    During hmc installation, I am getting the following error during starting nagios services. The nagios logs indicate:

    357363206] SERVICE ALERT:;GANGLIA::Ganglia [gmetad] Process down;CRITICAL;SOFT;1;Connection refused
    [1357363216] SERVICE ALERT:;GANGLIA::Ganglia [gmetad] Process down;CRITICAL;SOFT;2;Connection refused
    [1357363236] SERVICE ALERT:;GANGLIA::Ganglia [gmetad] Process down;CRITICAL;SOFT;3;Connection refused

    [1357363246] SERVICE NOTIFICATION: nagiosadmin;;GANGLIA::Ganglia [gmetad] Process down;CRITICAL;notify-service-by-email;Connection refused

    Ganglia processes did install and started up successfully:’

    Could someone assist?

    Can you please reinstall HDP using Ambari 1.2?

    I had a similar problem, I was seeing these messages:

    Service 	Status 	Last Check 	Duration 	Attempt 	Status Information
    GANGLIA::Ganglia collector [gmond] Process down alert for hbasemaster CRITICAL	02-15-2013 12:37:18	 0d 20h 30m 58s	4/4	Connection refused
    GANGLIA::Ganglia collector [gmond] Process down alert for jobtracker CRITICAL	02-15-2013 12:37:25	 0d 20h 30m 53s	4/4	Connection refused
    GANGLIA::Ganglia collector [gmond] Process down alert for namenode CRITICAL	02-15-2013 12:37:17	 0d 20h 30m 47s	4/4	Connection refused
    GANGLIA::Ganglia collector [gmond] Process down alert for slaves CRITICAL	02-15-2013 12:37:24	 0d 20h 30m 42s	4/4	Connection refused

    On the Nagios host, this seemed to make the errors go away:

    sudo service hdp-gmond start

    On the Nagios host, to permanently fix, add to the header of the init script /etc/init.d/hdp-gmond:

    # chkconfig: 345 20 80
    # description: Starts and stops the agent

    Then add it to the system startup:

    sudo chkconfig --add hdp-gmond
    sudo chkconfig --levels 345 hdp-gmond on


    Hi Trang,

    Thanks for letting us know that you figured out the solution.

    Just an update…

    I was able to resolve this issue by:
    -uninstalling httpd, nagios and puppet on the nagios box
    -uninstalling hmc and puppet
    -rerunning HMC
