Erlang library to forward Prometheus metrics to a Cortex/Prometheus instance
Tested writing to cortex, might also work with Prometheus directly.
Collects metrics from the default registry of Prometheus lib.
Example:
[{cortex_remote_write, [
{interval, 15000},
{url, "URL"},
{username, "USERNAME"},
{password, "PASSWORD"},
{default_labels, [
{"label_name", "label_value"}
]}
]}].
interval - in Milliseconds to trigger metric collection/sending.
If url is not specified, the supervisor will not start the writer process.
username and password are required if url is present.
A proplist/ list of key-value pairs.
Value can be:
* A string
* A binary
* {env, Name} - Name being the name of an environment variable to lookup
default_labels defaults to [].
