COB diagnostic tool
T24 COB Failure Diagnostic Wizard
Turn a vague report such as “COB is stuck” into prioritised safe checks, evidence to capture, and an escalation summary without sending incident data anywhere.
Start the diagnostic
This browser-only tool structures first checks. It does not connect to T24, transmit answers, store incident data, or replace an approved operational runbook.
What the wizard covers
- COB not started and missing trigger paths
- Stopped services and unexplained service-state mismatches
- Long-running or potentially stalled jobs
- Explicit failures and first-error analysis
- State alignment after a database or application restore
- Green status with missing outputs or failed reconciliation
For deeper background, read what COB is in T24, why a green batch status can be misleading, and the incident escalation checklist.
Privacy and operational safety
Answers remain in the current browser tab. The copied summary is deliberately generic, but remove customer data, credentials, account numbers, message payloads, internal hostnames, and environment-specific secrets before sharing it.
This is a diagnostic aid, not an automated recovery system. Any action that changes processing state must follow local approval and runbook controls.
