Prometheus

resticprofile can generate a prometheus file, or send the report to a push gateway. For now, only a backup command will generate a report. Here’s a configuration example with both options to generate a file and send to a push gateway:

[root]
  inherit = "default"
  prometheus-save-to-file = "root.prom"
  prometheus-push = "http://localhost:9091/"

  [root.backup]
    extended-status = true
    no-error-on-warning = true
    source = [ "/" ]

root:
  inherit: default
  prometheus-save-to-file: "root.prom"
  prometheus-push: "http://localhost:9091/"
  backup:
    extended-status: true
    no-error-on-warning: true
    source:
      - /

"root" = {
  "inherit" = "default"
  "prometheus-save-to-file" = "root.prom"
  "prometheus-push" = "http://localhost:9091/"

  "backup" = {
    "extended-status" = true
    "no-error-on-warning" = true
    "source" = ["/"]
  }
}

{
  "root": {
    "inherit": "default",
    "prometheus-save-to-file": "root.prom",
    "prometheus-push": "http://localhost:9091/",
    "backup": {
      "extended-status": true,
      "no-error-on-warning": true,
      "source": [
        "/"
      ]
    }
  }
}

Here’s an example of the generated prometheus file:

# HELP resticprofile_backup_added_bytes Total number of bytes added to the repository.
# TYPE resticprofile_backup_added_bytes gauge
resticprofile_backup_added_bytes{profile="prom"} 70690

User defined labels

You can add your own prometheus labels. Please note they will be applied to all the metrics. Here’s an example:

[root]
  inherit = "default"
  prometheus-save-to-file = "root.prom"
  prometheus-push = "http://localhost:9091/"

  [[root.prometheus-labels]]
    host = "{{ .Hostname }}"

  [root.backup]
    extended-status = true
    no-error-on-warning = true
    source = [ "/" ]

root:
  inherit: default
  prometheus-save-to-file: "root.prom"
  prometheus-push: "http://localhost:9091/"
  prometheus-labels:
    - host: {{ .Hostname }}
  backup:
    extended-status: true
    no-error-on-warning: true
    source:
      - /

"root" = {
  "inherit" = "default"
  "prometheus-save-to-file" = "root.prom"
  "prometheus-push" = "http://localhost:9091/"

  "prometheus-labels" = {
    "host" = "{{ .Hostname }}"
  }

  "backup" = {
    "extended-status" = true
    "no-error-on-warning" = true
    "source" = ["/"]
  }
}

{
  "root": {
    "inherit": "default",
    "prometheus-save-to-file": "root.prom",
    "prometheus-push": "http://localhost:9091/",
    "prometheus-labels": [
      {
        "host": "{{ .Hostname }}"
      }
    ],
    "backup": {
      "extended-status": true,
      "no-error-on-warning": true,
      "source": [
        "/"
      ]
    }
  }
}

which will add the host label to all your metrics.
