• Question 38:

  What is the default URL Prometheus tries to retrieve from a target when gathering monitoring information? (Specify the Full URL, without any host name or scheme)

  A. The default URL that Prometheus tries to retrieve when gathering monitoring information depends on the specific target and the configuration of Prometheus at that time. Prometheus's default behavior is to try to retrieve a scrape target's metrics data from a pre-defined location. For example, if you are monitoring a target that exposes its metrics data on port 8080 of the local network interface, the default URL retrieved by Prometheus would be http://localhost:8080/metrics. However, if the target's metrics data is not on the local interface but rather on another IP address or domain, the URL would change accordingly. Prometheus's default behavior can be modified through configuration files or command-line flags. Therefore, the specific default URL depends on the specific configuration of Prometheus.
