Overview

The PM Subscription Handler (PMSH) is a micro service written in Python, which allows for the definition and unlocking creation of PM subscriptions on one or more network function (NF) instances.

Deployment Prerequisite/dependencies

The following components must be up and running to successfully deploy PMSH
1. DCAE Platform
2. SDC
3. CLAMP
4. POLICY
5. A&AI (Should have at least 1 PNF registered)

Deployment Steps

Due to a bug (DCAEGEN2-2136). In the Frankfurt release, there is a workaround required in order to deploy the PM Subscription Handler. The monitoring policy for the microservice needs to be manually inserted into CONSUL. This requires two steps:

...

Code Block

language	bash
theme	Midnight
title	Expose CONSUL service

kubectl expose svc -n onap consul-server-ui --name=x-consul-server-ui --type=NodePort

2. Insert the monitoring policy into CONSUL

Code Block

language	bash
theme	Midnight
title	PUT policy into CONSUL

curl -X PUT \
  http://<k8s-node-ip>:<consul-port>/v1/kv/dcae-pmsh:policy \
  -H 'Content-Type: application/json' \
  -d '{

                }

        ]
    }
}'

Starting in Frankfurt, all DCAE service blueprints are bootstrapped, meaning they are all available in the inventory by default and do not need to be onboarded manually. Deployment of PMSH can then be done using Dashboard UI/Cloudify UI or via CLI. Below steps are based on CLI .

...

Validate blueprint

...

using the deployment handler.

1. Get the typeId of PMSH using the inventory API

Code Block

title
language	bash
theme	Midnight

...

cfy blueprints validate /blueprints/k8s-pmsh.yaml

...

Get serviceTypeId from DCAE inventory

curl https://<k8s-node-ip>:<inventory-port>/dcae-service-types

The PMSH typeID can then be taken from the response

Code Block

language

...

...

cfy plugins list

If the version of plugin used are different, update the blueprint import to match.
