I am looking for a monitoring tool for CPU,MEMORY resources running under AZURE VM and Need Alerts also. We are not looking for paid solutions, but we would like to run a monitoring server. In our cloud, we will launch and remove servicesI wonder what tool is best to monitor hosts and services when they will be added/removed in a daily basis?
I am considering Ganglia, Nagios, Icinga and Sensu. Any other not paid option is welcome too as long as it can monitor the described scenario.
