Operationsmanager database is consuming lot of space

Hi All,

I have a issue, My operations manager database is of 40GB and out of which 19 GB was always free.

From the past 1 - 2 weeks my database is occupying lot of space and currently i have only 9GB free.

When i ran a SQL query to pull what data  of what is consuming lot of space below is the report.

SQL Query what i used:

SELECT so.name, 
8 * Sum(CASE WHEN si.indid IN (0, 1) THEN si.reserved END) AS data_kb, 
Coalesce(8 * Sum(CASE WHEN si.indid NOT IN (0, 1, 255) THEN si.reserved END), 0) AS index_kb, 
Coalesce(8 * Sum(CASE WHEN si.indid IN (255) THEN si.reserved END), 0) AS blob_kb 
FROM dbo.sysobjects AS so JOIN dbo.sysindexes AS si ON (si.id = so.id) 
WHERE 'U' = so.type GROUP BY so.name  ORDER BY data_kb DESC

Output:

Last 5 days back the report (When the space came to 12GB)

In last 3 days the new report (Currently when the space came to 9GB)

My Current grooming settings for Operationsmanager DB are as below.

Can any one help me in how do i reduce this space occupation please ?
