Abstract

An approach is described for managing error logs and corresponding error descriptors among a plurality of controller nodes of a distributed network fabric. According to such approach, an error log may include output from a runtime code trace. The runtime code trace may include storing trace statements from a currently running process in one or more of a plurality of trace buffers. The trace buffers may be memory-mapped circular buffers. Additionally, an error descriptor may be created from the error log. A globally unique identifier may be assigned to the error descriptor, and both the error descriptor and the globally unique identifier may be broadcast to each other controller node among the plurality of controller nodes.

First claim

What is claimed is:

1. A computer-implemented method of managing errors in a distributed network fabric comprised of a plurality of controller nodes, the method comprising:
receiving, at a first controller node, an error descriptor from a second controller node among the plurality of controller nodes, wherein the error descriptor is created at the second controller node based on an error log;
committing the error descriptor to a database;
assigning an identifier to the error d…
