How can I create a metrics dashboard using Prometheus and Python?

You can create a metrics dashboard using Prometheus by first setting up a Python application that exposes metrics via an HTTP endpoint. Then, configure Prometheus to scrape these metrics.

What libraries do I need to use in Python for this?

You can use the prometheus_client library to expose metrics in your Python application. It provides easy-to-use functions for defining and serving metrics.

Can you give me a simple code example?

Sure! Here's a basic example:

from prometheus_client import start_http_server, Summary

# Create a metric to track
REQUEST_TIME = Summary('request_processing_seconds', 'Time spent processing request')

@REQUEST_TIME.time()
def process_request():
    # Simulate a request processing time
    time.sleep(1)

if __name__ == '__main__':
    start_http_server(8000)
    while True:
        process_request()

How do I visualize the metrics in a dashboard?

You can use Grafana to visualize the metrics collected by Prometheus. Simply add Prometheus as a data source in Grafana and create dashboards using the metrics you've defined.
