Overview

Deployment Prerequisite/dependencies

1. DCAE and DMaaP pods should be up and running. 

2. DMaaP Bus Controller PostInstalls job should have completed successfully (executed as part of an OOM install).
3. Make sure that cfy is installed and configured to work with the Cloudify deployment.

Deployment Steps

Execute bash on the bootstrap Kubernetes pod. 

kubectl -n onap exec -it <dcaegen2-dcae-bootstrap> bash

...

Go to the /blueprints directory.

...

Run the Cloudify install command to install the pm-mapper with the recently downloaded blueprints, and the newly created inputs file k8s-slice-input.yaml.

$ cfy install k8s-slice-analysis-ms.yaml -i  k8s-slice-input.yaml --blueprint-id sliceanalysisms

...

$ cfy install k8s-slice-analysis-ms.yaml -i k8s-slice-input.yaml --blueprint-id sliceanalysisms

...

Slice analysis MS consumes PM message from PM-Mapper and analyze the slice PM data and triggers the closed-loop if needed. For analyzing the PM data, it consumes data from Config DB.

The PM data which the slice analysis MS consumes currently are:

SM.PrbUsedDl.snssai

SM.PrbUsedUl.snssai

Bulk PM Flow:

1. NF notifies VES Collector that a PM file is available for upload.
2. Data File Collector downloads PM Files from the NF and publishes them to Data Router.
3. PM-Mapper creates custom Performance events (VES) from the PM File data according to PM Mapping File.
4. Analytics Applications (Slice Analysis MS) use these performance events for targeted analysis of network operations.

Slice Analysis MS Flow:

1. Slice analysis ms consumes PM messages from PERFORMANCE_MEASUREMENTS topic
2. For analysis Slice analysis MS consumes various data from Config DB
   1. List of Network Functions which serves the snssai
   2. List of RICs and its corresponding cell mappings of the snssai
   3. Current Configuration of the RICs
   4. Slice Profile of the snssai
   5. Subscriber details of the snssai (for sending the onset message to policy)
3. With the help of pm data, Slice analysis MS computes the DLThptPerSlice and ULThptPerSlice for the RICs of the snssai, and the computed value is compared with the current configuration of the RICs.
4. If the change in configuration exceeds the minimum percentage value which is kept as a configuration parameter, then the closed-loop will be triggered by posting the onset message to DMAAP

Architecture

 Image Added

DMAAP Client - creates a thread pool for every DMAAP topic consumer. The thread polls the DMAAP topic for every configured time interval and whenever a message is received it stores that message in the Postgres DB.

PM Thread - reads the PM event from the database and puts the PM sample in the internal queue in the format which is needed for further processing.

Consumer Thread - Consumes pm samples from the internal queue and make all the required Config DB calls, perform the analysis, and puts the onset message to the DMAAP topic

Deployment Prerequisite/dependencies

1. DCAE and DMaaP pods should be up and running. 

2. DMaaP Bus Controller PostInstalls job should have completed successfully (executed as part of an OOM install).
3. PM mapper service should be running.
4. Config DB service should be running.
5. Make sure that cfy is installed and configured to work with the Cloudify deployment.

Deployment Steps

1. Execute bash on the bootstrap Kubernetes pod. 

   Code Block
   language bash theme Emacs
   kubectl -n onap exec -it <dcaegen2-dcae-bootstrap> bash

   
   

2. Go to the /blueprints directory.

3. Check that the tag_version in the slice-analysis-ms blueprint is correct for the release of ONAP that it is being installed on see Nexus link for slice-analysis-ms for tag_versions
4. Refer blueprints for sliceanalysis ms: https://gerrit.onap.org/r/gitweb?p=dcaegen2%2Fplatform%2Fblueprints.git;hb=refs%2Fchanges%2F20%2F114120%2F3;f=blueprints%2Fk8s-slice-analysis-ms.yaml

5. Create an input file.        

   Expand
   title Sample k8s-slice-input.yaml
   tag_version: nexus3.onap.org:10001/onap/org.onap.dcaegen2.services.components.slice-analysis-ms:1.0.1 config_db: http://<ip>:<port> initialDelaySeconds: 50000

   6. Run the Cloudify install command to install the slice-analysis-ms with the blueprint and the newly created input file k8s-slice-input.yaml.

   Code Block
   language bash theme Emacs
   $ cfy install k8s-slice-analysis-ms.yaml -i k8s-slice-input.yaml --blueprint-id sliceanalysisms

   7. To un-deploy

   Code Block
   language bash theme Emacs
   $ cfy uninstall sliceanalysisms

   
   

Logging

 Since, the MS is deployed as a pod in the kubernetes, we can check the logs by using the command

$ kubectl logs <pod-name> –namespace onap

Functional Tests

1. Before performing the functional tests, test data has to be populated in Config DB service. For populating the test data run the config_requests_script.sh passing the IP of the Config DB service as an argument.

Example

$ ./config_requests_script.sh 192.168.200.9

2. The zip file contains six PM files (3 sample files for one network function and the other 3 sample files for another network function of an S-NSSAI) and a script. Once the Slice analysis MS is up and running, run the script which will trigger PM mapper with these files and PM mapper outputs the corresponding PM messages in the PERFORMANCE_MEASUREMENTS topic which the slice analysis MS will consume and process further.

3. The slice analysis MS after analyzing the PM messages, outputs the policy onset message to unauthenticated.DCAE_CL_OUTPUT topic. For the above given input, the output would be
