What is Checks?

Checks is an Atatus feature to monitor the health of the services running on your system. The services might be your API servers, databases, queuing systems, etc. Atatus Infra Checks will replace your existing Nagios and Consul monitoring setup. You can set two kinds of checks in infrastructure monitoring:

• HTTP Checks
• TCP Checks

​

HTTP Checks

The HTTP checks is used to monitor a simple HTTP operation. These checks make an HTTP GET request every 10 seconds to the specified URL. The health of the services is based on the HTTP response code: any 200 code series is considered passing and anything else is a failure.

​

TCP Checks

The TCP checks is used to monitor a simple socket operation. These checks make a TCP connection attempt every 10 seconds to the specified IP/hostname and port. The health of the services is based on whether the connection attempt is successful (That is, if the port is currently accepting connections). If the connection is accepted, the status is a success, otherwise, the status is a failure.
