Hi,
it complains about "inst" not being declared (it is of type None). You
missed the
"inst = self"
in the __init__ method of your component. Maybe you should take a look
at the pyswitch.py from coreapps/examples.
Best regards
Bernd

Thank you for your reply. but I got same same error "
AttributeError: 'NoneType' object has no attribute 'Monitoring' "
after making the changes you told me.
inst.Monitoring =
ctxt.resolve("nox.netapps.monitoring.monitoring.Monitoring")
and run monitoring in the commandline

Hi,
the resolve() function expects a string. You don't even need to
import the monitoring stuff.
inst.Monitoring =
ctxt.resolve("nox.netapps.monitoring.monitoring.Monitoring")
Of course you should ensure that the Monitoring module is
resolvable, that means, it must be loaded by NOX either by
issueing it on the commandline or (which is the cleaner way) it
must be declared in the meta.json file of your component as a
dependency.
Hope that helps.
Best regards,
Bernd

Hello everyone,
I want use the methods in the Monitoring component to send flow
stats request from my own component.
I did the following two variations to user the monitoring component
1. include monitoring component in the dependency list of
my components meta.json file
import the monitoring component as: from
nox.netapps.monitoring.monitoring import Monitoring
then inside my component :
def __init_(self, ctxt):
global inst
Component.__init__(self,ctxt)
inst.Monitoring = ctxt.resolve(Monitoring)
and then use it like, inst.Monitoring.send_flow_
stats_request(....)
this gives me Monitoring description not found error.
2. when I tried to use the monitoring component in the command
line after the proper import as follows
> ./nox_core -i ptcp:6633 monitoring mycomponent
it gives me again the following error.
inst.Monitoring = ctxt.resolve(Monitoring)
AttributeError: 'NoneType' object has not attribute
'Monitoring'
please tell me where my mistake is.
thanks
