  my_source_id:
    type: eventstoredb_metrics
    default_namespace: eventstoredb
    endpoint: https://localhost:2113/stats
    scrape_interval_secs: 15

default_namespace

optional string literal

Overrides the default namespace for the metrics emitted by the source.

By default, eventstoredb is used.

Examples 
"eventstoredb"

endpoint

optional string literal
Endpoint to scrape stats from.
Examples 
"https://localhost:2113/stats"
default: https://localhost:2113/stats

proxy

optional object

Proxy configuration.

Configure to proxy traffic through an HTTP(S) proxy when making external requests.

Similar to common proxy configuration convention, you can set different proxies to use based on the type of traffic being proxied, as well as set specific hosts that should not be proxied.

proxy.enabled

optional bool
Enables proxying support.
default: true

proxy.http

optional string literal

Proxy endpoint to use when proxying HTTP traffic.

Must be a valid URI string.

Examples 
"http://foo.bar:3128"

proxy.https

optional string literal

Proxy endpoint to use when proxying HTTPS traffic.

Must be a valid URI string.

Examples 
"http://foo.bar:3128"

proxy.no_proxy

optional [string]

A list of hosts to avoid proxying.

Multiple patterns are allowed:

PatternExample match
Domain namesexample.com matches requests to example.com
Wildcard domains.example.com matches requests to example.com and its subdomains
IP addresses127.0.0.1 matches requests to 127.0.0.1
CIDR blocks192.168.0.0/16 matches requests to any IP addresses in this range
Splat* matches all hosts

scrape_interval_secs

optional uint
The interval between scrapes, in seconds.
default: 15 (seconds)

Environment variables

HTTPS_PROXY

common optional string literal

The global URL to proxy HTTPS requests through.

If another HTTPS proxy is set in the configuration file or at a component level, this one will be overridden.

The lowercase variant has priority over the uppercase one.

Examples
http://foo.bar:3128

HTTP_PROXY

common optional string literal

The global URL to proxy HTTP requests through.

If another HTTP proxy is set in the configuration file or at a component level, this one will be overridden.

The lowercase variant has priority over the uppercase one.

Examples
http://foo.bar:3128

NO_PROXY

common optional string literal

List of hosts to avoid proxying globally.

Allowed patterns here include:

PatternExample match
Domain namesexample.com matches requests to example.com
Wildcard domains.example.come matches requests to example.com and its subdomains
IP addresses127.0.0.1 matches requests to 127.0.0.1
CIDR blocks192.168.0.0./16 matches requests to any IP addresses in this range
Splat* matches all hosts

If another no_proxy value is set in the configuration file or at a component level, this one is overridden.

The lowercase variant has priority over the uppercase one.

Examples
localhost,.example.com,192.168.0.0./16

How it works

Context

By default, the eventstoredb_metrics source augments events with helpful context keys.

State

This component is stateless, meaning its behavior is consistent across each input.
