# Health Check

Health checks allow verifying the status of a web server from the perspective of every endpoint. An alert can also be configured to be notified when the health check fails on an endpoint.

### Configure Health Check

Open the *Health Checks* tab and click *New*. Then set the *Name* of the check and set the *Check Type* to *HTTP Request*. Add a role to the health check that will match one of the roles on the endpoint. Every endpoint with a matching role will perform the health check.

The *Targets* is a list of URLs that will be tested with a GET request. The *Check Frequency* is the time in seconds between each check. The *Check Timeout* is the time in seconds before the HTTP request will timeout. The *HTTP Status Code* is the expected status code that will be considered successful. The *HTTP Headers* allow setting headers that will be included in the HTTP request.

Once done click *Save* and after a few minutes data should begin to populate the graphs. The *Error Log* section will provide a log of errors that occur. If configured correctly the name of this health check should be listed in the *Endpoints* page.

Alerts for health checks can also be added with the alert type *HTTP Health Check Failed*.
