Statistics

The Ably service retains usage statistics per application and per account at 1 minute intervals. Your application statistics are available programmatically through our client libraries at 1 minute intervals, or aggregated up to the hour, day, or month.

Your most recent statistics are delayed by up to 6 seconds.

Your application and account statistics are also available as graphs, tabular data or downloads in your application dashboard.

The Ably service aggregates your application statistics by minute, hour, day and month, both at an application level and at an account level. Account level statistics are not available via the client library APIs and must be viewed using your account dashboard. Your monthly quota and any potential overages are calculated using the account level statistics. Find out what happens if you exceed your package limits.

Getting started

The Ably Realtime client library provides a straightforward API for retrieving application statistics:

var realtime = new Ably.Realtime('xVLyHw.EjrQWw:OWETynsJvYDFIZtI');
realtime.stats({ unit: 'hour' }, function(err, resultPage) {
  var thisHour = resultPage.items[0];
  console.log(thisHour); // => {all: a, inbound: f, outbound: f, …}
});

var realtime = new Ably.Realtime('xVLyHw.EjrQWw:OWETynsJvYDFIZtI');
realtime.stats({ unit: 'hour' }, function(err, resultPage) {
  var thisHour = resultPage.items[0];
  console.log(thisHour); // => {all: a, inbound: f, outbound: f, …}
});

realtime = Ably::Realtime.new('xVLyHw.EjrQWw:OWETynsJvYDFIZtI')
realtime.stats(unit: 'hour') do |result_page|
  this_hour = result_page.items.first
  puts this_hour # => #<Ably::Models::Stat:…
end

AblyRealtime realtime = new AblyRealtime("xVLyHw.EjrQWw:OWETynsJvYDFIZtI");
Params options = new Param[]{ new Param("unit", "hour") }
PaginatedResult<Stats> results = realtime.stats(options);
Stats thisHour = results.items[0];
System.out.println("Published this hour " + thisHour.inbound.all.all.count);

AblyRealtime realtime = new AblyRealtime("xVLyHw.EjrQWw:OWETynsJvYDFIZtI");
StatsRequestParams query = new StatsRequestParams() { Unit = StatsIntervalGranularity.Hour };
PaginatedResult<Stats> results = await realtime.StatsAsync(query);
Stats thisHour = results.Items[0];
Console.WriteLine("Published this hour " + thisHour.Inbound.All.All);

ARTRealtime *realtime = [[ARTRealtime alloc] initWithKey:@"xVLyHw.EjrQWw:OWETynsJvYDFIZtI"];
ARTStatsQuery *query = [[ARTStatsQuery alloc] init];
query.unit = ARTStatsGranularityHour;
[realtime stats:query callback:^(ARTPaginatedResult<ARTStats *> *result, ARTErrorInfo *error) {
    ARTStats *thisHour = result.items[0];
    NSLog(@"Published this hour %lu", thisHour.inbound.all.all.count);
} error:nil];

let realtime = ARTRealtime(key: "xVLyHw.EjrQWw:OWETynsJvYDFIZtI")
let query = ARTStatsQuery()
query.unit = .Hour
try! realtime.stats(query) { results, error in
    let thisHour = results!.items[0]
    print("Published this hour \(thisHour.inbound.all.all.count)")
}

Note that all examples on this page assume you are running them within an EventMachine reactor. Find out more in our Realtime usage documentation.

Realtime API Reference

stats

stats(Object options, callback(ErrorInfo err, PaginatedResult<Stats> results))Deferrable stats(Hash options) → yields PaginatedResult<Stats>PaginatedResult<Stats> stats(Param[] options)stats(query: ARTStatsQuery?, callback: (ARTPaginatedResult<ARTStats>?, ARTErrorInfo?) → Void) throwsTask<PaginatedResult<Stats>> StatsAsync(StatsRequestParams query)

This call queries the REST /stats API 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

callback

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

Stats objectARTStatsio.ably.lib.types.StatsAbly::Models::StatsIO.Ably.Stats

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.

PropertiesMembersAttributesKeyword arguments

unit

the length of the interval that this statistic covers, such as :minute, :hour, :day, :monthMinute, Hour, Day, MonthStatGranularityDay, StatGranularityMonth'minute', 'hour', 'day', 'month'.
Type: Stats::GRANULARITYStatsIntervalGranularity enumARTStatsGranularityString

interval_granularityintervalGranularity

Deprecated alias for unit; scheduled to be removed in version 2.x client library versions.
Type: Stats::GRANULARITYStatsIntervalGranularity enumARTStatsGranularityString

intervalIdinterval_idIntervalId

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”.
