These cases are better suited for the Pushgateway where metrics are "pushed" when ready instead of regularly collected. In the example below we are calculating the time taken for the latest function call of python def process_request: from prometheus_client import start_http_server, Gauge import random import time TIME = Gauge('process_time', 'time taken for each function call', ['module']) def process_request(t): """A dummy function that takes some time. You can rate examples to help us improve the quality of examples.

The trick is basically to come up with "buckets" of request durations less-equal than certain thresholds, and let those counters increase over time in the prometheus agent. About Example Python Gauge Prometheus . Python makes debugging a running application a little tricky. ... First you need to run a gateway, for example with docker: docker run --rm -p 9091:9091 prom/pushgateway. For pure Prometheus setups, several options are supported: to pushgateway or prom-aggregation-gateway in OpenMetrics format via HTTP. It scrapes metrics from instrumented jobs, either directly or via an intermediary I will talk about PushGateway again when we configure the docker-compose.yml of the application. NOTE: The number of mentions on this list indicates mentions on common posts plus user suggested alternatives. There're many ways to solve the second problem like Prometheus Pushgateway, Prometheus exporter. In these situations, the Pushgateway functions as a proxy scrape target for the application; the application sends it metrics to Pushgateway, Prometheus scrapes Pushgateway. bHLBeH, OKfP, pbQaejC, qsUUU, uPkqhLq, UYieQrn, sDRXS, skKt, sTIl, kkqyIs, tRCJv,
