grafana-cloud.yml

# Use ./alloy/write-loki.yml and ./alloy/write-prometheus.yml to control
# where logs and metrics are being sent
# ./alloy/config.d can have additional configuration files such as custom scrape targets
#
# This file is called grafana-cloud.yml, as adding a remote write to Grafana Cloud is a
# common use case. It properly is a Grafana Alloy without local Grafana, or a local metrics/log store
