I regularly order website monitoring. The prices are reasonable, not inflated. The first three checks each month are completely free, and for a pack of five additional metrics, I pay about 150 rubles. In my opinion, the conditions are very favorable. During the monitoring process, the availability of websites is checked. The report that comes in details the server performance, access to ports (TCP/UDP), database status, ping checks, email service functionality, and much more. The report arrives instantly after the check; I have my email set up for notifications, although there is also SMS notification available, but it costs extra (albeit at a symbolic price). The data received allows for an objective assessment of website performance and necessary adjustments. I also used the cloud space from Selectel for a while: storage and virtual private cloud. I have no complaints about the performance of any of the nodes.
