Hello, thanks for the contribution, this is great!

Just a thought, would it be a good idea to update the all_metrics function to use this functoin internally like so:

self.get_label_values(label_name="__name__")

/cc @4n4nd @lixir

Hi @4n4nd! I have added tests for get_label_values() in b64d90a.

lixir · 2022-01-09T04:52:15Z

tests/test_prometheus_connect.py

+        self.assertEqual(metrics_list, self.pc.get_label_values("__name__"))
+        # Check for the "job" label.
+        label_values = self.pc.get_label_values("job")
+        self.assertTrue(len(label_values) > 0, "no metrics received from prometheus")


Here I added a check for this label(job) for your test server (http://demo.robustperception.io:9090/). I am comparing the number of values to zero. If you need to compare the result with the current value and it will not change over time, I can make an edit.
Current value for "job" label: ['alertmanager', 'node', 'prometheus', 'pushgateway']
