In most cases when we want to scrape a node for metrics, we will install node-exporter on a host and configure prometheus to scrape the configured node to consume metric data. We come to this in a moment. Prometheus is configured to scrape the Pushgateway. A simple: docker run -it -p 9091:9091 --rm prom/pushgateway ‍ will give you a Pushgateway container that gets deleted automatically on shutdown on localhost:9091: ‍ Finally, let’s talk about Kubernetes.

I am using pushgateway to exposes metrics coming from short-lived batch jobs. prometheus.yml config. Prometheus is an open source monitoring framework. The monitored application (typically a web service) exposes an HTTP endpoint that returns metrics in the Prometheus format. After the metrics have entered the pushgateway, prometheus already picks them up from there, and this implies several restrictions related to pushing metrics, for example, the absence of the up metric, since it is generated by prometheus itself for the polled app instance, and in this case, it is only the pushgateway. Prometheus is an open-source systems monitoring and alerting toolkit. Continue reading The whole server gets really nice an shiny if combined with a slick dashboard like Grafana..
