According to Microsoft, this however should generally be left disabled. with setting pgaudit.log_level = DEBUG5 to a more noticeable log level won't work, as this setting is only enabled when pgaudit.log_client is enabled. Trying to work around this limitation e.g. It would be welcome if we could search for where errorLevel_s = "AUDIT" or similar. Unfortunately, pgAudit settings are specified globally and can't be specified at the database or role level.Īlso, it's unfortunate, that expensive string comparison is required when searching for audit messages. | where LogicalServerName_s = "psql-demo" However, you'll need to give it some time, until you see the first messages arriving (10 to 15 minutes in my experience).

Log into your server and run create extension pgaudit Īudit logs are now getting fed to the log analytics workspace.

Next, go to Monitoring > Diagnostic settings, enable logging for the category PostgreSQLLogs, and point it to an existing log analytics workspace.

Save your changes! WAIT! You are not done yet.

Alternative groups of statements can be configured, find more on the documentation.

Set pgaudit.log to WRITE, which will log INSERT, UPDATE, DELETE, TRUNCATE and COPY.

Set log_line_prefix from %t-%c- to %m-%c- so we get millisecond resolution in the logs.

Writing log files has some performance hit, why Microsoft recommends disabling it when feeding to Azure Monitor or other services.

Set the logging_collector to OFF so no more log files are getting generated.

From within the server parameters enabled PGAUDIT on the parameter shared_preload_libraries.

Microsoft already provides some good documentation on that, so I am only going to distill the high-level steps and important pieces here. Admittedly, the pgAudit extension can also be used with the Burstable compute tier, but as we'd like to feed data to a log analytics workspace we are stuck with the higher tiers. Second, we are also stuck with the General Purpose and Memory-optimized compute tiers when dealing with Azure Postgres Flexible Server instances.

Okay, let's get some work done! Audit logging with the pgaudit extensionįirst of all, for Azure Postgres Single Server instances, pgAudit is still in preview and can only be enabled with the general purpose and memory-optimized tiers. az monitor log-analytics workspace create \

I assume you already have a log analytics workspace in place, if that's not the case, here is an Azure CLI snippet to create one. ☝🏼 In case you know of any other options that work with Azure Postgres, please let me know! Audit logging with the pgaudit extension.The options that we are going to look at are: To mitigate this performance hit, we will disable the generation of log files and send data to a log analytics workspace for further analysis. When tracing is enabled, a lot of log data will be generated on heavily loaded databases, which has some performance implications. That's why I am going to demonstrate the options available to enable DML statement tracing on an Azure Postgres server instance. Unfortunately, Postgres doesn't provide features like Change Data Capture (CDC) or Change Tracking as MSSQL does. In other cases you only want temporal tracing to debug certain and otherwise difficult to tackle application problems.

This might be the case when you have to comply with government, financial, or ISO certifications and need to provide data to auditors.

There are situations where you want to trace certain SQL statements hitting your Azure Postgres database.
