Ok EM11g, count of targets has fired and its genuine.
from sysman.mgmt$metric_current mmc
where mmc.target_name=mt.target_name) last_collection
from SYSMAN.MGMT$TARGET MT
group by MT.TARGET_NAME
order by last_collection
Clearly shows a 'cluster database' target with no up to date collections. However, when I select this target in grid and do 'configure', I can test connection ok and it finishes ok. However, the agent is still not collecting data on the target.
The agent logs are clear
The oms emoms log/trc are clear
I've tried stopping the agent, clearstating, restarting and also a reload - whilst the error clears it then fires again later. thsi has worked fine, until a reboot of the server. I have noticied the evmlogger crs daemon does not appear to be running...
Any hints appreciated...
