Semonto's PulseChecks enable you to keep an eye on a server behind a firewall, a complex NAT situation or a server without an active webserver. Instead of calling and testing your server, your server will ping Semonto frequently. If we don't receive a pulse on time, we will send you a notification. Simple and efficient. Ideal for database servers or to monitor if periodically scripts are running correctly.

PulseCheck use cases

Icon Database

Monitor non-webservers

Database servers are commonly not accessible over the internet. To be able to monitor them it is necessary that these send a pulse to inform that they are still operational. This also allows you to monitor servers behind complex NAT situations.

Icon Backup

Watch periodical scripts

PulseChecks can be used to verify if your cron-jobs have been executed or if periodical back-up tasks are performed. Another usage is for internet of things (IOT) devices to pulse if they are still operational.

Icon Push Notification

Multiple alert options

Semonto has multiple to alert you when a pulse has not been received on time or received again. Push notifications could be sent to our iOS app, alert you by email or SMS. Semonto can even post a tweet or use a custom webhook.

How it works


Create a PulseCheck in Semonto Supervisor. For each PulseCheck Semonto generates a unique URL that your server or script needs to call.


Make sure your server or periodical script pings Semonto on time, by calling the URL.


Once Semonto has received the first pulse of your server, the Pulsecheck is activated. If Semonto does not receive a time before the given timeout, we will alert you.

Icon Settings

Easy configuration

PulseChecks are easy to configure in Semonto Supervisor, the web interface for Semonto. Here you can set the desired time out and define how you would like to be alerted.
