Check status of Devices Attributes¶

import fandango as fn
import fandango.tango as ft

At server level¶

This code allows to visualize the state of all servers matching a regular expression

astor = fn.Astor('PyAttributeProcessor/*')
astor.states()

('pyattributeprocessor/sr_ct_calc', PyTango._PyTango.DevState.ON)
('pyattributeprocessor/test_acc', PyTango._PyTango.DevState.ON)
('pyattributeprocessor/lab01_di_fft01', None)
('pyattributeprocessor/linacwatcher', PyTango._PyTango.DevState.ON)
('pyattributeprocessor/sr_calc', PyTango._PyTango.DevState.ON)

At device level¶

devices = astor.get_all_devices()

OR

devices = fn.get_matching_devices('SR/CT/*')

THEN

[(d,ft.check_device(d)) for d in devices]

('sr/ct/calc-01', True)
('sr/ct/calc-02', True)
('test/acc/calc', True)
('archiving/watcher/linac', None)
('sr/di/calc', True)

At attribute level¶

d = 'sr/di/calc'

[(d,a,ft.read_attribute(a)) for a in fn.get_matching_attributes(d+'/*')]

('sr/di/calc', 'sr/di/calc/Gamma', 5832.0)
('sr/di/calc', 'sr/di/calc/Alpha', 0.00096000000000000002)
('sr/di/calc', 'sr/di/calc/MeasProduct', 2799.8000000000002)

From Unix Shell¶

Using fandango.sh:

for attr in $(fandango.sh get_matching_attributes "sr/di/calc/*Coup*"); do
   echo "$attr : $(fandango.sh read_attribute ${attr})" ;
   done

sr/di/calc/SimulatorCoupling : 0.6
sr/di/calc/UserDefCoupling : 0.6
sr/di/calc/Coupling : 0.0
sr/di/calc/SetMachineCoupling : False
