Hi
I would like to start a discussion on the need to clarify some of the
requirements for Monitoring and Management Requirements
This area is covered in chapter 7.4.5 in the VNF Provider part of the ONAP
Documentation
(http://onap.readthedocs.io/en/latest/submodules/vnfrqts/requirements.git/docs/Chapter7.html)
There are a few issues to be dealt with here.
Initially the whole chapter was one requirement
"R-51910 The xNF MUST provide all telemetry (e.g., fault event records, syslog
records, performance records etc.) to ONAP using the model, format and
mechanisms described in this section." This is not a standalone requirement as
it requires the whole chapter to provide context. What has happened in this is
that almost all statements within the chapter that can be read as a requirement
have been given a requirement tag themselves.
Also this requirement is not testable as "all telemetry" is not defined, and
the chapter doesn't cover needs of some types of telemetry. So this requirement
needs to be re-worded or removed, and the remaining "sub-requirements" in the
chapter need to be given Requirement Tags.
Also the context of the chapter context is written on the assumption JSON
(with/without AVRO) would be used for telemetry delivery. But at some stage a
GPB was added as another telemetry delivery mechanism. It is now not clear
whether VNF providers are required to provide JSON and GPB, or JSON or GPB. The
scenarios for use of JSON and/or GPB need to be clarified.
The chapter is written from the perspective of Event handling, as mentioned
above it doesn't cover all telemetry types contrary to R-51910. For example the
mechanism for the collection of information such as large counter files is not
covered properly here.
Section 7.4.5.6. Addressing and Delivery Protocol also contains CM related
requirements that belong to Chapter 7.3
Section 7.4.5.8. Security contains security requirements common to CM and
Monitoring so probably should be in a new Chapter 7.5
Regards
John
