An Uptime Check makes a request to a URL and monitors the response time and the response code. When looking at the results of specific runs, Rigor will also measure the Time to First Byte and DNS time. If an Uptime check fails, Rigor will return a response code and a traceroute.
Note: Unlike Real Browser checks, an Uptime check makes a request via the curl library. It doesn't parse HTML, or load images or JavaScript.
There are two basic types of Uptime checks:
- HTTP: Ideal for checking the Uptime or response of a single URL or endpoint
- Port: Monitor popular or custom ports on your servers via TCP or UDP protocol
To monitor the Uptime of several URLs, or for more complex transactions, check out our API checks.
