Monitor SLA Violation Sample Clauses

Monitor SLA Violation. The monitoring of the service is vital to detect if the SP is meeting the defined performance level. If the service is not met, then the customer must be compensated accordingly. Therefore, both parties should actively monitor the service or rely on a TTP monitoring solution. In either case, the monitoring solution must provide reliable measurements, which is a challenge in itself. 5 - Terminate SLA – Depending on the terms defined in Phase #2, the termination of an SLA happens when the SLA validity has expired or when an SLA violation is detected. However, each SLA violation incident is accounted to calcu- late the payment of the compensation value to the customer.

Monitor SLA Violation. SLA violation monitoring begins once an agreement has been established. It plays a critical role in deter- mining whether SLOs are achieved or violated. There are three main concerns. Firstly, which party should be in charge of this process. Secondly, how fairness can be assured between parties. Thirdly, how the boundaries of SLA violation are defined. SLA violation means „un-fulfillment‟ of service agreement. According to the Principles of European Con- tract Law, the term „un-fulfillment‟ is defined as defective performance (parameter monitored at lower level than agreed), late performance (service delivered at the appropriate level but with unjustified de- lays), and no performance (service not provided at all). There are three broad provisioning categories based on the above definition (Rana et. al. 2008). „All-or-Nothing‟ provisioning, characterizes the case in which all SLOs must be satisfied or delivered by the provider. „Partial‟ provisioning identifies some SLOs as mandatory ones, and must be met for the successful service delivery by both parties. „Weighted Partial‟ provisioning, is the case in which the “provision of a service meets SLO if it has a weight greater than a threshold (defined by the client)” (Xxxx et. al. 2008). „All-or-Nothing‟ provisioning is used in most cases of SLA violation monitoring, because violation leads to complete failure and negotiation to create a new SLA. An SLA contains mandatory SLOs that must be delivered by the provider. Hence, in „Partial‟ provisioning, all parties assign these SLOs the highest priority to reduce violation risk. How much the SLO affects the „Business Value‟ a measure of the importance of a particular SLO term. The more important the violated SLO, the more difficult it is to renegotiate the SLA, because any party does not want to lose their competitive advantages in the market.

Monitor SLA Violation. Monitoring infrastructures are used to measure the difference between the pre-agreed and actual service provision between parties (Rana et. al. 2008). There are three types of monitoring infrastructures, which are trusted third party (TTP), trusted module on the provider side, and trusted module on the client side. Nowadays, TTP provides most of the functionalities for monitoring in most typical situations to detect SLA violation.
