Example 1 with NodeEvent

use of org.apache.nifi.cluster.event.NodeEvent in project nifi by apache.

the class StandardNiFiServiceFacade method getNode.

private NodeDTO getNode(final NodeIdentifier nodeId) {
    final NodeConnectionStatus nodeStatus = clusterCoordinator.getConnectionStatus(nodeId);
    final List<NodeEvent> events = clusterCoordinator.getNodeEvents(nodeId);

}

Example 2 with NodeEvent

use of org.apache.nifi.cluster.event.NodeEvent in project nifi by apache.

the class NodeClusterCoordinator method addNodeEvent.

private void addNodeEvent(final NodeIdentifier nodeId, final Severity severity, final String message) {
    final NodeEvent event = new Event(nodeId.toString(), message, severity);
    final CircularFifoQueue<NodeEvent> eventQueue = nodeEvents.computeIfAbsent(nodeId, id -> new CircularFifoQueue<>());
