Enhance Database Out-of-Sync Alerting to Include Lag Metrics

 Enhance Database Out-of-Sync Alerting to Include Lag Metrics

Description:

Current Situation: The existing alerting mechanism is designed to notify the team when the PostgreSQL database goes out of sync. However, the current alerts do not provide details on the extent of the lag, which limits our ability to assess the severity of the issue and respond accordingly.

Proposal: I propose enhancing the existing alerting system to include the specific lag value/metric when an out-of-sync event occurs. This enhancement will provide more actionable insights by indicating how far behind the database has fallen, allowing for better prioritization and more informed decision-making.

Implementation Details:

• Script Modification: There is already an existing script responsible for monitoring the database sync status. We would need to modify this script to capture the lag value (e.g., in seconds, minutes, or transaction count) at the time the database is detected as out of sync.
• Alerting Changes: Update the alerting mechanism to include the lag value in the notification message. For example:
  • Current Alert: "Database is out of sync."
  • Proposed Alert: "Database is out of sync. Current lag: X [seconds/minutes/transactions]."

Benefits:

• Improved Response: Engineers will have a better understanding of the issue's severity, allowing for quicker and more appropriate responses.
• Proactive Monitoring: By monitoring the lag value, we can potentially identify issues before they escalate to a full out-of-sync state.
• Data-Driven Decisions: Provides a clear metric that can be tracked over time, helping to identify trends and improve overall database performance.

Request: Please review this proposal and assess the feasibility of implementing the suggested changes. If approved, I would recommend involving the engineering team to modify the existing script and update the alerting system accordingly.

Thank you for considering this enhancement. I'm happy to discuss further or provide additional details as needed.
