Detailed Description

Use QInsightConfiguration to configure the tracker. The tracker reads initial values from a configuration file (qtinsight.conf), which is searched from following the locations in a decending order:

  1. Application's resources file.
  2. Application's directory.
  3. Current working directory.
  4. System configuration directories as defined by QStandardPaths::GenericConfigLocation.

Use an environment variable QT_INSIGHT_CONFIG to override the used configuration file.

Example of a JSON configuration file:

{
    "server" : "collect-insight.qt.io",
    "token" : "00000000-0000-0000-0000-000000000000",
    "device_model" :  "model 1",
    "device_variant" : "a",
    "device_screen_type" : "NON_TOUCH",
    "platform" : "app",
    "app_build" : "1.2.3",
    "storage" : "SQLITE",
    "storage_path" : "",
    "storage_size" : 0,
    "sync" : {
        "interval" : {
            "seconds" : 0
            "minutes" : 0
            "hours" : 1
            "days" : 0
            "months" : 0
        },
        "max_batch_size" : 100
    },
    "config_sync" : {
        "enabled" : true
        "interval" : {
            "seconds" : 0
            "minutes" : 0
            "hours" : 0
            "days" : 1
            "months" : 0
        },
    },
    "categories" : [
        "debug"
    ],
    "events" : [
        "KeyPress",
        "KeyRelease",
        "MouseButtonPress",
        "MouseButtonRelease",
        "Quit",
        "Resize"
    ]
}

A token is used to match the data your application sends to your Qt Insight Organization and you can find your token from the Qt Insight Console.

Some of the configuration items are directly linked to the Snowblow Tracker Protocol, which defines the allowed values. These include QInsightConfiguration::setPlatform() and QInsightConfiguration::setDeviceScreenType().

QInsightConfiguration::setStorageType() can be used to configure the storage type, where SQLITE is the default value and use SQLite database to store the events before they are sent to the back-end server. If an unknown storage type is specified or it is explicitly set to an empty string, caching will be disabled. In that case the tracked data will be lost if the back-end server isn't available.

Two additional storage types are supported: SQLITE-ZLIB and SQLITE-ZSTD. These provide sqlite storage but compress the event data to save disk space. Both zlib and zstd algorithms are used with a dictionary-based compression where the dictionary is created from the first collected events. In general, zstd offers faster compression with higher compression ratio, but requires more memory to train the dictionary.

QInsightConfiguration::setStoragePath() can be used to configure the location of the storage. By default, the SQLite database is created in the application's directory.

QInsightConfiguration::setStorageSize() can be used to limit the number of events that can be cached. When using SQLITE storage type, the oldest events are removed if storage size is exceeded. The default size (0) sets no limits to the storage size.

QInsightConfiguration::setSyncInterval() can be used to configure how often the tracked events are sent to the back-end server. The API takes the value in seconds, while the json configuration file can be configured also with minutes, hours, days, and months. If sync interval is not set, events will never be sent to the backend and cached only in the local storage.

QInsightConfiguration::setBatchSize() is used to minimize the overhead when sending, reading and writing to the storage. When synchronizing the cached data to back-end server, at most QInsightConfiguration::batchSize() items will be fetched at once from the storage and sent to back-end server. This is more optimal, than fetching the data one by one. The sent data will be removed from the storage also in batches. The process repeats, until all data is sent. If one batch fails, the synchronization will stop, as the next batches will likely also fail.

QInsightConfiguration::setRemoteConfig and QInsightConfiguration::setRemoteConfigInterval() can be used to enable the use of remote configurations and configure how often the remote configurations are synced from the back-end server. The API takes the value in seconds, while the json configuration file can be configured also with minutes, hours, days, and months. If QInsightConfiguration::setRemoteConfigInterval() is not set, the interval from QInsightConfiguration::SyncInterval() is used.

QInsightConfiguration::setCategories() allows filtering of tracked events based on the category used in the API calls for QInsightTracker::interaction() and QInsightTracker::transition() events or the attached property InsightCategory::category for the automatic QEvent::type events.

QInsightConfiguration::setEvents() can be used to enable tracking of automatic events from Qt's event system. All valid event types in QEvent::Type can be used.
