How do I use the Prometheus Python client?

To use the Prometheus Python client, first install it using pip: pip install prometheus_client. Then, you can start by importing it in your Python script.

What are the basic metrics I can track?

You can track various metrics like counters, gauges, histograms, and summaries. Each serves different purposes, such as counting events or measuring durations.

Can you show me a simple example?

Sure! Here's a simple example:

from prometheus_client import start_http_server, Counter

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

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

How do I expose these metrics to Prometheus?

Once your application is running, Prometheus can scrape the metrics from the endpoint you specified (e.g., http://localhost:8000/metrics). Make sure to configure Prometheus to scrape this endpoint.
