Section platform has a default built-in HTTP health check that monitors the health of the environment across multiple locations in the world.
Section uses a health check that queries the path
/.well-known/section-io/aee-hc/healthz?ts=<timestamp> to check for health of the entire stack of modules and it’s ability to handle HTTP traffic. The health check is validating the Section edge components, and Section’s ability to communicate with your origin from each PoP, it is not checking the health of your origin.
If your Section environment has multiple domain names associated, the health check will use the first domain name, sorted alphabetically, preferring domain names that are confirmed to have the DNS record directed to Section.
Section uses multiple remote-agents throughout the world to query the environment and then the individiual health responses are aggregated. An individual health response is calculated according to the following conditions:
|DNS fails to resolve||Ignored|
|TLS handshake fails (excluding certificate validation)||NOT healthy|
|Any response status code sent by the origin||Healthy|
|Response status code is
|Response status code is an error, e.g.
|Response status code is any number and does not meet the above conditions||Healthy|

You can use the following example to query your environment and confirm if your environment is healthy to handle HTTP traffic :
curl --head 'https://apps.manibatra.xyz/.well-known/section-io/aee-hc/healthz?ts=12345' \ --header 'section-debug: true' \ --max-time 42 HTTP/2 404 date: Tue, 27 Apr 2021 04:53:20 GMT content-type: text/html content-length: 6118 vary: Accept-Encoding vary: Accept-Encoding etag: "60878fc3-17e6" section-origin-dns-failure: false section-origin-status: 404 section-origin-time-seconds: 0.271 section-io-id: 51a17b0c4b0f233e711ad1a1b256c2fd
In the above example we query an environment with the hostname apps.manibatra.xyz. The above response is deemed healthy according to the conditions mentioned above.
