Create an Availability Check

In the Control Panel, in the top menu, click Products and select Availability check.
Make sure you have available checks to create — in the top right corner, check the number of created checks and the total number of available checks. If all available checks have been created, order additional ones. Three checks are provided free of charge, regardless of the number of requests for them.
Click Create check.
Enter the check name.
Enter tags for filtering in the check list.
Select the check type.
In the Host/IP field, enter the domain or IP address of the server being checked.
Select the protocol to be used for the check.
Select the check period—how often the check will be performed.
Select the check timeout—the time period after which the check is considered failed.
Select the request sequence for the check. The sequence determines which check points requests will be sent from:
- sequentially—each subsequent request will be performed from the next check point in the list of selected points;
- in parallel—each request will be performed from all selected points simultaneously;
- randomly—each subsequent request will be performed from a random point from the list of selected points.
Specify additional parameters for the selected check type.
Select check points. Their IP addresses are listed—if a firewall is installed on your server, allow these IP addresses in the firewall rules.
Optional: select contacts that will receive notifications about the desired event — a specific check result. By default, a notification for the Unsuccessful event will be created for the selected contacts, which will be sent for any undesirable check result. For example, for a PING check, the Unsuccessful event includes a timeout and a server connection error. You will be able to configure other notifications after creating the check.
If you do not want to display the check on the public statistics page with your account's checks, uncheck Display in public report.
If you do not want the check report to be included in the summary weekly report, uncheck Include in weekly email report.
Optional: test the check — click Test check.
If you want to leave the check inactive, uncheck Enable check immediately after creation.
Click Create and run.
