Reference Information
Napatech Software Suite: Sensors

Each adapter type is equipped with a number of adapter sensors and port sensors.
The number of sensors is different for each adapter type.
The sensors are divided into 3 groups:

  • Public sensors
    These sensors can be read using the monitor tool and the diagnostic tool. They are important for the health of the adapter and will trigger a sensor event and log a message if they are out of range. The sensors can also be read using the info stream NT_InfoRead (described later).
  • Level 1 sensors
    These sensors can be read using the monitor tool and the diagnostic tool. They are information sensors and will not trigger events or log messages. The sensors can also be read using the info stream NT_InfoRead (described later).
  • Level 2 sensors
    These sensors are Napatech internal sensors and are used for debugging and troubleshooting. They are included in a support info dump.
    Reading the Sensors using Tools
    The sensors can be read by the following tools:
  • monitoring (public and level 1 sensors)
  • diagnostic (public and level 1 sensors)
  • support info (all sensors)

    Reading the Sensors using Info Stream
    The sensors can also be read by using the info stream NT_InfoRead. Only public sensors and
    level 1 sensors can be read by the info stream. This chapter will only explain how to set up
    the NtInfo_s info structure. How to access the stream will not be handled here.

    Reading Multiple Sensors

Reading the Number of Adapter Sensors

NtInfo_t infoAdapter;
int sensorCounter0;
int sensorCounter1;
infoAdapter.cmd = NT_INFO_CMD_READ_ADAPTER;
infoAdapter.u.adapter.adapterNo = 0;
if ((status = NT_InfoRead(hInfo, &infoAdapter)) != NT_SUCCESS) {
NT_ExplainError(status, errBuf, sizeof(errBuf));
fprintf(stderr, ">>> Error: NT_InfoRead failed. Code %d = %s\n", status, errBuf);
goto ErrorExit;
}
sensorCounter0 = infoAdapter.u.adapter.data.numSensors;
sensorCounter1 = infoAdapter.u.adapter.data.numLevel1Sensors;

Reading the Public Adapter Sensors

int teller;
int32_t value;
NtInfo_t infoSensor;
for (teller = 0; teller < sensorCounter; teller++)
{
infoSensor.u.sensor.sourceIndex = 0; // get sensors from adapter 0
infoSensor.u.sensor.sensorIndex = teller;
status = NT_InfoRead(hInfo, &infoSensor);
if (status == NT_SUCCESS) {
value = infoSensor.u.sensor.data.value; // Sensor data is returned in the infoSensor.u.sensor.data struct
}
else {
NT_ExplainError(status, errBuf, sizeof(errBuf));
fprintf(stderr, ">>> Error: NT_InfoRead failed. Code %d = %s\n", status, errBuf);
goto ErrorExit;
}
}

Reading the Number of Port Sensors

NtInfo_t infoPort;
int sensorCounter0;
int sensorCounter1;
infoPort.cmd = NT_INFO_CMD_READ_PORT;
infoPort.u.port.portNo = 2; // Read info from port 2
if ((status = NT_InfoRead(hInfo, &infoPort)) != NT_SUCCESS) {
NT_ExplainError(status, errBuf, sizeof(errBuf));
fprintf(stderr, ">>> Error: NT_InfoRead failed. Code %d = %s\n", status, errBuf);
goto ErrorExit;
}
sensorCounter0 = infoPort.u.port.data.numSensors;
sensorCounter1 = infoPort.u.port.data.numLevel1Sensors;

Reading the Public Port Sensors

int teller;
int32_t value;
NtInfo_t infoSensor;
for (teller = 0; teller < sensorCounter; teller++)
{
infoSensor.u.sensor.sourceIndex = 2; // get sensors from port 2
infoSensor.u.sensor.sensorIndex = teller;
status = NT_InfoRead(hInfo, &infoSensor);
if (status == NT_SUCCESS) {
value = infoSensor.u.sensor.data.value; // Sensor data is returned in the infoSensor.u.sensor.data struct
}
else {
NT_ExplainError(status, errBuf, sizeof(errBuf));
fprintf(stderr, ">>> Error: NT_InfoRead failed. Code %d = %s\n", status, errBuf);
goto ErrorExit;
}
}

Reading a Single Sensor

The sensors are divided into groups. Each adapter type has an adapter sensor group and
a port sensor group. The sensor group is different for each adapter type. When reading a sensor,
the sensor source, source index (the adapter number or port number) and the sensor index in
the sensor group must be selected.

