Hi all, Let me start by saying I am quite a novice with Apache Ignite.
Here is my question : I want to be able to monitor and cancel tasks running or that are going to run on worker nodes of an Ignite Cluster (say for example if one task takes too long to complete), and without using Visor. I tried to query all EVTS_TASK_EXECUTION events (from EventType) on all nodes as follows: Ignite grid = Ignition.ignite("GRID_NAME"); Collection<Event> allEvents = grid.events().remoteQuery(event -> true,0, EventType.EVTS_TASK_EXECUTION) for (Event evt : allEvents){ TaskEvent taskEvent = (TaskEvent) evt; System.out.println(taskEvent); } Each TaskEvent, has a taskSessionId() method, and a .node() method. It seems that the .node() method returns the client node that originated the task with the corresponding IgniteUuid returned by taskSessionId(). On the other hand, when looking at ClusterMetrics for worker nodes I can retrieve the number of Jobs currently running on Worker Nodes, current CPU load etc : ClusterGroup workerNodes = grid.cluster().forAttribute("ROLE","WORKER"); for(ClusterNode node : workerNodes.nodes()){ System.out.println(node.metrics().getCurrentActiveJobs()); } How could I 1) Cancel tasks currently being run on worker nodes (whose number are displayed in the result of getCurrentActiveJobs()) or 2) Cancel tasks dispatched by the clients nodes, for which I have an IgniteUuid , possibly without using grid.close() or such hard methods.
