Metrics

This interface will serve Prometheus metrics from /metrics. The following metrics are included by default, others are transform specific.

Name	Labels	Data type	Description
`shotover_transform_total`	`transform`	counter	Counts the amount of times the `transform` is used
`shotover_transform_failures`	`transform`	counter	Counts the amount of times the `transform` fails
`shotover_transform_latency`	`transform`	histogram	The latency for running `transform`
`shotover_chain_total`	`chain`	counter	Counts the amount of times `chain` is used
`shotover_chain_failures`	`chain`	counter	Counts the amount of times `chain` fails
`shotover_chain_latency`	`chain`	histogram	The latency for running `chain`
`shotover_available_connections`	`source`	gauge	The number of connections currently connected to `source`

Metric data types

Counter

A single value, which can only be incremented, not decremented. Starts out with an initial value of zero.

Histogram

Measures the distribution of values for a set of measurements and starts with no initial values.

Gauge

A single value that can increment or decrement over time. Starts out with an initial value of zero.

Log levels and filters

You can configure log levels and filters at /filter. This can be done by a POST HTTP request to the /filter endpoint with the env_filter string set as the POST data. For example:
