I am exposing the memory metrics in Prometheus format from my spring application via micrometer.
The response is following:
# HELP jvm_buffer_count_buffers An estimate of the number of buffers in the pool

But the Metricbeat fails on:
Error fetching data for metricset prometheus.collector: unable to decode response from prometheus endpoint: decoding of metric family failed: text format parsing error in line 12: invalid escape sequence '"'
My configuration is:
metricbeat.autodiscover:
providers:
- type: docker
labels.dedot: true
templates:
- condition:
contains:
docker.container.image: foo
config:
- module: prometheus
period: 10s
metricsets: [ "collector" ]
hosts: [ "http://${data.host}:${data.port}/actuator/prometheus" ]
metrics_path: /metrics
Is it some bug? Or should I make some extra configurations?
