The node red docs describing how to handle messages will show you how to get the path to that item from the payload.

Thanks for express answer Colin. Now the problem is almost solved.

I use change node .

Set msg.payload.value  
to msg.payload

Value came instead **"[Circular ~]"**

```auto
[{"id":"d4170f7d.697fd","type":"tab","label":"Flow 1","disabled":false,"info":""},{"id":"6791bfb0.f0061","type":"snmp walker","z":"d4170f7d.697fd","host":"10.67.20.28","community":"public","version":"1","oids":"1.3.6.1.4.1.534.1.4.4.1.3","timeout":5,"name":"CMUPS CUR.
