Overview

Missing Heartbeat MS is one among the higher-level DCAE services responsible for tracking VES heartbeat events generated by the VNF's posted into DMAAP by VESCollector. Each VNF when configured to be monitored will be checked periodically by service if Heartbeat event was received. If the Heartbeat events from specific VNF is missed 'x' times (configured through policy), then Heartbeat Service will generate a control-loop event output. Once the VNF starts sending Heartbeat events, the service will automatically clear the original Onset created.

Following diagram explains the event flow involved.

Blueprint/image

Βlueprint (deployment artifact) : https://git.onap.org/dcaegen2/services/heartbeat/tree/dpo/k8s-heartbeat.yaml

Input file (deployment input) : https://git.onap.org/dcaegen2/services/heartbeat/tree/dpo/k8s-heartbeat.yaml

Docker image : nexus3.onap.org:10001/onap/org.onap.dcaegen2.services.heartbeat:2.1.0

Deployment Prerequisite/dependencies

Heartbeat service has following dependencies

Dmaap : Usedfor sub/pub for VES heartbeat events; this should be deployed using OOM helm chart

ConfigBindingService : Used for fetching the latest configuration from Consul; this should be deployed using DCAE OOM charts.

Postgres : Used for Event data store, leader management (scale), heartbeat computation. Blueprint includes postgres plugin and postgres node, which will be used for setting up the PG pod.

Deployment Steps

Deployment of Heartbeat Service can be done using Dashboard UI or CloudifyUI or via CLI. Below steps are based on CLI.

Transfer blueprint component file in DCAE bootstrap POD under /blueprints directory
Transfer blueprint component inputs file in DCAE bootstrap POD under / directory
Log-in to the DCAE bootstrap POD's main container
Validate blueprint
Code Block
language bash
theme Midnight
title Validate Blueprint
linenumbers true
cfy blueprints validate /blueprints/k8s-heartbeat.yaml
Verify Plugin versions in target Cloudify instance match to blueprint imports
Code Block
language bash
theme Midnight
title Verify Plugin version
linenumbers true
cfy plugins list
If the version of plugin used are different, update the blueprint import to match.

Deploy Service

Code Block

language	bash
theme	Midnight
title	Upload and deploy blueprint
linenumbers	true

cfy install -b heartbeat -d heartbeat -i /k8s-heartbeat-inputs.yaml /blueprints/k8s-heartbeat.yaml

To un-deploy

Uninstall running component and delete deployment
Code Block
language bash
theme Midnight
title Uninstall component
linenumbers true
cfy uninstall heartbeat
Delete blueprint
Code Block
language bash
theme Midnight
title Delete blueprint
linenumbers true
cfy blueprints delete heartbeat

Initial Validation

After deployment, verify if Heartbeat POD and PG pod are running correctly

Code Block

language	bash
theme	Midnight
title	Verify Heartbeat is running
linenumbers	true

root@k8s-rancher:~# kubectl get pods -n onap | egrep "heartbeat|postgres"

And then check the logs to see if it can connect to DMaaP, polling for events.

To simulate the event flow and trigger missing heartbeat event, we can simulate a VES event into Heartbeat subscription topic (using curl).

Generate Heartbeat CL Onset

Send a triggering event to DMaaP topic unauthenticated.SEC_HEARTBEAT_OUTPUT

Before sending, validate following

Correct DMaaP address
"eventName" field in VES input matches eventName configuration set in Heartbeat Service
"lastEpochMicrosec" in reflecting current time stamp approximately

Dynamic Configuration Update

As the Heartbeat service periodically polls Consul KV using configbindingService api's - the run time configuration of Heartbeat service can be updated dynamically without having to redeploy/restart the service. The updates to configuration can be triggered either from Policy (or CLAMP) or made directly in Consul.

Locate the servicename by executing into Heartbeat Service pod and getting env HOSTNAME value

Code Block

theme	Midnight
title	ServiceName of Heartbeat Service

root@k8s-rancher:~# kubectl exec -it -n onap dep-s78f36f2daf0843518f2e25184769eb8b-dcae-heartbeat-servithzx2 /bin/bash
Defaulting container name to s78f36f2daf0843518f2e25184769eb8b-dcae-heartbeat-service.
Use 'kubectl describe pod/dep-s78f36f2daf0843518f2e25184769eb8b-dcae-heartbeat-servithzx2 -n onap' to see all of the containers in this pod.

misshtbt@s78f36f2daf0843518f2e25184769eb8b-dcae-heartbeat-service:~/bin$ env | grep HOSTNAME
