Here comes a “frequently requested feature”: Monitoring Ports.
Uptime Robot now enables you to monitor any port/service (like HTTP, FTP, DNS, SMTP, POP, IMAP, etc.) and find out if they are responding or not.
Under the re-organized “Add New Monitor” menu, the feature can be reached by simply selecting “TCP Ports”.
After that, Uptime Robot will be displaying a list of pre-defined/popular ports and the ability to define a custom port.
There are usually 2 status options while monitoring a service, it can be:
- up
- or down
However, there is a 3rd option from Uptime Robot‘s point of view: it can also be filtered/firewalled. Simply, it can be up or down but the status can not be detected as any requests (like Uptime Robot does) are blocked.
Good news is; if the port/service is behind a firewall and blocks any requests, inside the “down” e-mail notification, you’ll see that Uptime Robot mentions this information.
So, if you have the chance of whitelisting IPs that can reach to the port. If you prefer to, whitelisting Uptime Robot‘s IPs would help the monitor to work (IPs can be found in the “About” page.).
Hope you like this new feature and, now, we can focus on some more tasty stuff : )
