This section presents the findings of gaps on existing VIM platforms. The focus was to identify gaps based on the features and requirements specified in Section 3.3. The analysis work performed resulted in the identification of gaps of which are herein presented.
Monasca is an open-source monitoring-as-a-service (MONaaS) solution that integrates with OpenStack. Even though it is still in its early days, it is the interest of the community that the platform be multi-tenant, highly scalable, performant and fault-tolerant. 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].
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.
Virtual machine introspection (VMI) is a mechanism that allows indirect inspection and manipulation of the state of virtual machines. It resulted in a variety of VMI-based applications dealing with security, performance, and debugging in virtual machine environments. Of course, it can be used to collect detail metrics in VM and used for failure prediction.
LibVMI is an open source implementation of VMI supporting commodity hypervisors such as Xen and KVM. LibVMI provides the functionality of mapping raw memory pages of VMs inside the privileged VM and relies on monitoring software to interpret the contents of these mapped pages.
