Hi Yusaku. Thank you for your response. Other three question:
- Ganglia is going to be replace by Ambari Metric System. Will be the same for Nagios? - If we can not use Ambari, we are thinking in develop an adhoc application for metering and monitoring. We are thinking in use Time Serie Databases to store metric, like Druid or OpenTSDB. Is Amabari going to use any databases of this type? - And the question that maybe you are tired to listen. :) Do you know when is planed to release the version 2.0.0?
