Companion with a streaming alarm engine and a notification engine, +is a northbound REST API users can use to interact with Monasca. Hundreds of thousands of metrics per second can be processed [8]. + +2.1.1 Memory usage in HyperV +^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +* Type: 'missing' +* Description: + + + To-be + + - Monasca should collect memory usage in HyperV. + + + As-is: + + - Monasca does not support querying memory usage of HyperV. + + + Gap + + - Monasca does not support querying memory usage of HyperV. + +2.1.2 Memory usage in Libvirt +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +* Type: 'missing' +* Description: + + + To-be + + - Monasca should collect memory usage in Libvirt. + + + As-is: + + - Monasca does not support querying memory usage of Libvirt. + + + Gap + + - Monasca does not support querying memory usage of Libvirt. + +2.2 Heat +========== + +Heat is an orchestration project of openstack. It can be used for deploy application. +Its cfn-hup tool can monitor metadata in VM and notify to heat. But this function is poor now, +we can extend cfn-hup to collect more information inside VM and make failure prediction. + +2.2.1 Cfn-hup +^^^^^^^^^^^^^ + +* Type: 'monitoring issue' +* Description: + + + To-be + + - Cfn-hup is able to collect more metrics than metadata inside VM.
