1. What is SLA Percentage?

SLA (Service Level Agreement) Percentage measures the uptime of a service relative to its total available time. It's a key metric for assessing service reliability and performance.

2. How Does the Calculator Work?

The calculator uses the SLA Percentage equation:

Where:

• \( Uptime \) — The time the service was available (hours)
• \( Total \) — The total time period being measured (hours)

Explanation: The equation calculates what percentage of the total time the service was available.

3. Importance of SLA Calculation

Details: SLA percentage is crucial for service providers to measure compliance with contractual obligations and for customers to assess service quality.

4. Using the Calculator

Tips: Enter uptime and total time in hours. Both values must be positive numbers, and uptime cannot exceed total time.

5. Frequently Asked Questions (FAQ)

Q1: What is considered a good SLA percentage?
A: Typically 99.9% ("three nines") or higher is considered good, though requirements vary by industry.

Q2: How is SLA different from availability?
A: SLA is a contractual agreement with consequences for non-compliance, while availability is simply a measurement.

Q3: Should planned maintenance be included in SLA calculations?
A: This depends on the specific agreement. Some SLAs exclude planned maintenance windows.

Q4: What's the difference between uptime and availability?
A: Uptime measures total time the system was running, while availability considers whether users could actually access services.

Q5: How often should SLA be measured?
A: Typically measured monthly, but critical services may require more frequent monitoring.
