Have you tried a multiple numeric alert? Not familiar with DB2 views, do you know where to get the database from? Can you join to another view for that info from mon_lockwaits? Something like:
select c.tbsp_name, a.count(*)
from sysibmadm.mon_lockwaits a, sysibmadm.mon_get_table b, sysibmadm.container_utilization c
where a.tabname = b.tabname
and b.tbsp_id = c.tbsp_id
group by c.tbsp_name
Just kind of thinking out loud on this. Again, not as familiar with DB2 admin views as other database platforms.
