Metric evaluation error start – EMS-01076: Unexpected error while deploying a plug-in in sync mode for emd url https://hostname:3872/emd/main/: EMS-01015: Error occurred while deploying AGENT plug-in.
if you get the above issue while trying to add targets to cloud control: check the mount options for the /tmp filesystem. if there is the “noexec” attribute this is probably the issue.
to fix it (if you have root):
mount -o remount,exec /tmp
