This class wraps microsoft/application-insights package allowing to configure it according to the current needs.

It was created to simplify app-insights-php/app-insights-php-bundle implementation.

$client = new AppInsightsPHP\Client\Factory(
    'your_instrumentation_key', 
    AppInsightsPHP\Client\Configuration::createDefault()
);

$client->trackMessage(...);
$client->trackRequest(...);
// ... all methods available by source package

Size of the telemetry is limited to 64 kilobytes. Before trying to send anything to AppInsights a telemetry is validated against that requirement. If it exceeds the limit exception is thrown. To avoid that exception you should first check if the given data are not too big. You can use TelemetryData::exceededMaximumSize() do it for you.
