You may have noticed that User Defined Metrics (UDM) in Oracle Enterprise Manager (OEM) have a minimum collection time of 5 minutes.


If you wish to change this interval, you can do so by editing a xml file on the server which is the target of the UDM.


On target server, navigate to ${ORACLE_AGENT_HOME}/sysman/emd/collection and edit file ${ORACLE_SID}.${SERVER}.xml.


Search for the name of the UDM and edit the IntervalSchedule tag e.g.

<CollectionItem NAME="{UDM_NAME}">
<Schedule>
<IntervalSchedule INTERVAL="{n}"/>
</Schedule>
