Crate glean[−][src]

Expand description

Glean is a modern approach for recording and sending Telemetry data.

It’s in use at Mozilla.

All documentation can be found online:

Example

Initialize Glean, register a ping and then send it.

let cfg = Configuration {
    data_path: "/tmp/data".into(),
    application_id: "org.mozilla.glean_core.example".into(),
    upload_enabled: true,
    max_events: None,
    delay_ping_lifetime_io: false,
    channel: None,
    server_endpoint: None,
    uploader: None,
    use_core_mps: false,
};
glean::initialize(cfg, ClientInfoMetrics::unknown());

let prototype_ping = PingType::new("prototype", true, true, vec!());

glean::register_ping_type(&prototype_ping);

prototype_ping.submit(None);

Modules

net

Handling the Glean upload logic.

private

The different metric types supported by the Glean SDK to handle data.

traits

API definitions for the different metric types supported by the Glean SDK.

Structs

ClientInfoMetrics

Metrics included in every ping as client_info.

CommonMetricData

The common set of data shared across all different metric types.

Configuration

The Glean configuration.

DistributionData

A snapshot of all buckets and the accumulated sum of a distribution.

Error

A specialized Error type for this crate’s operations.

Glean

The object holding meta information about a Glean instance.

RecordedEvent

Represents the recorded data for a single event.

The possible error types for metric recording. Note: the cases in this enum must be kept in sync with the ones in the platform-specific code (e.g. ErrorType.kt) and with the metrics in the registry files.

HistogramType

Different kinds of histograms.

Lifetime

The supported metrics’ lifetimes.

MemoryUnit

Different resolutions supported by the memory related metric types (e.g. MemoryDistributionMetric).

TimeUnit

Different resolutions supported by the time related metric types (e.g. DatetimeMetric).

Functions

get_timestamp_ms

Returns a timestamp corresponding to “now” with millisecond precision.

handle_client_active

Performs the collection/cleanup operations required by becoming active.

handle_client_inactive

Performs the collection/cleanup operations required by becoming inactive.

initialize

Creates and initializes a new Glean object.

persist_ping_lifetime_data

Dispatches a request to the database to persist ping-lifetime data to disk.

register_ping_type

Register a new PingType.

rlb_flush_dispatcher

Unblock the global dispatcher to start processing queued tasks.

set_debug_view_tag

Sets a debug view tag.

set_experiment_active

Indicate that an experiment is running. Glean will then add an experiment annotation to the environment which is sent with pings. This infomration is not persisted between runs.

set_experiment_inactive

Indicate that an experiment is no longer running.

set_log_pings

Sets the log pings debug option.

set_source_tags

Sets source tags.

set_upload_enabled

Sets whether upload is enabled or not.

shutdown

Shuts down Glean in an orderly fashion.

submit_ping_by_name

Collects and submits a ping for eventual uploading by name.
