Operational
Server Downtime/Uptime
Server Downtime/Uptime measures the reliability and availability of a server or network. Uptime refers to the percentage of time a system is operational and available, while downtime is the period when it is not functioning due to maintenance, failures, or other disruptions.
HOW TO MEASURE
Uptime can be calculated by subtracting the downtime from the total time observed and then dividing by the total time. This result is usually expressed as a percentage to indicate the proportion of time the server was available.
HOW TO IMPROVE
Redundant Systems: Implement redundant hardware and connections to ensure availability even if one component fails.
Regular Maintenance: Schedule regular maintenance to prevent unexpected failures and keep systems running smoothly.
Real-Time Monitoring: Use monitoring tools to detect and resolve issues promptly before they lead to significant downtime.
Quality Hardware and Software: Invest in high-quality equipment and software solutions that offer better reliability and security.
FORMULA
Uptime = ( Total Time - Downtime / Total Time ) × 100%
EXAMPLE
If a company's servers are operational for 29.5 days out of a 30-day month, the downtime is 0.5 days. The uptime would be: Uptime=(30 days−0.5 days/30 days)×100%=98.33%. This indicates the servers were available 98.33% of the time.
DEPARTMENT USAGE
IT and Engineering: To manage and optimize server infrastructure.
Customer Support: To provide accurate information to customers about service availability.
Operations: To assess operational performance and plan for capacity and scalability.
