The Hadoop has multi DataNode, they all listened to a TCP port .
When I used Nagios , I only need to setted up one nagios-Server, one Nagio-client. And It use “check_tcp” to check each DataNode (Each nodes has a same check)
But How can I config Sensu For Hadoop without installing clients on the DataNodes?
I think is there any way to define:
cmd : check_tcp $HOST
cmd: check_aggregate check_data_nodes
the only one clients:
Thank you very much.
