  • Significant portion of providers show extreme deviations
  • Cross-validation with standard deviation alerts

• Required Actions:

  • Cross-reference with P5 alerts

2. Timestamp Alerts (P5)

• Trigger Conditions:
  • Data age exceeds 2 minutes
  • Based on INTERVAL_SYNC_SIGNED_DATA * intervalsToCheck
  • Configurable through alerts-common settings

Alert Handling Requirements

Standard Deviation (P5)

1. Initial Assessment:

   • Monitor deviation percentages
   • Track duration of deviations
   • Check provider count ratios

2. Escalation Criteria:

   • After 1 hour of persistent deviation
   • When 30% of providers are affected
   • Multiple feeds showing patterns

Critical Deviation (P2)

1. Immediate Actions:

   • Begin 15-minute observation
   • Record deviation magnitudes
   • Check historical patterns

2. Escalation Criteria:

   • After 15 minutes of persistent deviation
