Prometheusbeat
Prometheusbeat is an elastic beat that can receive Prometheus metrics via the remote write feature.
Example Prometheusbeat configuration:
prometheusbeat:
listen: ":8080"
context: "/prometheus"
# The storage request format had a breaking change starting with Prometheus 1.7.
# Set the version accordingly.
# 1: Prometheus < 1.7
# 2: Prometheus >= 1.7
version: 2
[...]
Example Prometheus configuration:
[...]
remote_write:
url: "http://localhost:8080/prometheus"
