How to get service status and indications
Please follow below steps to request service status and indication
1. Implement IServingSystemListener listener class
class ServingSystemListener : public telux::data::IServingSystemListener {
public:
ServingSystemListener(SlotId slotId) : slotId_(slotId) {}
void onServiceStateChanged(telux::data::ServiceStatus status) {
std::cout << "\n onServiceStateChanged on SlotId: " << static_cast<int>(slotId_);
if(status.serviceState == telux::data::DataServiceState::OUT_OF_SERVICE) {
std::cout << "Current Status is Out Of Service" << std::endl;
} else {
std::cout << "Current Status is In Service" << std::endl;
}
}
private:
SlotId slotId_;
};
2. Instantiate initialization callback - this is optional
auto initCb = [&](telux::common::ServiceStatus status) {
subSystemStatus = status;
subSystemStatusUpdated = true;
cv_.notify_all();
};
3. Get the DataFactory and data Serving System Manager instance
auto &dataFactory = telux::data::DataFactory::getInstance();
do {
subSystemStatusUpdated = false;
std::unique_lock<std::mutex> lck(mtx_);
dataServingSystemMgr = dataFactory.getServingSystemManager(slotId, initCb);
4. Check if data serving system manager is ready
if (dataServingSystemMgr) {
std::cout << "\n\nInitializing Data Serving System manager subsystem on slot " <<
slotId << ", Please wait ..." << std::endl;
cv_.wait(lck, [&]{return subSystemStatusUpdated;});
subSystemStatus = dataServingSystemMgr->getServiceStatus();
}
if (subSystemStatus == telux::common::ServiceStatus::SERVICE_AVAILABLE) {
std::cout << " *** DATA Serving System is Ready *** " << std::endl;
break;
}
else {
std::cout << " *** Unable to initialize data Serving System *** " << std::endl;
}
} while (1);
5. Register for Serving System listener
dataServingSystemMgr->registerListener(dataListener);
6. Get current Service Status
auto respCb = [&slotId](
telux::data::ServiceStatus serviceStatus, telux::common::ErrorCode error) {
std::cout << std::endl << std::endl;
std::cout << "CALLBACK: "
<< "requestServiceStatus Response on slotid " << static_cast<int>(slotId);
if(error == telux::common::ErrorCode::SUCCESS) {
std::cout << " is successful" << std::endl;
logServiceStatusDetails(serviceStatus);
}
else {
std::cout << " failed"
<< ". ErrorCode: " << static_cast<int>(error) << std::endl;
}
};
dataServingSystemMgr->requestServiceStatus(respCb);
7. Wait for request response and notifications
