+Nagios::Passive::BulkResult - submit passive check results to nagios' checkresult_dir in one file

+ for my $check (@checkresults) {
+ my $nw = Nagios::Passive->create(
+ checkresults_dir => undef, # the checkresults_dir key is required here

+Submitting a huge amount of results with L<Nagios::Passive::ResultPath> has some
+limits. Typically a checkresult has a size of 200 bytes or so. But the blocksize
+of most filesystems is about 4K. So a file takes at least 4K of disk space.
+Well, disk space is cheap and nagios deletes the file again after it has
+processed it, but most of the time the checkresults_dir is a memory filesystem.
+And suddenly you waste a lot of RAM. Also reading one large file is faster than
+reading thousands of small files.
+Nagios can handle multiple check results within one file. This is what this
+Module provides. You just create a Nagios::Passive objects with an undefined
+checkresults_dir and add that object to the BulkResult container. When you
+are done, just call C<-E<gt>submit> on the container and one big file is created.
