# Prometheus Client Service Output Plugin This plugin starts a [Prometheus](https://prometheus.io/) Client, it exposes all metrics on `/metrics` (default) to be polled by a Prometheus server. ## Configuration ```toml # Publish all metrics to /metrics for Prometheus to scrape [[outputs.prometheus_client]] ## Address to listen on. listen = ":9273" ## Use HTTP Basic Authentication. # basic_username = "Foo" # basic_password = "Bar" ## If set, the IP Ranges which are allowed to access metrics. ## ex: ip_range = ["192.168.0.0/24", "192.168.1.0/30"] # ip_range = [] ## Path to publish the metrics on. # path = "/metrics" ## Expiration interval for each metric. 0 == no expiration # expiration_interval = "60s" ## Collectors to enable, valid entries are "gocollector" and "process". ## If unset, both are enabled. # collectors_exclude = ["gocollector", "process"] ## Send string metrics as Prometheus labels. ## Unless set to false all string metrics will be sent as labels. # string_as_label = true ## If set, enable TLS with the given certificate. # tls_cert = "/etc/ssl/telegraf.crt" # tls_key = "/etc/ssl/telegraf.key" ## Export metric collection time. # export_timestamp = false ```
