MUFG Network Incident Correlation Agent correlates Splunk, SolarWinds, and Nexus to cut MTTR

A vendor blog describes the MUFG Network Incident Correlation Agent, an agentic AI workflow in Network Copilot that correlates Splunk events, SolarWinds Orion metrics, and Cisco Nexus Dashboard hardware state to produce incident timelines and probable root causes in under 3 minutes.

Research Overview

The post frames multi-platform troubleshooting in enterprise datacenters as a manual process in which teams switch between log, metrics, and hardware observability systems to piece together incident context.

It then details a deployed implementation for MUFG datacenter operations that uses Network Copilot (NCP) to automate cross-platform incident correlation.

Key Findings

The blog reports a Mean Time To Resolution reduction from a 20–40 minute manual investigation window to under 3 minutes using the correlation agent.

It also states that the agent supports natural-language queries and returns a sequenced explanation intended to include a probable root cause based on correlated evidence from multiple platforms.

Technical Breakdown

The agent is positioned as an autonomous SRE-style workflow that ingests real-time signals from three sources, then correlates them by device, interface, IP addresses, and time to generate an incident narrative.

For Splunk, the post describes syslog event retrieval (including interface state changes, CRC/link errors, device reboots, port channel state changes, STP changes, and authentication events) alongside NetFlow/sFlow record retrieval covering traffic volume, packet drop counts, latency measurements, and protocol-level flow analysis.

For SolarWinds Orion, it describes SNMP-polled metrics for CPU load, memory used, interface in/out utilization, interface errors (including CRC and packet errors per hour), interface discards (including packet drops per hour), and operational interface/device status.

For Cisco Nexus Dashboard (NDFC), it describes hardware and operational visibility including switch inventory fields (hostname, model, serial, firmware, and fabric role), interface admin/operational status, fan/PSU module status, CPU and memory health, and transceiver link state (SFP optic state and physical link health).

The correlation process is described as a three-stage pipeline: query interpretation that extracts device and IP context plus a time window and query intent; data retrieval that pulls relevant data from all three platforms; and event correlation using four linking keys (device hostname/IP, interface name, timestamp, and src_ip/dst_ip flow pairs).

The post also explains an integration pattern for Splunk where the system first builds SPL search strings and then executes them through an MCP connector for results retrieval.

Operational Impact

The blog presents end-to-end examples of how the agent answers operational questions for NetOps, including investigating application slowness by correlating CPU and interface utilization with sFlow discard counters and RTT values, and identifying packet loss between two hosts by querying drop counts for an IP pair over a specified period.

In a multi-source device reachability case, it describes a workflow that checks SolarWinds health and interface metrics, queries Nexus inventory and interface states plus fan/PSU module status, and uses Splunk syslog for the last 24 hours, reporting no syslog events as consistent with the device being offline; it states the outcome as a power supply failure based on PSU fault reporting and the observed loss of reachability.

It provides an example of the before/after timing model, with manual steps including writing SPL queries, checking SolarWinds device interfaces, and inspecting Nexus hardware state followed by timestamp correlation, compared with an agent workflow where a natural-language request triggers parallel platform queries, automated correlation, an incident timeline, and a probable root cause.

Overall, the blog positions the MUFG Network Incident Correlation Agent as a Network Copilot-based workflow that automates cross-platform incident correlation across Splunk, SolarWinds Orion, and Cisco Nexus Dashboard to reduce troubleshooting time and produce structured incident explanations backed by correlated evidence.
