Statistics

This call queries the Ably REST /stats API endpoint and retrieves your application’s usage statistics. A PaginatedResult is returned, containing an array of Stats for the first page of results. PaginatedResult objects are iterable providing a means to page through historical statistics. See an example set of raw stats returned via the REST API.

Parameters

options

an optional object containing the query parameters

callback

is a function of the form: function(err, result)

options parameters

The following options, as defined in the REST /stats API endpoint, are permitted:

start

beginning of time earliest time in milliseconds since the epoch for any stats retrievedType: Long

end

current time latest time in milliseconds since the epoch for any stats retrievedType: Long

direction

backwards forwards or backwardsType: String

limit

100 maximum number of messages to retrieve up to 1,000Type: Integer

unit

minute minute, hour, day or month. Based on the unit selected, the given start or end times are rounded down to the start of the relevant interval depending on the unit granularity of the queryType: String

A Stats object represents an application’s statistics for the specified interval and time period. Ably aggregates statistics globally for all accounts and applications, and makes these available both through our statistics API as well as your application dashboard.

Please note that most attributes of the Stats type below contain references to further stats types. This documentation is not exhaustive for all stats types, and as such, links to the stats types below will take you to the Ruby library stats documentation which contains exhaustive stats documentation. Ruby and Python however uses under_score case instead of the default camelCase in most languages, so please bear that in mind.

Properties

unit

the length of the interval that this statistic covers, such as 'minute', 'hour', 'day', 'month'.Type: String

intervalId

the UTC time at which the time period covered by this Stats object starts. For example, an interval ID value of “2018-03-01:10″ in a Stats object whose unit is day would indicate that the period covered is “2018-03-01:10 .. 2018-03-01:11″. All Stats objects, except those whose unit is minute, have an interval ID with resolution of one hour and the time period covered will always begin and end at a UTC hour boundary. For this reason it is not possible to infer the unit by looking at the resolution of the intervalId. Stats objects covering an individual minute will have an interval ID indicating that time; for example “2018-03-01:10:02″.Type: String

all

aggregate count of both inbound and outbound message statsType: MessageTypes

apiRequests

breakdown of API requests received via the Ably REST APIType: RequestCount

channels

breakdown of channel related stats such as min, mean and peak channelsType: ResourceCount

connections

breakdown of connection related stats such as min, mean and peak connections for TLS and non-TLS connectionsType: ConnectionTypes

inbound

statistics such as count and data for all inbound messages received over REST and Realtime connections, organized into normal channel messages or presence messagesType: MessageTraffic

outbound

statistics such as count and data for all outbound messages retrieved via REST history requests, received over Realtime connections, or pushed with Webhooks, organized into normal channel messages or presence messagesType: MessageTraffic

persisted

messages persisted and later retrieved via the history APIType: MessageTypes

tokenRequests

breakdown of Ably Token requests received via the Ably REST API.Type: RequestCount
