value,
	     uom       => "kB",
	     warning   => $warning,
	     critical  => $critical,
	     min       => $min,
	     max       => $max,
	 );

	 # Parser
	 @perf = Nagios::Plugin::Performance->parse_perfstring(
	     "/=382MB;15264;15269;; /var=218MB;9443;9448"
	 )
	 or warn("Failed to parse perfstring");

	 # Accessors
	 for $p (@perf) {
	   printf "label:    %s
",   $p->label;
	   printf "value:    %s
",   $p->value;
	   printf "uom:      %s
",   $p->uom;
	   printf "warning:  %s
",   $p->warning;
	   printf "critical: %s
",   $p->critical;
	   printf "min:      %s
",   $p->min;
	   printf "max:      %s
",   $p->max;
	   # Special accessor returning a threshold obj containing warning/critical
	   $threshold = $p->threshold;
	 }

	 # Perfdata output format i.e. label=value[uom];[warn];[crit];[min];[max]
	 print $p->perfoutput;

DESCRIPTION

       Nagios::Plugin class for handling performance data. This is a public interface because it could be used by performance graphing routines,
       such as nagiostat (http://nagiostat.sourceforge.net), perfparse (http://perfparse.sourceforge.net), nagiosgraph
       (http://nagiosgraph.sourceforge.net) or NagiosGrapher (http://www.nagiosexchange.org/NagiosGrapher.84.0.html).

       Nagios::Plugin::Performance offers both a parsing interface (via parse_perfstring), for turning nagios performance output strings into
       their components, and a composition interface (via new), for turning components into perfdata strings.

USE'ING THE MODULE
       If you are using this module for the purposes of parsing perf data, you will probably want to set use_die => 1 at use time. This forces
       &Nagios::Plugin::Functions::nagios_exit to call die() - rather than exit() - when an error occurs. This is then trappable by an eval. If
       you don't set use_die, then an error in these modules will cause your script to exit

CLASS METHODS

       Nagios::Plugin::Performance->new(%attributes)
	   Instantiates a new Nagios::Plugin::Performance object with the given attributes.

       Nagios::Plugin::Performance->parse_perfstring($string)
	   Returns an array of Nagios::Plugin::Performance objects based on the string entered. If there is an error parsing the string - which
	   may consists of several sets of data -  will return an array with all the successfully parsed sets.

	   If values are input with commas instead of periods, due to different locale settings, then it will still be parsed, but the commas will
	   be converted to periods.

OBJECT METHODS (ACCESSORS)
       label, value, uom, warning, critical, min, max
	   These all return scalars. min and max are not well supported yet.

       threshold
	   Returns a Nagios::Plugin::Threshold object holding the warning and critical ranges for this performance data (if any).

       rrdlabel
	   Returns a string based on 'label' that is suitable for use as dataset name of an RRD i.e. munges label to be 1-19 characters long with
	   only characters [a-zA-Z0-9_].

	   This calls $self->clean_label and then truncates to 19 characters.

	   There is no guarantee that multiple N:P:Performance objects will have unique rrdlabels.

       clean_label
	   Returns a "clean" label for use as a dataset name in RRD, ie, it converts characters that are not [a-zA-Z0-9_] to _.

	   It also converts "/" to "root" and "/{name}" to "{name}".

       perfoutput
	   Outputs the data in Nagios::Plugin perfdata format i.e.  label=value[uom];[warn];[crit];[min];[max].
