The HTTP Client source is experimental. Its configuration and behavior can change in a future release.
Description
This is a pull source. The HTTP Client source polls an HTTP endpoint that you specify on a schedule and ingests the responses into your pipeline. Use it when the data you want lives behind an HTTP endpoint that you want Mezmo to fetch on a regular interval, such as a status or metrics API. This is different from the HTTP source, which is a push source that receives data sent to your pipeline by an external system. You can use the HTTP Client source with both SaaS pipelines and Mezmo Edge deployments. On Mezmo Edge, the source does not check whether the endpoint is reachable from outside your network, so an Edge pipeline can poll endpoints inside your own network.For SaaS pipelines, the HTTP Client source can only poll endpoints that resolve to a public address. Each time it connects, Mezmo checks the address the endpoint resolves to and blocks any endpoint that resolves to an internal, private, loopback, link-local, or other reserved address. This includes cloud metadata services such as
169.254.169.254. If a hostname resolves to a mix of public and restricted addresses, Mezmo drops the restricted ones and connects only to the public ones. If an endpoint resolves only to restricted addresses, the source ingests no data and logs an error on each poll.
