ubuntu check if server is running code example

Example 1: check if mongodb is running mac

ps -ef | grep mongod | grep -v grep | wc -l | tr -d ' '

Example 2: check if service is running android

Create the method:

private boolean isMyServiceRunning(Class<?> serviceClass) {
    ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
    for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
        if (serviceClass.getName().equals(service.service.getClassName())) {
            return true;
        }
    }
    return false;
}

And I call it using:
isMyServiceRunning(MyService.class)
