+Helm Installation
+=================
+
+Kpi Computation microservice can be deployed using helm charts in oom repository.
+
+
+Deployment Pre-requisites
+~~~~~~~~~~~~~~~~~~~~~~~~~
+- DMaaP pods should be up and running.
+
+- PM mapper service should be running.
+
+- Policy pods should be running.
+
+- Required policies should be created and pushed to the policy component. Steps for creating and pushing policy models:
+
+     1. Log in to policy-drools-pdp-0 container
+
+             .. code-block:: bash
+
+               kubectl exec -ti --namespace <namespace> policy-pdp-0 bash
+
+
+     2. Create policy type:
+
+             .. code-block:: bash
+
+              curl -k --silent --user 'healthcheck:zb!XztG34' -X POST "https://policy-api:6969/policy/api/v1/policytypes" -H "Accept: application/json" -H "Content-Type: application/json" --data '{"policy_types":{"onap.policies.monitoring.docker.kpims.app":{"derived_from":"onap.policies.Monitoring:1.0.0","description":"KPI ms policy type","properties":{"domain":{"required":true,"type":"string"},"methodForKpi":{"type":"list","required":true,"entry_schema":{"type":"policy.data.methodForKpi_properties"}}},"version":"1.0.0"}},"data_types":{"policy.data.methodForKpi_properties":{"derived_from":"tosca.nodes.Root","properties":{"eventName":{"type":"string","required":true},"controlLoopSchemaType":{"type":"string","required":true},"policyScope":{"type":"string","required":true},"policyName":{"type":"string","required":true},"policyVersion":{"type":"string","required":true},"kpis":{"type":"list","required":true,"entry_schema":{"type":"policy.data.kpis_properties"}}}},"policy.data.kpis_properties":{"derived_from":"tosca.nodes.Root","properties":{"measType":{"type":"string","required":true},"operation":{"type":"string","required":true},"operands":{"type":"string","required":true}}}},"tosca_definitions_version":"tosca_simple_yaml_1_1_0"}'
+
+     3. Create monitoring policy:
+
+             .. code-block:: bash
+
+              curl -k --user 'healthcheck:zb!XztG34' -X POST "https://policy-api:6969/policy/api/v1/policytypes/onap.policies.monitoring.docker.kpims.app/versions/1.0.0/policies" -H "Accept: application/json" -H "Content-Type: application/json" --data '{"name":"ToscaServiceTemplateSimple","topology_template":{"policies":[{"com.Config_KPIMS_CONFIG_POLICY":{"type":"onap.policies.monitoring.docker.kpims.app","type_version":"1.0.0","version":"1.0.0","metadata":{"policy-id":"com.Config_KPIMS_CONFIG_POLICY","policy-version":"1"},"name":"com.Config_KPIMS_CONFIG_POLICY","properties":{"domain":"measurementsForKpi","methodForKpi":[{"eventName":"perf3gpp_CORE-AMF_pmMeasResult","controlLoopSchemaType":"SLICE","policyScope":"resource=networkSlice;type=configuration","policyName":"configuration.dcae.microservice.kpi-computation","policyVersion":"v0.0.1","kpis":[{"measType":"AMFRegNbr","operation":"SUM","operands":"RM.RegisteredSubNbrMean"}]},{"eventName":"perf3gpp_CORE-UPF_pmMeasResult","controlLoopSchemaType":"SLICE","policyScope":"resource=networkSlice;type=configuration","policyName":"configuration.dcae.microservice.kpi-computation","policyVersion":"v0.0.1","kpis":[{"measType":"UpstreamThr","operation":"SUM","operands":"GTP.InDataOctN3UPF"},{"measType":"DownstreamThr","operation":"SUM","operands":"GTP.OutDataOctN3UPF"}]}]}}}]},"tosca_definitions_version":"tosca_simple_yaml_1_1_0","version":"1.0.0"}'
+
+
+     4. Push monitoring policy:
+
+             .. code-block:: bash
+
+               curl --silent -k --user 'healthcheck:zb!XztG34' -X POST "https://policy-pap:6969/policy/pap/v1/pdps/policies" -H "Accept: application/json" -H "Content-Type: application/json" --data '{"policies":[{"policy-id":"com.Config_KPIMS_CONFIG_POLICY","policy-version":1}]}'
+
+Deployment steps
+~~~~~~~~~~~~~~~~
+
+- Default app config values can be updated in oom/kubernetes/dcaegen2-services/components/dcae-kpi-ms/values.yaml.
+
+- Update monitoring policy ID in below configuration which is used to enable Policy-Sync Side car container to be deployed and retrieves active policy configuration.
+
+  .. code-block :: bash
+
+    dcaePolicySyncImage: onap/org.onap.dcaegen2.deployments.dcae-services-policy-sync:1.0.1
+    policies:
+    policyID:  |
+        '["com.Config_KPIMS_CONFIG_POLICY"]'
+
+- Enable KPI MS component in oom/kubernetes/dcaegen2-services/values.yaml
+
+  .. code-block:: bash
+
+    dcae-kpi-ms:
+      enabled: true
+
+- Make the chart and deploy using the following command:
+
+  .. code-block:: bash
+
+    cd oom/kubernetes/
+    make dcaegen2-services
+    helm install dev-dcaegen2-services dcaegen2-services --namespace <namespace> --set global.masterPassword=<password>
+
+- To deploy only KPI MS:
+
+  .. code-block:: bash
+
+    helm install dev-dcae-kpi-ms dcaegen2-services/components/dcae-kpi-ms --namespace <namespace> --set global.masterPassword=<password>
+
+- To Uninstall
+
+  .. code-block:: bash
+
+    helm uninstall dev-dcae-kpi-ms
+
