| What does it Monitor? | Invokes HTTP/HTTPS request and checks the availability and performance of your web server from global locations. Monitors HTTP/HTTPS access, DNS resolve time, first byte and throughput | Uses a real browser, (Mozilla Firefox) to check full page load time of your website from global locations
| Monitor the availability and performance of multi-step web transactions, such as online shopping cart | Monitor the availability and performance of multi-step web transactions, such as online shopping cart using a real browser | Checks expiry of SSL/TLS certificate and proper HTTPS handshake | Tests if your DNS Server is resolving properly simulating a real DNS query as configured |
| Ideal for Monitoring | Ideal to make sure website is up with minimum overhead | Ideal to analyze how the website page loads from an end user prespective | Ideal to monitor web application response time. Can be tested more frequenty as it applies lesser load on target application (No JS, CSS, scripts are loaded) | Ideal for monitoring web applications that contain form fillings and AJAX content | SSL certificates of a domain | Ideal for checking DNS servers for performance and outages |
| How does it Monitor? | Invokes server side code (Java) to monitor the website page | Loads full webpage and all elements like HTML, CSS, JS, third party scripts in a real browser | Monitors via server side programs. Actual rendering of a webpage does not occur. Cookies and other session are handled automatically | Monitors via real browser Mozilla Firefox or Chrome. Actual rendering of the webpage takes place. Cookies and other session are handled by the browser | Groups all the SSL certificates linked with a HTTPS server and validates the SSL/TLS Certificate if its expired or not | Initiates a full DNS query and compares the IP returned by the DNS server to a pre-configured set |
| What is analyzed? | Server response time | Load times of all components of a webpage are analyzed | Server response time of the web application sequence. Only HTML content of the requests are analyzed | Multi-step Web Applications. All components of the web reseponse are loaded including CSS, images, links loaded from third party websites and AJAX requests | SSL/TLS Certificate | DNS resolve time for a domain |
| Metrics captured | Supports response time split-up based on DNS time, connection time, first byte time, last byte time and average value | Waterfall model of how the components are loaded. Response time of sub domains or other domains used. IPs, breakup of requests by domains, type of elements are captured | Response time of the actual HTML content is only considered | Response time of the webpage which includes CSS, images, links loaded from third party websites etc. | Domain expiry | Response time of the DNS server |
| Do the Site24x7 monitor support internet / intranet? | Internet and Intranet (via On Premise Poller) | Internet | Internet and Intranet (via On Premise Poller) | Internet | Internet | - |
| Do you support HTTP & HTTPS? | Yes | Yes | Yes | Yes | Only HTTPS | - |

| What is the check frequency supported by the monitor? | 1 minute | 15 minutes | 5 minutes | 5 minutes | Once in a day | 1 minute |
