How to capture tablespace warning and critical messages

Question

Hi,
Where in the database dictionary, the tablespace threshold percent (warning and critical) defined by the user is stored.
Requirement is to set threshold percent (warning and critical) in OEM and in a function (for User-Defined Metrics) or procedure (for scheduler) check for Tablespace PCT_FULL against the set threshold percent and display message accordingly.
Thanks & Regards,
Sanju.

Answer 1

Sounds like this is default behaviour of the metrics for tablespace full?
Here is the basic query for OEM metrics:
select
target_type,
target_name,
metric_column Metric,
decode(warning_threshold,' ',null, decode(warning_operator,'Equal To','=','Not Equal','!=','Greater Than','>','Less Than','<',warning_operator) || ' ' || warning_threshold) Warning,
decode(critical_threshold,' ', null, decode(critical_operator,'Equal To','Not Equal','!=','=','Greater Than','>','Less Than','<',critical_operator) || ' ' || critical_threshold) Critical
from mgmt$metric_collection
--where target_type = 'oracle_emd'
--and  metric_column = 'HostInfovszGrowth'
--and warning_threshold != '20'
--where target_type = 'host'
where-- metric_column like 'tnsPing'
-- (warning_threshold != '80' and critical_threshold != '95')
--and
target_type = 'oracle_database'
--and target_type = 'host'
--and
--target_type  = 'oracle_listener'
--target_type = 'oracle_emd'
--and metric_column like 'generic%'
--and warning_threshold like '%ORA%'
and target_name = 'XXXSOMEHOSTNAMExxxx'
and metric_column = 'pctUsed'
