Description
SUMMARY
when the sensor tries to read from the datastore (st2KV) with self.sensor_service.list_values(prefix'something'), it raises this Error:
ERROR [-] Sensor "MySensor" run method raised an exception: no such option in group api: max_page_size.
WARNING [-] Sensor "MySensor" run method raised an exception: no such option in group api: max_page_size.
KeyError: ('api', 'max_page_size')
limit = limit or cfg.CONF.api.max_page_size
oslo_config.cfg.NoSuchOptError: no such option in group api: max_page_size
ERROR [-] ('api', 'max_page_size')
ERROR [-] limit = limit or cfg.CONF.api.max_page_size
ERROR [-] no such option in group api: max_page_size
STACKSTORM VERSION
v3.5.0
OS, environment, install method
using docker version
Steps to reproduce the problem
- create a new pack with sensor class :
from st2reactor.sensor.base import PollingSensor
class MySensor(PollingSensor):
def __init__(self, sensor_service, config=None):
super(SyslogAlertsSenderSensor, self).__init__(
sensor_service=sensor_service,
config=config,
poll_interval=60
)
...
def poll(self):
payloads = self.sensor_service.list_values(local=False, prefix='something')
...
- install the pack
- enable the sensor and look at the logs of st2sencorcontainer.
Expected Results
DEBUG [-] Sensor my_pack.MySensor started.
Actual Results
ERROR [-] Sensor "MySensor" run method raised an exception: no such option in group api: max_page_size.
Workaround
add this code to sensor file:
from oslo_config import cfg
try:
api_group = cfg.OptGroup('api')
cfg.CONF.register_group(api_group)
cfg.CONF.register_opts([cfg.IntOpt('max_page_size', default=50)], group=api_group)
except cfg.DuplicateOptError:
pass
