Getting recent changes from VictoriaMetrics (single-node version) for testing purposes

victoria_metrics_test.py

import requests

from random import randint
from time import sleep
from urllib.parse import urljoin

val = randint(1, 100)
requests.post(
    urljoin(host, '/api/v1/import/prometheus'),
    data=f'requests_per_second{{method="post"}} {val}'
)

# Three steps must be taken to get the recent changes

# Step 1: Flush the buffer: /internal/force_flush.
# See https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#forced-flush
# See https://docs.victoriametrics.com/victoriametrics/keyconcepts/#query-latency
requests.get(
    urljoin(host, '/internal/force_flush')
)

# Step 2: Sleep. There is a lag even after flushing the buffer
sleep(1)

# Step 3: Disable the query cache: nocache=1
# See https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#rollup-result-cache
resp = requests.get(
    urljoin(host, '/api/v1/query'),
    params={
        'query': 'requests_per_second',
        'nocache': '1'
    }
)

_, ret_val = resp.json()['data']['result'][0]['value']
assert int(ret_val) == val
