How can I use Prometheus for Python metrics?

You can use the prometheus_client library in Python to expose metrics for Prometheus to scrape.

What types of metrics can I collect?

You can collect various metrics like counters, gauges, histograms, and summaries.

Can you show me a simple code example?

Sure! Here's a basic example:

from prometheus_client import start_http_server, Counter

# Create a counter metric
c = Counter('my_counter', 'Description of counter')

if __name__ == '__main__':
    start_http_server(8000)  # Start up the server to expose the metrics
    while True:
        c.inc()  # Increment the counter

How do I configure Prometheus to scrape my metrics?

You need to add a job in your Prometheus configuration file pointing to your Python app's metrics endpoint.
