A system for constructing and storing procedures for troubleshooting computer networks. A user can design and add troubleshooting steps, via a GUI, to define the procedure including annotations. Each step is configured to take an action on the network. The order of the steps can be re-arranged via the GUI. The procedure can be stored and re-executed by another user.

A network 50 is hierarchically divided into network devices 501 to 506, areas, and the like to be monitoring targets, and a monitoring device 100 monitors a divided monitoring target. A monitoring device of an N-th layer (here, N≥2) that is an upper layer with respect to a first layer monitors information of reachability between user connection points received from a monitoring device of an (N−1)-th layer that is a lower layer and network devices connecting monitoring targets of the (N−1)-th layer making up monitoring targets of the N-th layer and connection statuses between the network devices and areas that are monitoring targets. The monitoring device determines the presence/absence of reachability between user connection points belonging to different monitoring targets of the (N−1)-th layer on the basis of this reachability and the connection statuses.

Systems and methods for displaying onboard service information for vessels are described. In some embodiments, a method comprises obtaining time range data indicating a time range; obtaining corresponding trips within the time range for each of a plurality of vessels; and obtaining status of an onboard service provided during each trip of the corresponding trips for each of the plurality of vessels. In response to receiving a request for displaying service performance information for the plurality of vessels, first graphical interface data is generated. The data represents a plurality of vessel identifiers that corresponds to the plurality of vessels; a plurality of trip icons for the corresponding trips for each of the plurality of vessels, and a timeline that represents the time range. The data is transmitted to a display device to cause the display device to generate and to display a trip-schedule viewer representation.

In some aspects, the disclosure is directed to methods and systems for monitoring and isolating issues over physical layer (layer 1) paths using Flexible Ethernet (FlexE) protocols via client-based operations, administration, and maintenance (OAM) management. Each node within a FlexE communications path may dynamically insert, extract, and/or replace OAM messages from FlexE data streams as needed to ensure that the OAM messages may be provided unimpeded to a destination (e.g. monitoring server or other device), as well as inserting additional monitoring data (e.g. bit error rates, delay measurements, loss measurements, threshold crossing alerts, or other such monitoring notifications or data) for intermediary nodes.
