Christian Kreibich	7edd1a2651	Management framework: allow selecting cluster nodes in get_id_value ... This adds an optional set of cluster node names to narrow the querying to. It similarly expands the dispatch mechanism, since it likely most sense for any such request to apply only to a subset of nodes. Requests for invalid nodes trigger Response records in error state.	2022-04-18 12:38:54 -07:00
Christian Kreibich	788348f9d6	Management framework: allow dispatching "actions" on cluster nodes. ... This adds request/response event pairs to enable the controller to dispatch "actions" (pre-implemented Zeek script actions) on subsets of Zeek cluster nodes and collect the results. Using generic events to carry multiple such "run X on the nodes" scenarios simplifies adding these in the future.	2022-04-15 18:51:56 -07:00
Christian Kreibich	337c7267e0	Management framework: allow agents to communicate with cluster nodes ... This provides Broker-level plumbing that allows agents to reach out to their managed Zeek nodes and collect responses. As a first event, it establishes Management::Node::API::notify_agent_hello, to notify the agent when the cluster node is ready to communicate. Also a bit of comment rewording to replace use of "data cluster" with simply "cluster", to avoid ambiguity with data nodes in SumStats, and expansion of test-all-policy.zeek and related/dependent tests, since we're introducing new scripts.	2022-04-15 18:51:54 -07:00
