You can install ganglia and use the Ambari-shipped ganglia metrics w/out using Ambari, I was able to do that on a cluster w/out Ambari server. It's most likely true with Nagios as well.
From: Bill Sparks [mailto:[email protected]] Sent: Wednesday, September 11, 2013 12:15 PM To: [email protected] Subject: ambari just for monitoring? Is it possible to just use Ambari for just monitoring and not for the initial provisioning/setup ? Our system is somewhat strange in it's architecture and use of read-only root filesystems, so the per-node install and setup will not work. Using Ambari as the single point for monitoring the Hadoop ecosystem components would be useful. Thanks. Bill.
