Re: [Dots] DOTS Telemetry: Interop Clarification #1

[[e-mail]]

Hi Jon,

It is the other way around: the server will filter out the data it will return to match the filters conveyed in GET.

So,

·         if we refer to your case (1), the PUT used for efficacy update does not interfere with the handling of GET to retrieve the server's status.

·         if we refer to your case (2), the PUT in Figure 36 sets the target (telemetry) scope. So for any telemetry-related GET, the server will only return data that is bound to the target as set in the PUT. These data is further filtered out based of any uri-query in the GET.

Cheers,
Med

Hi Med,

So for absolute clarity, the DOTS server will return the values it has internally determined (from DOTS mitigator etc.), not those provided by the DOTS client using a PUT, as modified by the GET Query filters.

Hi Jon, all,

The server will return the data that match the filters included in the GET that triggered the response.

Cheers,

Hi Med,

I think that this refers several places.


1.       Efficacy updates.  E.g.  Figure 45: An Example of Mitigation Efficacy Update with Telemetry  Attributes. Here we do an efficacy update of what the client is seeing happen to a specific resource.  If the client now does a GET against the same resource - what is returned - the last efficacy update or the current state of mitigation as seen by the DOTS server?


2.       Also, Figure 36: PUT to Send Pre-or-Ongoing-Mitigation Telemetry allows the client to update the tmid with some information.  This includes an attack-detail.  When the client wants to see what is happening with this "tmid", it does a Figure 40: GET to Subscribe to Telemetry Asynchronous Notifications for a Specific 'tmid'.  Which attack-detail is returned - the one from the PUT or the ongoing situation?

Regards

Jon

Hi Kaname,

We discussed this issue in the interim:

==
Current Uri-Path can't distinguish telemetry resources posted by the client or created by the server.
-Those are totally different resources.
For example, Uri-Query won't be applicable to the telemetry resources posted by the client.
==

Can you please identify precisely which parts of the text need to be updated?

Thank you

Cheers,
Med
