# Prometheus Output Plugin
|
|
|
|
This plugin starts a [Prometheus][prometheus] client and exposes the written
|
|
metrics on a `/metrics` endpoint by default. This endpoint can then be polled
|
|
by a Prometheus server.
|
|
|
|
⭐ Telegraf v0.2.1
|
|
🏷️ applications

|
|
|
|
## Global configuration options <!-- @/docs/includes/plugin_config.md -->
|
|
|
|
In addition to the plugin-specific configuration settings, plugins support
|
|
additional global and plugin configuration settings. These settings are used to
|
|
modify metrics, tags, and field or create aliases and configure ordering, etc.
|
|
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.
|
|
|
|
[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins
|
|
|
|
## Secret-store support
|
|
|
|
This plugin supports secrets from secret-stores for the `basic_password` option.
|
|
See the [secret-store documentation][SECRETSTORE] for more details on how
|
|
to use them.
|
|
|
|
[SECRETSTORE]: ../../../docs/CONFIGURATION.md#secret-store-secrets
|
|
|
|
## Configuration
|
|
|
|
```toml @sample.conf
|
|
# Configuration for the Prometheus client to spawn
|
|
[[outputs.prometheus_client]]
|
|
## Address to listen on.
|
|
## ex:
|
|
## listen = ":9273"
|
|
## listen = "vsock://:9273"
|
|
listen = ":9273"
|
|
|
|
## Maximum duration before timing out read of the request
|
|
# read_timeout = "10s"
|
|
## Maximum duration before timing out write of the response
|
|
# write_timeout = "10s"
|
|
|
|
## Metric version controls the mapping from Prometheus metrics into Telegraf metrics.
|
|
## See "Metric Format Configuration" in plugins/inputs/prometheus/README.md for details.
|
|
## Valid options: 1, 2
|
|
# metric_version = 1
|
|
|
|
## 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"
|
|
|
|
## Set one or more allowed client CA certificate file names to
|
|
## enable mutually authenticated TLS connections
|
|
# tls_allowed_cacerts = ["/etc/telegraf/clientca.pem"]
|
|
|
|
## Export metric collection time.
|
|
# export_timestamp = false
|
|
|
|
## Set custom headers for HTTP responses.
|
|
# http_headers = {"X-Special-Header" = "Special-Value"}
|
|
|
|
## Specify the metric type explicitly.
|
|
## This overrides the metric-type of the Telegraf metric. Globbing is allowed.
|
|
# [outputs.prometheus_client.metric_types]
|
|
# counter = []
|
|
# gauge = []
|
|
```
|
|
|
|
## Metrics
|
|
|
|
Prometheus metrics are produced in the same manner as the [prometheus
|
|
serializer][].
