I'm aware of Metrics, but Ganglia is in fact still available and from what I 
read, supported.  We didn't want to convert over immediately because of the 
dependence on Hbase/Zookeeper requiring additional resources on the cluster, 
and the fact that it's a brand new thing vs something that's been around and 
battle-hardened for years.

Hi Greg,

There's no Ganglia now in Ambari 2.1.

It has been replaced by an internal/local HBase and a metrics collector 
subsystem.

You will find some details on the wiki.

Thanks,
Jayesh

Subject: GANGLIA broken in Ambari 2.1?

In the Centos7 HDP2.3 stack, it attempts to run '/etc/init.d/httpd' which 
doesn't exist, rather than using the 'service' shortcut that does still work, 
even though it forwards to 'systemctl'.  I injected a script into 
/etc/init.d/httpd to work around this, but the stack should probably be fixed.

In the Centos6 HDP2.2 stack, after everything finishes installing Ambari says 
that Ganglia Server is down, even though both httpd and gmetad are up and 
responsive.  You can restart it fine, and it says it's up for a minute or so, 
then says it's down.  Processes are still running, no errors in the logs.  Is 
this a known issue?  Is there a workaround?

Also, since it now installs the 'ganglia-gmond' package instead of the 
versioned 'ganglia-gmond-3.5.0', it gets a conflict with the Centos6 EPEL repo, 
which has version 3.7 available.  I disabled the epel repo for now.

I'll try to gather more details and open a JIRA, but just wondered if someone 
else had run into this and/or solved it.

Thanks,
Greg
