Properties

A new feature has been added (replacing the data history feature of the previous implementation) called Properties-History. The historical values and date of the Things Properties will be saved each time the value of a thing property is updated. Past values can also be added to the history, in case there has been a disconnection, and we want to have that data recorded.

Note data retention will vary depending on your license.

Check Properties API for more details.

Example

As mentioned above, Properties-History saves a new entry every time the value of a Property from a Thing has changed.

The following example shows the syntax of a history entry in the API:

{
  "at": "2023-06-15T16:49:00Z",
  "properties": {
    "memory": 27,
    "cpu": 44
  }
}

Also, multiple timestamps can be indicated, as seen in the following example:

[
  {
    "at": "2023-06-15T16:49:00Z",
    "properties": {
      "cpu": 43,
      "memory": 27,
      "disk": 19
    }
  },
  {
    "at": "2023-06-15T16:54:00Z",
    "properties": {
      "cpu": 87,
      "memory": 69
    }
  },
  {
    "at": "2023-06-15T16:59:00Z",
    "properties": {
      "disk": 17
    }
  }
]
