Query: Monitoring in the Clouds: Comparison of ECO2Clouds and EXCESS Monitoring
  Approaches   With the increasing adoption of private cloud infrastructures by providers
and enterprises, the monitoring of these infrastructures is becoming crucial.
The rationale behind monitoring is manifold: reasons include saving energy,
lowering costs, and better maintenance. In the e-Science sector, moreover, the
collection of infrastructure and application-specific data at high resolutions
is immanent. In this paper, we present two monitoring approaches implemented
throughout two European projects: ECO2Clouds and EXCESS. The ECO2Clouds project
aims to minimize CO2 emissions caused by the execution of applications on the
cloud infrastructure. In order to allow for eco-aware deployment and scheduling
of applications, the ECO2Clouds monitoring framework provides the necessary set
of metrics on different layers including physical, virtual and application
layer. In turn, the EXCESS project introduces new energy-aware execution models
that improve energy-efficiency on a software level. Having in-depth knowledge
about the energy consumption and overall behavior of applications on a given
infrastructure, subsequent executions can be optimized to save energy. To
achieve this goal, the EXCESS monitoring framework provides APIs allowing
developers to collect application-specific data in addition to infrastructure
data at run-time. We perform a comparative analysis of both monitoring
approaches, and highlighting use cases including a hybrid approach which
benefits from both monitoring solutions.
