Introduce Conditional and Adjacency-Aware Correlation with Path-Based Grouping Feature in AIOps Topology Correlation

The current correlation model in IBM Cloud Pak for AIOps can sometimes over-group alerts by combining all downstream nodes connected to a common parent, even when the parent (anchor) node itself has no alert. This behavior can result in large, noisy alert groups that do not accurately reflect the true fault domain, making root cause analysis more difficult.

Dynamic templates currently treat the parent as “context,” resulting in unioned groups for all connected downstream nodes. Multi-hop and transitive connections further exacerbate over-grouping.

As a Telecomm customer, it is very important to have a grouping with proper identification of Root Cause and ensure no localized faults are missed due to transitive groupings.

Example Scenario:

  • Topology: A → B → C → D

  • Alerts: B, C, and D generate critical alerts, but A (the upstream anchor) has no alert.

  • Current Behavior: The correlation engine groups B, C, and D together in a single group, even though A is healthy.

Impact:

  • Operators see a large, misleading alert group.

  • Overly large groups (100+ alerts) due to union of transitive connections.

  • True root cause (e.g., Node C failure) is obscured.

  • Localized issues related to C; example Node Failure will be unnoticed when the event gets correlated with alerts in B and D.

Proposed Solution:

Introduce Conditional and Adjacency-Aware Correlation with Path-Based Grouping, with the following capabilities:

A. Conditional (Anchor-Based) Correlation

  • Provide option to group downstream alerts only if the anchor (parent) alert is present.

B. Adjacency / Path-Aware Correlation

  • Provide option to correlate only nodes/entities connected through active alert paths.

  • Support multiple alternative paths; any valid path of active alerts is sufficient for correlation.

Example Scenario

Connectivity path is as follows :-

NodeA-->NodeB,NodeC,NodeD,NodeG

NodeB-->NodeE-->NodeF

NodeC-->NodeF

Note :- All grouping should be adhered to existing correlation window logic and should be based on the first occurrence of anchor node alert.

AlarmRaised

ExpectedGroup(Within Defined Correlation Window)

A,B,F

{A,B} SHOULD BE GROUPED AND ALERTS FROM NODEF SHOULD NOT FALL UNDER THE SAME GROUP AS THERE IS NO ACTIVE ALERT IN DIRECT PATH CONNECTING NODEF (WHICH IS ALERT FROM NODEE)

B,C,D

DONOT GROUP, AS TEHRE IS NO DIRECT CONNECTIVITY BETWEEN THEM AND ANCHOR NODE(NODEA) ALERT IS NOT ACTIVE

B,E,F

GROUP THEM TOGETHER AS THERE ARE DIRECT CONNECTIVITY AND ACTIVE ALERT IN PATH

A,C,F

GROUP THEM TOGETHER AS THERE ARE DIRECT CONNECTIVITY AND ACTIVE ALERT IN PATH

A,B,C,D

GROUP THEM TOGETHER AS THERE ARE DIRECT CONNECTIVITY AND ACTIVE ALERT IN PATH

A,E,F

GROUP ALERTS FROM E AND F BUT NOT FROM NODEA AS THERE IS NOT ACTIVE ALERT IN PATH LEADING TO NODEE ( NO ACTIVE ALERT FOR NODEB LEADING THE PATH FROM A-->B-->E-->F)

G,D,A

GROUP THEM TOGETHER AS THERE ARE DIRECT CONNECTIVITY AND ACTIVE ALERT IN PATH

G,D

DONOT GROUP, AS TEHRE IS NO DIRECT CONNECTIVITY BETWEEN THEM AND ANCHOR NODE(NODEA) ALERT IS NOT ACTIVE
