Online Monitor

$ python -m larpixdaq.online_monitor --help
usage: online_monitor.py [-h] [--core CORE] [--log-address LOG_ADDRESS]

Launch the data consumer providing the online data monitor

optional arguments:
  -h, --help            show this help message and exit
  --core CORE           The address of the DAQ Core, not including port number
  --log-address LOG_ADDRESS
                        Address to connect to global log, including port
                        number

class larpixdaq.online_monitor.OnlineMonitor(core_address, log_address)

Record packets from the current run and compute various statistics.

Run data provides the online data monitor for the LArPix DAQ. It tracks the packet rate and can send packets for manual inspection. It also tracks each pixel’s recent and max data rate as well as an ADC histogram.

Parameters

• core_address – the full TCP address (including port number) that data will be published to

• log_address – the full TCP address (including port number) of the DAQ Log

handle_new_message(origin, header, message)

Store new info messages.

handle_new_data(origin, header, data)

Store new data packets and save data rate and ADCs.

maybe_send_update(*args)

Send an update to the webserver once per second.

Parameters

args – ignored

send_message_update(*args)

Send an update containing info messages.

Parameters

args – ignored

create_pixel_lookup(chip_pixel_list)

Create a pixel lookup from a given list of chip-pixel assignments.

chip_pixel_list is of the form:

[
  [chip0id, [ch0pixel, ch1pixel, ...]],
  [chip1id, [ch0pixel, ch1pixel, ...]],
  ...
]

create_chip_lookup(chip_pixel_list)

Create a chip+channel lookup based on pixel ID.

The input chip_pixel_list is of the form:

[
  [chip0id, [ch0pixel, ch1pixel, ...]],
  [chip1id, [ch0pixel, ch1pixel, ...]],
  ...
]

The output is of the form:

{
  pixel0id: {'channel': pixel0channel, 'chip': pixel0chip},
  pixel1id: {'channel': pixel1channel, 'chip': pixel1chip},
  ...
}

retrieve_pixel_layout()

Return the current pixel layout and pixel->{chip, channel} mapping.

load_pixel_layout(name)

Retrieve and store the pixel layout from larpix-geometry.
