Users' media usage statistics

Returns information about all local media usage of users. Gives the possibility to filter them by time and user.

To use it, you will need to authenticate by providing an access_token for a server admin: see Admin API.

The API is:

GET /_synapse/admin/v1/statistics/users/media

A response body like the following is returned:

{
  "users": [
    {
      "displayname": "foo_user_0",
      "media_count": 2,
      "media_length": 134,
      "user_id": "@foo_user_0:test"
    },
    {
      "displayname": "foo_user_1",
      "media_count": 2,
      "media_length": 134,
      "user_id": "@foo_user_1:test"
    }
  ],
  "next_token": 3,
  "total": 10
}

To paginate, check for next_token and if present, call the endpoint again with from set to the value of next_token. This will return a new page.

If the endpoint does not return a next_token then there are no more reports to paginate through.

Parameters

The following parameters should be set in the URL:

• limit: string representing a positive integer - Is optional but is used for pagination, denoting the maximum number of items to return in this call. Defaults to 100.
• from: string representing a positive integer - Is optional but used for pagination, denoting the offset in the returned results. This should be treated as an opaque value and not explicitly set to anything other than the return value of next_token from a previous call. Defaults to 0.
• order_by - string - The method in which to sort the returned list of users. Valid values are:
  • user_id - Users are ordered alphabetically by user_id. This is the default.
  • displayname - Users are ordered alphabetically by displayname.
  • media_length - Users are ordered by the total size of uploaded media in bytes. Smallest to largest.
  • media_count - Users are ordered by number of uploaded media. Smallest to largest.
• from_ts - string representing a positive integer - Considers only files created at this timestamp or later. Unix timestamp in ms.
• until_ts - string representing a positive integer - Considers only files created at this timestamp or earlier. Unix timestamp in ms.
• search_term - string - Filter users by their user ID localpart or displayname. The search term can be found in any part of the string. Defaults to no filtering.
• dir - string - Direction of order. Either f for forwards or b for backwards. Setting this value to b will reverse the above sort order. Defaults to f.

Response

The following fields are returned in the JSON response body:

• users - An array of objects, each containing information about the user and their local media. Objects contain the following fields:
  • displayname - string - Displayname of this user.
  • media_count - integer - Number of uploaded media by this user.
  • media_length - integer - Size of uploaded media in bytes by this user.
  • user_id - string - Fully-qualified user ID (ex. @user:server.com).
• next_token - integer - Opaque value used for pagination. See above.
• total - integer - Total number of users after filtering.

Get largest rooms by size in database

Returns the 10 largest rooms and an estimate of how much space in the database they are taking.

This does not include the size of any associated media associated with the room.

Returns an error on SQLite.

Note: This uses the planner statistics from PostgreSQL to do the estimates, which means that the returned information can vary widely from reality. However, it should be enough to get a rough idea of where database disk space is going.

The API is:

GET /_synapse/admin/v1/statistics/database/rooms

A response body like the following is returned:

{
  "rooms": [
    {
      "room_id": "!OGEhHVWSdvArJzumhm:matrix.org",
      "estimated_size": 47325417353
    }
  ],
}

Response

The following fields are returned in the JSON response body:

• rooms - An array of objects, sorted by largest room first. Objects contain the following fields:
  • room_id - string - The room ID.
  • estimated_size - integer - Estimated disk space used in bytes by the room in the database.
