Frequently Asked Questions
Here are some answers to the most asked questions regarding this product.
How to check if website is down
After registration, add the site to the monitoring and set up notifications in a convenient messenger.
Are my website stats affected?
No, they are not. Most analytics services (like Google Analytics) use JavaScript to collect data and Uptime Conrol\s requests don\t trigger JavaScript.
What are the differences between monitor types?
Here are short details about monitor types:
- http(s): that's perfect for website monitoring. The service regularly sends requests (which are the same as if a visitor is browsing your website) to the URL and decides if it is up or down depending on the HTTP statuses returned from the website (200-success, 404-not found, etc.)
- ping: this is good for monitoring a server. Ping (ICMP) requests are sent and up/down status is decided according to the "if responses are received or not". Ping is not a good fit for monitoring websites as a website (its IP) can respond to ping requests while it is down (which means that the site is down but the server hosting the site is up)
- keyword: checks if a keyword exists or not exists in a web page
- port: good for monitoring services like smtp, dns, pop as all these services run from a specific port and Uptime Robot decides their statuses if they respond to the requests or not.
- cron-job (heartbeat): good for servers/computers/devices that are inside an intranet (but connected to the Internet) and need to be monitored. The feature works in the opposite way compared to other monitoring types. UptimeRobot provides a unique URL for each heartbeat monitor created and expects the monitored item to send regular requests to this URL. Once a regular request doesn’t arrive on time, the monitor is marked as down
