Re: Connecting to OPCUA

2017-04-21 Thread Raveendran, Varsha 
Thank you for pointing this out, wade and Aldrin. i will set it up correctly.

I have a follow up question to this. Currently the plan is to use the GetValue 
processor to continuously receive values in a raspberry pi that will in turn 
push the values to a NiFi server installed in cloud.

We want to first understand the rate at which the Pi can receive the values 
using the opc ua processors. That means  GetValue must continuously hit the 
endpoint and get the values. I imagine this like a "while(true)" loop coming 
from a software background!
Currently I see that the tasks/time is only about 10/seconds and that the queue 
before GetValue is filling up very soon. I tried a couple of optimizations - 
Increased concurrent threads, Decreased scheduled time so that it can get the 
values from OPC server at a faster rate and also the yield time.
However, none of these seem to increase the rate. We are hoping for atleast a 
1000 tag values/second to be sent from the pi into the cloud.

Any suggestions?
I'm new to NiFi and still learning.

Thanks & Regards,
Varsha

Hi Varsha,

Went through the build process quickly on my side building the dependent UA 
Java and then referencing that version in the listed project with some cleanup 
and had the GetNodeIds processor available in NiFi after copying the resulting 
NARs into my lib directory.

Doing some looking through other repositories of that user, it appears you were 
actually using this one https://github.com/wadesalazar/Nifi-OPCUA-Processors 
which has the processor your listed above, GetExpandedNodeIds.

I built https://github.com/wadesalazar/NIFI-OPCUA from source code using Maven. 
However, after adding the nar file to lib folder I am unable to view GetNodeIds 
on NiFi canvas.
Instead I see GetExpandedNodeIds.  Are these processors performing the same 
functionality?

I’m able to connect to the specified OPC endpoint using GetExpandedNodeIds  
though without the Controller Service created. Just wanted to confirm that I’m 
on the right track and did not make a mistake while  building the nar file.

Connecting to OPCUA

Looking at the email below

"
I am following the steps described in 
https://community.hortonworks.com/articles/90355/collect-data-from-opc-ua-protocol.html
 to connect to an OPC UA server from MiNiFi.

"

It appears that both
https://github.com/wadesalazar/Nifi-OPCUA-Processors
and
https://github.com/wadesalazar/NIFI-OPCUA
have been built and installed

I understand the titles are too close but the former repo is the only one that 
has the GetExpandedNodeIds processor and is, in fact, intended to be stand 
alone as you describe.  This is intended for basic troubleshooting.

Can you please remove all OPC-UA .nar packages from your lib folder and remove 
all of the associated processors and services then restart.  Then install only 
the .nar from the build of https://github.com/wadesalazar/Nifi-OPCUA-Processors
