Christian Kreibich 24a495da42 Management framework: Supervisor extensions for stdout/stderr handling ... This improves the framework's handling of Zeek node stdout and stderr by extending the (script-layer) Supervisor functionality. - The Supervisor _either_ directs Zeek nodes' stdout/stderr to files _or_ lets you hook into it at the script level. We'd like both: files make sense to allow inspection outside of the framework, and the framework would benefit from tapping into the streams e.g. for error context. We now provide the file redirection functionality in the Supervisor, in addition to the hook mechanism. The hook mechanism also builds up rolling windows of up to 100 lines (configurable) into stdout/stderr. - The new Mangement::Supervisor::API::notify_node_exit event notifies subscribers (agents, really) that a particular node has exited (and is possibly being restarted by the Supervisor). The event includes the name of the node, plus its recent stdout/stderr context.		2022-05-31 12:55:21 -07:00
