What types of exporters have you used for collecting metrics in Prometheus?

In Prometheus, the following types of exporters are commonly used for collecting metrics:

• Node Exporter — collects metrics from the operating system (CPU, memory, disk, network).
• Blackbox Exporter — checks the availability and response time of services via protocols like HTTP, DNS, TCP, etc.
• Process Exporter — collects metrics of specific processes.
• Custom Exporters — written in Go or other languages for specific applications.

For example, to monitor a Linux server, a Node Exporter is usually deployed, which exports system metrics in a format understandable by Prometheus.
