MozNetworkStatsManager.getSamples()

This API is available on Firefox OS for internal applications only.

Summary

The getSamples method asynchronously queries network interface statistics. The query may be filtered by connection type and date.

A data usage chunk is a MozNetworkStatsData object representing the total amount of bits received and sent during the amount of time defined by the sampleRate property.

Syntax

var samples = getSamples(network, start, end, options);

samples.onsuccess = function() {
  // do something with samples.result
}

Parameters

network: The origin of the data; it can be specified as wifi or mobile. If null, data measurement from both origins are merged. To know in advance which kind of origin is available, the MozNetworkStatsManager.getAvailableNetworks method returns an Array of interfaces.
start: A Date object representing the beginning of data measurement.
end: A Date object representing the end of data measurement.
options Optional: Filtering options.; NetworkStatsGetOptions is a dictionary object providing filtering options.

Return

A DOMRequest object. If successful, the request result is a MozNetworkStats object describing the network statistics. If network stats are not available for some dates, then rxBytes and txBytes are undefined for those dates. If the filtering start date is greater than the end date, an exception is thrown.

Exceptions

NS_ERROR_INVALID_ARG: The filtering start date is greater than the end date.
NS_ERROR_NOT_IMPLMENTED: Both appManifestURL and serviceType are specified at the same time in the NetworkStatsGetOptions dictionary.
InvalidNetwork: The network must be in the return of MozNetworkStatsManager.getAvailableNetworks.
