Viewing all open/active sessions?

Post #1 of 4 (5742 views)

Greetings,

Is there an easy way to view all open sessions for a
given instance of Apache::ASP? I realize that it is
possible for me to keep track of this myself, but
since the system manages sessions transparently, I
really don't want to reinvent the wheel. Even a
command-line perl tool to interrogate a state
directory would be great; I just want some way of
measuring active usage at any given time.

Thank you for your help!
Steve

Yes, it is possible.

If you are using Sync::MLDBM as your persistence mechanism then you can
descend through the state directory, looking for sessions that have not
timed out.

Another way to go about it might include:

sub Session_OnStart
{
push @{ $Application->{session_ids} }, $Session->{SessionID};
}

sub Session_OnEnd
{
my @ids = @{ $Application->{session_ids} };
@ids = grep { $_ ne $Session->{SessionID} };
$Application->{session_ids} = \@ids;
}

...Then, to get a list of all active sessions, just access
$Application->{session_ids}

Woops, that would be:

sub Session_OnEnd
{
my @ids = @{ $Application->{session_ids} };
@ids = grep { $_ ne $Session->{SessionID} } @ids;
$Application->{session_ids} = \@ids;
}
