help needed with nagios alert

[Natva, Arun Kumar]

Hi,
I am using nagios for alerting in our hadoop cluster.

When I setup a check_disk alert on all the nodes in the cluster, we are getting emails for all the hosts even though only one of the nodes exceeds the disk space threshold.

I tried multiple things but I am unable to figure out why nagios sends alerts for all hosts instead of just one host. Can you please help

Regards,
Arun.
