Export report with graphics data

Question

Hi,
i would like to get a long time period report (about 2 month) of performance data with graphics data, same as data on Performance tab of GridControl, is possible to export report of performance with graphics data instead of ASH report that export only data without graph?
thanks very much
Andrea

Hi
Good. The information that you need is stored in the MGMT TABLES but the query can change too much if you change your requirements.
Example
For example CPU % Utilization GC retrieve information from sar comand
sar 60 1440
For IO Waits the GC retrieve information of iostat
But the performance page in GC is the most complex to build a query, because these information are building but PL executions and perl scripts.
Other metrics are more easy
- Blocking session count in database
SELECT blocking_sid, num_blocked
FROM ( SELECT blocking_sid, SUM(num_blocked) num_blocked
FROM ( SELECT l.id1, l.id2,
MAX(DECODE(l.block, 1, i.instance_name||'-'||l.sid,
2, i.instance_name||'-'||l.sid, 0 )) blocking_sid,
SUM(DECODE(l.request, 0, 0, 1 )) num_blocked
FROM gv$lock l, gv$instance i
WHERE ( l.block!= 0 OR l.request > 0 ) AND
l.inst_id = i.inst_id
GROUP BY l.id1, l.id2)
GROUP BY blocking_sid
ORDER BY num_blocked DESC)
WHERE num_blocked != 0
The CPU LOAD in the database performance page establish a maximun cpu line that is equal to processors numbers.
The graphic establish the sessions active for each class and if these are active
You can read the Enterprise Manager Grid Control Extensibility to check all the mgmt views and the metric reference manual to view the data source of each metric
