PostgreSQL Flexible Server metrics stopped collecting after January 1, 2026

Question

My PostgreSQL Flexible Server

stopped generating ALL metrics on January 1, 2026.

• Last metric data: January 1, 2026

What I've tried:

• Recreated diagnostic settings multiple times
• Verified Microsoft.Insights is registered
• Checked Azure Monitor directly - NO DATA after Jan 1
• Server is running fine, only metrics collection is broken

This appears to be a platform-level issue. Server is production and we urgently

need metrics for monitoring.

Answer 1

Hi Tripesh Dhoriya,

We have checked the backend logs and identified that the fluentd container, which is responsible for forwarding metrics, was in an unhealthy state. We have now restarted the container from our side.

Please allow up to one hour for the metrics pipeline to stabilize, and then check Azure Monitor again to confirm whether metrics are being collected and displayed.

Kindly let us know after one hour if the metrics are visible or if the issue still persists, and we will continue investigating if needed.

Hi Tripesh Dhoriya,

I see you're facing an issue with your PostgreSQL Flexible Server where metrics stopped collecting after January 1, 2026. That sounds concerning, especially since this is affecting your production environment.

Based on what you’ve shared, since you’ve already tried recreating diagnostic settings, verifying Microsoft.Insights registration, and checked Azure Monitor without detecting any data post-January 1, this indeed appears to be a platform-level issue. Below are some troubleshooting steps and considerations that may help:

Check the Server Configuration: Ensure that the server parameters for metrics collection are set correctly. For example, the parameter metrics.collector_database_activity should be set to ON to ensure database activity metrics are collected. If this is not the case, it can result in a lack of metrics.

Verify Diagnostic Settings: While you've recreated the diagnostic settings, ensure that all necessary diagnostics are enabled that pertain to metrics for your PostgreSQL Flexible Server.

Resource Health and Status: Monitor the resource health of your server in the Azure portal to check if it reports any degradation or maintenance activities that might impact metrics collection.

1. Review Azure Monitor Logs: Confirm that you are querying within the 30-day range limit in Azure Monitor. Sometimes, charts may display blank if the date range exceeds this limit.

To help you further, could you please clarify a few things:

• Can you confirm if the parameter for metrics collection is enabled (metrics.collector_database_activity)?
• Have you encountered any alerts or notifications in the Azure portal regarding your server or its metrics collection?
• Are there any resource health issues that you've seen in the Azure portal for your PostgreSQL Flexible Server?

Hope this helps, and let me know if you need any further assistance!

It seems that you are experiencing a significant issue with your PostgreSQL Flexible Server metrics collection. Since you have already tried recreating the diagnostic settings and verified that Microsoft.Insights is registered, here are a few additional steps you might consider:

1. Check Server Parameters: Ensure that the server parameter metrics.collector_database_activity is set to ON. This parameter is necessary for enabling metrics collection for database and activity statistics. If it is set to OFF, you will not receive any metrics.
2. Review Azure Monitor Configuration: Double-check the configuration of Azure Monitor to ensure that it is set up correctly to collect and route the metrics data. Sometimes, diagnostic settings can be misconfigured, leading to data not being collected.
3. Contact Azure Support: Since this issue appears to be persistent and affects your production environment, it may be beneficial to reach out to Azure Support for assistance. They can provide insights into whether there are any known platform-level issues affecting metrics collection.
4. Monitor for Updates: Keep an eye on Azure updates or announcements that may relate to metrics collection issues, as there could be ongoing maintenance or updates that affect service performance.

If the problem persists after these checks, it is likely a platform-level issue that needs to be addressed by Microsoft.
