Alarm Correlation This section describes how to configure Horizon to provide real-time feedback on alarm correlation. Situation Feedback Situation feedback lets operators provide real-time feedback on alarm correlation. Installation Enable situation feedback by installing the feature from the Karaf shell: feature:install opennms-situation-feedback To ensure that the feature continues to be installed on subsequent restarts, add opennms-situation-feedback to the featuresBoot property in the ${OPENNMS_HOME}/etc/org.apache.karaf.features.cfg. Requirements The feature requires Elasticsearch to persist the feedback records. Configure Elasticsearch Persistence From a Karaf shell on your Horizon instance, start by configuring the situation feedback persistence to use your Elasticsearch cluster: $ ssh -p 8101 admin@localhost ... admin@opennms()> config:edit org.opennms.features.situationfeedback.persistence.elastic admin@opennms()> config:property-set elasticUrl http://elastic:9200 admin@opennms()> config:update This configuration is stored in ${OPENNMS_HOME}/etc/org.opennms.features.situationfeedback.persistence.elastic.cfg. See Elasticsearch Integration for more information. Installing the feature exposes a REST endpoint that OpenNMS Helm uses to display and submit feedback. Find further information on the REST API in the Developer Guide. Shell Commands Metadata
