Re: [Dots] multiple values in the filter RE: DOTS telemetry Issues picked up in Interop Testing

[Jon Shallow <[e-mail]>]

For me, - (minus) is for a range and , (comma) for distinct elements.
Spaces not allowed.

Re-, 

 

If we want to allow for multiple values to be included, all what we need is
to agree on the separator to be used for ranges and for distinct elements.
We can get rid of [].

 

Cheers,

Hi all,

 

A further thought on the use of Uri-Queries to clarify the AND/OR usage.

 

If you only allow one query per query type and put the match list in an
array, then this will be an OR of the array list (the same as we do for the
target* definitions right now.  E.G. :-

 

Uri-Query: target_prefix=[1.2.3.4/32,4.3.2.1/32]

Gives either 1.2.3.4 or 4.3.2.1 as a valid match.

 

And 

Uri-Query: target-prefix=[1.2.3.4/32,4.3.2.1/32]

Uri-Query: lower-port=[80,443]

Gives (either 1.2.3.4 or 4.3.2.1) and (either port 80 or 443)

 

[] should not include spaces and comma used as a separator.

 

[Med] The issue I have with this is that we will need to handle cases where
both lower-port and upper-port are present. Not sure what would be the
benefit of allowing multiple key values, compact uris? If that’s a concern,
we may consider shortened names in the query (e.g., s/target-prefix/tp,
s/lower-port/lp, ..).

 

Jon> fair point about lower and upper ports.  Uri-Query:
target-port[80-85,443] works for me and covers both ranges and individual
ports.

 

Jon> As this would be options on a GET request that has no body data, I
don’t think that I am too worried about using shortened names at this point.
