My nxs-backup.conf:

project_name: PROJECT
server_name: postgresql

server:
  metrics:
    enabled: false

loglevel: debug

notifications:
  mail:
    enabled: false
  webhooks:
    - webhook_url: "SOME URL"
      message_level: "warning"
      extra_headers:

        "monitoringURL": "-"

include_jobs_configs: ["conf.d/*.conf"]

When I commented out the metrics:

#server:
#  metrics:
#    enabled: false

I received the following error:

# nxs-backup -t
Failed to init metrics: open /tmp/nxs-backup.metrics: permission denied

Fixed by:

chown root: /tmp/nxs-backup.metrics

# nxs-backup -t
The configuration is correct
