Ambari-1.5.1 ganglia service

Hi,

1.        When a user add a new service like hbase, how and when server
create reconfig or restart command of ganglia for agent ?

2.        What services are monitoringService ? I think ganglia is
monitoringService , howerver its metainfo does not contain monitoringService
properties?

3.        When server execute createHostComponents method(in
AmbariManagementControllerImpl.java), server updates
hostComponent_desired_state in db, I want to know when server use it to
restart ganglia?

 

Thanks !

Hi,

1. After adding a service, the Ganglia configurations are re-created on
a STOP/START combination or RESTART.
2. Ganglia is used for collecting metrics, and Nagios is used for
service monitoring and alerting. You are correct that metainfo does not
contain tagging of services.
3. New host components do not automatically trigger a restart of Ganglia
to pick up configs. A restart of the Ganglia service will do that.

Thanks,
Nate
