Automatically detecting an error in a communication and automatically determining a source of the error

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors, cause the one or more processors to:
• monitor a communication between multiple devices for an error associated with at least one of:
• one or more network interface controllers (NICs) of the multiple devices,
• one or more transceiver components of the multiple devices, or
• one or more transmission lines between the multiple devices;
• detect the error associated with the communication between the multiple devices;
• determine whether an error metric satisfies a threshold error metric;
• identify a source of the error using a loopback test based on determining whether the error metric satisfies the threshold error metric,
• the loopback test being applied to the one or more NICs or the one or more transceiver components;
• and
• provide error source information based on identifying the source of the error.

A method, comprising:

• monitoring, by a first device, a communication between the first device and a second device;
• detecting, by the first device, an error associated with the communication between the first device and the second device,
• the error being caused by the first device, the second device, or a transmission line used by the first device and the second device to communicate;
• performing, by the first device, a comparison of an error metric and a threshold error metric,
• the error metric being determined from the error;
• determining, by the first device, that a result of the comparison indicates that the error metric satisfies the threshold error metric;
• identifying, by the first device, a source of the error using a loopback test based on determining that the error metric satisfies the threshold error metric;
• and
• performing, by the first device, an action based on identifying the source of the error,
• the action being associated with the source of the error.
