Hello Oliver, and thank you for the reply.
I am trying to find the best way to get up-to-date (near real-time if
possible) stats from a CPE. What I'm currently doing is performing a
getParameterValues API call, but the response is always 202 (queued),
so
of course the parameters are not updated until the device polls. I've
tried increasing the timeout to 10000 (10 seconds), but the request
never takes 10 seconds to get a the 202 response, so I don't know that
increasing the timeout is even working.
What do you mean with "stats"? Have up-to-date values of all parameters
of that device in your ACS?
I mean whatever parameters I specify. In my case it would be
Signal-to-Noise Ratio and Attenuation, but the specifics don't really
matter.
My API URL looks like this: http://{my server ip}:7557/devices/{device
id}/tasks?timeout=10000&connection_request
Can anyone offer any advice on getting a real-time response from a
CPE?
I think you should use notifications.
Can you please point me to the documentation for notifications? I am
unable to find any.
Or is there another way to get up-to-date stats? Perhaps there is a
way
to have each CPE update certain parameters each time they poll? Does
anyone know what parameters are updated when a device polls? Maybe I
can add a few to that list?
With the periodic inform, only ~ 10 parameters are sent to the ACS. I
don't know if you can append to that list.
Perhaps someone else can speak to this?
Or maybe by using a preset? I don't know anything about presets, but
there is an existing one called "tracking" that seems to be updating a
few specific parameters every 30 minutes.
With presets, you can refresh the whole tree (InternetGatewayDevice.)
periodically.
Would it be bad to lower the refresh time significantly? Say to 300
seconds? At least that way I'd know that these parameters will be no
more than 5 minutes old at any given time.
What do you mean with "refresh time"? The inform interval?
I don't know how to get a screenshot to you, but the Configurations for
the Preset named "tracking"
says, "Refresh {parameter name} every {xxxx} seconds" I didn't set this
up; I assumed it was a
default preset setup when the server was installed.
What I want to know is: if lower the Refresh Time from 1800 to
something much lower, like 300, will cause the server to bog down in
some way?
At the end of the day, what I really need to know is simply the BEST way
to get specific parameters to stay up-to-date, or to only be a few
minutes old at worst.
Thanks,
Mark
