PRTG makes web service monitoring as easy as it gets
Custom alerts and data visualization let you quickly identify and prevent service disruptions and other performance issues.
Keep your web services running like a champ with PRTG
Web services are the backbone of modern business. Paessler PRTG's web service monitoring makes sure everything stays healthy, from HTTP status to response times. You'll catch issues before users do, optimize performance, and reduce troubleshooting time.
Keep a close eye on performance
Your web service doesn't live in a vacuum. PRTG tracks HTTP request-response times, DNS resolution times, and web server availability with continuous performance monitoring.
A clear line of sight into your performance data promptly reveals stress points in APIs, websites, and microservices, so you can address specific bottlenecks before they affect user experience.
Stay ahead with proactive monitoring
Don't wait for users to report problems – catch them first. PRTG's synthetic monitoring proactively simulates user interactions and HTTP transactions to test the availability, response times, and endpoint functionality of your web services, web servers, and websites.
This way, you're always one step ahead of outages, slowdowns, and broken endpoints.
Guard against downtime like a pro
Downtime is your enemy, and PRTG keeps you ahead of service interruptions. Using built-in automation, PRTG continuously checks for issues like 404/503 errors, service disruptions, and abnormal response times, alerting you as soon as there’s an issue.
The result? Faster detection, quicker response times, less downtime, and high cost savings.
Track SSL certificate expiration dates
TLS and SSL certificates are easy to overlook – until users see browser warnings or experience service disruptions. PRTG keeps tabs on SSL/TLS certificates to make sure they're valid, up-to-date, and compliant.
You'll receive proactive notifications before expiration, helping you avoid costly service failures and maintain customer trust.
Benchmark your service quality
Don't just hope your web service is fast – prove it. PRTG tracks web application performance, measuring page load times, responsiveness, and uptime.
Generate reports with hard data to share with your team, identify areas for optimization, and make performance-driven decisions to meet your SLAs.
