      "type": "internal_metrics"
    }
  }
}
[sources.my_source_id]

sources:
  my_source_id:
    type: internal_metrics

{
  "sources": {
    "my_source_id": {

    scrape_interval_secs: 1

namespace

optional string literal
Overrides the default namespace for the metrics emitted by the source.
default: vector

scrape_interval_secs

optional float
The interval between metric gathering, in seconds.
default: 1 (seconds)

tags

optional object
Tag configuration for the internal_metrics source.

tags.host_key

optional string literal

Overrides the name of the tag used to add the peer host to each metric.

The value is the peer host’s address, including the port. For example, 1.2.3.4:9000.

By default, the global log_schema.host_key option is used.

Set to "" to suppress this key.

How it works

Context

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

State

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

Sending metrics from multiple Vector instances

When sending internal_metrics from multiple Vector instances to the same destination, you will typically want to tag the metrics with a tag that is unique to the Vector instance sending the metrics to avoid the metric series conflicting. The tags.host_key option can be used for this, but you can also use a subsequent remap transform to add a different unique tag from the environment.
