Routes

Versioning

All routes are prefixed by the API version to use, for example /v1 for API version 1. Version(s) currently supported : v1

Alerts

Format

Alerts are described using the following JSON format:

{
  "id": uuid
  "name": string,
  "measurement_id": uuid,
  // "activation_timeranges": [{
  //   "id": uuid,
  //   "timeUnit": "day"|"hour"|"minute"|"second",
  //   "start": integer
  //   "end": integer
  // }],
  "activated": boolean, // temporary, while activation_timeranges is not supported
  "actions": [{
    // see actions description
  }],
  "triggers": [{
    // see triggers description
  }]
}

Actions

{
  "id": uuid,
  "type": "webhook",
  "webhook": {
    "url": "",
    // oauth2
  },
  "ratelimits": [{
    "timeUnit": "day" | "hour" | "minute" | "second",
    "timeValue": integer,
    "maxTriggers": integer
  }]
}

GET /alerts/:alert_id

Returns alert with the JSON format described above.

Status codes:

  • 200 OK (resource exists, return the alert in body)
  • 500 Internal Server Error (error while getting the entity)
  • 410 Gone (resource does not exist, but existed previously)
  • 404 Not found (resource never existed)
  • 406 Not Acceptable (‘accept’ header not supported)

GET /alerts

Returns an array of alerts with the JSON format described above. Query string:

  • measurement_id: string -> filter alerts on the specified measurement (may be specified multiple times to filter on several measurement ids)
  • tag: string -> filter alerts on the specified tag
  • tags: string[] -> filter alerts on the specified tags

Status codes:

  • 200 OK (get succeeded, return the alerts in body)
  • 500 Internal Server Error (error while getting the entities)
  • 404 Not found (resource never existed)
  • 406 Not Acceptable (‘accept’ header not supported)

DELETE /alerts/:alert_id

Algo: don’t delete, just set to NULL. created_at updated_at deleted_at => NULL || NOW()

Status codes:

  • 200 OK (delete succeeded, don't return any body)
  • 500 Internal Server Error (error while deleting the entity)
  • 410 Gone (ressource does not exists, but excited previously)
  • 404 Not found (ressource never existed)

PUT /alerts/:alert_id

Check schema if invalid => 401 Do query an error occured ? -> 500 success ? resource created ? 201 resource already existed ? 204

Status codes:

  • 201 Created (once the resource is created)
  • 204 No Content (the resource was updated)
  • 401 Malformed (schema validation failed)
  • // 409 Conflicts (if the alert already exists), http://httpstatus.es/409
  • 500 Internal Server Error (could not create resource)

Triggers

Triggers analyze the data (or the absence of data) recorded by your measurements and determine whether or not to trigger an alert.

no_data

A no_data trigger is defined using the following JSON structure :

{
  "operator": {
    "name": "no_data",
    "rate": {
      "timeUnit": "day" | "hour" | "minute" | "second",
      "timeValue": integer
    }
  },
  "target": "data" | "data.X"
}

any_data

An any_data trigger is defined using the following JSON structure :

{
  "operator": {
    "name": "any_data",
    "rate": {
      "timeUnit": "day" | "hour" | "minute" | "second",
      "timeValue": integer
    }
  },
  "target": "data" | "data.X"
}

anomalous

anomalous trigger is defined using the following JSON structure :

{
  "operator": {
    "name": "anomalous"
  },
  "target": "data" | "data.X"
}

value

{
  "operator": {
    "name": "threshold_min",
    "duration": {
      "timeUnit": "day" | "hour" | "minute" | "second",
      "timeValue": integer
    }
  },
  "target": "data" | "data.X",
  "value": number
}
{
  "operator": {
    "name": "equal",
    "duration": {
      "timeUnit": "day" | "hour" | "minute" | "second",
      "timeValue": integer
    },
  },
  "target": "data" | "data.X",
  "value": number
}
{
  "operator": {
    "name": "threshold_max"
    "duration": {
      "timeUnit": "day" | "hour" | "minute" | "second",
      "timeValue": integer
    },
  },
  "target": "data" | "data.X",
  "value": number,
}

attribute

newValuetrigger is defined using the following JSON structure :

{
  "operator": {
    "name": "newValue"
  },
  "target": "data"
}

v2

Avoir une route qui liste les operators (et leurs capacités en fonction des triggers) -> modifier schéma de BDD

A chaque fois que l’on envoie un point, il est possible de préciser en plus du data et du metadata un tags:[], ces tags seront automatiquement ajouté au set de tags de measurements.

Troubleshooting

- type "citext" does not exist

Connect to the database using the "citext" type, and run "CREATE EXTENSION citext".
