Collection errors agent

When the agent can't collect metrics due to collection errors please have a look at the collection message. I ran into the following error :

The number of Volume groups to be monitored is larger than 10. Please add the Volume groups to be monitored in the config file emagent_storage.config

The solution is simple. Add the volumes groups on the target host to the emagent_storage.config located in
$ORACLE_HOME/sysman/emd/emagent_storage.config. The neccessary volume groups can be found with then lsvg command. Put the volume groups between the volumes:START tag en volumes:END tag.

$cat emagent_storage.config
Volumes:START
