No more events historized in the cloud database
Under Consideration
Hello
For 1 week, there are no more events historized in the cloud database.
All registered components are impacted.
Despite the update, the restart of the box, etc.
There have been no changes to the setting.
What for?
Thank you for the assistance.

Hello Luc,
It's frustrating when historical data suddenly stops being recorded. Based on the information you've provided, here's a breakdown of potential reasons why your cloud database might not be historizing events for the past week, despite updates and restarts, and with no configuration changes:
Possible Root Causes:
1. Cloud Provider Issues:
Service Outage or Degradation: Your cloud database provider might be experiencing an outage or performance degradation specifically affecting the data historization service. Check their status page for any reported incidents.
Maintenance: Scheduled or unscheduled maintenance on the database service could temporarily halt data writing or historization processes. Again, the provider's status page should have this information.
Quota Limits: You might have unexpectedly hit a storage quota or a write operation limit imposed by your cloud provider, preventing new data from being written and thus historized. Check your account usage and limits.
Billing Issues: If there are any issues with your billing or payment method with the cloud provider, they might have suspended certain services, including data writing.
2. Database-Specific Issues:
Internal Database Error: The underlying database instance might have encountered an internal error that is preventing it from processing or storing new historical data. Cloud providers usually have monitoring in place for this, but it's still a possibility.
Corruption: Although less likely with managed cloud services, there's a remote chance of data corruption affecting the historization process.
Resource Exhaustion (within your allocated instance): Even if you haven't hit cloud provider quotas, your specific database instance might be running out of resources like CPU, memory, or disk space, hindering write operations.
3. Application/Component Issues (Less Likely Given All Components are Impacted):
Data Sending Errors: While you mentioned no configuration changes, there could be a subtle issue in how your registered components are sending data to the cloud database. This is less likely if all components are affected simultaneously.
Authentication/Authorization Issues: Although you haven't changed settings, there might be an underlying issue with the authentication or authorization mechanisms used by your components to write to the database. Tokens could have expired, or permissions might have been inadvertently altered on the cloud side.
4. Network Connectivity Issues (Less Likely Given All Components are Impacted):
Intermittent Network Problems: While less probable for a consistent week-long issue across all components, there could be network connectivity problems between your components and the cloud database. However, this usually manifests as intermittent failures rather than a complete cessation of data.
Troubleshooting Steps:
Check Cloud Provider Status Page: This should be your first step. Look for any reported outages, maintenance announcements, or performance issues related to your database service and region.
Review Cloud Provider Monitoring and Logs: Access the monitoring dashboards and logs provided by your cloud database service. Look for any error messages, unusual resource consumption patterns, or anomalies that might indicate the problem.
Verify Database Instance Health: Ensure your database instance is reported as healthy and running by the cloud provider.
Check Resource Usage: Examine metrics like CPU utilization, memory usage, disk I/O, and storage space for your database instance. High usage could indicate a bottleneck.
Review Recent Activity Logs (if available): Look for any unusual activity or errors in the database's audit logs or activity logs.
Test Connectivity: From one of your registered components (if possible), try to establish a basic connection to the database to rule out fundamental network issues.
Examine Application Logs (though less likely): While you mentioned all components are affected, reviewing the logs of your applications might still reveal some clues or error messages related to database interaction.
Contact Cloud Provider Support: If you've gone through these steps and haven't found a solution, the next crucial step is to contact the support team of your cloud database provider. They have deeper access to the system and can diagnose underlying infrastructure issues. Provide them with all the details you've gathered, including the timeframe of the issue and the steps you've already taken.
Information to Provide to Cloud Support:
When you contact your cloud provider's support, be sure to include:
The specific cloud database service you are using (e.g., AWS RDS, Azure SQL Database, Google Cloud SQL, etc.).
The region where your database is located.
The exact timeframe when the historization stopped.
Details of the updates and restarts you performed.
Confirmation that no configuration changes were made.
Any error messages or unusual observations from your monitoring or logs.
The fact that all registered components are impacted.
By systematically investigating these potential causes and providing detailed information to your cloud provider's support, you should be able to identify the reason for the lack of historized events and get the issue resolved.
Good luck, Luc! I hope you can get this resolved quickly.
