Notification for Tablespace Full

Question

This is 10g Grid Control.
I want to be notified by email when a tablespace space usage reaches warning threshold, but couldn't make it work. Here is what I did.
1). Notcifation method has been set and tested.
2). In Preferences -- Notification -- Rules, I created a new one called Tablespace Usage. In which I added a Metris of Tablespace Free Space and checked Three states (Critical, Warning, Clear) for which I want to receive notifications.
But I don't get any notification for Tablespace Space usage even I know for sure some of tablespaces have reached > 90%.
What is wrong here?
Thanks for your reply.

YOu can set on the debugging as well. The script thats being called is sysman/admin/scripts/problemTbsp.pl. In the emd.properties file, you can change the PERL_???? to turn on DEBUG.
stop/start the emctl.
To fire the trigger again - edit the metrics, set it high (must have both warning and critical set due to some bugs) 99 and 100. Set the page refresh to every minute. The metric should clear. Then go set the metric really low say 10 and 20. Again set the refresh to minute - leave it on the screen. It should fire - showing an entry in the bottom half of the screen - regardless of notifications or rules or whatever. This is the first step in diagnosiing this problem.
Note this script problemTBSP.pl has been very buggy - be sure you have the latest version of the script.
$ more problemTbsp.pl

It has special circumstances in there for dictionary vs locally managed, auto extend vs non auto etc etc.
The sql its running is in the script - its not rocket science.
my $sql = "select a.tablespace_name,a.meg, a.maxmeg,a.file_name,a.file_id,a.ts#,
a.blocksize,a.flag, "
. " b.freebytes, b.maxfreebytes,nvl(c.ts#,-99) "
. " from "
. " (select f.tablespace_name, (f.bytes)/1048576 meg, "
. " (f.maxbytes)/1048576 maxmeg, f.file_name, f.file_id, "
. " ts.ts#, ts.blocksize, "
. " DECODE(BITAND(ts.flags,3),1,ts.dflminlen,0) flag "
. " from sys.ts\$ ts, sys.dba_data_files f "

. " AND ( ts.bitmapped = 0 OR (ts.bitmapped != 0 AND bitand(ts.flags,3
) = 0)) "
. " AND bitand(flags,2048) != 2048 "
. " and f.tablespace_name = ts.name) a, "

. " (select distinct s.ts# from sys.seg\$ s where s.maxexts < 2100000000 an
