Sending telemetric data to DCM #14
Description
Sending telemetric data to DCM (or any other backend) could provide better traceability of random device reboots etc.
If desired, i can make a backend that can retrieve that data and generate graphs for each device and parameter.
int sendTelemetricData (void)
{
// Device name
NSString *deviceName = [[UIDevice currentDevice] name];
// Battery percentage
UIDevice *device = [UIDevice currentDevice];
device.batteryMonitoringEnabled = YES;
float batteryLevel = [device batteryLevel] * 100.0f;
// CPU temperature
int mib[2];
mib[0] = CTL_HW;
mib[1] = HW_CPU_TEMPERATURE;
int64_t temperature;
size_t length = sizeof(temperature);
sysctl(mib, 2, &temperature, &length, NULL, 0);
float cpuTemp = temperature / 100.0f;
// Init
CURL *curl;
CURLcode res;
curl_global_init(CURL_GLOBAL_ALL);
curl = curl_easy_init();
if (curl)
{
curl_easy_setopt(curl, CURLOPT_URL, "http://YOUR_DCM_URL");
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "device_name=%f&battery_percentage=%f&cpu_temperature=%f", [deviceName UTF8String], batteryLevel, cpuTemp);
res = curl_easy_perform(curl);
if (res != CURLE_OK) {
fprintf(stderr, "dmon: curl_easy_perform() failed: %s\n", curl_easy_strerror(res));
}
curl_easy_cleanup(curl);
}
curl_global_cleanup();
return 0;