Reading a Single Sensor from an NT20E2 Adapter
In order to read a single sensor from an adapter or port, the type of adapter must be known.
The sensor index must be selected from the adapter type sensor group.

int32_t value;
NtInfo_t infoSensor;
infoSensor.u.sensor.source = NT_SENSOR_SOURCE_ADAPTER; // The source must be adapter
infoSensor.u.sensor.sourceIndex = 0; // The adapter is adapter 0
infoSensor.u.sensor.sensorIndex = NT_SENSOR_NT20E2_FPGA; // Read FPGA temperature
// The index in the NT20E2 adapter sensor group
status = NT_InfoRead(hInfo, &infoSensor);
if (status == NT_SUCCESS) {
value = infoSensor.u.sensor.data.value; // Sensor data is returned in the infoSensor.u.sensor.data struct
}
else {
NT_ExplainError(status, errBuf, sizeof(errBuf));
fprintf(stderr, ">>> Error: NT_InfoRead failed. Code %d = %s\n", status, errBuf);
goto ErrorExit;
}

See the sensor example for a complete code example sensor/sensor_example.c

Sensor Events

When a sensor reaches a value that is out of the sensor range, a sensor event (alarm)
is triggered. In order to receive sensor events (alarms), the event stream must be
opened and polled. See the event example event/event_example.c for how to do this.
The sensor information is stored in NtEventSensor_s.

NtEvent_t hEvent;
if((status = NT_EventRead(hEventStream, &hEvent, 10000)) != NT_SUCCESS) {
// Get the status code as text
fprintf(stderr, "NT_EventRead() failed: %s\n", errorBuffer);
return -1;
}
// check event info
// The event sensor info
hEvent.u.sensorEvent.source // Adapter or port sensor
hEvent.u.sensorEvent.sourceIndex // The adapter or port number
hEvent.u.sensorEvent.sensorIndex // The index in the sensor group
// Note: The index depends on whether
// it is a port or adapter source and
// the type of adapter
hEvent.u.sensorEvent.adapterType // The type of the adapter
hEvent.u.sensorEvent.action // Enter or leaving alarm state
hEvent.u.sensorEvent.value // Value that triggered the event
}
else {
// Another type of event
}

Identifying an Event
In order to identify an event, the source, sensorIndex and adapterType must be used.
The sourceIndex identifies the adapter or port that has the alarm.

Sensor Alarms in the Log

When a sensor alarm is triggered, a message is written in the log.
The message could be for adapter sensors:
Adapter sensor "SensorIndex" "Sensor name" on adapter "sourceIndex": enter alarm state with value XX
And for port sensors:
Port sensor "SensorIndex" "Sensor name" on port "sourceIndex": enter alarm state with value XX
The sourceIndex is either the adapter number or port number depending on the source.
The sensorIndex is the index in the sensor group. See the sensor groups above.
The sensor name for each sensor can be found by reading the sensor information using the info stream.
The current value is the value triggering the sensor alarm. The range for each sensor can be found
by reading the sensor information.

Changing the Limits for a Sensor

It is possible to change to upper and lower limit of a sensor and thereby reduce the range where
the sensor can operate without triggering a warning. The limits can be changed by using the config tool
or the config stream.

Setting the Limits using the Config Stream
In order to set the limits using the config stream, the available sensors must first be read using the
info stream.

NtInfo_t infoAdapter;
NtInfo_t infoSensor;
uint32_t sensor;
// Get the number of sensors for adapter 1
infoAdapter.cmd = NT_INFO_CMD_READ_ADAPTER;
infoAdapter.u.adapter.adapterNo = 1;
if ((status = NT_InfoRead(hInfo, &infoAdapter)) != NT_SUCCESS) {
NT_ExplainError(status, errBuf, sizeof(errBuf));
fprintf(stderr, ">>> Error: NT_InfoRead failed. Code %d = %s\n", status, errBuf);
return status;
}
for (sensor = 0; sensor < infoAdapter.u.adapter.data.numSensors; sensor++) {
infoSensor.u.sensor.source = NT_SENSOR_SOURCE_ADAPTER; // Select to source to be adapter sensors
infoSensor.u.sensor.sourceIndex = 1; // Adapter 1
infoSensor.u.sensor.sensorIndex = sensor; // Sensor number/index
status = NT_InfoRead(hInfo, &infoSensor);
if (status == NT_SUCCESS) {
// The sensor values returned
infoSensor.u.sensor.data.limitLow
infoSensor.u.sensor.data.limitHigh
infoSensor.u.sensor.data.value
infoSensor.u.sensor.data.name
infoSensor.u.sensor.data.type
}
}

Then the limits can be written to the desired sensor.

NtConfig_t configInfo;
configInfo.parm = NT_CONFIG_PARM_SENSOR; // The config sensor command
configInfo.u.write.sensor.sensorIndex = sensor; // The sensor number/index to change
configInfo.u.write.sensor.sourceIndex = 1; // Adapter 1
configInfo.u.write.sensor.source = NT_SENSOR_SOURCE_ADAPTER; // Select source to be adapter sensors
configInfo.u.write.sensor.data.limitHigh = sensorHigh; // Upper sensor limit
configInfo.u.write.sensor.data.limitLow = sensorLow; // Lower sensor limit
if ((status = NT_ConfigWrite(hConfig, &configInfo)) != 0) {
NT_ExplainError(status, errBuf, sizeof(errBuf));
fprintf(stderr, ">>> Error: NT_ConfigWrite failed. Code %d = %s\n", status, errBuf);
goto ErrorExit;
}

Note: It is not possible to set any limits outside the factory default range, that is, it is
not possible to select a higher upper limit or a lower lower limit than the factory default.
Reset the Limits to Factory Default
By setting limitLow=0 and limitHigh=0 the limits are reset to factory default.
