In cloud computing, Service level agreement (SLA) is an important issue. The terms of SLA is a agreement between cloud provider and customer in terms of the quality of cloud service (QoS). The SLA monitoring tools is unpreventable to evaluate the agreed SLAs at operation time and sense any possible SLA violations. The cost and benefit value of SLA monitoring systems is an issue in cloud computing environment. The interval value of monitoring system has a direct impact to the cost and benefit values of monitoring system. Certain monitoring interval is appropriate for specific kind of cloud service in a cloud environment. This paper proposes the dynamic monitoring interval (DMI) to make a balance between cost values and benefit value of SLA monitoring system in different ESs. The DMI adapts interval value based on proposed formula by measuring the cost and benefit of the cloud service monitoring system at run time. The results shows that DMI can adapt with all environment scenario and make a trade-off between cost and benefit value. Indirectly, cloud provider gained benefit in terms of reduce SLA violation and reduce penalty cost.
