editPrometheus collector metricset
editThe Prometheus collector
metricset scrapes data from prometheus exporters.
Scraping from a Prometheus exporter
editTo scrape metrics from a Prometheus exporter, configure the hosts
field to it. The path
to retrieve the metrics from (/metrics
by default) can be configured with metrics_path
.
- module: prometheus period: 10s hosts: ["node:9100"] metrics_path: /metrics #username: "user" #password: "secret" # This can be used for service account based authorization: #bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token #ssl.certificate_authorities: # - /var/run/secrets/kubernetes.io/serviceaccount/service-ca.crt
Scraping all metrics from a Prometheus server
editThis module can scrape all metrics stored in a Prometheus server, by using the federation API. By pointing this config to the Prometheus server:
metricbeat.modules: - module: prometheus period: 10s hosts: ["localhost:9090"] metrics_path: '/federate' query: 'match[]': '{__name__!=""}'
