Hello there,

I’m trying to read all data from my CPE’s when they comunicate with the cwmp.  
To do this I’m trying this provision:  
declare(“InternetGatewayDevice.\*”, {value: Date.now()});

But it’s not working.  
Any ideas?  
Thanks

Do you see any error and other information in the log file ?

I see some invalid sessions there, but when I try the same provision to one specific device it works fine…

This will only read the immediate parameters under ‘InternetGatewayDevice’. You need:

```
declare(“InternetGatewayDevice.*”, {path: Date.now(), value: Date.now()});
declare(“InternetGatewayDevice.*.*”, {path: Date.now(), value: Date.now()});
declare(“InternetGatewayDevice.*.*.*”, {path: Date.now(), value: Date.now()});
...

```

But you probably shouldn’t do that. Fetch only what you need.

Going along with what @zaidka said. The only reason I refresh the top level node is in development when I’m trying to see everything the CPE supports. And in that case I refresh the top level node from within the GUI and wait for it to grind away.

In production, I never refresh the entire device parameter model. 95% of the data I won’t ever care about, so why put the extra load on the CPE to respond to the GPN/GPV requests, on Mongo to store all that data, and Redis to cache it?
