Service Level Agreement Evaluation: The 8 Best SLA Metrics

Jan 20

Measuring the performance of a service-level agreement (SLA) is critical to assessing the effectiveness of the customer-service provider partnership. A well-established SLA lays the foundation for this assessment, but it is important to have a method for evaluating its performance.

As technology becomes more advanced and critical to daily business operations, ensuring high levels of customer service and satisfaction can become a challenge. To address this, companies need to include service level agreements in their contracts to clearly define expectations and responsibilities and align all parties in their efforts to provide satisfactory service.

In this article, we will explain the importance of service level agreements (SLAs) and their benefits for service providers and customers alike. We will also discuss the importance of evaluating service level agreements on a regular basis and present some of the best SLA metrics. 

What Is a Service Level Agreement?

A service level agreement (SLA) is a contract between a service provider and a customer that specifies the service or level of service that the service provider commits to providing to the customer. The SLA is an important part of any service-based relationship because it sets clear expectations for both parties and provides a framework for managing the relationship.

SLAs typically include details such as:

  • A description of the services to be provided. This section describes the service that the customer can expect from the service provider in terms of functionality and features.
  • the service level targets (such as uptime, response times and availability)
  • Any penalties or credits that may be applied in the event of a service failure or other problem. 

SLAs can also include details such as how service requests are handled, how issues are tracked and resolved, and how the relationship is reviewed and updated over time.

SLAs are used in a variety of industries, including IT, telecommunications, and hosting services. They are also used in other service-based industries, such as healthcare, transportation, and government services.

Why is it important to evaluate service level agreements?

Service Level Agreements (SLAs) are an important part of any service-based relationship, as they set clear expectations for both parties and provide a framework for managing the relationship. However, for SLAs to be effective, it is important to evaluate them regularly to ensure they still meet the needs of both parties.

Below are some reasons why it is important to evaluate SLAs and the benefits that can accrue.

  • Ensuring service quality: One of the main reasons for evaluating SLAs is to ensure that service quality meets agreed standards. Regular monitoring and evaluation of SLAs enables both parties to quickly identify and resolve any problems and ensure that service level targets are met.
  • Identify and address gaps: As business requirements change, it is important to identify any gaps in the service level agreement and address them accordingly. By regularly assessing the SLAs, both parties can ensure that the agreement still meets the current needs of the business and make changes as necessary.
  • Cost savings: In many cases, SLAs include penalties or credits that apply in the event of a service outage or other issues. Regular evaluation of SLAs can help identify areas where the service provider is incurring costs and reduce them, resulting in cost savings for both parties.
  • Compliance and regulation: Compliance with SLAs and regulations evolves over time, and it is important that an organization complies with them. Regular assessment helps meet SLA and regulatory compliance requirements .
  • Maintaining business continuity: Regular assessment of SLAs is critical to maintaining business continuity. An SLA that is not regularly monitored and assessed can lead to service outages and business interruptions that can be costly and detrimental to the customer.

The 8 best metrics for service level agreements

Service Level Agreement (SLA) metrics are used to measure the performance of a service provider against agreed service level targets. These metrics are an essential part of SLAs as they provide both parties with a way to objectively measure the quality of service and identify areas for improvement. 

The actual number of SLA metrics you want to track depends on the service provided and the specific needs of your business. 

1. operating time

Uptime is a measure of the percentage of time a service is available and functioning correctly. It is one of the most important SLA metrics because it directly affects the availability of the service to the customer. The goal of high uptime is to ensure the reliability of the service for the customer. Uptime is usually calculated based on the total number of hours in a given period minus the time the service was unavailable. 

2. reaction time

Response time measures exactly what the name implies: the time it takes a service provider to respond to a customer request or issue. It is an important metric for ensuring that issues are resolved quickly and efficiently, and thus has a major impact on user experience. In general, a slow response time can lead to lost productivity and revenue and damage a company's reputation. 

Response time monitoring enables service providers and customers to identify and resolve performance issues before they become a major problem. It also helps to ensure that the service meets the agreed performance levels and that the customer receives the expected level of service.

3. availability

Availability is a broader metric and refers to the ability of a system or service to perform its intended function. While it is closely related to uptime, it also takes into account other factors such as planned maintenance and upgrades. 

4. throughput

Throughput is a measure of the amount of data that can be processed by a service in a given period of time. It is important for services that process large amounts of data, such as data centers or cloud-based services. Throughput can be measured in different units, e.g. requests per second, transactions per second or data transfer rates.

This metric is particularly important for services that are expected to have a high volume of traffic, such as e-commerce websites, social media platforms, and other types of web-based services.

5. error rate

Error rates indicate the percentage of errors that occur when using a service. It is important to ensure that the service is reliable and that problems are detected and fixed quickly, which is where error rates come in: If a service receives 1000 requests and 20 of them result in an error, the corresponding error rate is 2%.

High error rates can indicate that a service is experiencing problems such as bugs, capacity bottlenecks, or other types of issues. By monitoring the error rate, you can identify problems early and take action to fix them before they become critical.

6. latency

Latency metrics measure the time it takes a service to process a request. Latency plays an important role for real-time services such as streaming services or online games. The goal here is to keep latency at a low level, which is quite difficult to achieve and maintain due to the various factors (such as network conditions, server performance, security protocols, request complexity) that can influence it. 

7. capacity

Capacity is a measure of the resources available to a service, such as storage space or bandwidth. It is important to ensure that the service can handle the load and is not overloaded. 

When a service or system reaches its capacity limits, it can lead to problems such as slow response times, errors, and even complete unavailability. Tracking and monitoring capacity helps service providers and customers identify and fix potential capacity issues before they become a major problem.

Depending on the type of service or system, there are various ways to measure capacity as an SLA metric. For example, for a web server, capacity can be measured by the number of concurrent connections it can handle. For a database, capacity can be measured by the number of queries per second it can process.

8. safety

Although security itself is a rather vague topic and is not usually considered as a standalone SLA metric, there may be some relevant factors that need to be monitored, especially for services that handle sensitive data, such as PCI compliance, penetration testing, encryption measures, access controls, and vulnerability management.


The most important thing to take away from this article is that both parties have a clear understanding of SLA metrics and how they are measured, tracked and reported. This will ensure that both the provider and the customer have a clear understanding of service level expectations and can work together to ensure those expectations are met. 

Again, the metrics included in an SLA may vary depending on the type of service provided, but they should be chosen to accurately reflect the level of service provided. For example, for a web hosting service, uptime and availability would be important metrics, while for a customer service call center, metrics such as call answer time and resolution rate would be more relevant. 

It is also important to determine how metrics will be measured, tracked, and reported so that both parties have a clear understanding of the data that will be used to assess service levels. This may include automated monitoring and reporting tools or regular reports from the service provider.
