How do I set up Prometheus with Python?

To set up Prometheus with Python, you can use the prometheus_client library. First, install it using pip: pip install prometheus_client.

What are the basic metrics I can collect?

You can collect various metrics like counters, gauges, histograms, and summaries. For example, use a counter to track requests.

How do I expose these metrics to Prometheus?

You can expose metrics by creating an HTTP endpoint in your Python application. Use start_http_server(port) from the prometheus_client library.

Can you show me a simple code example?

Sure! Here's a simple example:

from prometheus_client import start_http_server, Counter

REQUEST_COUNT = Counter('request_count', 'Total number of requests')

if __name__ == '__main__':
    start_http_server(8000)
    while True:
        REQUEST_COUNT.inc()  # Increment the counter
