The token to use for bearer authentication

token

user

endpoints

Configures an HTTP(S) proxy for Vector to use. By default, the globally configured proxy is used.

proxy

enabled

http

https

A list of hosts to avoid proxying. Allowed patterns here include:

Pattern | Example match
:-------|:-------------
Domain names | `example.com` matches requests to `example.com`
Wildcard domains | `.example.com` matches requests to `example.com` and its subdomains
IP addresses | `127.0.0.1` matches requests to 127.0.0.1
[CIDR](https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing) blocks | `192.168.0.0./16` matches requests to any IP addresses in this range
Splat | `*` matches all hosts

no_proxy

The interval between scrapes, in seconds.

scrape_interval_secs

Configures the TLS options for incoming connections.

Absolute path to an additional CA certificate file, in DER or PEM format (X.509), or an inline CA certificate in PEM format.

ca_file

Absolute path to a certificate file used to identify this connection, in DER or PEM format (X.509) or PKCS#12, or an inline certificate in PEM format. If this is set and is not a PKCS#12 archive, `key_file` must also be set.

crt_file

Absolute path to a private key file used to identify this connection, in DER or PEM format (PKCS#8), or an inline private key in PEM format. If this is set, `crt_file` must also be set.

key_file

Pass phrase used to unlock the encrypted key file. This has no effect unless `key_file` is set.

key_pass

If `true` (the default), Vector will validate the configured remote host name against the remote host's TLS certificate. Do NOT set this to `false` unless you understand the risks of not verifying the remote hostname.

verify_hostname

The component type. This is a required field for all components and tells Vector which component to use.

type

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 overriden.

The lowercase variant has priority over the uppercase one.

HTTPS_PROXY

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.

HTTP_PROXY

List of hosts to avoid proxying globally.

Allowed patterns here include:
	- Domain names. For example, `example.com` will match requests to to `example.com`
	- Wildcard domains. For example, `.example.com` will match requests to `example.com` and its subdomains
	- IP addresses. For example, `127.0.0.1` will match requests to 127.0.0.1
	- CIDR blocks. For example, `192.168.0.0./16` will match requests to any IP addresses in this range
	- `*` will match all hosts

If another no_proxy value 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.

Prometheus

Prometheus client

Enriches data with useful Prometheus client context.

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

context

Context

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

state

State

Vector uses [OpenSSL](https://www.openssl.org/) for TLS protocols. You can
adjust TLS behavior via the `tls.*` options.

Transport Layer Security (TLS)

prometheus_scrape

A single value that can be incremented or reset to a zero value but *not* decremented.

counter

A gauge represents a point-in-time value
that can increase and decrease. Vector's
internal gauge type represents changes to
that value. Gauges should be used to track
fluctuations in values, like current memory
or CPU usage.

gauge

Also called a **timer**. A histogram samples
observations (usually things like request
durations or response sizes) and counts them
in configurable buckets. It also provides a
sum of all observed values.

histogram

Similar to a histogram, a summary samples
observations (usually things like request
durations and response sizes). While it also
provides a total count of observations and a
sum of all observed values, it calculates
configurable quantiles over a sliding time
window.

summary

The number of events accepted by this component either from tagged
origin like file and uri, or cumulatively from other origins.

events_in_total

The total number of events emitted by this component.

events_out_total

The total number of HTTP error responses for this component.

http_error_response_total

The total number of HTTP request errors for this component.

http_request_errors_total

The total number of errors parsing metrics for this component.

parse_errors_total

The number of bytes processed by the component.

processed_bytes_total

The total number of events processed by this component.
This metric is deprecated in place of using
[`events_in_total`](/docs/reference/configuration/sources/internal_metrics/#events_in_total) and
[`events_out_total`](/docs/reference/configuration/sources/internal_metrics/#events_out_total) metrics.

processed_events_total

request_duration_seconds

The total number of requests completed by this component.

requests_completed_total

A ratio from 0 to 1 of the load on a component. A value of 0 would indicate a completely idle component that is simply waiting for input. A value of 1 would indicate a that is never idle. This value is updated every 5 seconds.
