How to use

Netdata setup

Follow these instructions to setup Memcached monitoring in Netdata.

Prometheus setup

Please note that you need Netdata as an exporter for metrics. Plus, these labels are mandatory:

  • job
  • env
  • instance
  • group
  • source

In your prometheus.yml it should look like this:

yaml
- job_name: netdata
  metrics_path: /api/v1/allmetrics?format=prometheus_all_hosts&source=raw
  relabel_configs:
  - source_labels: [__address__]
    regex: ^(.+)\.\w+:\d+
    target_label: instance
    action: replace
  static_configs:
  - targets: [netdata.hostname.here:19999]
    labels:
      env: production
      group: applications
      source: newproject

WARNING: Without these labels, this dashboard won’t be fully functioning.
