SystemLogger

SystemLogger node is used to get system information of the device.

How to place it

Python

C++

pipeline = dai.Pipeline()
logger = pipeline.create(dai.node.SystemLogger)

dai::Pipeline pipeline;
auto logger = pipeline.create<dai::node::SystemLogger>();

Message types

Usage

Python

C++

pipeline = dai.Pipeline()
logger = pipeline.create(dai.node.SystemLogger)
logger.setRate(1)  # 1 Hz

# Send system info to the host via XLink
xout = pipeline.create(dai.node.XLinkOut)
xout.setStreamName("sysinfo")
logger.out.link(xout.input)

dai::Pipeline pipeline;
auto logger = pipeline.create<dai::node::SystemLogger>();\
logger->setRate(1.0f);  // 1 Hz

// Send system info to the host via XLink
auto xout = pipeline.create<dai::node::XLinkOut>();
xout->setStreamName("sysinfo");
logger->out.link(xout->input);

Public Functions

SystemLogger(const std::shared_ptr<PipelineImpl> &par, int64_t nodeId)
SystemLogger(const std::shared_ptr<PipelineImpl> &par, int64_t nodeId, std::unique_ptr<Properties> props)
void setRate(float hz)

Specify logging rate, at which messages will be sent out

Parameters

  • hz: Sending rate in hertz (messages per second)

float getRate()

Gets logging rate, at which messages will be sent out

Public Members

Output out = {*this, "out", Output::Type::MSender, {{DatatypeEnum::SystemInformation, false}}}

Outputs SystemInformation message that carries various system information like memory and CPU usage, temperatures, …
